In full: His Majesty's Airship R100. It was a privately designed British airship built as part of a two-ship competition to develop a commercial airship service for use on British Empire routes as part of the Imperial Airship Scheme. The design team was led by Barnes Wallis. The other, the ill-fated R101, was built by the British Air Ministry, but both airships were funded by the government. The R100 made a series of trial flights and a successful return crossing of the Atlantic in July-August 1930, but following the crash of the R101 in October 1930 the Imperial Airship Scheme was terminated and the R100 was broken up for scrap.
