The U.S. Navy’s Seawolf-class submarine (Seawolf-class) is currently recognized as the world’s best performing nuclear-powered attack submarine, originally designed for the Soviet nuclear ballistic missile submarine during the Cold War, but only three were produced in the United States.
In 1980, the Soviet Union received information from the Walker Family of intelligence spies that the U.S. Navy could track its submarines through the noise generated by the spiral blades; therefore, the former Soviet Union continued to search for more advanced mechanical equipment to make more silent blades; in 1981, Toshiba Corporation of Japan sold the Soviet Union’s then nuclear-powered attack submarine through the Norwegian company Kongsberg. In 1981, Toshiba of Japan sold the Soviet Union’s most advanced milling machine (nine-axis CNC milling machine) through Kongsberg of Norway.
In the mid-1980s, the Soviet heart-shaped blades came into their own, the “steep drop in broadband acoustic noise profiles” generated by the new Akula-class nuclear submarines dropped dramatically, and the Akula-class The Akula-class submarines can operate at depths much higher than the U.S. Navy’s first-tier Los Angeles-class submarines, which can reach 2,000 feet (610 meters) compared to 650 feet for the Los Angeles-class submarines, immediately flipping the advantage for both sides.
“The Seawolf Class Submarine was built to fight the Soviets
To counter the threat of the Soviet Akula-class nuclear submarine, the U.S. Navy began developing the Seawolf-class nuclear attack submarine, which was designed with an alloy hull design of HY-100 steel plates, approximately 2 inches thick. pressure of seawater, operating immediately up to 2,000 feet, while the rupture depth is estimated to increase to between 2,400 and 3,000 feet.
The biggest advantage of the Seawolf-class submarine over the former Soviet Union or the present-day Russian submarines is not really in the weapons and missiles, but in the “superb silent capability,” “accurate and far-reaching sonar detection,” and “high-speed forward deployment. The biggest advantage of the submarine is not the weapon missiles, but the “superior silence”, “accurate and long-range sonar detection” and “high-speed forward deployment”. The first Seawolf-class submarine is a 7-foot shorter than the previous generation of submarine design, only 353 feet (108 meters), but the width has increased by 20% to 40 feet (12 meters), and the submarine displacement has increased to 12,158 tons.

The U.S. Navy has been working with the U.S. Department of Defense on the U.S.-Japan joint military exercise in the Pacific Ocean, and the U.S.S. Navy on the U.S.S. Seawolf-class submarine is powered by a Westinghouse S6W nuclear reactor, driving two steam turbines with a total power of 52,000 shaft horsepower, using jet pump propulsion and a surface speed of 18 knots and a maximum speed of 35 knots underwater. The maximum speed underwater is 35 knots, and the best silent speed is about 20 knots.
The Seawolf class is equipped with the BQQ-5D sonar system, which features a 24-foot diameter bow-mounted spherical active and passive array sonar, as well as a wide aperture passive outboard array sonar, and a modified TB-29A towed array sonar system with the BQS-24 sonar system for detecting mines or objects at close range.
The ship’s original combat system was the Lockheed Martin BSY-2, which used a network of 70 Motorola 68030 processors, the same processors used in early Macintosh computers, and has been replaced by the more advanced AN/ BYG-1 Weapons The USS Seawolf has been replaced by the more advanced AN/BYG-1 weapons control combat system.

Outside the spherical passive array sonar, an array of low-frequency passive sonar (three layers) is mounted. (Photo/reproduced from SlidePlayer/Undersea Warfare)
With eight torpedo tubes, it can carry up to 50 Mark 48 heavy torpedoes, submarine-launched harpoon anti-ship missiles and Tomahawk cruise missiles, some of which can also be replaced with mines.
