No. 3 (Coastal) Operational Training Unit RAF (3 (C)OTU), was a training unit of the Royal Air Force, within No. 17 Group RAF, which was part of RAF Coastal Command. The unit started operating from late 1940 and disbanded at the start of 1944, being absorbed into No. 6 OTU.[1]

## History[edit]

No. 3 (Coastal) Operational Training Unit RAF was formed at RAF Chivenor on 27 November 1940.[1] It was tasked with training aircrew for Avro Anson, a British twin-engine, multi-role aircraft, and Bristol Beaufort, a British twin-engined torpedo bomber aircraft, from No. 1 (C) OTU. Aircrew training for Bristol Beaufort aircraft had been intended for No. 5 (C) OTU, and No. 3 (C) OTU was initially designated for training aircrew for Vickers Wellington, a British twin-engined, long-range medium bomber, and Armstrong Whitworth Whitley, a British medium bomber aircraft, however, slow progress with the construction of new airfields meant the Vickers Wellington and Armstrong Whitworth Whitley aircrew training went to RAF Kinloss, and later RAF Silloth, with the Bristol Beaufort aircrew training remaining at RAF Chivenor.[2]

On 29 July 1941 the aircrew training for the Whitley and Wellington aircraft moved to RAF Cranwell as a lodger unit, and the Bristol Beaufort aircrew training section became No. 5 Operational Training Unit RAF (5 OTU), when it re-formed at RAF Chivenor on 1 August 1941.[2]

No. 3 (C) OTU was the first unit to be officially based at RAF Haverfordwest. Initially, on the 30 November 1942, four of its Armstrong Whitworth Whitley aircraft, along with ground crew, moved in from RAF Cranwell. Its role was to provide aircrew with reconnaissance training and by June 1943 its full complement of aircraft had arrived.[3] Around the end of April 1943, aircrew training for Armstrong Whitworth Whitley had ended and the unit reorganised its Flights. The Vickers Wellington conversion training was designated ‘A’ Flight, with the two Operational Training flights ‘B’ Flight and ‘D’ Flight. ‘C’ Flight was for the Avro Anson aircrew training.[2]

No 3 (C) OTU's Armstrong Whitworth Whitley aircraft were all eventually withdrawn, being replaced with more Vickers Wellington aircraft. Lack of space at RAF Haverfordwest, meant 'O' Flight operated out of RAF Haverfordwest’s satellite airfield, RAF Templeton.[4] 'O' Flight of was equipped with fourteen Avro Anson I aircraft,[5] and was tasked with the training of aircrew for general reconnaissance and particularly the use of Leigh Lights. This was successfully used against Kriegsmarine submarines by RAF Coastal Command.[6] The flight left RAF Templeton in December 1943, moving to RAF St Athan where it was renamed No. 12 Radio School RAF.[5]

The unit was disbanded on 4 January 1944 at RAF Haverfordwest and absorbed by No. 6 Operational Training Unit RAF (6 OTU).[7]
