HMCS Bras d’Or: Imagining a Faster Warship
Her Majesty’s Canadian Ship (HMCS) Bras d’Or was developed by the Royal Canadian Navy (RCN) for testing anti-submarine warfare technology on an ocean-going hydrofoil. A high-speed vessel, it could operate like a conventional ship, with its hull floating in the water, or travel on its wing-like foils, with its hull completely out of the water, at speeds of up to 60 knots (110 kilometres per hour).
The RCN hydrofoil project had its origins in the innovative ideas of Alexander Graham Bell, who designed and tested a hydrofoil in 1919 on Bras d’Or Lake, in Cape Breton, Nova Scotia.
The testing of the full-sized craft, which was designed and built in Canada, began in 1968, proving the feasibility of its highly innovative concept. However, the program was cancelled in 1971, due to high costs and changing defence priorities. This model of the Bras d’Or was originally meant for use in a test tank, to evaluate the ship’s design and performance.
