No 109 Squadron was formed at Lake Down in May 1917 as a day bomber unit. It spent some time training and disbanded in July 1918 before becoming operational.

On 10 December 1940 the Wireless Intelligence Development Unit was redesignated No 109 Squadron. During the next two years it was involved in research and the development of radio counter measures and new radar aids. In August 1942 the unit moved to RAF Wyton and became one of the earliest units to join the Pathfinder Force. In December it received Oboe equipped Mosquitos and pioneered its use in operational service. The squadron remained an Oboe unit for the rest of the war. It had the distinction of dropping the last RAF bombs on Berlin during an attack on 21 April 1945.

One of the unit’s members won the Victoria Cross. Sqn Ldr R A M Palmer was awarded the decoration posthumously “in recognition of most conspicuous bravery”. He was flying a No 582 Squadron Lancaster at the time and acting as Oboe leader for a bomber force attacking Cologne on 23 December 1944.

On the 30 September 1945 the squadron disbanded but on the following day No 627 Squadron was renumbered No 109 Squadron. It converted to jet bombers in July 1952 and took these to Cyprus during the Suez Crisis of 1956.
The unit finally disbanded on 1 February 1957.
