Congressman Andrew may have caused the death of 800 sailors during WWII


I heard something about this a few years ago but just generalities that a congresscritter shot off his mouth during a press conference and released classified information that compromised operational assets.  No it wasn't the first time and yes it has happened since and funny that nothing seems to happen to those clowns.

     I saw this article chasing a car article...so I clipped it.

There is a reason certain military knowledge is classified: so it doesn't fall into the hands of the enemy. Congressman Andrew May didn't get the memo, as an ill-fated press conference led to the loss of an estimated 10 submarines and the deaths of 800 Navy crewmen.

The May Incident

The United States Navy was known for its successes following the country's entrance into WWII. Despite Japanese attempts to sink their vessels, the Allied forces managed to evade their attacks. This was because, at the time, the Balao-class of submarine could dive to depths of 400 feet, deeper than the Japanese set their depth charges.

In 1943, Andrew May, chairman of the House Military Affairs Committee, embarked on a tour of American military areas in the Pacific Theater, during which he was privy to a host of sensitive war-related information. When he returned that June, he held a press conference, where he revealed that American submarines only had a high survival rate because the Japanese charges were exploding at too shallow a depth 

The fallout of a blabbermouth

Not long after this news spread, the Japanese naval anti-submarine forces adjusted their charges to explode at a greater depth. This prompted Vice Admiral Charles A. Lockwood, commander of the US submarine fleet in the Pacific, to estimate that May's breach cost the Navy 10 submarines and resulted in the deaths of some 800 crewmen.

"I hear Congressman May said the Jap depth charges are not set deep enough," he said. "He would be pleased to know that the Japs set them deeper now."

The Navy's Pacific Submarine Fleet released a report following the press conference, in which it determined Japanese anti-submarine warfare (ASW) forces had failed to uncover the maximum depth the US submarine fleet could reach. However, it failed to state whether the Japanese had altered their depth charge attacks to deeper positions due to May's revelation.

Alleged war profiteering

The ill-fated press conference wasn't the only ding to Andrew May's career. During the early stages of the war, he became involved with two New York-based businessmen, Henry and Murray Garsson. Despite the pair having no prior arms manufacturing knowledge or experience, they sought to financially gain from the US involvement in the conflict by securing munitions contracts from the government.

On the pair's behalf, May used his position as chairman of the House Military Affairs Committee to contact Army ordnance and other government officials to obtain war contracts, favors, and draft deferments. For his efforts, he received substantial cash payments, information that was uncovered by a Senate investigating committee following the war.

This soon turned into a scandal, which only grew following testimony about the profit-taking of the Garssons' company and the defects in their munitions. It was found their 4.2-inch mortar shells had defective fuzes, leading to premature detonation. It's believed this resulted in the death of 38 American servicemen.

Paying for his actions... Maybe?

The fallout for Andrew May's many guffaws during the war included him losing re-election in 1946. He was then put on trial for federal bribery charges, and after less than two hours of jury deliberation was found guilty on July 3, 1947. Despite efforts to avoid incarceration, he was eventually sentenced to nine months in a federal facility.

Murray and Henry Garsson were also sentenced to prison terms.

Despite his be-smudged reputation, May continued to retain influence over politics within the Democratic Party. As such, he was able to secure a full pardon from President Harry Truman in 1952. He was, however, unable to revive his political career and thus returned to Kentucky to practice law until his death.

The Navy may keep the Nimitz Class of Carriers in Service longer.

 I snagged this from the 3rd party email, yeah I'm an Army guy that happens to know a bit about Navy stuff, especially Carriers.  I still think they need to go back to naming them for battles, and not politicians.  I am glad to see the Enterprise coming back though.

Nimitz-class carriers at sea

The U.S. Navy’s Nimitz-class carriers are about to turn 50. But given the demand for the carrier air wing and delays to the Nimitz-class replacement—the Ford-class—the USS Nimitz (CVN 68) itself is unlikely to retire as soon as expected.

The Navy’s fiscal 2023 budget has already called to extend the first-in-class CVN 68, commissioned in 1975, for another deployment cycle instead of decommissioning it in 2025 as previously planned. Service officials say the upcoming budget request could include a final decision on extending the next in the class, the USS Dwight D. Eisenhower, beyond its 2027 projected end-of-service date—though extending just that ship likely will not be enough.

“Extending Nimitz, extending Ike, it’s going to happen for every Nimitz-class carrier. At least one extension,” Vice Adm. Kenneth Whitesell, then-commander of Naval Air Forces, said during an Aug. 25 discussion at the Tailhook Symposium shortly before retiring from the service.

  • USS Nimitz extended, Eisenhower likely to follow
  • The service seeks Ford-class advanced procurement change
  • Repeated extensions could worsen strike fighter deficit

The future of the Nimitz class and oversight of ongoing issues facing production of the second Ford-class carrier, the USS John F. Kennedy, was a focal point of the discussion at the symposium. The Navy’s current plan for the Nimitz calls for $200 million for extension work as part of a 5.5-month maintenance schedule, according to a March 2023 report to Congress.

“Carriers are the linchpin of everything we do in naval aviation,” Director of Air Warfare Division N98 Rear Adm. Michael Donnelly said. “Our requirements are designed and aligned within our air wings to provide the capability out to the [combatant commands] for our ability to conduct the mission. Our ability to get the carriers out on time, whether it is new procurement or maintenance, is essential.”

The first-in-class USS Gerald R. Ford (CVN 78) is now deployed to the Mediterranean, about two years after it achieved initial operational capability. The Ford was extensively delayed and over budget, commissioning five years before the deployment and 15 years after its naming. Originally projected to cost $10.5 billion, the ship ended up costing $13.3 billion. Though it has advanced capabilities such as the new electromagnetic catapult system and improved weapons elevators, it is not yet able to bring on Lockheed Martin F-35Cs.

The Kennedy (CVN 79) was christened in December 2019 and is scheduled to be delivered in 2025, one year later than its prior expected delivery. The next in the class, the USS Enterprise (CVN 80), has also been affected by labor and supply chain issues, with its delivery date at least a year late as well, now scheduled for 2028.

The Navy has also faced issues with midlife servicing of its ships. The USS George Washington (CVN 73) came out of its Refueling and Complex Overhaul process in May, about two years later than expected. “We are dependent on Newport News, Virginia,” Whitesell said of issues in the Huntington Ingalls Industries Newport News Shipbuilding yard.

To address the Refueling and Complex Overhaul issues, the Navy is executing a performance-based contract for the process on the USS John C. Stennis (CVN 74). For new builds, the service is also looking at extended advance procurement contracts to have more of a lead time in the supply chain, switching to a three-year period from the current two years, Donnelly said.

“We have to look at our procurement strategies so that we are designing the budgeting and programming [and] buying those on the right centers [to] keep the momentum going in the industrial process,” he says.

Demand for carriers will not likely abate soon, as evidenced by the Ford and Eisenhower operating together in the Mediterranean. The Navy has been stressed in fulfilling its post-Cold War plan for a permanent 1.0 carrier presence on station in three hubs—the Western Pacific, the wider Middle East and Europe. To keep up this presence, the service needs 15 carriers—a 3:1 ratio because of maintenance and deployment process requirements. This plan was outlined in the 1993 Bottom-Up Review under then-Defense Secretary Les Aspin, but the service has been unable to meet it since, says Steven Wills, a navalist with the Center for Maritime Strategy at the Navy League.

Navy policy has shifted to the Fleet Response Plan, which focuses on being able to surge aircraft carriers forward when needed, as with the six carriers deployed for Operation Desert Storm and the five for Operation Iraqi Freedom. The current fleet size of 11 stresses this model, and with reactor time left on the ships, multiple extensions are possible, Wills says. “We beat our ships up. We’ve only got X amount of carriers, and constantly keeping one-third deployed, that’s rough,” he says.

In some ways, keeping the carriers active may be easier than decommissioning them, says Bryan Clark, a senior fellow and director of the Hudson Institute’s Center for Defense Concepts and Technology. Taking apart a massive, nuclear-powered aircraft carrier is a long, expensive and difficult job of which few companies are capable. Just three responded to a request for proposals to decommission the USS Enterprise. This process requires dismantling the nuclear reactor before shipping it to a nuclear waste storage facility, all while the ship takes up space in a dry dock.

As the Navy is planning its future carrier fleet size, it also faces math problems with its air wings. The service customarily had one more carrier air wing than its total number of carriers before deciding it did not need to keep that many aircraft. The Navy currently has nine air wings to serve on 11 carriers. “That means each air wing is getting worked at max availability,” Clark says.

Not all air wings are populated with enough strike fighters, he notes, and the Navy is not looking to buy more. Current F-35C production is capped by Lockheed Martin’s capacity and issues facing development of new capabilities, such as the Block 4 package. Early Super Hornets are reaching service-life caps, as Boeing’s Block III upgrade process has proven more time-consuming than originally expected, while the Navy wants to end new production.

For now, this means the service has been shuffling aircraft around its squadrons to populate those underway. It is a workable approach for now, but it is not necessarily sustainable, he says.

The Navy plans to address the potential aircraft shortages by leaning heavily into uncrewed aviation. The 2022 Navigation Plan authored by then-Chief of Naval Operations Adm. Mike Gilday, who has now retired, called for carrier air wings to be 60% uncrewed and 40% crewed. This plan hinges for now on the Boeing MQ-25 Stingray, slated to be the trailblazer for uncrewed carrier-based operations ahead of new programs such as Collaborative Combat Aircraft on which the Navy is working with the Air Force. Those uncrewed “loyal wingman”-type aircraft, which are to fly alongside F-35s and Next-Generation Air Dominance platforms, are expected to begin to be fielded by the end of the decade.

WWII and the Japanese Kamakaze movement

 

The nation of Japan was helpless before the invading force. They were outnumbered, and the enemy was about to land on the shores of the Imperial Home Islands. There was nothing left but to fight to the death against the savage invaders. But then, suddenly and without warning, a great wind came and destroyed the enemy fleet. The enemy, Mongols under Kublai Khan, had been destroyed by a sudden typhoon, a “Divine Wind” or “Kamikaze,” as it came to be known in Japanese history. In the year 1281, Japan had been saved by this help from above.

Nearly 700 years later, in 1944, the same situation faced Japan. It was not Mongols this time, but an enormous military force led by the United States that was threatening to invade Japan. The Western Allies had begun their inexorable advance against Japan three years earlier at New Guinea and Guadalcanal, and they were now more than halfway across the vast Pacific, aiming directly for Japan itself. In desperation, some Japanese leaders looked to another “Divine Wind” again to save them. This time, the Kamikaze would not be a typhoon, but swarms of suicide planes that were to be unleashed at the advancing allies.

Kamikaze pilots
A kamikaze pilot salutes as he receives his orders for a “divine wind” mission. It is estimated that over 
1,200 pilots (out of 2,314) lost their lives on such missions.

The concept of individual suicide was accepted within Japanese society, particularly among those descended from the warrior, or Samurai, class. Suicide was generally accepted as the way to atone for failure, and ritual suicide, also known as seppuku and harakiri, was common among the military of Japan. It would appear repeatedly during the Pacific war, beginning at Guadalcanal and lasting to, and even after, Japan’s surrender.

But mass suicide was something else. Throughout the war, individual Japanese, particularly pilots whose planes were too badly damaged to return to base and being culturally unable to accept a surrender to the enemy, would fly their damaged aircraft into some enemy target, be it a ship or a ground target. These men were presumed to have been granted a direct passage to an honored place in heaven for their actions.

 

Suicide as a doctrinal military tactic, however, did not enter Japanese military policy until October 1944. By then, the Americans were invading the Philippines and the Palau Islands, threatening to cut off Japanese lines of supply from the Far East. Without those supplies, Japan could not sustain its war effort much longer. All attempts to stop the American advance had so far failed, and, as in 1281, Japan was growing increasingly desperate. Once again, the accepted solution was the Kamikaze.

The origins of the modern Kamikaze are traced to Luzon, in the Philippines, in October 1944. The Americans were about to invade those islands, and the Japanese were preparing to meet that invasion. Captain Rikihei Inoguchi of the Imperial Japanese Navy Air Forces was at Clark Field discussing attack plans against the approaching American invasion force. As a senior staff officer of the 1st Air Fleet, he had been assigned the job of organizing the air defenses of the Philippines.

While speaking with Commander Asaichi Tamai, commanding the 201st Air Group, he was joined suddenly by Vice Adm. Takijiro Ohnishi, the recently appointed commander of Japanese Naval Air Forces in the Philippines. Joined by some squadron leaders, the group sat down to listen to Admiral Ohnishi’s instructions.

Admiral Ohnishi was himself a pilot and a long-time advocate of naval aviation in Japan. He had helped plan the Pearl Harbor attack and had been a protégé of Admiral Isoroku Yamamoto. As a staff officer, Ohnishi had long been involved in discussions in Tokyo over the use of suicide operations, arguing against them. But the continued defeats in the Pacific and the loss of vital resource territory seemed to have changed his opinion by the time he was appointed to command the 1st Air Fleet in the Philippines.

Admiral Ohnishi began by stating the obvious: Japan’s situation was critical. He then explained that the Imperial Japanese Navy was about to launch an all-out attack on the American fleet off Leyte. But the Japanese fleet had no air cover of its own; the 1st Air Fleet on Luzon would have to provide that air cover. He had orders to protect the fleet for at least one week, keeping the American aircraft carriers from launching strikes that would cripple or destroy the oncoming Japanese fleet.

The problem was that the 1st Air Fleet had only 30 serviceable aircraft on Luzon. How could such a small force hold back the hundreds, perhaps thousands, of American planes coming to Leyte Gulf?

Admiral Ohnishi presented his solution. He told the assembled pilots and staff officers, “In my opinion, there is only one way of assuring that our meager strength will be effective to a maximum degree. That is to organize suicide attack units composed of Zero fighters armed with 250-kilogram bombs, with each plane to crash-dive into an enemy carrier…What do you think?”

Despite a broken elevator and wings riddled with bullet holes, a Mitsubishi A6M  “Zeke” Kamikaze plane makes its death plunge toward the carrier USS Essex off Okinawa, May 14, 1945. Japan’s efforts to cripple the American invasion of Okinawa brought about the mass employment of suicide missions.

Silence initially replied to the admiral’s proposal. Captain Inoguchi remembered, “No one spoke for a time, but Admiral Ohnishi’s words struck a spark in each of us. Indeed, ‘body-crashing’ (taiatari) tactics had already been used by Navy pilots in air-to-air combat against big enemy bombers, and there were many fliers in the combat air units who had urged that the same tactics be employed against enemy carriers.”

The group then discussed whether a fighter plane armed with a 250-kilogram bomb would be enough to disable or even sink an American aircraft carrier. They acknowledged that accuracy would be greater with a pilot guiding the weapon, including his own plane, to the target. Commander Tamai, the senior flying officer present, agreed that the plane and bomb together would be enough to at least disable any American aircraft carrier it hit.

Commander Tamai then held a meeting with his pilots, and came back to say, “The 201st Air Group will carry out his proposal. May I ask that you leave to us the organization of our crash-dive unit?” The Japanese Kamikaze program of 1944 had begun.

Commander Tamai assembled his enlisted pilots and explained the new proposal to them. Every one of the 23 pilots joyfully agreed to participate in the Kamikaze program. Returning to his staff, Commander Tanai and Captain Inoguchi discussed how best to organize the unit. They wanted an officer, preferably a graduate of the Japanese Naval Academy at Etajima, to lead the first attack.

After some discussion, Lieutenant Yukio Seki was selected as the attack leader. When approached by Inoguchi and Tamai, Lieutenant Seki responded, “You absolutely must let me do it.”

Discussions followed regarding the force’s organization. A name was suggested, and soon the new unit was called Shimpu, another Japanese word for Kamikaze. Admiral Ohnishi approved the plans, organization, and men for the new unit.

On the morning of October 20, 1944, the Shimpu attack group ate breakfast and then assembled for their final instructions. Admiral Ohnishi gave them a speech encouraging them to succeed, and the 24 pilots were prepared to go. But that was easier said than done.

The initial missions had to be aborted: mechanical failure grounded aircraft, enemy combat air patrols kept the Japanese grounded, and bad weather prevented takeoff. It wasn’t until the morning of October 25 that Lieutenant Seki and his group finally launched their mission.

The Shimpu encountered a support carrier group known to the Americans as “Taffy 3.” These Americans had already been attacked by Imperial Japanese Navy surface forces days earlier in Leyte Gulf. Now, one of the Shimpu group dove out of the sky at the escort aircraft carrier USS Kitkun Bay (CVE-71).

Sailor Ron Vaughn, an 18-year-old lookout on Kitkun Bay, spotted the plane as it climbed, rolled, and plunged down on his ship, aiming for its flight deck. The ship’s antiaircraft guns opened fire and damaged the plane as it dove. One round crumpled the tail section, causing it to veer off course. But the plane hit the water close aboard, damaging the ship and causing scores of casualties.

Another Shimpu pilot dove on the USS Kalinin Bay (CVE-68) and hit the deck of the carrier; two others were driven off by the antiaircraft fire.

American fighter pilots immediately raced to the scene to defend their home carriers. Despite their efforts, three more Shimpu planes attacked the escort carrier USS St. Lo (CVE-63) from above; the first Japanese plane was shot down by fire from the St. Lo.

The second suffered the same fate, but this aircraft drew the American’s attention away from the third aircraft, which was following the ship and simply pulled up, nosed over, and crashed into the vessel. Witnesses remembered that the plane sliced through the flight deck, igniting fuel and ammunition in the hanger area below that deck. One sailor insisted that he saw a bomb drop from the aircraft an instant before the plane crashed into the ship.

The impact doomed the St. Lo. Explosions rocked the ship from bow to stern. Damage-control sailors raced around to save their ship, but it was no use. Thirty minutes after she was hit, the St. Lo sank. With her went 140 American sailors. She was the first “official” kill of the Kamikaze attack force.

Admiral Ohnishi committed suicide after Japan’s surrender.

Meanwhile, the Kalinin Bay was hit again and severely damaged; the USS White Plains (CVE-66) and USS Kitkun Bay were both narrowly missed. Although all these three ships were damaged, casualties remained few.

Ashore, the Japanese awaited the results of the first Kamikaze attack. Commander Tadashi Nakajima was at his base on Cebu Island when three Mitsubishi A6M Zero fighter planes landed there. Out of the first to land came Chief Warrant Officer Hiroyoshi Nishizawa, who ran up to Commander Nakajima and made his report: Of the five Kamikazes and four escorts, he reported, Lieutenant Seki had hit a carrier, and a second Kamikaze hit the same ship, which soon sank. The third Kamikaze struck another carrier, setting it afire. The fourth plane crashed into a light cruiser which “sank instantly.” The fifth Kamikaze disappeared. Three of the four escorts managed to return to Cebu.

The report was a fiction. In fact, only the USS St. Lo was sunk, with the Kitkun Bay and White Plains damaged. No light cruiser was struck on October 25. This report, inaccurate as it was, was forwarded to Tokyo, which accepted it at face value and broadcast it to the Japanese nation as a great victory by the newly established Kamikaze Corps.

Believing a great success had been achieved from a small group of aircraft, the Kamikaze program continued on October 26. For the expenditure of five Kamikazes and two escorts, the light carrier USS Suwannee (CVE-27) was slightly damaged. Earlier, the USS Santee (CVE-29) had been damaged by a Kamikaze that approached so swiftly that no guns had been able to fire before it slammed into the ship.

By now, the standard operating procedure for the launching of Kamikazes had been established. First, they would await a report from a search plane that would locate, identify, and report on an American carrier group. Often, these reports were inaccurate, and a mission would have to be aborted when no ships were found by the Kamikaze pilots. Each Kamikaze flight had at least two escorting fighters to assist them in getting past the American combat air patrols that protected the American carrier battle groups.

Weather was, of course, always a factor. How many Kamikazes were assigned to any one mission depended upon the conditions reported by the scouts. Approaching their targets, the Kamikazes would increase their speed to make their approaches while the escorting fighters protected them from the combat air patrol. The signal, “All Planes Attack!” was given by the flight leader’s raised arm, and each pilot picked his own target, then plunged down toward it.

The deeds of the “Kamikaze Special Attack Corps,” one of the names for the new Kamikaze force, had by now reached Tokyo. Emperor Hirohito had responded to this new tactic with a message to his naval aviators through Admiral Ohnishi. The message read, “Was it necessary to go to this extreme? They certainly did a magnificent job.”

Crewmen aboard the carrier USS Belleau Wood off the Philippines pour water on aircraft and burning flight deck after a Kamikaze strike, October 30, 1944. The carrier USS Franklin, also hit by a suicide plane, burns in the distance.

Captain Inoguchi, who was with Admiral Ohnishi in Manila, felt that the first sentence of the Emperor’s words were something of a criticism of Ohnishi’s new project, and Ohnishi appeared quite upset upon reading this message. But he remained determined to gain the Emperor’s favor by increasing his success.

Kamikaze strikes continued against American ships throughout the Philippine Campaign, including the invasion of Luzon and the clearing of the southern Philippines.

Meanwhile, the idea spread throughout the Imperial Japanese Navy and was taken up by the Imperial Japanese Army, as well. One of the chief reasons for this was the lack of skilled pilots. At the outbreak of the war, Japanese pilots had been the best of the best. But over the three years that the war had thus far progressed, attrition had whittled down those expert pilots to a precious few, many of whom where now busy training their replacements.

But the training of new pilots took time and fuel, neither of which the Japanese had in abundance. A Kamikaze pilot, though, did not need the in-depth training that a pre-war fighter pilot needed. He only needed to be able to take off, fly a distance, and crash into an enemy ship. Even formation flying was optional, although helpful.

As one historian has written, “Loss of aircraft and veteran pilots and shortages of fuel led to a reliance on suicidal Kamikaze units by 1944, made up of largely green, ill-trained aviators and a mélange of planes.”

The Kamikaze idea had by now spread far and wide among the Japanese military. Soon Kamikaze Corps were being established in Japan itself. Those forward bases under attack by the advancing Americans were often provided with some “Special Attack Units.” Soon this title was expanded to other suicidal methods of defeating the enemy.

One such method was known as the “Kaiten”—a manned suicide torpedo that was intended to sneak into American-held harbors and sink enemy ships at anchor. Then came the “Ohka” (Cherry Blossom)—a human-piloted bomb released from a carrying aircraft over the target and flown into that target by the pilot.

The first major warship sunk by the Kamikazes was the carrier USS St. Lo, which was hit off Samar in Leyte Gulf, October 25, 1944. One hundred forty Americans died.

There were also suicide explosive speedboats (“Shin’yo” or Sea Quake)—small plywood craft filled with explosives and driven by a crew of one or two into enemy ships as they approached the shore of a Japanese base. Hundreds of these were later captured unused in the Philippines and Okinawa.

At the war’s end, near Okinawa, even the Imperial Japanese Navy’s super-battleship, the IJN Yamato, was turned into a form of Kamikaze. (See WWII Quarterly, Spring 2020.) But none of these other efforts achieved either the fame or the success of the Imperial Japanese Navy’s “Kamikaze Special Attack Corps.”

Some ships just seemed to draw the attention of the Kamikazes. One such ship was the Australian heavy cruiser HMAS Australia. Perhaps because her appearance different from that of American ships, she was hit repeatedly, although her near-identical sister ship, HMAS Shropshire, who often sailed alongside her, was never hit. Some called her “the Kamikaze Magnet.”

HMAS Australia had been in the war since the early days of 1939 and had earned herself an enviable battle record. But she just couldn’t seem to shake the Kamikazes. She was first targeted in Leyte Gulf on October 21, 1944, leading some Australians to claim that she was the first victim of the Kamikazes, and not the USS St. Lo.

That day, the attacking aircraft was seen to be hit by antiaircraft fire and almost crashed into the water. But the plane recovered, and despite further heavy antiaircraft fire, punched into the port side of the heavy cruiser. This sounds more like a “body-crashing” (Taiatari) tactic than a Kamikaze attack, but the strike cost the ship her captain, Captain Emile F. V. Dechaineux, along with five officers and 23 enlisted sailors. Scores of others were wounded.

The ship returned to the war after repairs in November, well after the Kamikaze had begun in earnest. In early January 1945, the HMAS Australia was attacked no less than five times by Kamikazes. On January 5, she was struck by a Zero, which hit her amidships; 25 men on the gun crews died and another 30 were wounded. Damage was slight, and she remained on station with a gunfire support group off Leyte.

The next day she was hit again, at the middle smokestack on the starboard side, killing 14 and wounding 26. Damage was minimal, and she remained on station. January 7 was a quiet day, but January 8 was not.

A Japanese bomber came in, chased by four fighters of the combat air patrol. The enemy went down barely 20 meters off the HMAS Australia’s port side. It skidded into the cruiser’s hull, but caused no damage or casualties. Less than 20 minutes later, another Japanese bomber appeared and repeated the same events. But this time, the bomb that the plane was carrying went off and ripped a large hole in the cruiser’s port side, flooding two compartments. Once again, there were no casualties. Asked if he wanted to withdraw for repairs, Captain J.M. Armstrong refused and remained on station.

By January 9, the Sixth U S. Army was wading ashore on the main Philippine Island of Luzon, and HMAS Australia was offshore in support. Eight Kamikazes came in searching for the invasion fleet, and two headed for the Australia. One of these hit the USS Mississippi (BB-41) and the other hit the Australia at her foremast, crushing her forward smokestack and rendering the forward fire room inoperable. With a hole in her side, her forward fire room out of action, and her speed reduced, the Australia had had enough. This time she accepted the offer to retire for repairs, once again with no additional casualties.

Kamikazes appeared in almost every battle after Leyte. But by far their most successful and deadly campaign came against the American invasion of Okinawa. Here, Marines and the soldiers of the Tenth U. S. Army faced a determined defense, one of whose primary objectives was to draw the American fleet into a position that would make it vulnerable for attacks from nearby Japan.

One of the negative by-products of rushing pilots through an abbreviated training program to qualify them as Kamikazes was that they had poor ship identification skills. This error was felt most by the “small boys”—the auxiliary ships that often accompanied the major fleet units to supply, fuel, and otherwise provide succor to them when needed.

These included some described by their titles, including LCS(L)3, or Landing Craft Support (Large) Mark 3. Developed from the original Landing Craft Infantry, or LCI, some had been modified with rockets, machine guns, 20mm and 40mm guns, and other assorted armament which, to the untrained Japanese pilot desperately trying to find a target while avoiding the combat air patrol and antiaircraft fire, were often mistaken for combat vessels such as destroyers and even cruisers. As a result, these flat-bottomed, diesel-powered, 160-foot-long ships often became the targets these Japanese pilots were seeking.

The U.S. Navy’s Fifth Fleet, under Admiral Raymond Spruance, was the largest in the world (535 warships), but its position at Okinawa was exposed. It was committed to the island for all manner of support and supply duties, which made its ships stationary targets for the Japanese, who no longer had to guess where the American fleet could be found.

To protect the fleet, the Americans had established a series of “radar picket” posts around the island to give early warning of the Japanese approach. Instead, these soon presented to the Japanese aviators’ lonely targets, ripe for attack. The radar-picket destroyers and destroyer escorts were supported by various “little boys,” which were known at these posts as “pall bearers,” since they spent so much time picking up survivors out of the water, making them an inviting target for the Japanese.

The Japanese reaction began slowly. On March 20, 1945, the Japanese Imperial General Headquarters came up with a major offensive involving Kamikaze pilots called Ten-Goō(“Heavenly Operation”). Tasked with leading this operation was Vice Adm. Matome Ugaki, commander of the IJN Fifth Air Fleet.

After gathering every flyable plane he could find, no matter its obsolescence or original purpose, Ugaki assembled 3,000 of them at bases across Kyushu. The plan, dubbed Operation Kikusui, was simple: guided by the few experienced pilots Japan had left, the suicide pilots would be sent out in waves to find the American ships and destroy them. The veteran pilots would then return to their bases to pick up another group and repeat the process.

On April 6, 1945, the Japanese struck in force with Kikusui No. 1 against the U.S. Navy’s Task Force 58 and the British Royal Navy’s Task Force 57, the latter operating between Formosa and Okinawa. Some 700 planes—half of them suicide planes—took off and went hunting for the Allied fleets.

The first to be attacked at Okinawa were the destroyers USS Bush (DD-529) at picket station number 1, the Colhoun (DD-801) at picket station number 2, and the Cassin Young (DD-793) at picket station number 3. Although the three destroyers put up a deadly screen of antiaircraft fire, enough enemy planes got through to sink both the Bush and Colhoun; the Cassin Young barely escaped the same fate—for now.

Elsewhere, the destroyers USS Howorth (DD-592) and Hyman (DD-732) were severely damaged, while the destroyers USS Leutze (DD-481) and Morris (DD-417) were knocked out of the war. Destroyer USS Mullany (DD-528) was so badly damaged that she had to be scrapped. Destroyer USS Newcomb (DD-586) was also sent home for good, as was the USS Rodman (DD-456).

The list of sunken ships included LST-447 and support ships Logan Victory and Hobbs Victory. The minesweeper USS Defense (AM-317) went down as well. The USS Haynsworth (DD-700) was damaged, as was the USS Feiberling (DE-640). And this was only one day’s success for the Kamikazes.

The suicide pilots also tried attacking two American carriers, the Bennington (CV-20) and Belleau Wood (CV-24), but both ships escaped with minimal damage.

Both sides suffered badly during Kikusui No. 1. The Japanese had hit 17 American ships, sunk or knocked 11 out of the war, and killed over 360 sailors. The Japanese, in turn, had lost over 350 planes and pilots—planes and pilots that could not be replaced.

The Australian heavy cruiser HMAS Australia, showing damage incurred on October 21, 1944, was struck so many times by suicide pilots that she earned the nickname “the Kamikaze magnet.” She was never sunk, however.

The next day the massive battleship IJN Yamato steamed toward Okinawa and her doom at the hands of the American pilots from Task Force 58.

The loss of Yamato did not stop the Japanese from continuing their suicide attacks on the Allied fleets. After suspending operations for a few days due to bad weather, on April 11, Kikusui No. 2 was launched—a two-day assault by 185 suicide planes accompanied by 150 escorts. The carrier USS Enterprise (CV-6) was the first to feel the enemy’s sting, which knocked it out of action for two days while repairs were made. The carrier Essex (CV-9), too, was hit but not sunk.

On April 12, another dozen ships were hit, with the destroyer USS Mannert L. Abele (DD-733) and LCS(L)-33 going down. On that same day, the Cassin Young was in the middle of the fight for her life, as she was targeted during a heavy Kamikaze raid. Her gunners shot down five aircraft, but a sixth crashed into her foremast, exploding in midair only 50 feet above the ship.

Surprisingly, only one man was killed, but 58 were wounded, many seriously. Although badly damaged, Cassin Young made it to Keramo Retto under her own power and would return to Okinawa in May after repairs. She would be attacked again in July, suffering major damage and loss of life, but she refused to be sunk. (The ship is today on display at the Charleston Navy Yard in Boston, Massachusetts.)

Each day, one or more ships were being hit and disabled, if not sunk. The radar picket posts were the most vulnerable, set far from other support and usually exposed to the incoming enemy air raids before anyone else. The raids went on daily throughout April, May, and June, and ship after ship was lost to the incessant aerial attacks.

CinCPac Admiral Chester W. Nimitz grew increasingly concerned and pushed Lt. Gen. Simon B. Buckner, commanding the Tenth U. S. Army, to move quickly to clear Okinawa of enemy resistance so that he could withdraw his ships from Japanese target practice. But the Japanese ashore were as determined as those in the air, and the battle continued well into June.

One the worst attacks by the Kamikazes was that suffered by the USS Laffey (DD-724), stationed at radar picket post number 1 on April 16. The first USS Laffey had been sunk during the naval battles for Guadalcanal. The current USS Laffey, laid down in 1942, had already established herself as a worthy successor to her namesake and had participated in the naval support during the landings in Normandy. On April 16, 1945, she would prove her worth once again.

Soon after dawn, 50 enemy planes were closing in on the fleet, and Laffey’s radar picked up four enemy planes approaching her. Three were shot down by Laffey’s antiaircraft fire, and the fourth was shot down by the guns on board Lieutenant Howell Chickering’s nearby LCS(L)-51. Carrier-borne Corsairs were slicing through the enemy formation, downing as many planes as they could.

A fifth plane attacked Laffey, only to be shot down as well. Then a sixth streaked in, strafing the ship as it approached. Several casualties resulted from the strafing before this plane crashed into the ship at the after funnel, jamming the fire-control radar.

A seventh aircraft smashed into the forward gun mount and then ricocheted off the ship, leaving no serious damage. An eighth plane was shot down as it attacked. But a ninth Zero used that attack to approach undetected and crashed into the starboard 20mm battery, damaging nearby 40mm batteries, starting a gasoline fire, and setting off the ammunition.

Almost immediately, a tenth plane hit the ship’s fantail, knocked out the aft 5-inch gun, and damaged three 20mm antiaircraft guns there. Plane number 11 dropped its bomb first near the depth-charge rails before crashing into the aft 5-inch gun mount, already damaged by a previous plane.

Plane number 12 dropped its bomb close aboard, jamming the rudder to a hard-left position. The Laffey now had no operable guns in the rear of the ship. The captain, Lt. Cmdr. Frederick J. Becton, now had a ship on fire and with no guns protecting her stern. The Japanese quickly took advantage of this weakness, and two more planes came in from astern, crashing again into the 5-inch mount number 53 and killing several of the crew who were fighting fires there.

Plane number 15 was shot out of the sky as it approached from the port quarter. A pursuing combat air patrol Corsair was so close on his heels that he hit the ship’s mast and ditched nearby. But this attack knocked out the ship’s radar.

Plane number 16 was next in line and was shot down over the ship by the combat air patrol, but not before its bomb shredded the ship’s bow with shrapnel, knocking out power to 5-inch mount 52, which continued to operate manually.

Plane number 17 was shot down, and plane number 18 was disintegrated by a shell from mount 52. Plane number 19 was also shot down, by mount number 51. A twentieth plane came in through the smoke off the Laffey and dropped its bomb on mount number 53 before breaking off the ship’s yardarm. It was then splashed by the combat air patrol.

Plane number 21 also dropped its bomb, knocking out two 20mm antiaircraft mounts before being shot down by the combat air patrol. A final attacker was also taken out by the combat air patrol.

The USS Laffey was miraculously still afloat but in serious trouble. It was down at the stern, the rudder was jammed, and most of its guns were disabled. Fortunately, the hull and engines had not been damaged. She had been hit by six Kamikazes, damaged by two other near misses, struck by three bombs, and had other close calls. She lost 31 killed and 72 wounded, but the fires were soon under control and the flooding stopped. She was towed to a repair base off Okinawa and, after service during the Korean War, would eventually end up as a memorial at Patriot’s Point, Charleston, South Carolina. Both LCS(L)s supporting her also survived, although with significant casualties.

But, like a swarm of angry wasps, the Kamikazes kept coming. As the battle progressed, their attacks and numbers began to thin out. Since Okinawa was lost and the next invasion would no doubt be at Japan itself, the Japanese decided to hoard their remaining Kamikaze planes and pilots for the final battle.

One of the greatest tragedies to befall the American fleet was that of the carrier USS Bunker Hill (CV-17), the flagship of Vice Adm. Marc A. Mitscher’s Task Force 58. On May 11, the carrier was on station 76 miles east of Okinawa when a Japanese “Zeke” fighter suddenly appeared out of the cloud cover.

Having just been refueled with nearly two million gallons of high-octane aviation fuel, the Bunker Hill was a floating Molotov cocktail waiting for a spark. The Zeke crashed into the flight deck, which was brimming with 30 planes waiting to take off; in the hangar deck below were 48 more that had been fueled and armed.

While the planes on deck exploded and burned, another Kamikaze dashed in and slammed into the ship’s control center, known as “the island.” Crewmen sprang into action in a valiant, but ultimately futile, effort to contain the blaze. Other ships pulled alongside to aid in the effort but they, too, stood no chance against the roaring inferno.

In the end, 346 officers and men out of the ship’s complement of 3,000 lost their lives, 43 were missing, and another 264 were injured. The charred wreck of the carrier managed to return for repairs to Bremerton, Washington, via Pearl Harbor, but it would never fight again.

At the end of the war, the Japanese themselves compiled a recapitulation of the record of the “Kamikaze Special Attack Corps.” They recorded that, of the 2,314 planes dispatched (including escorts), 1,086 returned. For the 1,228 planes “expended,” they claimed 81 ships sunk and 195 damaged, for a total of 276 ships.

Postwar records indicate that the correct figures are 34 ships sunk, including three light carriers and 13 destroyers. Of the 195 ships the Japanese claimed as damaged, they had actually damaged 288 ships, including 16 fleet aircraft carriers, three light carriers, and 17 escort carriers. It should be noted that several ships, like the HMAS Australia and USS Laffey, were hit repeatedly but not sunk. So, the Japanese claim of a total of 276 enemy ships sunk or damaged by Kamikazes is understated. In fact, they hit 322 allied ships, sinking 34. It was not the “Divine Wind” of 1281, but it was a respectable effort, nevertheless.

But, despite all her efforts to halt the American invasion of Okinawa, Japan had shot her bolt. Once Okinawa fell, she had very little chance of preventing a full-scale invasion of the Home Islands.

As the intelligence officer of the Fifth Fleet put it, “The Japanese are defeated, but we have not yet won the victory.”  The Kamakaze and the resistance on Iwo Jima and Okinawa with the suicides of the civilians jumping to their death sealed the fate of the Japanese, and the casualties that the Americans suffered prompted President Truman to use the Atomic Bombs to force a surrender.

The Navy PBR Boats in Vietnam

 I remembered seeing a PBR at Patriots Point when my son was in the cub scouts, the entire place is worth the visit and the time.  Especially when the scouts can stay overnight on the U.S.S. Yorktown.  granted it was in Enlisted quarters with the steel decks but still it ranked up there in the "cool" factor.  I remember seeing a PBR on the TV for the first time in the Movie "Apocalypse Now" when Martin Sheen character rode in one to go kill the rogue colonel.  I had remembered asking my Dad if he had rode in one of those in the course of his duties and he had commented that he did as part of his duties with the "Tropic Lightning"during his first tour.  All he said was "it was interesting". 

 


The U.S. Navy deployed a variety of small boats to South Vietnam during the Vietnam War, but perhaps the best known of these is the river patrol boat. The “patrol boat: riverine,” or Navy PBR, was the first watercraft built for the so-called brown water navy in Vietnam. During the height of the conflict, Navy personnel scouted the rivers and canals of the sprawling Mekong Delta for communist guerrilla forces, arms, and ammunition. In addition to patrolling, Navy PBRs participated with Navy and Army troops in hit-and-run raids, reconnaissance patrols, and day and night ambushes.

The origins of the Navy PBR can be traced to Hatteras Yacht Company of New Bern, North Carolina, which in 1965 responded to a U.S. Navy request for a prototype for a small patrol boat to operate in shallow waters. The Navy’s Bureau of Ships sought a prototype for what it designated as “patrol boat, river” that could achieve speeds between 25 to 30 knots, draw only nine inches of water, and skim over sandbars. The boat would be crewed by four sailors and have heavy armament. Its armament would consist of a twin .50-caliber machine gun in an armored forward turret, as well as a .30-caliber mounted gun in the aft section. Additionally, the boat would need to be able to reverse direction, turn on a dime, and come to a quick stop from full speed within a few boat lengths.

Hatteras stated its intention to build a 28-foot fiberglass hull powered by water-jet pumps as opposed to screw propellers. The water pumps would enable the new boat to go into shallow water. The Navy put the PBR contract out for bid, and eight companies responded with bids. United Boat Builders of Bellingham, Washington, ultimately won the contract. The company built the PBR around its existing 31-foot fiberglass hull. This boat became PBR Mark I. The Navy initially requested 120 PBRs. Eighty of the Navy PBRs were assigned to the Mekong Delta and 40 to the Rung Sat Special Zone south of Saigon

The dark-green Mark I was powered by twin General Motors 220-horsepower diesel engines and water jet pumps supplied by Jacuzzi Brothers. The jet pumps shot out streams of water from nozzles located below the waterline on the stern. The jets of water had sufficient thrust to propel the boat. Steering was accomplished by rotating the nozzles left or right. For stern propulsion, a so-called u-gate slipped down over the nozzles and rerouted the flow 180 degrees, which propelled the boat backward. When fully loaded, the boat topped out at 14,600 pounds and could reach a speed of 25.7 knots.

The builder installed ceramic armor designed to deflect bullets up to .30 caliber around the coxswain’s flat and at the weapons stations. The boat’s heaviest weapon, the twin .50 caliber, was installed in an open turret in the bow. In the fantail area, a single machine gun was affixed to a pedestal. Amidships on both sides of the boat were open-ended receptacles to which could be mounted either an M-60 machine gun or an MK-18 grenade launcher. A similar receptacle built into the aft machine mount allowed an MK-18 to be piggybacked with the stern machine gun.

In addition to the mounted machine guns, the crew also took along M16 rifles, M-79 grenade launchers, handguns, and hand grenades. The boat came equipped with a Raytheon 1900/N radar system and two AN/VRC046 FM radios.

The hull could be repaired quickly and easily. It was designed so that enemy rounds would pass through it without exploding. There was no solid surface that would cause detonation.

The Navy PBR Mark I was not immune to problems. When fully loaded, the Mark I drew 22.5 inches of water, which greatly exceeded the nine inches originally requested. Added to that, the Mark I never attained the desired speed of 25 knots. This was because the jet pumps put a heavy strain on the boat’s diesel engines. Added to this, Styrofoam blocks that kept the boat high in the water frequently became waterlogged as a result of seepage through the hull.

The four-man crew for the Navy PBR included a first-class petty officer who served as the boat’s captain. Owing to battle casualties and other reasons, both chiefs and second-class petty officers also captained the boats. The other crew members were an engineman, a gunner’s mate, and a seaman.

Large numbers of communist forces operated in the Mekong Delta region, not only because it contained half of South Vietnam’s population and was responsible for half of the country’s rice production, but also because of its close proximity to Saigon. The communists routinely transported men and supplies through its 3,000 miles of waterways. As they did so, the communists actively recruited in the region and extorted funds from the local people to finance their operations. Communist forces carried out an estimated 1,000 small-scale attacks each month in 1966 on government posts and villages in the Mekong Delta.

One of the fundamental tactics developed for the Navy PBRs was to operate in pairs while conducting patrols. The two boats would travel in a column, with the trailing boat following 400 to 600 yards behind the lead boat. This way the two boats were close enough to cover each other. The crews conducted patrols and searches during the day and at night. When searching a vessel at night, the boat conducting the search approached the suspect craft at high speed, illuminated the vessel, and ordered all occupants to show themselves on the near side of the watercraft.

The PBRs sought to stay in the middle of the channel to maintain as much distance between the boat and shore as possible in case enemy forces were lurking in the foliage. During a search, the crew of the PBR kept a .50-caliber machine gun trained on the shore opposite the vessel being searched in case it was fired upon from behind.

The U.S. Navy launched Operation Game Warden on December 18, 1965, and established a River Patrol Force in South Vietnam to maintain military curfews and implement the interdiction program in both the Mekong Delta and Rung Sat Special Zone. As part of the program, PBR crews routinely stopped and searched suspect sampans to see if they were transporting guerrilla troops or smuggling military provisions for communist forces.

The River Patrol Force, also known as Task Force 116, was composed of a number of river divisions. Each division had two 10-boat sections. The River Patrol Force operated from LSTs (landing ships, tank) that served as floating bases complete with troop quarters. The PBRs served as the core watercraft for these riverine divisions. The first batch of Navy PBRs arrived in country in March 1966 during the continuing buildup of U.S. forces in South Vietnam.

To furnish close air support for the PBRs in the delta, the Navy activated Helicopter Attack Squadron 3 at Vung Tau. In addition, Navy SEAL platoons operated with the River Patrol Force, giving it the ability to conduct clandestine intelligence operations.

Navy PBR crews routinely used tape recorders and loudspeakers to announce curfew hours and issue instructions to Viet Cong who might wish to defect. They also performed humanitarian missions, such as transporting medical personnel to isolated villages and wounded villagers to field hospitals.

After their initial experience using their new watercraft, PBR crews made some key improvements to the weapons systems on the boats. First and foremost, they replaced the .30-caliber machine gun aft with a .50-caliber to reduce the necessity of having to carry two different types of ammunition. They also added an M-18 grenade launcher and stripped most of the armor from the forward machine-gun position to improve the gunner’s field of vision.

 


A joint service Mobile Riverine Force began operating in June 1967. The principal organizational elements of the force were Navy Task Force 117 and the U.S. Army’s Ninth Infantry Division’s Riverine Forces. The riverine force was capable of deploying 150 miles from its base within 24 hours. It possessed a 5,000-man combat force that could engage the enemy immediately upon arrival at its destination. The riverine force’s initial anchorage was at Vung Tau on the coast southeast of Saigon, but it eventually moved to Dong Tam in the upper Mekong Delta.

The advent of the Mobile Riverine Force in the delta marked a shift in the balance of power in the region, with the allies gaining superiority over the communists. The Riverine Force fought five major actions during 1967, in which it killed 1,000 communist troops. The enemy frequently fought in battalion strength in the larger of these engagements. In addition to small arms, they used a variety of heavy weapons, including machine guns, rocket launchers, and recoilless rifles.

The Mobile Riverine Force conducted a series of major combat operations, including Coronado I through XI from 1967-1968, Giant Slingshot from 1968-1969, and Sealords from 1968-1971. The purpose of these operations was to isolate and destroy Viet Cong and North Vietnamese units and dismantle their infrastructure in the Mekong Delta and the Capital Military District.

In September 1967, the River Patrol Force obtained a new, completely modified Navy PBR, the Mark II. The new model had larger, improved water jet pumps made from a metal less prone to corrosion. Additionally, the boats boasted a new circuitry system for the forward twin .50-caliber machine guns. The boat was also capable of much higher speeds than its predecessor. Not long after the introduction of the Mark II, a new Alfa model was introduced with even more upgrades. By early 1969 there were 250 river patrol boats in South Vietnam, including 130 Mark II and Mark II Alfa PBRs, as well as 120 Mark I PBRs.

Communist troops attacked more than 100 of South Vietnam’s cities and towns on January 31, 1968, during the Vietnamese Lunar New Year holiday known as Tet. The size and the ferocity of the Tet Offensive put U.S. and South Vietnamese forces on the defensive.

In the Mekong Delta region, the communists attacked 64 district capitals. The Tet Offensive resulted in an uptick in riverine units being used for fire support, troop transport, and amphibious assault. Up until Tet, PBRs typically called for naval or aerial assistance and then withdrew until help arrived before re-engaging the enemy; however, the Navy loosened the rules of engagement during Tet: If the patrol officer in charge of the PBR decided his boat could stand and fight, he had the discretion to do so. Another change in doctrine occurred regarding where the PBRs patrolled. Before Tet, PBRs generally stayed in the main rivers of the delta region, but during the communist offensive they began to operate in canals and other narrow waterways.

The PBRs in the Vietnam War played a key role in riverine operations and achieved positive combat results. In the course of their patrols and operations, U.S. Navy riverine forces killed 3,000 communist soldiers and sank, damaged, or captured upward of 6,500 boats.

Some key statistics offer insight into the hazards of PBR service. One of every three PBR sailors was wounded during his tour of duty. Yet this in no way deterred the volunteers who clamored to serve aboard the boats. Volunteers for the PBRs came from all U.S. Navy rates, ratings, and ranks. Furthermore, morale among the PBR crews remained high throughout the conflict.

For these reasons, the Navy PBR crews that served during the Vietnam War were highly respected by sailors and soldiers alike. “We were volunteers [and] patriots,” said Petty Officer Jere Beery, reflecting on his service on a PBR. “We were gung-ho as hell. We looked for trouble.”
