Today in World War II History—September 21, 1942: British and Indian troops launch assault into the Arakan Peninsula in Burma. First test flight of Boeing XB-29 Superfortress heavy bomber, Seattle, WA.

From Sarah Sundin's blog.

The B-29 was one of the great aircraft of the Second World War and was also, during the war, one that was downright dangerous to fly due to its frequent engine failures and fires.  It's loss rate early on in China, from which many were flown, was appalling.  Nonetheless, they were an advance that could be regarded as generational.

Forever associated with Hiroshima and Nagasaki, the plane became the world's first nuclear bomber, a status it retained for a while post-war.  By the Korean War, however, they were beginning to show their vulnerabilities in the new jet and rocket age. The B-36 resulted in them being reclassified as a medium bomber, an odd thought, and the B-29 was retired in 1960, and overall long run for a bomber of that period.  A late variant, the B-29D, which was reclassified as the B-50, continued on in limited use until 1963.  Ironically, a version copied by the Soviet Union from an example that landed on their territory during the war, the TU-4, remained in active service slightly longer and also saw service with the Red Chinese, meaning that for a time the airplane equipped both sides in the Cold War.

The aircraft was not introduced into service until 1944 and its use was limited to the CBI and Pacific Theaters. Post-war, the British were briefly equipped with a limited number, a small number of which went on to serve with Australia.  An airliner version went on to become an early post-war transoceanic airliner, one of the ones that effectively put an end to flying boats.
