Sorum-class tugboat explained

The Sorum class, Soviet designation Project 745, is a series of seagoing tugs built for the Soviet Navy and KGB Border Troops, and later operated by the Russian Navy and FSB Border Service.

These vessels perform the standard missions of a seagoing tugboat with other missions such as protecting and patrolling Russian maritime borders, enforcing navigational rules and law enforcement, search and rescue, and fisheries protection.

Design

Project 745 seagoing tug: The oceangoing tugs are auxiliary vessels for the Soviet Navy, later the Russian Navy.
Project 745P patrol ship: The border patrol ships are modified versions of the original Project 745. They are armed with two 30 mm or gun mounts giving them the ability to fire on surface, air and ground targets, and are equipped with the fire-control system to control these weapons.
Project 07452 experimental vessel: The reconnaissance vessel is a version of the original Project 745, which is a testbed for SIGINT and hydroacoustic equipment.
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 × 2720abbr=onNaNabbr=on) and a bow thruster.
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.

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

History
