A76 Boeing Washington

Originally allocated to the Avro Tudor airliner, which was intended to be built in Australia in conjunction with Lincoln bomber production, the cancellation of this aircraft meant that the A76 allocation became redundant.

In 1952 the serial A76 was re-allocated to the Boeing B-29 Super Fortress, 88 of which were on loan to the RAF as Washington B Is. The prototype B-29 had first flown on 21 September 1942, and during World War II the B-29's 'Enola Gay' and 'Bockscar' dropped the first two atomic bombs on 6 and 9 August 1945, which brought about the Japanese surrender on 14 August 1945.

Two Washingtons, WW 353 and WW 354, were flown to Australia by RAAF aircrews and arrived at ARDU Trials Flight (later ATU) on 26 September 1952 and 12 December 1952 respectively. They were used on a number of trials for the UK Ministry of Supply (UKMOS) and by 1956 had flown a total of 174 hours in RAAF service.

During 1956 the two aircraft were placed in storage pending disposal decisions from the UKMOS and the US Air Force. The engines were later removed and the Washington airframes were sold for scrap in 1957.
