The Gloster Gladiator was in operational service with 247 Squadron, stationed at RAF Roborough, Devon during the Battle of Britain. Although no combat sorties took place at the height of the aerial battles, 247 Squadron Gladiators intercepted a Heinkel He 111 in late October 1940, without result. 239 Squadron, using Gladiators for army cooperation and 804 Naval Air Squadron, outfitted with Sea Gladiators, were also operational during the Battle of Britain.[45]
