 became involved because it saw the scheme as a means of continuing airship technology and operational experience at modest cost via subsidies, just as it subsidized British passenger ships. Nevil Shute Norway wrote that: It was generally agreed in 1924 that the aeroplane would never be a very suitable vehicle for carrying passengers across the oceans, and that airships would operate all the long-distance routes of the future. We were all quite wrong, of course but at that time it seemed reasonable; no aeroplane had yet succeeded in crossing the Atlantic from east to west, whereas a German airship, the Graf Zeppelin

The two ships were soon labelled the "Capitalist" ship (R100) and the "Socialist" ship (R101). Further airships would include the best features from both.

The R100 was a generally conservative design, with certain parts – for example, gas valves – bought from the Zeppelin company

, and (eventually) used aeroplane engines. The R101 was a very innovative design with novel and often radical changes in structure, gas bag wiring, gas valves, and it used diesel engines for safety (though they used petrol starting engines, only one of which had been replaced by a diesel engine).

Both were delayed. The R100 by the poor construction facilities at Howden

RNAS Howden was an airship station near the town of Howden south-west of York, UK. Opened on 26 June 1916 during the First World War, to cover the East Coast ports shipping from attacks by German U-boats. From 1916 to 1918 Howden was a Royal Naval Air Service establishment...

, and labour troubles - a product of the necessity of delivering the airship to a fixed price. The R101 was delayed by the myriad of technical and developmental problems arising from the many innovative systems and design features. Both airships were overweight, the R101 badly so, and neither had an adequate payload for the proposed commercial services.

In August 1930, R100 made the transatlantic journey to North America, vising Quebec, Montreal and Toronto.

R101 was dispatched on a flight to India under marginal conditions in October 1930, with a hastily issued Certificate of Airworthiness. She crashed soon after leaving on a stormy night in France. The R101 had had an extra gas cell inserted in the middle to give adequate lift for the trip to India, and this trip was to be the first full-load test with the additional section. The exact cause is still a matter of dispute amongst airship enthusiasts and historians to this day. Masefield lists thirteen factors; without any one of them the disaster might not have happened. The desire of the all involved to achieve a flight to India before the conclusion of the 1930 Imperial Conference (at which decisions would be taken on the future of the airship programme) led to a premature flight in adverse weather conditions.

Proposals in 1930 (initially called Project H) were for scheduled airship services from 1931 from Cardington to Karachi and Montreal with R100 and R101 (both lengthened with additional bays) until 1934 when additional and larger airships, the R102

 (an enlarged R101 with 8300000 cubic feet (235,029.8 m³) capacity) and the R103 (of around 9500000 cubic feet (269,010 m³) capacity) would be available. By 1935 the four airships would offer monthly return services to Montreal and Karachi and a weekly service to Ismalia in Egypt. Australia would come into the pattern in 1936, and an even larger airship the R104 was proposeed.

But on 31 August 1931 the Cabinet decided to abandon British airship development, although Cardington would still keep a watching brief on overseas developments. The R100 was broken up. Proposals for the planned R102, R103 and R104 airships were now all abandoned. The loss of R101, the gathering world depression, and doubts about the optimistic financial forecasts, were all factors in these decisions.
