Hart

The Hawker Hart was a biplane light bomber introduced by Hawker Aircraft in 1928 for the Royal Air Force. Developed from the earlier Hawker Horsley, the Hart incorporated a sleek, all‑metal fuselage and a powerful Rolls‑Royce Kestrel engine delivering 525 hp, which gave it a top speed of 185 mph—making it the fastest bomber in the world at the time of its entry into service. Its two‑seat configuration placed the pilot forward of the gunner/observer, and the aircraft featured a fixed, split‑type undercarriage, wooden wings with fabric covering, and a robust internal structure that tolerated a payload of up to 520 lb of bombs. The Hart’s excellent handling and high performance led to a prolific family of derivatives, including the Hawker Audax (army cooperation), the Hawker Demon (two‑seat fighter), and the Hawker Hind (improved bomber). Throughout the 1930s the type served in front‑line squadrons, overseas colonies, and training units, influencing British tactical doctrine by demonstrating the value of fast, versatile light bombers. Although it was quickly superseded by monoplane designs before World War II, the Hart’s legacy endured through its successful off‑shoots and its role in establishing Hawker as a premier aircraft manufacturer.
