The former HMS UNICORN was laid up by the Royal Navy in Oct 1994. She was accepted by Canada and named WINDSOR on 05 Jul 2001, and sailed from Faslane on 08 Oct 2001 to arrive in Halifax on 19 Oct 2001. Her training program in 2002 was interrupted on 28 Mar 2002 by what proved to be a minor flooding while submerged, but the extent of required repairs led to the decision to begin her conversion to Canadian standards Work Period early. During the course of this refit she was commissioned in Halifax on 04 Oct 2003. She returned to sea on 05 Apr 2004, and for the remainder of the year conducted trials and training exercises. In Jun 2005 WINDSOR commenced the first operational cycle for her class, lasting through Dec 2006. In this period she participated in a number of international exercises, including the successful tracking of a United States Navy nuclear-powered attack submarine and assisting in the work-ups of a USN carrier battle group. In Canadian waters, WINDSOR participated in the first-ever parachute rendezvous at sea practiced with Canada's Patrol Pathfinders (Canadian Army paratroopers), and also conducted several sovereignty patrols off the east coast for intelligence-gathering, surveillance and reconnaissance. WINDSOR entered an Extended Docking Work Period (EDWP) at the Fleet Maintenance Facility Cape Scott in Halifax on 15 Jan 2007, which was completed on 30 Nov 2012. In the ensuing operational cycle, WINDSOR has spent a total of 174 days at sea before being docked in Mar 2014 to repair a defective diesel generator.
