US Navy wants to purchase new TAGOS sonar reconnaissance ships for anti-submarine operations

14

According to a May 27, 2021 report by the US Congressional Research Service, the US Navy expects to acquire the first of its planned seven new class TAGOS (X) ocean observing ships in 2022.


According to preliminary calculations of the Navy, the ships will cost about $ 400 million each. The question now before the US Congress is whether to approve the entire program, reject it, or change the funding requests for the program.

The main task of the ships that the American fleet is going to purchase is reconnaissance and surveillance, primarily for the anti-submarine operations of the US Navy. This is especially true in the vastness of the World Ocean - both in the Indo-Pacific region and in the Atlantic, given the growing confrontation between the United States and China and Russia and the need for operations against submarines of a potential enemy.

The Navy's draft budget emphasizes that TAGOS ships will use the Surveillance Antenna Sensing System (SURTASS) to collect underwater acoustic data. Also, the ships will have electronic equipment for processing and transmitting data via satellite to coastal stations.

The program indicates that the ships will be under the control of the Military Command of Maritime Transportation, that is, they will be listed as auxiliary. This is evidenced by the decoding of the name: the letter T indicates the Military Command of Maritime Transportation, A indicates the auxiliary nature of the ships, the letter G means that they will have a common or different mission, and the combination of OS letters indicates the purpose of the mission - observing the ocean.


It is also worth noting that the US Navy is currently operating five TAGOS ships - four Victorious-class ships that entered service. fleet in 1991-1993, and one Impeccable-class ship entered service in 2000. By the end of 2020, all 5 ships were relocated to Yokohama in Japan

Four Victorious ships (T-AGOS-19-22) each have a displacement of 3400 tons and are capable of a speed of 16 knots. These ships usually carry 27 people, including 22 civilian specialists and 5 naval sailors. A distinctive feature of such ships is that they were the first ships built on the principle of catamarans, with a small area of ​​the operating waterline. This design provides greater stability of the ship in difficult hydrometeorological conditions.

The Impeccable type sonar reconnaissance ship (T-AGOS-23) has a displacement of 5370 tons, has a speed of 12 knots, and has a crew of 26 civilian specialists and 18 naval sailors. The ship tows an active low-frequency antenna array of underwater noise direction finding devices, which allows collecting and then processing primary acoustic information.

However, the problem with existing ships is their age: they become obsolete, and this is especially noticeable in the example of the equipment used. Indeed, for 20-30 years, technical progress has been more than obvious, and there is an urgent need to bring observation ships in line with modern requirements and challenges.

    This is after the incident when they lost the Russian submarine "Rostov-on-Don" in the Mediterranean and could not find it. wassat

      Quite possible. "Varshavyanka" was searched all over the Mediterranean, and this is not a joke - it has "calibers" on it. And if there are special warheads on the "caliber", then it's not at all funny.

      The purpose of creating narrowly targeted vessels is not entirely clear, despite the fact that as part of the US AUG, the escort has similar or more advanced equipment.
      Maybe they are proposed to be used as part of the AUG outside the main escort?

        can afford) it would not hurt us to rework and update the entire anti-submarine program, taking into account technologies))

          There is no dispute - they can allow, but is it always advisable?
          They also entangled the entire water area around them and potential opponents with hydroacoustic equipment installed at the bottom.
          Is there a lack of information or is your underwater equipment performing poorly? Have you decided to make sure that not a single "mouse" in the world's oceans rushes past them?

            Not all. PBA carriers are either SOSUS enhancement in dangerous directions, or long-range sonar detection where SOSUS is not.

        The purpose is not quite clear

        UFOs are going to search, not otherwise.

        It's simple - the Yankees are strengthening the PLO lines.
        These ships are the heirs of the ever-memorable Stallworths, a sort of "mobile SOSUS". Their task is the long-range detection of submarines and the issuance of information to the command post of the submarine in the theater. They have nothing to do with the AUG - the carriers of the PBA provide not the object, but the zonal PLO (if we use the analogy from the air defense).

        1. Ships of long-range H / A detection have nothing to do with AUG, well, unless they reveal the situation along the deployment route or in the area of ​​combat maneuvering. Their speed is 12-16uz, and AVMA moves at 20-24 when deploying. He's atomic!
        2. Ams are looking for a panacea for the Poseidon-type NPA, and at the same time for our Ash trees and Boriks, which are by no means quieter than the third-generation PLA ...
        What can an undetected APRK or PKK SN do in a war in time - do not bring the Almighty!
        Therefore, the Yankees are strengthening their borders, up to a 1000 mile zone, where stationary means of defense and anti-aircraft defense and mobile forces of anti-aircraft defense play the main role for them. So - the enemy senses where it will be hard for him, so he fusses in advance. But how! "Not everything for the cat is Shrovetide, there will be a great post." (from)
        AHA.

        the main thing is to write more and smarterly))))), already worked together, maybe Kaptsov split in two?
        because there is very little bad in opposition)

    Varshavyanka is good, but it seems that Rubin had a project for a small submarine with a vneu. There would be more like that. Schaub went to the Baltic and the Black Sea.

        So it seems like the bench prototype is working properly. But we go our own way and our system is different from competitors.
