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.

Looking to discontinue the operation of diesel-electric boats, the British government offered to sell Ursula and her sister submarines to Canada in 1993. The offer was accepted in 1998.

Problems were discovered with the piping welds on all four submarines, which delayed the reactivation of Ursula and her three sisters. Ursula was handed over to the Canadian Forces on 21 February 2003, and commissioned as HMCS Corner Brook on 26 June 2003

During a refit in 2006, elevated levels of lead were detected aboard the submarine; they were believed to come from the lead-brick ballast blocks used aboard Corner Brook. Between October 2006 and January 2008, Corner Brook was active for only 81 days.
