HMCS Arnprior

There has been only one vessel named Arnprior in the Royal Canadian Navy.

HMCS Arnprior (K494)

Laid down as HMS Rising Castle, the Castle class corvette HMCS Arnprior was transferred to the Royal Canadian Navy and commissioned at Belfast, Northern Ireland, on June 8, 1944.

After work-ups at Tobermory, Scotland, she joined Escort Group C-1 at Londonderry, Northern Ireland, in August, leaving on August 19, to join her first convoy, ONM.249. HMCS Arnprior was continuously employed as an ocean escort for the balance of the war.

At the beginning of June 1945, she left Greenock, Scotland, for St. John’s, Newfoundland, where she underwent a 2-month refit, and from September was based at Halifax, Nova Scotia.

She was paid off in Halifax on March 14, 1946, and sold later that year to the Uruguayan Navy, which renamed her Montevideo and operated her as a training ship until 1975.
