Uragan-class guard ship
The ''Uragan''-class guard ships were built for the Soviet Navy as small patrol and escort ships. Eighteen were built in the 1930s and served during World War II in all four of the Soviet Fleets: Baltic, Black Sea, Northern and Pacific. Four were lost during the war and the rest remained in service until the late 1950s in various secondary roles. The official Soviet designation was Project 2, Project 4 and Project 39, but they were nicknamed the "Bad Weather Flotilla" by Soviet sailors by virtue of their meteorological names.
==Design==
By the mid-1920s the Soviet Navy wanted to replace the few old Tsarist torpedo boats that it had left acting as guard ships. The initial requirement was for a ship not to exceed , armed with two old guns, three torpedo tubes and could carry mines as necessary. It was to be powered by four Beardmore diesel engines imported from the United Kingdom, but this plan was thwarted by Soviet financial support for the miners during the 1926 United Kingdom general strike. The preliminary designs had to be revised for steam propulsion, a task greatly complicated by the break in Soviet ship construction between 1917 and 1924 when no ships, naval or commercial, had been built and many experienced naval architects had either fled the country, found new jobs, or were politically suspect and not allowed to work. It proved impossible to work within the 300 ton limit with steam turbines and the tonnage limit was increased to 350 tons when the Navy approved the preliminary design on 26 November 1926. Detailed design of the ship and its power plant was assigned to the Zhandov Shipyard in Leningrad. They proposed two alternative steam pressure power plants; one low-pressure () and one at . The Navy rejected the high-pressure design and ordered studies evaluating "a three-shaft combined power plant with 2-shaft geared turbines plus 1-shaft diesel engine for cruising, diesel-electric, and diesel."〔Budzbon and Lemachko, p. 143〕 These were rejected and the original two-shaft turbine power plant was selected. At the same time it became clear that the new 350 ton limit was also inadequate and 400 tons would be needed. The twelfth design was approved on 23 June 1927 as the Project 2.〔Budzbon and Lemachko, pp. 140-3〕
