About the Beagle B.121 Pup

The Beagle Pup is a British two-seat light aircraft that emerged in the late 1960s as one of the last products of the UK's once-thriving general aviation industry. Designed by Beagle Aircraft at Shoreham, the Pup was intended as a modern trainer and touring aircraft to compete with American designs like the Cessna 150 and Piper Cherokee. First flown in 1967, it featured a low-wing configuration, side-by-side seating, and a 100-horsepower Rolls-Royce Continental engine, offering docile handling characteristics ideal for ab-initio training.

The type earned a reputation for being well-built and pleasant to fly, with responsive controls and good visibility, though it never achieved the commercial success of its American rivals. Production ended in 1969 after Beagle's financial collapse, with only around 150 examples built across all variants (including the 150hp Pup 150 and 180hp Bulldog military trainer derivative). Today the Pup remains a cherished classic on the British register, prized by enthusiasts for its rarity and quintessentially British engineering.

Its operating envelope is typical of the era: never-exceed speed of 163 knots, cruise around 105 knots, and a stall speed of 43 knots in landing configuration. SkyMeter has tracked flights across airframes and operators, with routes observed.
