![]() ![]() They are designed to be highly stealthy and capable of performing a wide range of missions, including anti-submarine warfare, surveillance, and special operations support. The Block V subs were confirmed to have an increased length, from 377 ft to 460 ft, and displacement, from 7,800 tons to 10,200 tons. The Virginia-class submarines are a class of nuclear-powered fast attack submarines developed by the United States Navy. Navy announced an order for nine new Virginia-class submarines – eight Block Vs and one Block IV – for a total contract price of $22 billion with an option for a tenth boat. Navy refers to this as 3:15.īlock IV will be followed by the Block V configuration which involves 10 boats and may incorporate the Virginia Payload Module (VPM), which would give guided-missile capability when the SSGNs are retired from service. ![]() Block IV RTOC efforts are intended to reduce planned availabilities by one to three and increase deployments to 15. Virginia class submarines do not have the traditional periscopes but Photonics Masts with color, black and white and infrared cameras. Navys future nuclear attack submarine, or SSN (X), is set to be notably wider than the services present Virginia class, bringing it more in line size-wise with its advanced Seawolf. The Block III submarines are built with two larger 87-inch diameter tubes able to house six TLAMS each.īlocks I-III Virginias are planned to undergo four depot maintenance availabilities and conduct 14 deployments. Hobby Boss does the best 688 kits in terms of scale, overall hull and sonar dome shape, masts and antennas, etc. The first 10 Block I and Block II Virginia-class submarines have 12 individual 21-inch diameter vertical launch tubes able to fire Tomahawk Land Attack Missiles (TLAMS). The Block V subs were confirmed to have an increased length, from 377 ft to 460 ft, and displacement, from 7,800 tons to 10,200 tons. The Block III submarines are fitted with the new Virginia Payload Tubes designed to lower costs and increase missile-firing payload possibilities. Navy announced an order for nine new Virginia-class submarines eight Block Vs and one Block IV for a total contract price of 22 billion with an option for a tenth boat. Here are a few of the differences: The Virginia hull form is based on the Seawolf hull and is noticeably different than the Los Angeles hull form (notably a blunter nose radius). USS Delaware (SSN 791), the last and final of eight Block III Virginia-class submarines, was commissioned in April 2020. Navy will increase the periodicity between depot maintenance availabilities and increase the number of deployments. By making these smaller-scale design changes to increase the component-level lifecycle of the submarine, the U.S. The Los Angeles class of submarines are nuclear-powered fast attack submarines ( SSN) in service with the United States Navy.
