uss seawolf submarine

Uss Seawolf Submarine - USS Seawolf (SSN-575), the world's second nuclear-powered submarine, was laid down on 7 September 1953 and commissioned on 30 March 1957 at the height of the Cold War. Until 1987, he performed exceptionally well. The world's first nuclear-powered submarine, the

But it was built with a very different nuclear power. There is a belief that Nautilus' strong stick was 'ordinary' and that his stick was just a test. In fact, two reactors were built at the same time: a pressurized water reactor (PWR) from Westinghouse and a sodium reactor from General Electric. Nautilus was the first to sport the sodium-fueled S2G submarine intermediate reactor (SIR). It is a liquid metal fast reactor (also called liquid metal fast reactor (LMFR)).

Superheaters used with steam must be powered, meaning they can only operate at 80% power. Although this proved adequate for the task (on 7 August 1958 she sank for a two-month voyage of 13,700 nm, unthinkable in a normal ship) it was decided that water pressure had a way to go, and so Seawolf was rebuilt. In 1958-60 what is now the S2Wa PWR.

She was designed as a power attack craft with six 21" (533 mm) torpedo tubes under the powerful BQR-4 passive sonar. Unlike the Nautilus she had a sunroof. Tall with a WW2 style coning tower. Although these ships are often described as similar. WW2 Ships Hull In terms of design, it was actually greatly simplified and modern at the time.

Designs of Seawolf and Nautilus - Despite their different histories above the water, the two ships are very similar and closely related.

USS Seawolf (left) and another famous special mission ship USS Halibut. Operation IVY BELLs was a complete secret at the time of the film and these two ships were noticed by very few who would have known their importance in the Cold War that was being played out at the time.

Seawolf served as an attack ship until 1971 when she entered dry dock at Mare Island Naval Shipyard to be converted into a 'Special Work Class', the term given to special intelligence subs. Its potential should be similar to that of the US halibut converted a few years ago. Unlike the Halibut, however, she lacked a gun and an extra compartment to house the computer so the foredeck of the sail was extended to accommodate the extra 'civilian' crew, sonar fish (sonar depth measurements with cameras towed under the boat). ) and propulsion. Room for saturation divers. As with the halibut, the horizontal bars were buried in the container but as a result its appearance was reduced. Submarine Development Group A ships are well kept secret with few pictures or plans showing their underwater modifications.

Since 1975, Seawolf has joined Halibut in conducting IVY BELL operations in the depths of the Okhotsk Sea off the Pacific coast of Russia. They were placed separately on Soviet communication cables in the remote nuclear submarine Petropavlovsk. Cable tubes of large equipment were laid by US Navy saturation divers while the ship was near the bottom.

Seawolf has many secrets, but there is no doubt that its crew and saturation divers produced groundbreaking and 'out of this world' secrets at the height of the Cold War. The Seawolf class is a nuclear powered class. - A powerful, fast attack submarine (SSN) in service with the United States Navy. The class replaced the Los Angeles class and operations began in 1983.

A fleet of 29 ships was to be built in two years, but was reduced to 12 ships. Due to the Cold War and budget constraints, any further additions to the fleet were canceled in 1995, leaving the Seawolf class limited to just three ships. This led to the formation of the small Virginia class. The Seawolf class cost about $3 billion per unit ($3.5 billion for the USS Jimmy Carter), making it the United States Navy's second largest submarine after the fast attack craft and Fracht Triumphant-class nuclear-powered submarines.

The Seawolf plan was designed to counter the threat of Soviet ballistic missile submarines such as the Typhoon class and attack submarines such as the Akula class in the deep sea. Seawolf-class hulls are made of HY-100 steel, which is stronger than the HY-80 steel used in previous classes, to withstand water pressure at greater depths.

Seawolf's ships are larger, faster, and quieter than Los Angeles' previous ships; They have more weapons and have twice as many torpedo tubes. These ships can carry up to 50 UGM-109 Tomahawk cruise missiles for land and sea attacks. Boats also have larger equipment to allow for shallower waters. The class uses the ARCI modified AN/BSY-2 commercial system, which includes a large circular sonar array, wide-angle (WAA) and a new tow-array zone.

However, as a result of their advanced design, the Seawolf-class submarines were more powerful. The estimated cost of 12 aircraft in this class was $33.6 billion, but construction of the three carriers was halted after the Cold War.

The USS Jimmy Carter is about 100 feet (30 m) longer than the other two ships in her class, thanks to the inclusion of a feature called a multi-mission platform (MMP) that enables underwater vehicles (ROV) launch and recovery. ) and Navy Seals.

The MMP can also be used as a subsea installation room for laying subsea fiber optic cables. This role was previously filled by the now decommissioned USS Parche. Jimmy Carter was replaced in this role by General Dynamics Electric Boat at a cost of $887 million. The Seawolf was designed as a faster, better-armed replacement for the nuclear-powered attack submarines of the Los Angeles Group.

The first class, Seawolf (SSN21), was ordered in January 1989 by the Electric Ship Division of General Dynamics, Connecticut, US, and commissioned in July 1997. Connecticut (SSN22) was commissioned in December 1998. The third, Jimmy Carter (SSN 23), was launched in June 2004 and commissioned in February 2005.

A third ship was modified to improve cargo handling and underwater maneuverability. Design changes included alterations to ballast control, space for mission control and the creation of a flexible connecting vessel known as the 'Wasp waist', which allowed installation and repair of cargo and the use of torpedo tubes.

The Seawolf was a product of the Cold War, designed to maintain the American advantage over Soviet submarines. With the end of the Cold War and the emphasis on maritime operations, the cost of the Seawolf fleet decreased, and the program aimed to make the new Virginia-class attack ships smaller and cheaper.

Seawolf's unique design represents refinement and innovation. It is more maneuverable than the Los Angeles class, space to upgrade and develop weapons, and improved sonar.

Seawolf is less than 9,137t (12,139t for Jimmy Carter) and 8,060t on the surface. A complete sound system was installed. It has a maximum dive speed of 35k and a 'calm' speed of 20k. It has a fleet of 116 employees including 15 officers. With a diving depth of 610m, it was designed with strong underwater and reusable bow jets.

The Battle Data System is a Lockheed Martin BSY-2 with a Network 70 68030 Motorola processor. The Raytheon AN/BYG-1 revolutionized warfare. Weapon control is controlled by a Raytheon Mk2 engine.

Similar to the Los Angeles class upgrade, the Seawolf has no external weapons. The ship is armed with Raytheon's land attack and anti-ship Tomahawk missiles. The Tomahawk ground attack range is 2,500 km.

The Tercom-Aided Inertial Navigation System (TAINS) guides the low-speed gun to the target at an altitude of 20m to 100m.

The Tomahawk can be equipped with a nuclear warhead, although it is typically not portable. Block III improvements include improved navigation and Navstar Global Positioning System (GPS) guidance. The anti-ship Tomahawk missile is equipped with temporal guidance and a powerful radar and anti-radiation warhead. The distance is up to 450 km.

The first underwater launch of the Raytheon Tactical Tomahawk Block IV missile took place in November 2002. Block IV includes a two-way satellite link that allows the missile to be repositioned in flight and provides imagery. Battle Damage (BDI). The gun entered service with USN ships in September 2004.

The Seawolf class also carries the Harpoon anti-ship missile from Boeing. The sub-harpoon uses radar to deliver a 225 kg warhead. The distance is 130 km and the speed is more than subsonic.
