SOVIET NAVY (USSR)

Ship project history: Built under 1933-1938 Naval shipbuilding program. Italian destroyer Maestrale served as prototype, from her arrangement and construction of machinery, in particular, was borrowed. The project 7 has been approved in December, 1934. Mass building of a class has begun in 1935, 53 ships were laid down, thus ships intended for Pacific, were laid down in Nikolaev and transported in the taken apart kind to the Far East for completion.
    As a whole rather successful ships, ensured to the Soviet Navy an exit on qualitatively new level. Thanks to a linear arrangement of machinery, allowed to deduce smoke ducts of all boilers into one wide and stocky funnel, "sevenths" possessed a graceful prompt outline profile. The hull was gathered under the mixed scheme: longitudinal amidships and cross-section at ship ends. As has shown operating experience, in places of transition from one system to another there were the raised stresses leading to rends and even a brake-off of the ships ends. Ships shown high speed qualities: on trials lead Gnevny reached 39.37kts at 53100hp and Ryany in 1945 shown 39.4kts at 56500hp. However an endurance was appeared significantly below than designed.
    In total on project 7 29 ships have been built; 18 more were completed under project 7u, and 6 hulls were taken apart on slipways. Reshitelny (i) under tow to Vladivostok 8/11/1938 has been wrecked by a storm on rocks S off Soviet Harbour.
