On December 2 local time, the U.S. Navy signed a contract with general dynamics electric ship company (gdeb) to build nine Virginia class attack submarines for the U.S. Navy, with a total contract price of 22.2 billion US dollars.
The U.S. Navy ordered the latest type of Virginia attack submarine, bolckv, which will be equipped with new sonar equipment, defense news weekly reported Wednesday. The first ssn802 of the nine submarines ordered is already under construction, while the remaining eight that have not yet started construction will be improved, with the total length increasing from 114.9m to 140.2m, so as to carry the Virginia payload module (VPM), which can carry more Tomahawk cruise missiles.
CNN (CNN) pointed out that after loading the Virginia load module, the Virginia attack nuclear submarine block V can carry 40 Tomahawk cruise missiles, while the previous model can only carry 12 Tomahawk cruise missiles.
In addition to the significant increase in firepower, the block V-type displacement of Virginia class attack nuclear submarine has also increased from 7800 tons to 10200 tons, and it can also achieve self-sufficiency in the supply of water and oxygen, so that it can continue to sail under the water for several months.
Although the U.S. Navy ordered only nine Virginia class attack submarines this time, two less than this years budget, if the U.S. Navy purchased the tenth one, the unit price of the tenth one would be $2 billion, lower than the unit cost of the first nine, National Defense News Weekly reported.
Submarine forces are critical to the overall effectiveness and influence of the U.S. Navy. Acting U.S. Navy Secretary Thomas B. mordley said Tuesday that the U.S. Navy has fulfilled its commitment to enhance its combat effectiveness at home and below the surface with the rest of the world by ordering nine submarines.
Jack Reed, a member of the Senate Military Committee, stressed that the nine next-generation submarines would provide the Navy with unique national security advantages and unparalleled deterrence.
According to CNN, the Virginia class attack submarine ordered by the US Navy will be built at a shipyard in Rhode Island and is expected to be completed and delivered to the US Navy between 2025 and 2029. Virginia class attack submarines will gradually replace some of the Los Angeles class attack submarines currently in service in the U.S. Navy. Since 1976, Los Angeles class submarines have been in service in the U.S. Navy. At present, 27 of them have been decommissioned and another 35 are still in service.
According to the data, the first attack nuclear submarine of Virginia class entered the service of the US Navy in 2004. At present, there are 17 Virginia class ships serving in the US Navy, and another 11 are under construction. The Virginia block I to block IV in service is equipped with 12 vertical launch units and 4 533 mm torpedo, which can carry 12 Tomahawk cruise missiles and 25 mk48 torpedoes.
