RO.430 Airco De Havilland DH4 with Puma engine

Classic British WWI Two-seater

               '' Airco De Haviland DH.4 with Puma engine ''

In 1916 British aircraft designer Geoffrey de Havilland developed one such type in accordance with the "classic" layout. It was a two-seater biplane which history came to know by its official name, the D.H.4. At first, it was planned as a multipurpose airplane with the 230 h.p. Beardmore B.H.P. engine, however in the process of putting it into series production it transpired that the engine would have to be exchanged for another type, because the B.H.P. still needed perfecting and substantial revision. The D.H.4's active service career began in January 1917, and soon this type gained great renown among the pilots of the R.N.A.S. and the R.F.C.. It was capable of climbing quickly to a considerable altitude, and it could maneuver in combat with enemy airplanes. Its main task was to conduct daytime bombing missions over the territory of the enemy; however, occasionally the D.H.4 was used as a transport for secret service agents, and as a fighter and interceptor.During 1917 D.H.4s of various types, including those with Puma engines, were widely used in the skies of the Western Front, and even the arrival of the more modern D.H.9 did not end its career, because this successor appeared to be unsuccessful and was soon withdrawn from operations. And only the appearance of D.H.9A in 1918 pushed these machines into the background. They were gradually taken off from the front line, and passed on to training and patrol units. Many machines were sent to the British colonies, mainly to the Near East, to India and South Africa. There they were used until the mid 1920's, when they were exchanged for other types, mainly the Bristol F.2B Fighter
