Sensors:

The USS Virginia Class Submarine SSN-774 is equipped with a range of advanced sensor systems that allow it to operate effectively in a variety of environments and perform a wide range of missions.

AN/BYG-1 Combat Control System: The AN/BYG-1 is a combat control system that integrates data from various sources, including sonar, radar, and other sensors. This system provides the submarine’s crew with a comprehensive situational awareness picture, allowing them to detect and track enemy vessels and submarines, and plan and execute complex mission profiles.
Sonar Systems: The submarine’s sonar systems include a spherical active and passive sonar array, a high-frequency sonar for shallow water operations, and a towed array sonar that can be deployed to provide greater detection range. These sonar systems allow the submarine to detect and track enemy vessels and submarines, and provide situational awareness in complex environments.
Imaging Systems: The submarine is equipped with a range of imaging systems, including a high-resolution camera system and an infrared imaging system, which can be used for navigation, situational awareness, and intelligence gathering.
Electronic Support Measures (ESM): The ESM system is designed to detect and identify radar and other electronic emissions from enemy vessels and aircraft, providing the submarine’s crew with early warning of potential threats.
Satellite Communications: The submarine is equipped with advanced satellite communication systems that allow it to maintain communication with the outside world and receive real-time intelligence and mission updates.

Armaments

The USS Virginia Class Submarine SSN-774 is equipped with a range of advanced armament systems that allow it to perform a variety of missions.

Torpedoes: The Virginia-class submarine is equipped with four 21-inch torpedo tubes, which can be used to launch a variety of torpedoes, including the Mark 48 advanced capability torpedo.
Tomahawk Cruise Missiles: The submarine is also equipped with 12 vertical launch system (VLS) tubes that can launch Tomahawk cruise missiles. The Tomahawk missile is a long-range, all-weather, subsonic cruise missile that is capable of attacking both land-based and sea-based targets.

USS Virginia Class Submarine vs Seawolf Class Submarines

The Virginia-class and Seawolf-class submarines are both fast attack submarines designed for a variety of mission areas, but there are some key differences between the two classes:

Cost: The Seawolf-class submarines were very expensive to build, with each boat costing around $3 billion in 1998 dollars. In contrast, the Virginia-class submarines are estimated to cost around $2.7 billion each.
Size and displacement: The Seawolf-class submarines are larger than the Virginia-class, with a displacement of around 9,000 tons compared to the Virginia-class’ displacement of around 7,800 tons. The Seawolf-class submarines are also longer, with a length of 353 feet compared to the Virginia-class’ length of 377 feet.
Speed: Both classes of the submarine are designed to be fast and agile, but the Seawolf-class submarines are faster, with a top speed of around 35 knots compared to the Virginia-class’ top speed of around 25 knots.
Armament: Both classes of a submarine are equipped with advanced armament systems, but the Seawolf-class submarines are capable of carrying more torpedoes and cruise missiles than the Virginia class. The Seawolf class also has a large lock-in/lock-out chamber for special forces operations.
Production: The Seawolf-class submarines were designed to replace the aging Los Angeles-class submarines, but only three were built due to their high cost. The Virginia class, on the other hand, was designed to be an affordable replacement for the Los Angeles class, and the Navy plans to build a total of 30 Virginia-class submarines.

In general, the Virginia-class submarines are a more cost-effective and versatile option, while the Seawolf-class submarines are larger and more heavily armed, but much more expensive.

How Many Virginia Class Submarines are There?

There are a total of 25 Virginia-class submarines that have been commissioned by the U.S. Navy. The program calls for a total of 51 submarines to be built, with production scheduled to continue until 2044.

What is The Cost of a Virginia Class Submarine?

The cost of a Virginia-class submarine varies depending on the specific boat and the year it was built. The most recent Block V Virginia-class submarines are estimated to cost around $3.7 billion per boat, while earlier boats in the class cost around $2.7 billion.
