The Beagle B.121 Pup is a 1960s British two-seat single-engined training and touring aircraft built by Beagle Aircraft Limited at Shoreham Airport.


The Pup was designed as a single-engined all-metal two-seat aerobatic aircraft or a four-seat touring aircraft. The prototype Pup (a Series 1 G-AVDF) first flew from Shoreham Airport on 8 April 1967. The second and third aircraft were Series 2 aircraft fitted with an enlarged rudder which became standard on all production aircraft.

Beagle Aircraft Ltd chose to build the Pup following a market survey which demonstrated a global requirement for a 2-4 seat training/touring aircraft to replace aging Tiger Moths and Pipers used by flying clubs .

The first delivery was to the Shoreham Flying School on 12 April 1968. The aircraft was popular and sold to flying clubs and private users worldwide. A Series 3 variant, a four-seater, was developed for the Iranian Civil Air Training Organisation. By 1969 production had increased at Shoreham to one Pup a day, aircraft were flown to either Rearsby Aerodrome or Cambridge Airport for painting and finishing. One aircraft was evaluated by the Royal New Zealand Air Force in 1969, but was not ordered. In December 1969 the government withdrew financial support for Beagle and the company was placed in receivership. Over 250 Pups were on order but production ceased with the 152nd aircraft.

A military version of the Pup was developed as the Beagle B.125 Bulldog with a 200 hp (150 kW) Lycoming engine. Only one prototype aircraft was built by Beagle before it ceased operations, the design and production was taken over by Scottish Aviation.
