"B-2LM" (Russian: "Б-2ЛМ") is a Soviet 130 mm two-gun naval artillery turret, based on the "B-13" ("Б-13") gun.

The TTZ (тактико-техническое задание, tactical-technical assignment) for a twin-130 mm gun turret was ordered on April 15, 1936.

A prototype unit would be tested in the LMZ (Leningrad Metal Plant) throughout July—August 1940.

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.
