All British Aircraft Carriers (hunt for the Canadian ones) When the Suez crisis erupted, MAGNIFICENT had just completed landing stores for her successor, a more modern carrier whose construction had been suspended in 1946. The successor s name was to have been HMS Powerful, but the RCN decided to rename her BONAVENTURE after the bird sanctuary in the Gulf of St. Lawrence. Work on this ship had stopped three months after her launching in February, 1945, with the result that when construction resumed in 1952, improvements could be built into her. The most notable of these was the angled flight deck, which provided a longer landing run without sacrificing forward parking space, and permitted the removal of the unpopular crash barrier. Also noteworthy were a steam catapult and a mirror landing sight, the latter going far toward eliminating human error in landing.
The "Bonnie" was commissioned at Belfast on January 17, 1957, and arrived at Halifax on June 26, carrying on deck an experimental hydrofoil craft that was to serve in the development of HMCS Bras d’Or. Unlike her predecessors, BONAVENTURE had Banshee jet fighters and Tracker A/S aircraft as her complement. Like them, she enjoyed a busy career of flying training and participation in A/S and tactical exercises with ships of other NATO nations. What was expected to be her mid-life refit, carried out from 1966 to 1967, took 16 months and cost over $11 Million. This cost proved to be too high for Canada's Navy, as she was paid off in 1970, and sold for scrap.
All of this class carried 30 aircraft and had a maximum speed of 24 kts.
