3 Commando Brigade Air Squadron, Royal Marines, was formed in 1968 in Singapore by the amalgamation of three Commando Air Troops and the Brigade Flight. The squadron moved to Plymouth in 1971 and the two remaining UK Commando Air Troops became part of it. Apart from during the Falkands War, when the whole squadron was involved, it operated mostly on individual flight detachments. 3 Commando Brigade Air Squadron became 847 Naval Air Squadron in 1995.
