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[d] 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 (2,720 metric horsepower or 2,680 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]
Project 745MB and 745MBS tugs differ externally from original Project 745 tugs by having twin funnels instead of single.

- The Russian Coast Guard Project 745P border patrol ship Bug and the Yamaha S-329-class border patrol boat Steregushchiy during the Russian-Japanese exercise in Aniva Bay in 2009
- The Soviet Navy Project 07452 experimental vessel OS-572, a de facto reconnaissance vessel, between 1987 and 1991
- The Russian Navy Project 745MB seagoing tug MB-12 at Cape Zhelaniya in 2020
- The Russian Navy Project 745MBS rescue tug Viktor Konetsky and IRIS Shahid Mahdavi (P313-1) during the CHIRU exercise in 2019
History
A Project 745P border patrol ship was involved in an incident involving Greenpeace vessel where the Russian ship fired warning shots, and later seized a Greenpeace vessel after they attempted to board an oil rig in the Arctic in 2013.[7]
Another Project 745P border patrol ship rammed a Ukrainian tug in the Kerch Strait on November 25, 2018.[8]

- One Project 745 tug—the Ukrainian Navy seagoing tug Korets, ex–Soviet Navy's MB-30 (1973)—that was captured by the Russian Armed Forces in the Port of Berdiansk during the Russian invasion of Ukraine on February 28, 2022.[1]
