Q-ship

Along with and , ''Eagle'' was selected early to participate in a secret "Q-ship" program. The intention was to disguise the ship as a defenseless civilian vessel and, after luring an enemy submarine into close quarters on the surface, open fire with hidden guns and sink the unsuspecting

. For this reason, ''Eagle'' remained at Portsmouth, where she underwent further conversion into a Q-ship and received weapons and sonar gear. During this second conversion, the minesweeper was renamed ''Captor'' and redesignated PYc-40 on 18 April. With alterations complete on 19 May, the vessel reported for duty with the

. While at sea, the disguised Q-ship also helped cover the coastal convoy routes coming north from New York. As growing air and sea patrols had driven most U-boats away from the New England coast in May 1942, ''Captor'' had little chance to spot an enemy submarine and ended her wartime career without a single sighting. With the decline in the U-boat threat to the east coast of the United States late in the war, ''Captor'' was decommissioned at Boston on 4 October 1944.

She passed through several owners over the following decades while serving in this capacity. In 2005, she was acquired by R & J Shipping Inc and returned to her original name ''Harvard''. She went out of documentation in 2009, with her final fate unknown. As of 2005, no other ship in the United States Navy has been named ''Captor''.
