caption_attribution_description: English: The nation's newest and most advanced attack submarine Seawolf (SSN 21) puts to sea in the Narragansett Bay operating area for her first at-sea trial operations on July 3, 1996. Sea trials include various tests of the Seawolf propulsion systems and the first underway submergence of the submarine. The Seawolf represents the Navy's most advanced quieting technology, weaponry, tactical capability and communications. Seawolf is scheduled to be delivered to the Navy and commissioned this fall.

context_page_description: The Seawolf class is a class of nuclear-powered fast attack submarines in service with the United States Navy. The class was the intended successor to the Los Angeles class, and design work began in 1983. A fleet of 29 submarines was to be built over a ten-year period, but that was reduced to 12 submarines. The end of the Cold War and budget constraints led to the cancellation of any further additions to the fleet in 1995, leaving the Seawolf class limited to just three boats. This, in turn, led to the design of the smaller Virginia class. The Seawolf class cost about $3 billion per unit, making it the most expensive SSN submarine and second most expensive submarine ever, after the French SSBN Triomphant class.
