Handley Page H.P.54 Harrow

The Handley Page H.P.54 Harrow was a British twin‑engine bomber and transport aircraft built by Handley Page in the mid‑1930s. Designed to meet Air Ministry Specification B.27/34 for a high‑speed, long‑range night bomber, the Harrow first flew on 19 May 1936 and entered service with RAF Bomber Command in 1937. Its all‑metal, low‑wing monoplane layout featured a semi‑monocoque fuselage, a pair of 1,050 hp Bristol Pegasus radial engines, and a retractable undercarriage, giving a top speed of about 265 mph and a range of 1,200 km. The crew of five operated defensive armament in a dorsal turret and a ventral gun position, while an internal bomb bay could hold up to 2,000 lb of ordnance. Although quickly eclipsed by more modern designs such as the Bristol Blenheim, the Harrow proved valuable as a transport and training platform, ferrying troops, equipment, and later serving as a night‑training aircraft. Its versatility helped the RAF transition from biplane bombers to all‑metal monoplanes and contributed to the development of later Handley Page aircraft, cementing its place in pre‑World War II aviation history. The surviving examples, though few, are preserved in museums, illustrating its role in the evolution of British air power.
