Design

Project 745 seagoing tug
The oceangoing tugs are auxiliary vessels for the Soviet Navy, later the Russian Navy.[4][1]
Project 745P patrol ship
The border patrol ships are modified versions of the original Project 745. They are armed with two 30 mm AK-230M or AK-306[lower-alpha 3] gun mounts giving them the ability to fire on surface, air and ground targets, and are equipped with the Kolonka-1 fire-control system to control these weapons.[5][1]
Project 07452 experimental vessel
The reconnaissance vessel is a version of the original Project 745, which is a testbed for SIGINT and hydroacoustic equipment.[1]
Project 745MB seagoing tug
The oceangoing tug is a modernized version of the original Project 745. It is equipped with two main diesel gensets (2 × 1,500 kW), three auxiliary diesel gensets (2 × 200 kW + 1 × 100 kW), an asynchronous propulsion motor (1 × 2,720 hp) and a bow thruster.[6][2][1]
Project 745MBS rescue tug
The rescue tug is a SAR version of the modernized Project 745MB, which is equipped with a switched reluctance propulsion motor instead of an asynchronous one.[2][1]

Externally, the Projects 745MB and 745MBS tugs can be distinguished from the original Project 745 tugs by twin funnels instead of one.
