Airco DH.3
The Airco DH.3 was a British bomber aircraft of the First World War. The DH.3 was designed in 1916 as a long-range day bomber by Geoffrey de Havilland, chief designer at the Aircraft Manufacturing Company. It was a large biplane with wide-span three-bay wings, slender fuselage, and a curved rudder. It was powered by two  Beardmore engines, mounted as pushers between the wings. In addition to tailskid landing gear, two wheels were placed under the nose to prevent it from tipping over on the nose. A second prototype, designated DH.3A, was built with more powerful  Beardmore engines, and the War Office placed a production order for 50. This order was cancelled before any could be completed, possibly because the climb rate was still far too low, with it taking 58 minutes to reach 6,500 feet, and the other contender, the Royal Aircraft Factory F.E.4 was even worse, which made strategic bombing with these machines impracticable. The two prototypes were scrapped in 1917. The DH.10 Amiens was developed from the DH.3A with much more powerful engines (boosting installed power from  to nearly ) and some detail changes were made. This development first flew in March 1918, but was too late to see squadron service during the war. Specifications (DH.3)
