The 78th Fighter Group served with the Eighth Air Force from 1943 until the end of the war, supporting the campaign in north-western Europe and the advance into Germany.
The group was constituted as the 78th Pursuit Group (Interceptor) on 13 January 1942 and activated on 9 February 1942. It trained with the P-38, before moving to Britain in November-December 1942 to join the Eighth Air Force.
Early in the planning for Operation Torch the 78th and its aircraft were allocated as a general fighter reserve, to be held in Britain until needed. The group's pilots and aircraft were then moved to Africa after the existing units taking part in the invasion began to run short of P-38s, which had the range to operate over the long distances involved in the fighting.
After losing its P-38s, the group converted to the P-47 Thunderbolt.
On 8 April the group became officially operational. At first it was used to fly fighter sweeps over the Dutch and French coasts, mainly to give the pilots combat experience.
The group was used on a wide range of missions, including bomber escort, attacks on German airfields and transport links and troop concentrations.
Between 20-25 February 1944 the group took part in 'Big Week', a series of attacks on the Luftwaffe and the German aircraft industry. It was took part in the preparations for the D-Day landings, and supported the landings themselves. In July it took part in the breakout at St. Lo. In September the group took part in Operation Market Garden, and was awarded a Distinguished Unit Citation for escorting the bomber and troop carrier aircraft and attack German targets.
In December 1944 the group converted to the P-51 Mustang. In December 1944-January 1945 the group took part in the Battle of the Bulge. The group received a second DUC for destroying a large number of German aircraft during a series of attacks on five Luftwaffe bases near Prague and Pilsen on 16 April 1945.
The group returned to the US in October 1945 and was inactivated on 18 October.
