"... the de Havilland machine has unquestionably proved itself superior to the Fokker in speed, manoeuvrability, climbing and general fighting efficiency."

Sir Henry Rawlinson - 23rd May 1916

The single-seat Airco DH2 was designed as a result of lessons learned in early aerial combat.  This was Geoffrey de Havilland's 2nd pusher design for the Aircraft Manufacturing Company (Airco) and probably one of the most significant.
It was derived from the Airco DH1 two-seater and retained the biplane pusher layout.  This afforded the pilot the maximum possible field of view from the forward-most tub. Significantly smaller and lighter than its predecessor, the Airco DH2 emphasised manoeuvrability as a primary design aim and it was soon adopted into Royal Flying Corps (RFC) service.
The type was unusual in adopting a fixed forward-firing .303 Lewis machine gun fitted in the nose of the aircraft which made it a significant leap forward in dog-fighting capability. The gun could be positioned in mid-air on either of the 3 flexible mounts although most pilots chose the forward-facing central position and opted for aiming the aircraft at the enemy rather than the gun.

The prototype (4372) was first flown in July 1915 and entered RFC service in February 1916 and the vast majority of the production aircraft were fitted with a Gnôme Monosoupape 100 hp rotary engine. 
During WW1 the Airco DH2 was flown by a number of notable pilots including Major Lance Hawker VC, who claimed 7 victories as Commander of No 24 Squadron RFC (Hawker was later shot down by ‘Red Baron’ Manfred von Richthofen). Additionally, Squadron Leader Lionel Rees won the Victoria Cross in an Airco DH2 for single handedly attacking a formation of 10 German aircraft on 1st July 1916.
The type saw major service on the Western Front and was heavily engaged during the Battle of the Somme with No.24 Squadron RFC, who destroyed 44 enemy machines during the conflict.

Despite being very manoeuvrable and easy to fly, a number of accident occurred during pilot training although this was attributed to the poor standard or airmen rather than any deficiencies in the aircraft. 
In total some 453 Airco DH2’s were built, all by Airco at their works in Hendon, although it was very quickly outclassed by the new German tractor biplane such as the Halberstad D.II and Albatross D.I, which appeared in the skies over France in 1916. 
The introduction of reliable interrupter gear allowing firing through the propeller disc resulted in the DH2 and similar types being superseded in the RFC by British tractor biplanes such as the Sopwith Camel and RAF SE5A and in 1917 No.24 Squadron had their Airco DH2’s replaced with Airco DH5’s.
A few aircraft remained active as trainers into 1918, but by the Armistice on 11th November there were no DH2's left in service with what by then had become the RAF.
