The Handley Page H.P.54 Harrow was a twin-engine, high-wing monoplane heavy bomber with a fixed undercarriage, designed by Handley Page for the Royal Air Force and flown in the Second World War mainly as a transport. It was the production version of the H.P.51, itself designed by Gustav Lachmann, and Air Ministry specification B.29/35 was written around it in 1935 as a stop-gap heavy bomber. It had variable-pitch propellers, hydraulically powered turrets and steam-heated cabins, but its performance could not match bombers such as the Armstrong Whitworth Whitley. After the first flight at Radlett on 10 October 1936, 100 were delivered to five bomber squadrons by the end of 1937, 19 as the Mk.I and 81 as the Mk.II. Withdrawn from bomber duty by the end of 1939 without flying a combat mission, Harrows served as transports and air ambulances, towed Long Aerial Mines in the Blitz, trialled refuelling Short Empire flying boats, and were retired in May 1945.
