Handley Page 0/400

The Handley Page 0/400 was a British military aircraft designed in the 1930s as a heavy long-range bomber. Its name indicates a design specification: a payload of 400 pounds over a specified distance. It featured a large, four-engine biplane structure, with an emphasis on carrying significant weight for strategic missions. Although it was innovative for its time, it was quickly surpassed by more modern aircraft, limiting its operational use. The 0/400 played a role in the evolution of bomber design, illustrating the shift towards faster, more capable aircraft that would be used extensively in World War II.
