January 1921 and was subsequently scrapped. R.35, a unique admiralty design, was almost finished when work was stopped in early 1919. R36 and R.37 were stretched R.35s. R.36 was completed after the war as a civilian airship registered as G-FAAF. R.36 had two engines from the German L71. Modifications for passenger service involved installing a 131 foot long combined control and passenger gondola to accommodate 50 passengers. R.36 suffered a structural failure of one horizontal and one vertical fin. It was repaired and served to aid the police in traffic control for the Ascot race in 1921. R.36 was damaged in a mooring accident in 1921, and while repaired R.36 never flew again. Retained for possible use as a commercial airship R.36 was broken up in 1926. Four airships of the R38 Class were started but only one completed: it was sold to the US Navy and renamed ZR-2. In June 1921 it broke up in the air over Kingston-upon-Hull before it could be delivered, killing 44 of its Anglo-American crew. The last airship that had been ordered amid the First World War was the R80; it was completed in 1920 but was tested to destruction in the following year after it was found to have no commercial use. After the end of the First World War I, Luftschiffbau Zeppelin resumed building and operating civilian airships. Under the terms of the Treaty of Versailles, Germany was prohibited from building airships with a capacity in excess of , greatly limiting the company's scope. However, a pair of small passenger airships, LZ 120 Bodensee and a sister ship LZ 121 Nordstern were built, intended for use between Berlin and Friedrichshafen. They were subsequently confiscated and handed over to Italy and France as war reparations in place of wartime zeppelins which had been sabotaged by their crews in 1919. The Zeppelin company was saved from extinction by an order for an airship, the USS Los Angeles, being placed by the US Navy; this airship conducted its first flight on 27 August 1924. The Goodyear-Zeppelin partnership would continue up until the outbreak of the Second World War. In 1924, the British Government initiated the Imperial Airship Scheme, a plan to launch airship routes throughout the British Empire. This involved the construction of two large airships, the R100 and R101, paid for by the government. The R100 was privately built by Vickers-Armstrongs using existing commercial
