HMCS Ojibwa, the first--and last--of her line.

 HMCS Ojibwa was the first of Canada's O-boats, built as all three of them were in Her Majesty's Dockyard in Chatham, England. OJ was launched in 1964, commissioned on 23 September 1965, and served in the Royal Canadian Navy for 33 years. Rescued in the nick of time from the breakers' yard, she was towed to Port Burwell, Ontario, where she is slated to be the star attraction in that town's naval museum.

Normally operating with a crew of 68, the Ojibwa set a sterling example for her sisters to follow. She spent most of her operational life in the Atlantic, with two brief deployments to the RCN's Pacific Command.
