B-13 (130 mm)

Description

The 130 mm/50 B13 Pattern 1936 was a 130 mm (5.1 in) 50 caliber Soviet naval gun. The gun was used as a standard destroyer weapon during World War II, and it was also used as a coastal gun and railway gun. The gun was produced in three different versions which all had incompatible ammunition and range tables. Mountings for the weapon included single open mounts and twin turrets. Besides the Soviet Union, the gun was used on ships sold or donated to Poland, People's Republic of China, Egypt and Indonesia. Finland captured five guns during Continuation War and used them until the 1990s.

History

In 1929 design work began in the Soviet Union for a new 130 mm 45 caliber submarinedeck gun that would have the same external ballistics as the older 130 mm/55 B7 Pattern 1913 gun. It was intended for the gun to use a wedge lock and fixed ammunition, but the plans were changed already before the prototype was ordered. Blueprints and a prototype was ordered from Bolshevik Plant no. 232 in 1930. The design bureau director was N. N. Magdasijev and project leader G. N. Rafalovits. Others involved in the design were S. A. Morozov, S. A. Zalazaev, B. A. Lever, V. M. Rosenberg and V. I. Kudrjashov. The gun design was changed from submarine to destroyer weapon using separate instead of fixed ammunition and in 1932 new specifications included a change from 45 to 50 calibers and a screw breech block instead of wedge block. During test firing in 1934—35 several shortcomings were found in the gun design, particularly with the breech and loading mechanism. Because the Leningrad-class destroyers that were supposed to use the guns were already under construction the 130 mm B-13 gun was accepted for mass production in 1935 and the first twelve guns were finished during the same year.
