"The Bard of Warriors has arrived " Tom Clancy April 12 1947 to October 1 2013



In Vahalla the Warriors are drinking mead and regaling each other with tales of glory when the door opens and a figure walks in, one of the warriors eyes the newcomer and exclaims "By Oden, the Bard of Warriors has arrived!"  The Vikings immediately make a place at the table and hand the newcomer a horn of mead and all make a toast to the newcomer "Welcome to Vahalla where all warriors live forever!




     Thomas Leo "Tom" Clancy, Jr. (April 12, 1947 – October 1, 2013) was an American author best known for his technically detailed espionage and military science storylines that are set during and in the aftermath of the Cold War, along with video games which bear his name for licensing and promotional purposes. Seventeen of his novels were best-sellers, with over 100 million copies in print.[3] His name was also a brand for similar movie scripts written by ghost writers and many series of non-fiction books on military subjects and merged biographies of key leaders.

     I first became a fan of Tom Clancy back in the mid 80's, he wrote 2 books  that I got hold of the first one was "Hunt for Red October", the second one was "Red Storm Rising.  The second one I read while I was patrolling the 1K zone between West Germany and East Germany and Czechoslovakia.  He had the ability to make all his books seem real, it kinda scared the crap out of me, I kept expecting the 8th Guards Army and GSFG to roll over us, we in the Cav were viewed as "Speedbumps" and we were expected to die in place and give NATO a chance to call out the forces to defeat the Russians.    Funny how things have changed....and yet remain the same.  I remember on 9-11 when my wife called me and woke me up, I was on night shift at Ford Motor Company and she called me to tell me that a commercial plane hit the trade center, and my first reaction was " when did you start reading Tom Clancy?"  I didn't believe it until I turned on the TV and saw the second plane hit the tower and I knew that we were attacked and at war.

     I was a continual fan of his books and I always knew that he believed in American exceptional-ism and that we as Americans would prevail in the end.    
     We lost Vince Flynn and now Tom Clancy, The literary world for people on the conservative side is lessened.

Another Segment of equipment from "Red Storm Rising"



This is a continuation of my "Red Storm Rising" articles that I am doing., the next piece of equipment was the "F-19 "Ghostrider" or the "Frisbee".  I thought that Tom Clancy talked about a stealth fighter/bomber before the unveil of the F117 Night Hawk of Desert Storm fame.  In the book, the "frisbee's performed the first mission by NATO doing a preemptive strike against the Soviet Mainstays that were flying over East Germany monitering the NATO forces.  The Frisbee's came in low through the ground clutter and came under the Mainstays and shot them down opening up the night sky for NATO's fighter bombers that immediately went in and decimated bridged, supply dumps and Command and control centers guaranteeing that the 2nd echelon of the Soviet forces were not able to support the first echelons that were starting to engage the NATO forces.  This gave NATO control over the night sky for the duration of the conflict.


In his 1986 novel Red Storm Rising, Tom Clancy featured the "F-19A Ghostrider" (nicknamed "Frisbee" by the pilots and crew) as a secret weapon used to combat a Soviet invasion of Germany. This vehicle was considerably more capable than the F-117, being a supersonic fighter rather than a subsonic precision bomber. The F-19A as described in the book featured underwing hardpoints for various ordnance, including air-to-air missiles and BLU-107 Durandal runway-cratering bombs. The aircraft also has circular wings instead of angular ones, hence the nickname

Since the unification of the numbering system in 1962, U.S. fighters have been designated by consecutive numbers, beginning with the F-1 Fury. F-13 was never assigned to a fighter due to superstition, though the designation had previously been used for a reconnaissance version of the B-29. After the F/A-18 Hornet, the next announced aircraft was the F-20 Tigershark. The USAF proposed the F-19 designation for the fighter, but Northrop requested the "F-20" instead. The USAF finally approved the F-20 designation in 1982.The truth behind this jump in numbers is Northrop pressed the designation "F-20" as they wanted an even number, in order to stand out from the Soviet odd numbered designations. Despite this, the designations F-17, F-21, and F-23 were not skipped.
Throughout most of the 1980s, "F-19" was thought to be the designation of the stealth fighter whose development was an open secret in the aerospace community. When the actual aircraft was publicly revealed in November 1988, its designation was revealed to be F-117.


Another rumor was that F-19 is really the designation of some other super-secret project, one so black that it will not be revealed for many years.
One more version was part of a deliberate plot by the Air Force to confuse Soviet intelligence by hoodwinking them into expending so much effort in trying to find out information about a plane that does not exist.

   Now I will talk about one of my favorite airplanes, the A-10, we Army guys love the A-10, I have seen what the airplane has done to soviet equipment, it is literally hell on enemy Armor.  In the book, the A-10 was used to savage the Soviet Armor formations, the FAC would ask NATO armor to go after the mobile SAM systems like the ZSU-23-4  or the SA-6 missile system for they have the ability to shoot down the A-10 as they would make runs on the Soviet Armor.  According to the book, the Soviets called the A-10 the "flying cross" because the shape reminded them of the Orthodox cross that is prevalent in soviet churches. 

The Fairchild Republic A-10 Thunderbolt II is a single-seat, twin turbofan engine, straight wing jet aircraft developed by Fairchild-Republic for the United States Air Force (USAF). Commonly referred to by its nicknames Warthog or Hog, its official name comes from the Republic P-47 Thunderbolt, a World War II fighter that was effective at attacking ground targets. The A-10 was designed for close air support (CAS) of friendly ground troops, engaging armored vehicles and tanks, and providing quick-action support against enemy ground forces. It entered service in 1976 and is the only production-built aircraft that has served in the USAF that was designed solely for CAS. Its secondary mission is to provide forward air controller – airborne (FAC-A) support, by directing other aircraft in attacks on ground targets. Aircraft used primarily in this role are designated OA-10.


The A-10 was intended to improve on the performance of the A-1 Skyraider and its poor firepower. The A-10 was designed around the 30 mm GAU-8 Avenger rotary cannon. Its airframe was designed for durability, with measures such as 1,200 pounds (540 kg) of titanium armor to protect the cockpit and aircraft systems, enabling it to absorb a significant amount of damage and continue flying. Its short takeoff and landing capability permits operation from airstrips close to the front lines, and its simple design enables maintenance with minimal facilities. The A-10 served in the Gulf War (Operation Desert Storm), the American intervention against Iraq's invasion of Kuwait, where the A-10 distinguished itself. The A-10 also participated in other conflicts such as Operation Urgent Fury in Grenada, the Balkans, Afghanistan, Iraq, and against ISIL in the Middle East.



The A-10A single-seat variant was the only version produced, though one pre-production airframe was modified into the YA-10B twin-seat prototype to test an all-weather night capable version. In 2005, a program was started to upgrade remaining A-10A aircraft to the A-10C configuration with modern avionics for use of precision weaponry. The U.S. Air Force had stated the F-35 would replace the A-10 as it entered service, but this remains highly contentious within the Air Force and in political circles. With a variety of upgrades and wing replacements, the A-10's service life may be extended to 2040, although plans call for it to be retired starting in 2022 after being replaced.


The A-10 has a cantilever low-wing monoplane wing with a wide chord. The aircraft has superior maneuverability at low speeds and altitude because of its large wing area, high wing aspect ratio, and large ailerons. The wing also allows short takeoffs and landings, permitting operations from primitive forward airfields near front lines. The aircraft can loiter for extended periods and operate under 1,000 ft (300 m) ceilings with 1.5 mi (2.4 km) visibility. It typically flies at a relatively low speed of 300 knots (350 mph; 560 km/h), which makes it a better platform for the ground-attack role than fast fighter-bombers, which often have difficulty targeting small, slow-moving targets.
The leading edge of the wing has a honeycomb structure panel construction, providing strength with minimal weight; similar panels cover the flap shrouds, elevators, rudders and sections of the fins. The skin panels are integral with the stringers and are fabricated using computer-controlled machining, reducing production time and cost. Combat experience has shown that this type of panel is more resistant to damage. The skin is not load-bearing, so damaged skin sections can be easily replaced in the field, with makeshift materials if necessary. The ailerons are at the far ends of the wings for greater rolling moment and have two distinguishing features: The ailerons are larger than is typical, almost 50 percent of the wingspan, providing improved control even at slow speeds; the aileron is also split, making it a deceleron.

The A-10 is designed to be refueled, rearmed, and serviced with minimal equipment. Its simple design enables maintenance at forward bases with limited facilities. Also, most repairs can be done in the field. An unusual feature is that many of the aircraft's parts are interchangeable between the left and right sides, including the engines, main landing gear, and vertical stabilizers. The sturdy landing gear, low-pressure tires and large, straight wings allow operation from short rough strips even with a heavy aircraft ordnance load, allowing the aircraft to operate from damaged airbases, flying from taxiways or even straight roadway sections.

 The front landing gear is offset to the aircraft's right to allow placement of the 30 mm cannon with its firing barrel along the centerline of the aircraft. During ground taxi, the offset front landing gear causes the A-10 to have dissimilar turning radii. Turning to the right on the ground takes less distance than turning left. The wheels of the main landing gear partially protrude from their nacelles when retracted, making gear-up belly landings easier to control and less damaging. All landing gears are hinged toward the aircraft's rear; if hydraulic power is lost, a combination of gravity and aerodynamic drag can open and lock the gear in place.

The A-10 is exceptionally tough, being able to survive direct hits from armor-piercing and high-explosive projectiles up to 23 mm. It has double-redundant hydraulic flight systems, and a mechanical system as a back up if hydraulics are lost. Flight without hydraulic power uses the manual reversion control system; pitch and yaw control engages automatically, roll control is pilot-selected. In manual reversion mode, the A-10 is sufficiently controllable under favorable conditions to return to base, though control forces are greater than normal. The aircraft is designed to fly with one engine, one half of tail, one elevator, and half of a wing missing.


The cockpit and parts of the flight-control system are protected by 1,200 lb (540 kg) of titanium aircraft armor, referred to as a "bathtub". The armor has been tested to withstand strikes from 23 mm cannon fire and some strikes from 57 mm rounds. It is made up of titanium plates with thicknesses from 0.5 to 1.5 inches (13 to 38 mm) determined by a study of likely trajectories and deflection angles. The armor makes up almost 6 percent of the aircraft's empty weight. Any interior surface of the tub directly exposed to the pilot is covered by a multi-layer nylon spall shield to protect against shell fragmentation.  The front windscreen and canopy are resistant to small arms fire.

The A-10 was envisioned to fly from forward air bases and semi-prepared runways with high risk of foreign object damage to the engines. The unusual location of the General Electric TF34-GE-100 turbofan engines decreases ingestion risk, and allows the engines to run while the aircraft is serviced and rearmed by ground crews, reducing turn-around time. The wings are also mounted closer to the ground, simplifying servicing and rearming operations. The heavy engines require strong supports, four bolts connect the engine pylons to the airframe. The engines' high 6:1 bypass ratio have a relatively small infrared signature, and their position directs exhaust over the tailplanes further shielding it from detection by infrared homing surface-to-air missiles. The engines and exhausts are angled upward by nine degrees to cancel out the nose-down pitching moment that would otherwise generate from being mounted above the aircraft's center of gravity and avoids the need to trim the control surfaces to prevent pitching.

To reduce the likelihood of damage to the A-10's fuel system, all four fuel tanks are located near the aircraft's center and are separated from the fuselage; projectiles would need to penetrate the aircraft's skin before reaching a tank's outer skin. Compromised fuel transfer lines self-seal; if damage exceeds a tank's self-sealing capabilities, check valves prevent fuel flowing into a compromised tank. Most fuel system components are inside the tanks so that fuel will not be lost due to component failure. The refueling system is also purged after use. Reticulated polyurethane foam lines both the inner and outer sides of the fuel tanks, retaining debris and restricting fuel spillage in the event of damage. The engines are shielded from the rest of the airframe by firewalls and fire extinguishing equipment. In the event of all four main tanks being lost, two self-sealing sump tanks contain fuel for 230 miles (370 km) of flight.

Although the A-10 can carry considerable disposable stores, its primary built-in weapon is the 30 mm GAU-8/A Avenger autocannon. One of the most powerful aircraft cannons ever flown, it fires large depleted uranium armor-piercing shells. The GAU-8 is a hydraulically driven seven-barrel Gatling-type cannon designed specifically for the anti-tank role with a high rate of fire. The cannon's original design could be switched by the pilot to 2,100 or 4,200 rounds per minute; this was later changed to a fixed rate of 3,900 rounds per minute. The cannon takes about half a second to come up to speed, so 50 rounds are fired during the first second, 65 or 70 rounds per second thereafter. The gun is accurate enough to place 80 percent of its shots within a 40-foot (12.4 m) diameter circle from 4,000 feet (1,220 m) while in flight. The GAU-8 is optimized for a slant range of 4,000 feet (1,220 m) with the A-10 in a 30-degree dive.

The fuselage of the aircraft is built around the cannon. The GAU-8/A is mounted slightly to the port side; the barrel in the firing location is on the starboard side at the 9 o'clock position so it is aligned with the aircraft's centerline. The gun's 5-foot, 11.5-inch (1.816 m) ammunition drum can hold up to 1,350 rounds of 30 mm ammunition, but generally holds 1,174 rounds. To protect the GAU-8/A rounds from enemy fire, armor plates of differing thicknesses between the aircraft skin and the drum are designed to detonate incoming shells. The AGM-65 Maverick air-to-surface missile is a commonly used munition, targeted via electro-optical (TV-guided) or infrared. The Maverick allows target engagement at much greater ranges than the cannon, and thus less risk from anti-aircraft systems. During Desert Storm, in the absence of dedicated forward-looking infrared (FLIR) cameras for night vision, the Maverick's infrared camera was used for night missions as a "poor man's FLIR". Other weapons include cluster bombs and Hydra rocket pods. The A-10 is equipped to carry laser-guided bombs. A-10s usually fly with an ALQ-131 ECM pod under one wing and two AIM-9 Sidewinder air-to-air missiles under the other wing for self-defense.

Some of the Ships used in Tom Clancy's "Red Storm Rising"

I am a huge fan of Tom Clancy and his book "Red Storm Rising", is one of my favorite books.  The first time I read this book, was in 1986 and we were at a border camp near "Hof" Germany and our job was to patrol the border and be basically a trip wire if GSFG crossed the border and unified Germany and Western Europe under the Soviet umbrella. man talk about scaring the crap out of me...
We  patroled in a "Jeep" or a truck, utility 1/4 ton 4x4. M151A2


Border Jeep, Note the bumper ID, Mine was "BDR2"   
I though that was ironic finding this pic on "google"
We had a foot locker full of laws rockets, extra ammo, grenades, and claymores.  We were expected to "die in place" to give the USAREUR units in the rear time to get in the field to stop the Soviets before the Rhine.  We called ourselves "Speedbumps for GSFG".  The duty was sobering but I wouldn't trade the experience for anything.  The things I learned there held me in good stead when I got deployed to the Gulf in 1990.


   I will focus on some of the ships on this post and will continue to add more post to the series :)

  Right now I will focus on a couple of the ships used in the book, they were HMS Battleaxe and USS Reuban James.

HMS Battleaxe was a Type 22 frigate of the Royal Navy.


The length of the first four Type 22s was dictated by the dimensions of the undercover Frigate Refit Complex at Devonport Dockyard. The ships would be powered by a combination of Olympus and Tyne gas turbines in a COGOG (COmbined Gas turbine Or Gas turbine) arrangement. Machinery spaces were sited as far aft as possible to minimise shaft lengths. The after configuration was dictated by the requirement for a large hangar and a full-width flight deck.
Weapons fit was determined by the primary ASW role combined with a perceived need for a general purpose capability. The principal ASW weapons systems were the ship's Lynx helicopter and triple torpedo tubes (STWS), with 2087 towed array sonar a key part of the sensors fit. Air defence was provided in the form of two 'six-pack' launchers for the Seawolf (GWS 25) point-defence missile system. Surface warfare requirements were met by the provision of four Exocet SSM launchers, the standard RN fit at that time. A pair of L/60 Bofors were fitted in the first batch for patrol and junk busting on summer Indian Ocean deployments, but proved expedient in the Falkland were T22 captains considered they interfered with concentrating on Seawolf setup.
The Broadsword design was unique to the Royal Navy in lacking a main gun armament. Although some of the Leander class frigates had lost their main gun armament during upgrades, Broadsword was the first to be designed from the beginning without a large calibre gun turret. This changed with the introduction of the Batch III ships.
Ordering of Type 22s proceeded slowly, in part because of the comparatively high unit cost of the ships. The unit cost of the last Type 12Ms had been about £10m; Type 21s cost around £20m each; when the first Type 22s were ordered, unit costs were estimated at £30m though, by the time that the first ship (HMS Broadsword) commissioned in 1979, inflation had driven this figure up to £68m, which was far higher than the cost of the contemporary Type 42s (HMS Glasgow, also commissioned in 1979, cost £40m).
 The ships top speed was 30 knots and displacement was 4400 tons.  I figured that was fully "kitted" out with fuel, ammo and crew.
4 x single MM38 Exocet SSM
2 x sextuple GWS25 Seawolf SAM
2 x twin Oerlikon 30mm/75
2 x single Oerlikon/BMARC 20mm GAM-B01
2 x triple STWS Mk.2 torpedo tubes

 131 metres (430 ft) (length)
14.8 metres (49 ft) (beam)
6.1 metres (20 ft) (draught)

2 x Rolls-Royce Olympus TM3B
2 x Rolls-Royce Tyne RM1C


USS Reuben James (FFG-57), an Oliver Hazard Perry-class guided missile frigate, was the third ship of the U.S. Navy named for Reuben James, a boatswain's mate who distinguished himself fighting the Barbary pirates. Her crew totaled 201 enlisted, 18 chief petty officers, and 26 officers.

 In the book Commander Edward Morris and Capt Doug Perrin RN make a good team as they prosecute submarines attacking the convoys crossing the Atlantic that are resupplying NATO as they try to show down the Soviet Army near Hannover and other locations.  They make good use of a Seahawk "F" variant commanded by Jerry O'Malley, USN – helicopter pilot, USS Reuben James. Past master sub-hunter and anti-submarine warfare tactician. Goes by the code name "Hammer" when he is flying. Incredibly skilled with the dipping sonar of his Seahawk helicopter.


After the SH-60B entered service, the Navy began development of the SH-60F to replace the SH-3 Sea King. Development of this variant began with the award of a contract to Sikorsky in March 1985. An early-model SH-60B (Bu. No. 161170) was modified to serve as a SH-60F prototype. The company was contracted to produce seven SH-60Fs in January 1986 and the first example flew on 19 March 1987.
The SH-60F primarily serves as the carrier battle group's primary antisubmarine warfare (ASW) aircraft. The helicopter hunts submarines with its AQS-13F dipping sonar, and carries a 6-tube sonobuoy launcher. The SH-60F is unofficially named "Oceanhawk". The SH-60F can carry Mk 46, Mk 50, or Mk 54 torpedoes for its offensive weapons, and it has a choice of fuselage-mounted machine guns, including the M60D, M240D, and GAU-16 (.50 caliber) for self-defense. The standard aircrew consists of one pilot, one co-pilot, one tactical sensor operator (TSO), and one acoustic sensor operator (ASO).

Profile in the E-3 Sentry (AWACS)

 This post was supposed to drop yesterday, but I ran into problems, For some reason, "Blogger" decided to unpublish a bunch of my older posts that I did years ago and the common thread seemed to be "Barky The LightBringer" or "Obummer"  and "Obungler"and the religion of Islam. and I didn't even use the election of 2012 or the election of 2016 as a reference.   For those of y'all that have been reading my post for many years, know that I spent a LOT of time on that subject, it was a happy hunting ground for me and many other bloggers, kinda like shooting fish in a barrel for us.  Well I had to spend a lot of time appealing the decisions and got most of them restored except for 3 of them.


Back in 2017 I did a bunch of of  "Red Storm Rising" post, and I really enjoyed writing them, it was a lot of fun for me.  The book is one of my all time favorite books, and I considered Tom Clancy a "Warrior Bard" and anybody from the Military community in the 1980's and 90's knew who Tom Clancy was.   Anyway this popped up in my "Aviation News feed, it is a profile on the E-3 and I thought it was pretty good and I shamelessly "Nicked it".

Credit: U.S. Air Force

[Editor’s Note: More profiles of major military aircraft programs are available to Aviation Week Intelligence Network subscribers at awin.aviationweek.com.]

The E-3 Sentry Airborne Warning and Control System (AWACS) is an airborne early warning and control (AEW&C) aircraft based on the Boeing 707-320B commercial airliner. The aircraft is powered by four Pratt & Whitney TF33-PW-100A jet engines supplying 20,500 lbf. (91.2 kN) or General Electric CFM56-2 turbofans supplying 24,000 lbf. (106.8 kN) of thrust at sea level each.

Program History

Features

The E-3 carries a pulse-doppler mechanically scanned S-band radar in a 30-ft. rotating dome suspended 11 ft. above the fuselage by a pair of struts. This radar is the AN/APY-1 or APY-2, depending on the E-3 variant. The U.S. Air Force (USAF) quotes the radar’s effective range at “more than” 217.2 nmi (402.3 km).

The “rotodome” also contains an identification friend-or-foe (IFF) antenna and antennas for the aircraft’s datalinks. Originally, the E-3 used the Link 4A (TADIL-C) datalink to communicate with fighter aircraft. To facilitate a 360-deg. field of view, the dome is hydraulically rotated at 6 rpm. When not operating the dome rotates at 1/24 of this speed to heat the lubricant and prevent it from congealing.

The E-3 can operate beyond 29,000 ft. (8,840 m). USAF also says the E-3 can operate more than 5,000 nmi (9,260 km) from its base. This estimate goes for aircraft equipped with the TF33. Boeing, for its part, quotes an endurance of six hours at a mission radius of 870 nmi (1,610 km).

The E-3 uses an IBM CC-1 mission computer. Most of the avionics are air cooled, though the radar transmitter has a liquid cooling system. Nine Situation Display Consoles (SDCs) are carried for operators, yielding a typical aircrew of 13. Later variants carry additional consoles and can deploy with more operators.

The aircraft features a refueling slipway above the cockpit to enable in-flight refueling by a boom-type refueler.

 

Variants

EC-137D

The EC-137D was the designation for E-3 prototypes, two of which were built by and retained by Boeing. These were later upgraded to the E-3B standard.

E-3A [Block 10/15]

E-3A aircraft come in two configurations, the “Core” Block 10 and the “Standard” Block 15. Block 15 features the APY-2 radar, an upgraded APY-1 with sea-search capability. Counting the prototypes, the first 25 E-3s are Block 10s. All aircraft produced thereafter carry the APY-2.

E-3B [Block 20]

The E-3B is a modernized E-3 variant upgraded to the Block 20 standard. Block 20 includes five new Situation Display Consoles (SDCs), the IBM CC-2 computer, radio teletype capability and maritime surveillance capability for the APY-1. Five new UHF radios and one HF radio also were fitted, and the UHF radios included feature HAVE QUICK frequency-hopping capability. Block 20 and Block 25 modifications began in 1984.

E-3C [Block 25]

The E-3C is a further upgrade standard similar to the E-3B, but for aircraft with the APY-2.

E-3D

The E-3D is the E-3 variant procured by the United Kingdom. It features CFM56-2 engines, the APY-2 and the Loral EW-1017 ESM system.

E-3F

The E-3F is the E-3 variant procured by France. Like the E3-3, it uses the CFM56-2 and carries the APY-2. It was not initially equipped with an ESM system but received one after delivery.

E-3G [Block 40/45]

E-3s receiving Block 40/45 modifications are known as E-3Gs.

KE-3

The KE-3 is a tanker/cargo derivative of the E-3. It does not feature any elements of the E-3 mission system but has a ventral refueling boom, wingtip drogue pods, a cargo door and a cargo floor. These aircraft are powered by the TF-33.

RE-3A

The RE-3A is a signals intelligence derivative of the KE-3. It features the Tactical Airborne Surveillance System (TASS), a sensor system mounted in two large rectangular fairings on either side of the forward fuselage. These fairings are similar in shape to those seen aboard the USAF RC-135V and RC-135W Rivet Joint. Other small antennas also are present on the underside of the airframe.

RE-3B

The RE-3B is a more advanced derivation of the RE-3B.

Upgrades

Block 30/35

The first significant series of E-3 modifications brought aircraft to the Block 30/35 standard. The new Block includes electronic support measures (ESM) capability, the Joint Tactical Information Distribution System (JTIDS) to support the Link 16 datalink, GPS and new computers. These features improve location accuracy for targets passed over Link 16 or Link 11 by a factor of 200.

The main Block 30/35 contract was awarded to Boeing in May 1987. Other upgrades, including GPS capability, were added later. In 1994 Boeing was awarded a $16.8 million contract from NATO and a $127 million contract from the U.S. to procure ESM integration kits for their E-3s. The first Block 30/35 upgrades were completed in October 1995, and the program was finished in 2001.

Radar System Improvement Program (RSIP)

The RSIP program began at the direction of USAF in 1989. It was intended to increase the sensitivity of the E-3 radar system and would bring USAF and NATO APY-1 and APY-2 radars to a common standard. The upgrades improved the electronic countermeasures (ECM) resistance of the system, replaced operators’ consoles, introduced a new radar processor and included new software. NATO joined the program in 1994 as operational test and evaluation of the upgrades was well underway. The UK also joined the program in 1996 when it awarded a contract to Boeing to upgrade all seven of its E-3Ds.

Full rate production began in 1997, with the first kits delivered in 1998. The U.S. installed the kits at Tinker AFB during regularly programmed depot maintenance cycles. NATO kits were installed by Daimler-Benz Aerospace (later EADS and now Airbus) in Germany. In February 2002, France awarded a $133 million contract to Boeing for its own RSIP kits.

Extend Sentry

Starting in October 1994, the Air Force began a series of E-3 upgrades intended to allow the aircraft to serve to 2025. This predominately included obsolescence management and maintainability improvements

Diminishing manufacturing sources Replacement of Avionics for Global Operations and Navigation (DRAGON)

DRAGON is an E-3 upgrade program jointly pursued by NATO and the USAF. It is intended to replace the E-3’s analog cockpit avionics with a glass cockpit and improve compliance with air traffic management mandates from ICAO and the FAA. This includes ADS-B (Out) capability, a new weather radar, an enhanced ground proximity warning system (EGPWS) and Mode 5 IFF. DRAGON has been pursued concurrently with Block 40/45, and the USAF received the first modified aircraft in January 2017. The upgrades reduce the minimum flight crew from four to three by eliminating the navigator.

Block 40/45

The Block 40/45 upgrade brings E-3s to a common E-3G standard and represents an all-around modernization of the E-3 mission system. The upgrades were pursued concurrently with the E-10, the Boeing 767-based replacement for the E-3 and E-8 J-Stars. Block 40/45 testing began in 2006. The upgrade program cost approximately $2.6 billion. It became vitally important after the E-10 program was terminated in 2010.

The upgrade includes the Telephonics AN/UPX-40 IFF system, which provides enhanced clutter rejection over the old system. It also includes new MIDS JTRS Link 16 radios. Most critically, it replaces the computing backend for the aircraft. The flight computer is replaced with a Red Hat Linux-based system and the operator stations are replaced with new Microsoft Windows-based consoles.

Block 40/45 also includes the Internet Protocol Enabled Communications (IPEC) program. IPEC fields an INMARSAT based satellite communications capability on the E-3, enabling full internet connectivity in flight. USAF uses this for IP chat, email and air tasking order and airspace control order dissemination. Aircraft with IPEC carry a rectangular SATCOM antenna just aft of the wing center section.

AWACS Communications Integration Program (ACIP)

ASIP will field a Mobile User Objective System (MUOS) and Second Generation Anti-Jam Tactical UHF Radio for NATO (SATURN) radio capability to the USAF E-3 fleet. The FY23 budget provides $95.2 million for ASIP from FY23 through FY25.

Production and Delivery History

The first E-3s were delivered to the USAF in March 1977. Production terminated in 1992.

United States

Initial operating capability (IOC) for the U.S. E-3 fleet was declared in April 1978. The last aircraft were delivered to the Air Force in 1984. Thirty-four were procured in total. On Sept. 22, 1995, a USAF E-3 77-00354 crashed in Alaska. Of the remaining 33 aircraft, 31 remain in service. Twenty-seven of these are based at Tinker AFB, Oklahoma under Air Combat Command, while the remaining four are based at Kadena AB, Japan, and Elmendorf AFB, Alaska, under Pacific Air Forces.

The FY15 USAF budget request reduced the active inventory from 31 to 24 aircraft, but the inventory was restored in budgets from FY17 through FY19. The see-sawing inventory disrupted the Block 40/45 upgrade program but in FY19 a contract was awarded for the seven remaining Block 30/35 aircraft.

The FY23 Air Force budget proposal decreases modernization funding in view of the Air Force decision to procure a replacement AEW&C aircraft. This includes terminating Block 40/45 funding from FY23 through the FYDP.

The Air Force included $227 million in RDT&E funds for an E-3 replacement in its FY23 budget request. The funds will be used to procure a prototype, which the Air Force says will be delivered in 2027. Another prototype would be bought in FY24 with a production decision in FY25. The Air Force formally selected the Boeing E-7A Wedgetail on April 26, 2022. All prior sales of E-7s have been conducted through Direct Commercial Sales rather than Foreign Military Sales – meaning different intellectual property, financial and other regulations would apply to a prospective USAF acquisition.

The Wedgetail is a Boeing 737-700 carrying Northrop Grumman’s L-band Multi-role Electronically Scanned Array (MESA). This electronically scanned radar is a generational leap over the APY-1/2 capability and is fully mature, having served with the Royal Australian Air Force for over ten years.

This lengthy development phase is interesting in light of the maturity of the E-7 capability and of new Air Force plans to dramatically cut the E-3 fleet in the near term. The FY23 budget request envisions divestment of 15 of the Air Force’s 31 E-3s in FY23 and FY24. The Air Force previously intended to keep its 33 E-3s in service until 2035. It is unclear if Congress will authorize E-3 divestment since it will generate a capability gap spanning the rest of the decade, if not longer. Rep. Tom Cole (R-Okla.), for example, said at a May 13, 2023, House Appropriations defense subcommittee hearing that the E-3 retirement plan was a “big risk” and one that “is not wise to take.” For more on the replacement plan, see Aviation Week’s program profile on the E-7 .

Also noteworthy is a lone ex-RAF E-3D bought by the U.S. Navy in June 2021. This E-3D will have its mission equipment removed and will be used by the Navy as a trainer for E-6B Mercury flight crews. Procuring a dedicated trainer will increase the operational availability of the E-6B fleet by reducing the requirement for these aircraft to fly training sorties. For more information on the E-3D acquisition and the E-6 fleet, see Aviation Week’s program profile on the E-6.

NATO

The North Atlantic Treaty Organization (NATO) decided in December 1978 to acquire a joint AEW&C capability. It opted to procure 18 E-3As. The first was delivered in January 1982, and all were delivered in E-3A Block 15 configuration. One of these was lost in an accident in 1995 and another was parted out for spares in 2015. One each was retired in 2017 and 2018, leaving 14 in service as of June 2022.

In October 1980, NATO formed its Airborne Early Warning and Control Force. The command controls NATO’s E-3 fleet and controlled the RAF E-3D force before its retirement. The aircraft fly out of forward operating sites in Greece, Italy, Norway and Turkey. NATO’s E-3s began flight operations in 1982.

The Force is managed by a group of sixteen NATO countries comprising the NAEW&C Programme Management Organization (NAPMO). As of 2022, the NAPMO members are Belgium, the Czech Republic, Denmark, Germany, Greece, Hungary, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Spain, Turkey and the United States. The UK was never a full NAPMO member but contributed its E-3Ds to the force. France is a NAPMO observer, and coordinates to maintain the interoperability of its E-3 fleet.

In December 2019, NAPMO signed a $1 billion contract with Boeing for a Final Lifetime Extension Program to bring the service life of the NAEW&C force to 2035.

Saudi Arabia

In 1981, Saudi Arabia signed a contract to acquire five E-3As and six KE-3 aerial refueling aircraft. The contract included an option for an additional four KE-3s, which was exercised in 1984. All aircraft were delivered by the end of 1987. Of the KE-3s, four were converted to RE-3As. Three of these later received the more extensive KE-3B upgrade. Another KE-3 was retired, leaving only five of these in service.

Starting in August 2001, Boeing applied mission computer upgrades to the Saudi E-3 fleet. The $60 million contract included related hardware and software changes and was completed in 2003. In September 2007, the Kingdom contracted for the installation of JTIDS terminals. The same year, it requested access to the RSIP upgrade – a contract was awarded in 2008.

From 2009, the fleet began receiving new MIDS/LVT sets, new crypto equipment and new radios. Finally, in 2019, a Foreign Military Sales (FMS) contract was awarded for UPX-40 sets for the fleet. While the Royal Saudi Air Force has not brought its fleet to the Block 40/45 standard outright, its aircraft now have many of its capabilities.

United Kingdom

In 1986, the UK released a solicitation for proposals for an AEW&C aircraft to fill the gap left by the imminent cancellation of the Nimrod AEW3 program. AEW3 would have been an AEW&C derivative of the Nimrod maritime patrol aircraft, with air search radars mounted to the nose and tail. By September 1986 the E-3 was the only remaining alternative to the Nimrod, and it was selected in December. Six were to be procured for the Royal Air Force (RAF), with the CFM56-2 engines. An option for a seventh was exercised in late 1987. The first aircraft was delivered in March 1991, with deliveries complete in May 1992. Britain’s E-3s were equipped with probes to support the probe and drogue refueling system used by its air force and with new radio equipment.

The UK’s 2021 Integrated Defence Review included a decision to retire the E-3D force ahead of the incoming Boeing E-7A Wedgetail, its replacement. Retirement of the aircraft by the end of 2021 created a capability gap, as the E-7 will not enter RAF service until 2023.

France

France ordered three E-3Fs in February 1987 in a similar configuration to the British aircraft. This includes the refueling probes and radio upgrades. Later that year the French government exercised an option for a fourth aircraft. The aircraft were delivered from May 1991 to February 1992.

In June 2022, only four E-3s are still operational. These four all received Block 40/45 upgrades starting in 2014 under a 2010 FMS contract, while the three remaining aircraft were retired.

Chile

Chile has signed a contract with the UK to procure three retired E-3Ds to replace the Chilean air force’s lone IAI Phalcon (known in Chile as the Cóndor). The Phalcon is a modified Boeing 707-385C. The E-3Ds are likely to enter service by the end of 2022.
