"B-2LM" ( Russian: "Б-2ЛМ") is a Soviet 130 mm two-gun naval artillery turret, based on the " B-13" ("Б-13") gun. Production started in 1939. "B-2LM" was established on several Soviet Navy ships, including the destroyer leader Tashkent, the Ognevoy-class destroyer (Project 30 and 30K), and the Skory-class destroyer (Project 30bis). However, it had a relatively low rate of fire and had a maximum elevation of 45 degrees making it incapable of anti-aircraft fire.
General characteristics
- Maximum laying speed: vertical - 9.85 degrees per second, horizontal - 9.7 degrees per second
- Shell weight: 33.5 kg (74 lbs)
- Initial velocity of the shell: 870 m/s
- Range: 25,597 m
History
The TTZ (тактико-техническое задание, tactical-technical assignment) for a twin-130 mm gun turret was ordered on April 15, 1936. The preliminary design for the B-2LM was approved on October 19, 1938. Later, the completed design was designed by OKB-172 (formerly Motovilikha Gun Plant and the Motovilikha Machine-Building Plant, later renamed the Perm Machine-Building Plant) and officially accepted on 16 February 1939. A prototype unit would be tested in the LMZ (Leningrad Metal Plant) throughout July—August 1940.
Range testing occurred in two phases with 240 firings, the first from 4 December 1940 until 27 January 1941 (55 days) and the second from 27 April to 27 May 1941 (31 days), totalling 86 days of testing. During testing, the B-2LM performed well and was nominated for service, with three turrets finally being installed on the destroyer leader Tashkent by 8 July 1941, in place of the 130 mm B-13 naval gun. Tashkent would later undergo state ship trials in Sevastopol Bay in July 1941, bearing the new armament. [1]
However, five B-2LM turrets were abandoned in Shipyard No. 183 in Nikolayev (now Mykolaiv) before its capture on 16 August 1941. Serial production would commence in 1942 in Shipyard No. 402 ( Severodvinsk), continuing until 1953 in the Bolshevik Plant, Severokramatorsk Machine-Building Plant, and Plant No. 75 ( Yurga). [2]
