Airco D.H.4

Rolls-Royce-Engined DH.4
The Airco D.H.4 was the first British plane designed specifically as a day-bomber. While it was originally designed for the 160hp Beardmore or 230hp BHP engine, but it is perhaps fortunate that the BHP production was delayed and the 250hp Rolls-Royce Eagle was available instead. The Eagle was an excellent engine and it only got better with successive marks, culminating with the 375hp Eagle VIII. Westland-built D.H.4s for the RNAS fitted twin Vickers guns for the pilot. When introduced the D.H.4 outperformed all other twin-seaters of its class and could outrun many enemy fighters. Its greatest weak spot was the long distance between the pilot and observer, making cooperation difficult, a fault that was corrected in the Airco D.H.9. DH4s served from March 1917 through to the Armistice, performing bombing, observation, photography, anti-Zeppelin, and anti-submarine duties. The D.H.4 was one of the great designs of World War One.

Liberty-Engined DH.4
After America's entry into the Great War, there were high hopes that the country's industrial might could be turned to aircraft manufacturing. Things never go as easily as expected, and the development of a two-seater based on the British DH4 with the 400hp Liberty engine faced repeated delays. After several delays to both the airframe and engine, Fisher, Standard, and Dayton-Wright built DH4s. While 1,213 were shipped to France, only 196 saw front-line combat.

Though the DH4 design had been already eclipsed by its first American use in July 1918, the US Air Service did not have alternatives. The DH4 holds the distinction of being the only fully American-built land warplane to see action in the war.
