Bonaventure the last Canadian Aircraft Carrier

HMCS Bonaventure

The aircraft carrier “HMCS Bonaventure” from 1957 to 1970 and was the third and the last aircraft carrier to serve Canada. It was Initially laid down for England as “HMS Powerful “as part of the second batch of the Colossus class ships ordered during the Second World War. The work was suspended in May 1946 following the end of the Second World War, and the hull was laid up incomplete at a Belfast Northern Ireland shipyard.

In 1952, the Royal Canadian Navy was looking to replace their existing aircraft carrier the ⇒HMCS Magnificent.  So on 23 April, the Canadian government authorized the expenditure of $21 million to acquire England’s  aircraft Carrier called the “Powerful”  “but remember it’s still just only a shell.”

At the time the Canada’s Royal Canadian Navy was in the market for an aircraft carrier and had the Powerful  offered to them by the British. They had also been offered a Hermes-class aircraft carrier by the United Kingdom but found it too costly and two Essex-class aircraft carriers on loan from the United States Navy, they were also were considered too costly.

The choice of the Powerful was made due to initial cost considerations as well as financial support for our common wealth partner, United Kingdom.

Agreement on the purchase of Powerful (Majestic class carrier) was reached on 29 November 1952s but was back-dated to 12 July. Work on the shell of the “Powerful” ( Bonaventure) resumed, this time to a modernized design incorporating recent carrier operation developments, such as the angled flight deck and steam catapults. The design changes cost a further $10 million. Other changes that were incorporated were American radar and armament. Construction was  completed on 17 January 1957, (5 years later) and the vessel was finally commissioned into the Royal Canadian Navy at Belfast, renamed Bonaventure with Captain H.V. Gross in command.

NOTE … Bonaventure was named after the  Bonaventure Island, a bird sanctuary in the Gulf of St. Lawrence

On March 1957, the aircraft carrier began sea trials in the English Channel and after completion, the Bonaventure sailed for Canada and docked at her home port in Halifax, Nova Scotia,  June 26 1957.

1964 Mid-life refit and ultimate fate.

In 1964, 7 years after purchasing the HMCS Bonaventure from the English government, Canadian Navy called for a mid life refit of Bonaventure in order to extend the aircraft carrier’s service. While the Canadian Naval Board already planned on the carrier’s upcoming refit.

They didn’t expect the numbers, the cost that was associated with the refit to rise out of control.

So beginning in April 1966, the carrier began a refit at Davie Shipbuilding in Lauzon Quebec. The initial estimate for the refit was $8 million. However, during the refit, numerous issues with the ship were found “which had been present since the initial construction.” With the added construction it led to cost overruns and delays. In the end, the refit took 18 months and cost $17 million and both behind schedule and well over budget. The refit was complete in August 1967

This aircraft carrier is only 10 years old. Life expectancy of an aircraft carrier 15-40 years

1970, 3 years after spending 17 million on a refit our Canadian military sought to cut spending in the armed forces and the Bonaventure was on their hit list.  Bonaventure was decommissioned at Halifax on 3 July 1970, and sold for disposal and bought by Tung Chen S Steel Company of Taiwan for scrap and broken up in 1971.

Now threw all fairness, I would think the operation cost on an aircraft carrier would be huge. Canada has not owned one since and as of posting have no intention of building one.
