12/5/2023 0 Comments Uss seawolf class submarineThe nuclear-powered Seawolf has a GE PWR S6W reactor system, two turbines rated 52,000hp (38.8MW), a pumpjet propulsor, a single shaft and one secondary propulsion submerged motor. The Seawolf submarines were upgraded with the Lockheed Martin AN/BQQ-10(V4) sonar processing system under the acoustic-rapid commercial-off-the-shelf insertion (A-RCI) programme.īPS 16 radar, operating at I band, is fitted for navigation. The submarine’s sonar suite is the BQQ 5D with bow-mounted active / passive arrays and wide aperture passive flank arrays.Īlso fitted are TB-16 surveillance and TB-29 tactical towed arrays, which will be replaced by the TB-29A thin-line towed array being developed by Lockheed Martin and BQS 24 active sonar for close-range detection. CountermeasuresĬountermeasures include the Northrop Grumman WLY-1 torpedo decoy system and a GTE WLQ-4(V)1 electronic countermeasure (ECM) system. The range is 50km (active) and 38km (passive). Seawolf was projected to be the most expensive ever built, with a total program cost for 12 submarines estimated in. It is capable of operating with or without wire guidance and uses both active and passive homing. Seawolf (SSN 21) was commissioned on 19 July 1997 at Electric Boat Shipyard. The Gould mk48 ADCAP torpedoes combat both high-performance surface ships and fast deep-diving submarines. Seawolf has eight 660mm torpedo tubes for launching torpedoes and missiles. The range is 130km and the speed is high subsonic. Sub-harpoon uses active radar homing to deliver a 225kg warhead. The Seawolf Class also carries the Harpoon anti-ship missile from Boeing. The missile entered service with USN surface ships in September 2004. Block IV includes a two-way satellite link that allows reprogramming of the missile in flight and transmission of battle damage indication (BDI) imagery. The first underwater launch of the new Raytheon Tactical Tomahawk block IV missile took place in November 2002. The anti-ship Tomahawk missile is equipped with inertial guidance and an active radar and anti-radiation homing head. Block III improvements include an improved propulsion system and Navstar global positioning system (GPS) guidance capability. Tomahawk can be fitted with a nuclear warhead, although it is not normally carried. The land-attack Tomahawk has a range of 2,500km.Ī Tercom-aided inertial navigation system (TAINS) guides the missile towards the target, flying at subsonic speed at an altitude of 20m to 100m. It was intended to replace the Los Angeles class, with design work starting in. The submarine is armed with both the land-attack and anti-ship version of the Tomahawk missile from Raytheon. The Seawolf class is a type of nuclear-powered submarine used by the US Navy. USS Seawolf and USS Connecticut each reportedly cost around 3 billion to produce, while the price tag for the improved USS Jimmy Carter was 3.5 billion making them the most expensive SSN submarines constructed and the second most expensive submarine ever to be built after the French SSBN Triomphant-class. Similarly to the improved Los Angeles Class, the Seawolf does not have any external weapons.
