The Boulton Paul Balliol was a trainer designed in the late 1940's as a replacement for the RAF's aging North American Harvard trainers. 196 balliols were provided to the RAF and 30 navy "Sea Balliols" as pictured above fitted with arrester hooks and folding wings were supplied to the Royal Navy's FFA. The balliol was never made in the numbers hoped for by Boulton Paul, a direct result of the RAF's decision to use jet aircraft for it's future advanced trainers, the Balliol was retired as a military trainer from 1965 to 1957 in favour of , the de Havilland Vampire trainer, some of the Balliols were used by the fledgling Royal Ceylon Air Force with RAF guidance. It is of note that the second prototype Balliol was powered by the Armstrong Siddeley Mamba turboprop became the first ever single turboprop aircraft to fly on the 17th of May 1948.
