HMCS Corner Brook

HMCS Corner Brook (SSK 878) is a long-range hunter-killer submarine (SSK) of the Royal Canadian Navy. She is the former Royal Navy Upholder-class submarine HMS Ursula (S42), purchased from the British at the end of the Cold War. She is the third boat of the Victoria class and is named after the city of Corner Brook, Newfoundland. The submarine was launched in 1989 and entered service with the Royal Navy in 1992. The Royal Navy laid Ursula up in 1994. In 1998, Canada acquired the submarine from the United Kingdom. The vessel entered service with the Canadian Armed Forces in 2003. Renamed Corner Brook, the submarine took part in several military exercises both internationally, such as NATO exercises and domestic, such as Operation Nanook. In June 2011, the submarine ran aground in Nootka Sound, damaging the vessel's bow. The submarine was sent for refit in 2014 to complete the repairs.
