History:
First flown in 1917 and served in various Squadrons on the Western Front until the end of World War 1. The performance of the DH9 was disappointing due to the Puma engine and a replacement aircraft known as the DH9A soon followed. This was the same as the DH9 but with a Rolls-Royce Eagle VIII or Liberty engine. Nevertheless 3,204 DH9 aircraft were built and they saw considerable action.

103 Squadron were equipped with the DH9 from December 1917 to the time they were disbanded in October 1919 and flew the aircraft with great distinction bombing enemy supply bases, airfields and communications behind the front line.
