Canadian Balao/Tench - class Submarines
Following WWII, the Royal Canadian Navy had an interest in re-establishing its submarine service and in the late 1950s, as an essential stopgap to further purchases, they sought a boat to train in. The United States Navy gave them a choice from among ten boats in the Reserve Fleet and USS
Burrfish was selected. An official agreement to loan a submarine to the Royal Canadian Navy for five years was finalized after approval by the Canadian Cabinet and ratification by the United States Congress in May 1960.
In the fall of 1960, the prospective crew was sent to New London, Connecticut for US submarine training. On 11 May 1961, USS
Burrfish was decommissioned and recommissioned into the Royal Canadian Navy at New London as HMCS
Grilse (SS-71), the second vessel to bear the name.
Having re-established the Canadian submarine service,
Grilse was acquired by the Royal Canadian Navy for use as a training vessel for anti-submarine warfare training on the Pacific coast; while more modern, newly acquired
Oberon- class submarines would serve on the Atlantic. However, the HMCS
Grilse lacked the speed of more modern subs and her sensor and weapons outfit were not up to the task of anti-submarine warfare. As a result,
Grilse spent most of her time serving as a mobile target for Canadian and American surface ships and aircraft.
In May 1966, her five-year loan was renewed for $1 million, and the sub underwent a refit in 1967 for $1.2 million. In 1968, the Canadian Navy, now called Maritime Command, was offered a more modern
Tench-class submarine by the US, and Maritime Command chose to accept the offer. Despite being recently refit and having three years left on her lease, the Canadian government was unwilling or unable to fund the operation of a second submarine for Canada's West Coast, thus
Grilse was left to languish alongside once her successor was selected.
The former USS
Argonaut, a
Tench-class submarine, was purchased by Canada outright for a cost of $153,000 and refit at an additional cost of $2.5 million.
Argonaut had received the Fleet Snorkel upgrades which included a snorkel system, streamlined sail, as well as a chin-mounted sonar. She was commissioned on 2 December 1968 as HMCS
Rainbow (SS-75). The modernization took eight months to complete and following its completion,
Rainbow took up the duties of the out-of-service
Grilse of performing anti-submarine warfare training on the West Coast.
With the arrival of the new HMCS
Rainbow,
Grilse never sailed again. Some of
Grilse's more modern gear was taken out and transferred to
Rainbow, however
Grilse had to remain operationally capable in accordance with the lease agreement and the transfer was limited. The sub returned to the US in September 1969.
HMCS
Grilse was struck from the Naval Register on 19 July 1969.
Grilse was officially paid off from Maritime Command on 2 October 1969 and returned to the US Navy the same day. She was sunk as a target off San Clemente Island, California, on 19 November 1969.
HMCS
Rainbow was decommissioned on 31 December 1974, after only six years, due to budget cuts and her need for a refit. Maritime Command kept the submarine in reserve, laid up until 1976, hoping to return her to service. However, in 1976, the boat was returned to the United States and scrapped at Portland, Oregon in 1977. After this, the story of Canadian submarines on the West Coast would come to a close for more than 30 years, until HMCS
Corner Brook, the first of two
Victoria - class submarines to be assigned to Maritime Forces Pacific (MARPAC), would be transferred to Esquimalt, BC in May 2011.
As always, comments and critique are much appreciated! Many thanks and much respect to Colosseum - 99% of the work is his, this is more or less a simple repaint and small modification on my part. Hopefully it's acceptable to post this here instead of creating a new thread.
