No. 9 Squadron was a heavy bomber squadron for the length of the Second World War, flying the Vickers Wellington for the half of the war, and the Avro Lancaster for the second half.
For the first four months of the war, No. 9 Squadron conducted day-light anti-shipping sweeps over the North Sea, taking steadily increases loses, until 18 December 1939, when five aircraft were shot down by German fighters. After that the squadron concentrated on night time operations.
The main result of this was that No. 9 Squadron, like the rest of Bomber Command, had a relatively quite time until the spring of 1940. This ended in April 1940 with the German invasion of Norway. A detachment from No. 9 Squadron moved to Lossiemouth in Scotland, to support the allied expedition to Norway.
No. 9 played a full part in the strategic bombing offensive against Germany. However, it was also used on special operations, including most notably the raid of 12 November 1944 which finally sank the German battleship Tirpitz. For this mission No. 9 Squadron (with No. 617) flew Lancaster B.Mk I Specials, modified to carry the 12,000lb Tallboy bomb.
No. 9 was one of the squadrons allocated to Tiger Force, the RAF contribution to the invasion of Japan. Unlike many other squadrons allocated to that force, No. 9 did at least reach India, arriving there in January 1946 to spend four months on photographic survey duties.
