Before the dropping of the atomic bomb on Japan, the RAF's Bomber Command had been mustering a sizeable bomber force within Bomber Command, called Tiger Force, to take the bombing offensive to Japan. With the war over, this force was cut down and retained as part of Bomber Command, but squadrons within it were rotated to Middle and Far East bases both for training purposes and to be there in case of fresh outbreaks of fighting as happened in Indonesia. With the end of war in Europe, No. 9 Squadron was allotted to the Tiger Force, with the Squadron arriving at Salbani, India, in January 1946 after the Japanese had surrendered. The Lancasters carried out photographic duties and returned to the UK in April.
Also from Wikipedia:- "Tiger Force was the name given to a World War II British Commonwealth long range heavy bomber force, formed in 1945, from squadrons serving with RAF Bomber Command in Europe, for proposed use against targets in Japan. The unit was scheduled to be redeployed to the Pacific theatre in the lead-up to the Allies' proposed Allied invasion of Japan. The unit was disbanded after the bombing of Hiroshima and Nagasaki ended the war."
