"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.
