667 Squadron Royal Air Force formed up on 1 December 1943, at RAF Gosport as an anti-aircraft co-operation squadron for anti-aircraft training duties. For target-towing duties the aircraft used were the Defiant, Barracuda and Vengeance. For the gun-laying duties the Hurricane, Oxford and, later, the Spitfire were used. The Squadron's wartime role was somewhat unusual as they co-operated with Army and Navy batteries and ships in their sorties. 667 Sqn remained at RAF Gosport until disbandment on 22 December 1945.

The Squadron Reformed
The Squadron reformed as 667 Squadron Army Air Corps (AAC) on 1 September 1957, as the AAC Trials Section, based at Middle Wallop. The Squadron carried out initial trials on a variety of fixed wing and rotary aircraft and their associated equipment. In 1971 the Squadron moved to Netheravon and were augmented by 6 Flight, 14 Flight, 15 Flight and 132 Flight to form the new 667 Squadron Army Air Corps. The Squadron was under command of United Kingdom Land Forces and in 1973, due to the size of the Squadron, were upgraded to Regimental status and re-titled 7 Regiment Army Air Corps. The Squadron was again disbanded and later reformed as Demonstration and Trials Squadron under command of the Army Air Corps Centre. In 1987 it was renamed as Development and Trials (D&T) Squadron, under command of the Director Army Air Corps. On 1 April 1990 D&T Squadron became 667 (D&T) Squadron AAC. In October 2009, 667 (D&T) Sqn AAC became part of the Joint Helicopter Command Operational Evaluation Unit and came under operational command of the Rotary Wing Operational Evaluation and Tactics Unit and Support Helicopter Standards and Evaluation at Royal Air Force Benson, Oxfordshire. For administrative purposes the Squadron comes under control of Headquarters Army Air Corps.
