752 Naval Air Squadron (752 NAS) was a Naval Air Squadron of the Royal Navy's Fleet Air Arm. Formed in May 1939, at RNAS Ford (HMS Peregrine) as an Observer Training Squadron, it was active through to 1945 as part of No. 1 Observer School. Ford was attacked in August 1940 and the squadron moved to RNAS Lee-on-Solent (HMS Daedalus) for a one month stay. From November 1940, through to disbandment in October 1945, it operated at RNAS Piarco (HMS Goshawk), Trinidad.
The squadron's function was the training of observers for the Fleet Air Arm. It remained part of the No. 1 Observer School, now operating out of RNAS Piarco (HMS Goshawk), an airfield located in the adjacent town of Piarco, 30 km (19 mi) east of Downtown Port of Spain, on the island of Trinidad, after moving from RNAS Lee-on-Solent on 5 November 1940. Here, as part of the school, it worked alongside two more Observer Training Squadrons: 749 Naval Air Squadron and 750 Naval Air Squadron, along with an Air Towed Target Unit, 793 Naval Air Squadron. As well as Percival Proctor and Fairey Albacore, the squadron also operated de Havilland Tiger Moth, a British biplane operated as a primary trainer aircraft, here.[5]
