No. 674 Squadron AAC

The number 674 was one of several allocated to the RAF AOP Squadrons during the second world war, however no squadron was commissioned before the numbers were transferred to the Army Air Corps in 1957. The number remained unused until the emergence of a distinct army and navy presence at the Defence Elementary Flying Training School necessitated restructuring into two separate squadrons. 674 Squadron was selected because it was the next available unused number.

A formation parade and ceremony was held at RAF Barkston Heath on 11 July 2003, with the Squadron stood up under the first Officer Commanding, Major A M Mills AAC. The squadron was inaugurated by Major General Richard Gerrard-Wright CB CBE DL on behalf of the Chief of the Defence Staff, General Sir Mike Walker. The Chief of the Defence Staff granted the squadron its own march, 'The Lincolnshire Poacher'.

Until April 2021 674 Sqn AAC was based at RAF Barkston Heath in Lincolnshire and latterly conducted Elementary Flying Training, operating the Slingsby Firefly in the 1990s through to around 2007, the Grob 115 Tutor from around 2007 until acquisition of the Prefect T1 turboprop trainer in the late 2010s. Students from all three Services of the Armed Forces were trained during this time as well as a limited number of students from overseas, mainly from certain Gulf States. Training was delivered as part of the UK Military Flying Training System (UKMFTS) contract.[1] The Squadron was temporarily stood down in April 2021 before reforming at Middle Wallop and a transition to the flying grading role.[2]
