The SURTASS Ships and a Tango (Red Storm Rising)

This is the latest installment of my "Red Storm Rising" posts.  In this segment I will be mentioning the SURTASS ships and one of the Submarines used by the Soviet Navy.  First off in the book, it was talked about the USNS Prevail, she was built along the lines of a tuna boat, but instead of a net for fish, the Prevail and her sisters hunted submarines, they would string behind them about 6000 ft of line and this would be her "tail", and the tail would detect submarines very far away when she would then notify Norfolk where the submarines were.  The Soviets knew about these boats,l but every time they approached one of these ships, they were vigorously prosecuted by an Orion.  Her crew were half civilian employed by the NSA and the other half were manned by the NAVY.   The only weapon on her was an M-14 against sharks.  She and her sisters were considered the most dangerous ASW platform that the United States had against the Soviet Submarines.  They would make tracks across the atlantic and detect all underwater emissions, from signals from U.S. Submarines to the propeller noises from Soviet Submarines, all submarines had a different "cavitation" noise based on powerplant type, propeller type and all submarines had their "quirks" that made Identifying them easier.

Stalwart-class auxiliary general ocean surveillance ships (T-AGOS) were a class of United States Naval Ship (USNS) auxiliary support Ocean Surveillance Ships commissioned between April 1984 and January 1990. Their original purpose was to collect underwater acoustical information using the Surveillance Towed Array Sensor System (SURTASS), a towed array passive sonar.

SURTASS began as development program in 1973 using the new research vessel Moana Wave. In 1980 SURTASS passed OPEVAL. The new Stalwart-class ocean surveillance ships had the first contract awarded on 26 September 1980 and were similar to the prototype ship, the Moana Wave. Initially the SURTASS system were passive, receive only sonar systems. The array was towed miles behind the ships and were designed for long range detection of submarines.
As the passive systems were being deployed, an active adjunct known as the SURTASS Low Frequency Active (LFA) systems was designed for long range detection. The active system must be used in conjunction with the passive received system. The active component transmits an audio signal between 100 Hz and 500 Hz from an array suspended below the ship while the passive SURTASS array is towed miles behind to receive the signal after it had reflected off the submarine. The active LFA system is an updated version of the fixed low frequency surveillance system known as Project Artemis.

Ocean surveillance ships have a single mission to gather underwater acoustical data. The T-AGOS ships operate to support the anti-submarine warfare mission of the Commanders in chief of the Atlantic and Pacific Fleets. The ships are operated and maintained by civilian contractors.
During the Cold War, ocean surveillance ships prowled the world's oceans searching for Soviet Navy submarines. Today, with the Cold War having thawed and the Soviet Union dismantled, these ships, operated by the Military Sea-lift Command and designated T-AGOS, now gather underwater acoustical data in support of U.S. Navy tactical operations in littoral waters. Their data is collected using the Surveillance Towed Array Sensor System (SURTASS) comprised of listening devices and electronic equipment that transmit the acoustic data via satellite to shore for analysis.
The ships first went to sea in the early 1980's, prowling the world's oceans in search of nuclear powered submarines belonging to the former Soviet Union. The SURTASS ships, with the hull designation T-AGOS, provided the world wide ocean surveillance, the US Navy required, with remarkable reliability. Today, they still patrol the vast oceans and also support fleet battle groups operating in littoral regions with the mission to gather underwater acoustical data. The T-AGOS ships operate in support of the anti-submarine warfare mission of the Commanders in chief of the Atlantic and Pacific Fleets.

SURTASS LFA is a long-range, all-weather, sonar system with both passive and active components, operating in the low frequency (LF) band (100–500 hertz [Hz]). USNS Impeccable has the original LFA system, weighing 155 tonnes; the 64-tonne Compact LFA derivative was developed for the smaller Victorious class. CLFA was installed on Able in 2008, on Effective in 2011 and Victorious in 2012; no further installations are planned.
The active system component, LFA, is an adjunct to the passive detection system, SURTASS, and is planned for use when passive system performance proves inadequate. LFA is a set of acoustic transmitting source elements suspended by cable from underneath a ship. These elements, called projectors, are devices that produce the active sound pulse, or ping. The projectors transform electrical energy to mechanical energy that set up vibrations or pressure disturbances within the water to produce a ping.
The characteristics and operating features of LFA are:

• The source is a vertical line array (VLA) of up to 18 source projectors suspended below the vessel. LFA’s transmitted sonar beam is omnidirectional (i.e., a full 360 degrees) in the horizontal (nominal depth of the LFA array center is 120 m [400 ft]), with a narrow vertical beamwidth that can be steered above or below the horizontal.
• The source frequency is between 100 and 500 Hz (the LFA system’s physical design does not allow for transmissions below 100 Hz). A variety of signal types can be used, including continuous wave (CW) and frequency-modulated (FM) signals. Signal bandwidth is approximately 30 Hz.
• The source level (SL) of an individual source projector is approximately 215 decibels (dB).
• The typical LFA transmitted sonar signal is not a constant tone, but a transmission of various waveforms that vary in frequency and duration. A complete sequence of transmissions is referred to as a ping and lasts from 6 to 100 seconds, although the duration of each continuous frequency transmission is never longer than 10 seconds.
• Duty cycles (ratio of sound “on” time to total time) are less than 20 percent—20 percent is the maximum physical limit of the LFA system. Typical duty cycles are approximately 7.5 to 10 percent.
• The time between pings is typically from 6 to 15 minutes.

The passive, or listening, part of the system is SURTASS, which detects returning echoes from submerged objects, such as submarines, through the use of hydrophones. These devices transform mechanical energy (received acoustic sound wave) to an electrical signal that can be analyzed by the signal processing system of the sonar. The SURTASS hydrophones are mounted on a horizontal receive array that is towed behind the vessel. The array length is 1,500 m (4,900 ft) with an operational depth of 150 to 460 m (500 to 1,500 ft). The SURTASS LFA ship must maintain a minimum speed of approximately 6 kilometers per hour (3.2 knots) through the water in order to tow the hydrophone array in the horizontal plane. The return signals or echoes, which are usually below background or ambient noise level, are then processed and evaluated to identify and classify potential underwater targets.

T-AGOS ships are operated by the Military Sealift Command and are under the administrative command of Commander, Undersea Surveillance. They are deployed under the Operational Control (OPCON) of the Theater ASW Commanders, CTF 84 and CTF 12. Civilian technicians who operate and maintain the mission equipment man the SURTASS Operations Center (SOC), the nerve center of the ship. When operating with tactical forces, military detachments are embarked for on-board analysis and direct reporting to fleet units. A SURTASS mission consists of 60 days on station while towing an array of hydrophones that collect acoustic data.

The ships are homeported at Little Creek and Saint Helena's Annex, Virginia; Anacortes, Washington; and Port Hueneme, California. When operating independently as in a deep ocean surveillance mission, acoustic data is transmitted to shore via satellite for analysis and reporting. SURTASS ships have proudly operated throughout the world supporting the Undersea Warfare/Anti-Submarine-Warfare mission of all five numbered fleets of the U.S. Navy.
The ship is designed to tow an array of underwater listening devices to collect acoustical data. The ship also carries electronic equipment to process and transmit that data via satellite to shore stations for evaluation. The ship, the listening devices and electronic equipment are all part of a system called the Surveillance Towed Array System, or SURTASS. SURTASS is a linear array of 8575 ft deployed on a 6000 ft tow cable and neutrally buoyant. The array can operate at depths between 500 and 1500 ft. Information from the array is relayed via WSC-6 (SHF) SATCOM link to shore. SURTASS patrols are of 60-90 days duration [which even with passive tank stabilization is a long time to wallow around at 3 kts].

The Monohull T-AGOS design, is based on the T-ATF Fleet Tug hull configuration. Various design features are incorporated to satisfy the SURTASS operating requirements and mission profile. The design is based on a mission duration of up to 90 days of towing operation at 3 knots, with a maximum sustained speed in transit of 11 knots. The ship's complement of 30 includes the SURTASS technical personnel, known as the (shipboard Operation and Maintenance (O&M) crew). In mission operations a total of 24 shipboard personnel, 18 ship's crew and 5 SURTASS O&M crew, is typical.
This program was completed after several rocky years stemming from the financial difficulties of Tacoma Boatbuilding Co. which built the first eight ships but initially was unable to complete T-AGOS 9-12 before filing for bankruptcy. Halter Marine built T-AGOS 13-18. The STALWART class T-AGOS vessels, T-AGOS 1 through T-AGOS 18, were originally ad-measured as less than 1600 gross tons and later re-admeasured as over 1600 gross tons.

The USNS BOLD (T-AGOS 12), the 12th ship of the Stalwart class, completed the 500th SURTASS mission, and a ceremony commemorating the milestone mission was conducted at U. S. Naval Station; Rota, Spain July 12, 2000 as BOLD made a portcall there following her historic patrol. Five hundred missions equate to over four million nautical miles of at-sea surveillance operations. Notable events included exchange of photo taking and greetings with helicopters, fixed wing aircraft and intelligence gathering vessels of the Soviet Union, at sea Medical Evacuations (MEDEVACS) for seriously ill or injured SURTASS ship crew members, sharks attacking the acoustic array, various periscope sightings, and iceberg evasion. Based on the number of BZ (Navy abbreviation for Well Done) messages received over the years, T-AGOS ships have time and time again proven their value both as strategic and tactical assets.

The SURTASS/Twin-Line Array Engineering Development Model was installed on the USNS Assertive (T-AGOS-9), and the first production model was installed on the USNS Bold (T- AGOS-12). Funding for six additional twin-line arrays was provided in the FY 2000 FYDP.
The Space and Naval Warfare Systems Command (SPAWAR), San Diego, manages the SURTASS program and contracts with the Raytheon Compny to operate and maintain the SURTASS equipment on T-AGOS ships. By early 1999 SPAWAR was inserting the second generation of commercial-off-the-shelf (COTS) equipment into the SURTASS baseline. USNS BOLD became the first T-AGOS ship to complete this upgrade, which added a Twin-Line towed array, a surface ship tracking capability, and included a COTS processing refresh and communications upgrade. The upgrades will significantly enhance the ships and SURTASS anti-submarine warfare capabilities in the high surface clutter environments of shallow water operations.
When deployed with a military detachment that augments its predominantly civilian crew for on-board analysis and direct contact reporting, the ships provide the fleet with a highly effective ocean surveillance capability that supports both deep ocean and shallow water warfare missions.



In the Book, the submarines that were called "Tango's, they were difficult to detect, you needed a good team from the ship and the helicopter to get them.  The Tango's were mentioned almost as much as the Victor class submarines.  

The Tango class was the NATO reporting name of a class of diesel-electric submarines that were built in the Soviet Union to replace the Foxtrot-class submarines assigned to the Black Sea and Northern Fleets. The Soviet designation of this class was Project 641B and it was also known as the Som (Catfish) class. The first of the class was completed in 1972 at Gorky. A total of 18 were built in two slightly different versions. The later type was several meters longer than the first, possibly because of the installation of ASW missile equipment.
The bow sonar installations appear to be similar to those fitted to Soviet nuclear attack submarines. The propulsion plant was the same as the last subgroup of the Foxtrot class. The Tango class had far more battery capacity, far higher than any previous conventional submarine class in the Soviet Navy; as a result, pressure hull volume increased. This allowed an underwater endurance in excess of a week before snorkeling was required.

Coupled with new armament and sensor fit, the Tango class were ideal for ambush operations against Western nuclear submarines at natural chokepoints.
Because of its all-hull rubber coating, the sub class was nicknamed "rezinka" [rubber]
Construction of this class has now stopped. One unit remains in the Black Sea Fleet but it may have been decommissioned since 2010.

Some more musings on the election in the 6th district.

The pundits here in Atlanta are still talking about the 6th district race, apparently the complaint was that there was too much rain to the media pundits especially on MSNBC,

I saw postings of the SJW's crying after the results were announced...The democrats have now been pushing a narrative that Ossoff wasn't left enough and they are pushing to go farther left.  They also are going full identity politics stating that Ossoff lost because he was white and that the democrats should have run a person of color or a female.   I am amazed that they ate doubling down on stupid and I hear that they are blaming Nancy Pelosi for the loss,  
    
  This article I cribbed off Resurgent, I though it brought some good points.

In 2016, Rodney Stooksbury got 38.3% of the vote in Georgia’s sixth congressional district after spending only around $1000.00. Less than a year later, Democrats spent $30million to get only ten percent more of the vote and still lose.
There are some real issues here that the cheering and moralizing will overlook. Democrats will say it should not have been so close, but Republicans can counter than outspending the GOP and still losing is a big deal. It is. The Democrats can note that the GOP was winning this district by twenty points regularly and now are barely winning. That is true too.
But there are some fundamental problems for Democrats that they are going to overlook as they declare moral victory.
First, the national netroots rallied to Jon Ossoff, who was completely unknown to the sixth congressional district. There was a state senator from within the district who had a built in constituency that crossed party lines. But that guy got rejected for this unknown who lived out of the district.
Second, Ossoff did live out of the district and that cost him a number of votes. Democrats want you to believe this race was about healthcare and a referendum on Trump. The reality is more voters talked about Ossoff being a carpetbagger than they talked about where either candidate stood on the issues.
Third, Democrats got cocky. In the last two weeks of the race they started knocking on Republican doors to try to turn out the vote. Yes, they needed to persuade persuadable Republicans to vote Ossoff, but they did not just target those voters. They blanketed the district, knocking on the doors of Trump voters. They saturated the district with robocalls. They overbought television advertisements. They overexposed their candidate.

Fourth, Ossoff never defined himself. He went negative on Handel, who had won this district in three elections and who was known by 90% of the district. He could not define a woman who everyone already knew and mostly liked. But no one knew Ossoff and he got defined as a Pelosi loving carpetbagger.
That leads me to the fifth point, Nancy Pelosi is as much an anchor on the Democrats as Trump is on the GOP, if not more so. If Democrats want to win GOP seats, Pelosi needs to stay in the shadows.
Sixth, Ossoff was way overexposed. People got tired of his ads. They were on constantly. They never changed. People tuned them out over time. He never shook up the advertisements or rolled out new attacks or positive messages. Democrats saying this was about healthcare want to focus on his literally last two days where he talked about healthcare. He otherwise did not go deep on policy on the campaign trail.
Seventh, this was a Republican district that was won by a well known and liked Republican who was able to offset poor fundraising with high name ID and likability. Trump voters turned out for her and got her across the finish line.
Eighth, and this is the most important point, Ossoff ran as a moderate Republican. He never attacked the President and opposed universal healthcare. But the national noise about this campaign filtered in. Local voters and local news coverage knew the national progressive activists viewed an Ossoff win as another step towards the impeachment of President Trump. By being so vocal about the implications of this race, the Democrats fired up the GOP voters to defend Trump. It is a poor strategy moving forward for them. This is a district they need and they lost it.
Ninth, despite the rhetoric, you should know that this was one of the most civil races I have witnessed. Yes, there were crazies and bad things happened to both sides, but largely the candidates and campaigns were very civil to each other and the attacks were relatively mild.
Tenth, expect Karen Handel to be her own person in Congress. She will stand up to both sides and she will not be a yes woman for anyone. Jon Ossoff too will come out of this with an enhanced reputation among Democrats. He is going to be a force to contend with in the future. His political career is just starting.

It is OVER!!

Look at the excited faces at CNN when they announced

the results of the special election.....I think they and the AJC will

be on suicide watch.

    Well after the Democrats dumped about 30 million dollars into this special election
and were trying to turn this into a referendum on the Trump presidency and were touting
"Jon Ossoff" whom didn't even live in the district but ran and somehow he was on the ballot
I guess residency rules don't apply I guess.  But anyhow after listening to the orgasmic job from
CNN, MSNBC and of course the local paper, the AJC  whom described Jon Ossoff in reverent
tones and that he would put a stick in the bicycle tires of the Trump administration.  He was
touted as the "Trump Killer" to the base to get them inflamed and out in force to get Ossoff
elected.  I was amazed at the lack of knowledge of the democrats and the editors at the AJC
when I told them that Ossoff will be a very junior congress critter and totally beholding to
Pelosi and Schumer for any committee spots.  He will be an extension of their policies and
will lose the 2018 election once the 6th district figures it out.   But Karen Handel did win
but I am still concerned that if the GOP don't get their act together the Democrats will pick up
seats in 2018.

Pithy musings...

I am working on my next installment of the Red Storm Rising post and here in GA we have the 6th congressional race going on, the voting is today.   The Congressman that had the office took a position with the Trump administration.  We have had 2 people running, one is a regular fixture of Georgia politics and her name is Karen Handel and she is a staunch Republican and the Democrats are running a guy named "Jon Ossoff", The money spent on this race is about 20 million dollars.  and 95% of Ossoff funding comes from out of state.  The democrats have been touting him to their base as a "Trump Killer"and a moderate who will work with the GOP, I laugh if he gets elected, he ain't going to do anything but suck up to the house leadership because he has to depend on Pelosi and Schumer for positions on any committee's because he is a junior congresscritter.   The total lack of knowledge displayed by the democrats and the editorials from the Atlanta Journal/Constitution speak of this guy in orgasmic tones I just shake my head at the total lack of civic knowledge.  The good thing is that after today the adds touting both candidates and denigrating the other will stop.

Monday Music "Knock on wood" by Amii Stewart

I am going back to the 70's, I shock people when I say that I like Disco. I always liked the beat, the flashy lights and it was a good way to end what I called the "Gutter Decade", the ending of Nanny State 1.0 A.K.A. Jimmy Carter's administration.

Amy Paulette "Amii" Stewart (born January 29, 1956) is an American disco/soul/dance-pop singer most famous for her hit disco record cover of Eddie Floyd's "Knock on Wood". Stewart is the stepsister of actress-singer Miquel Brown and aunt to Brown's actress-singer daughter Sinitta.

Amy Stewart was born 9th out of 11 children. Her father, Joseph Stewart II, signed her up for singing and dancing lessons in 1960, when she was four. There already was an Amy Stewart registered with Actor's Equity, so she changed the spelling of her name to Amii. She began attending Howard University in Washington but soon left to work with the D.C. Repertory Dance Company, studying ballet and modern dance. Before being signed to Ariola Records, Stewart was in the touring company of the stage production Bubbling Brown Sugar in 1975, firstly in Miami, then Broadway, and eventually London's West End, where she met Barry Leng, a record producer for Hansa records.
At the end of 1977, "You Really Touched My Heart" a Leng/Simon May composition, produced by Leng, was Stewart's first recording. An album followed, which contained five Leng/May songs, one Leng/Morris song and three cover versions.
Her first single, a disco cover version of the 1966 Eddie Floyd hit "Knock on Wood" (Floyd/Cropper), reached number one in the U.S. in April 1979, and earned her a platinum record and a Grammy Award nomination. It also reached number 6 in the UK, and number 2 in Australia. In the same year,

The original Knock on Wood album in its entirety remains officially unreleased on compact disc, a semi-official release was issued in Russia in 1999 on AS4000. This release paired this album with the follow-up release Paradise Bird and one bonus track "My Guy, My Girl", and includes all original artwork.
The album was released as simply Amii Stewart in the UK.
