Virginia-class cruiser
The ''Virginia''-class nuclear guided-missile cruisers, also known as the CGN-38 class, were a series of four double-ended (with missile armament carried both fore and aft) guided-missile cruisers commissioned in the late 1970s, which served in the United States Navy until the mid-to-late 1990s. With their nuclear power plants, and the resulting capability of steaming at high speeds for long periods of time, these were excellent escorts for the fast nuclear-powered aircraft carriers, such as the . Their main mission was as air-defense ships, though they did have excellent Flagship facilities, capabilities as anti-submarine (ASW) ships, surface-to-surface warfare (SSW) ships, and in gun and missile bombardment of shore targets.
The ships had a relatively short service life. They were so expensive to operate that it was determined that it was more effective to replace them with new conventionally powered ships, so they were decommissioned rather than put them through a refueling overhaul.
==Class description==
The ships were derived from the earlier ''California'' class nuclear cruiser (CGN-36 class). They were decommissioned as part of the early 1990s "peace dividend" after the Cold War ended. A fifth warship, the CGN-42, was canceled before being named or laid down. It was found that, while it was possible to mass-produce nuclear-powered warships, the ships were less cost-efficient than conventionally powered warships and the new gas-turbine-powered ships then entering the fleet -(the s) - required much less manpower. Following the end of production of this class, the U.S. Navy continued conventional destroyer/cruiser production, and it redesignated the DDG-47 class of guided missile destroyers as the CG-47 s. Three of the four ''Virginia''-class ships were authorized as guided missile frigates (in the pre-1975 definition), and they were redesignated as cruisers either before commissioning or before their launching. The last warship, USS ''Arkansas'', was authorized, laid down, launched, and commissioned as a guided-missile cruiser.
