Description The Airco DH4 was a two-seat bomber with a clean, tractor layout and a non-rotary engine that improved handling and stability as the torque produced by in-line engines was nowhere near that of a rotary engine. It was the first bomber designed specifically for day light bombing. It first served in 1917 and was withdrawn from service in 1932. .
