In 1932 Blackburn decided to build two prototypes of radial-engined Ripons, one powered by an Armstrong Siddeley Tiger and the second by a Bristol Pegasus, as a private venture (i.e. without an order from the Air Ministry). The Pegasus-engined prototype first flew on 30 September 1932, and after testing was chosen in preference to the Tiger-powered aircraft as a short-term replacement for the Ripon. A further 26 conversions of Ripons into Baffins were ordered in 1935 because of reliability problems associated with the Armstrong Siddeley Tiger engines powering Blackburn Sharks, and the desire to expand the strength of the Fleet Air Arm.
