In this February 2007 handout file photo provided by the US Navy, the research submarine NR-1 is towed away from U.S. Naval submarine base, in New London, Conn. The nuclear-powered NR-1, launched in Groton in 1969, was one of the most secretive vessels in the U.S. undersea force. It was taken out of service in 2008 and disassembled, its reactor disposed of. Now the Navy has collected pieces of it for an exhibit at a submarine museum in Groton, where it was based for the duration of its service life.
