Once the surrender of Germany had occurred, plans were made to send a "Very Long Range Bomber Force" known as Tiger Force to participate in the Pacific war against Japan. Made up of about 30 British Commonwealth heavy bomber squadrons, a reduction of the original plan of about 1,000 aircraft, the British bombing component was intended to be based on Okinawa. Bomber Command groups were re-organised for Operation Downfall but the Soviet invasion of Manchuria and the Bombing of Hiroshima and Nagasaki occurred before the force had been transferred to the Pacific.
