Nobile USSR-V5
Russian Empire Airship USSR-V5
The Russian "Dirizhablestroem" was staged with developing the production of semi-rigid airship types. In order to speed up the execution of the tasks, in 1932 in the Soviet Union invited Italian Umberto Nobile, who was to head the technical management of the project.
In 1931 Umberto Nobile left Italy to work for the next four years in the Soviet Union where he helped with the Soviet semi-rigid airship programme. There is an obvious Nobile influence in the design of the airships USSR-V5, and SSSR-V6 OSOAVIAKhIM.
By the end of February 1933 USSR-V5 was prepared as the first semi-rigid airship in the. On April 27, 1933 Nobile first took to the air. This airship was of small size, its volume was only 2,340 cubic meters. It was explained that the USSR B-5 was conceived as a semi-rigid airship, established to give Russian designers practical eserience with Italian semi-rigid systems, and identifying those problems that might face in the USSR in the production of airships larger volume. In addition to the B-5 was planned to conduct training of ground staff and pilots.
USSR-V5 1933
In May 1933, after passing a series of municipal acceptance tests, B-5, was admitted to the civilian air fleet. In 1933, Nobile made over a hundred flights. The experience gained during its construction, and operation was the basis for the construction of the largest airship in the USSR-6 "Osoaviakhim."
The CCCP B-5 (USSR V5) was dismantled in 1934 – her ‘envelope’ was leaking and generally unreliable. While a new ‘envelope’ development has been in progress, lightning struck the hangar near Moscow where parts of the dirigible were stored. Everything went down to ashes, not only cases with B-5 parts, but her sistership B-4 (also dismantled) and a brand-new B-7 as well.
