The Bombing of Singapore (1944–1945) was a military campaign conducted by the Allied air forces during World War II. United States Army Air Forces long-range bomber units conducted 11 air raids on Japanese-occupied Singapore between November 1944 and March 1945. The Singapore Naval Base had become the most important facility of the Imperial Japanese Navy outside the Japanese home islands. As such, most of these raids targeted the naval base and dockyard facilities on the island.
The raids had mixed results. While significant damage was inflicted on Singapore's important naval base and commercial port, some raids on these targets were not successful and other attacks on oil storage facilities on islands near Singapore were ineffective. The Allied air attacks were, however, successful in raising the morale of Singapore's civilian population. The overall number of civilian casualties from the bombings was low, though one attack rendered hundreds of people homeless and civilian workers were killed during attacks on military facilities. Only nine B-29s were shot down during this bombing campaign.
