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. [3]
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.
Externally, the Projects 745MB and 745MBS tugs can be distinguished from the original Project 745 tugs by twin funnels instead of one.
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]
A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs), each of which carries a nuclear warhead and allows a single launched missile to strike several targets. Submarine-launched ballistic missiles operate in a different way from submarine-launched cruise missiles.
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbors or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, and some are icebreakers or salvage tugs. Early models were powered by steam engines, which were later superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours.
The Gepard-class frigates, Russian designation Project 11661, is a Russian class of frigates that were intended as successors to the earlier Koni-class frigates and Grisha, and Parchim-class corvettes. The first unit of the class, Yastreb (Hawk), was laid down at the Zelenodol'sk Zavod shipyard at Tatarstan in 1991. She was launched in July 1993, after which she began fitting out; fitting was nearly completed by late 1995, when it was suspended due to lack of funds. Renamed Tatarstan, the ship was finally completed in July 2002, and became the flagship of the Caspian Flotilla. She has two sister ships, Albatross, and Burevestnik, which was still under construction as of 2012.
The Bora-class, Soviet designation Project 1239, hoverborne guided-missile corvette of the Russian Navy, also bears the NATO class name "Dergach", is one of the few types of military surface effect ship built solely for marine combat purposes, rather than troop landing or transport. The first vessel produced under this designation was Sivuch, which was later renamed Bora. It is one of the largest combat sea vehicles with catamaran design.
The Poti class was the NATO reporting name for a group of anti-submarine warfare (ASW) corvettes built for the Soviet Navy. The Soviet designation was Project 204 small anti-submarine ships. These ships were the first Soviet warships powered by gas turbine engines; two propellers were mounted in tunnels to give a very shallow draught. A twin 57 mm (2 in) gun mounting provided self-defence. Three ships of the class were exported to Romania and six to Bulgaria during the Cold War. By 2008, all ships of the class were no longer extant.
Vinnytsia (U206) was an anti-submarine corvette of the Ukrainian Navy. Prior to joining the Ukrainian Navy she was a former KGB Border Guard patrol ship named Dnepr. In March 2014, she was seized by Russian soldiers and de facto came under control of the Russian Black Sea Fleet. The ship was returned to the Ukrainian Navy from Crimea on 19 April 2014.
The Coast Guard of the Border Service of the FSB, previously known as the Maritime Units of the KGB Border Troops, is the coast guard of Russia.
The Pacific Fleet is the Russian Navy fleet in the Pacific Ocean.
The Okean class, Russian designation Project 22100 Okean (ocean), is a class of oceanic patrol vessels being constructed by Zelenodolsk Shipyard for the Russian Coast Guard. The vessels of this class are intended for protection of Russia's exclusive economic zone (EEZ), providing support to combat and rescue missions, fire fighting or fisheries protection. Apart from this, the ships will be involved in ensuring actions of the FSB of Russia by fighting terrorism and piracy, goods smuggling, drug trafficking or illegal migration.
The Vosh-class river patrol craft, also known in Soviet designation as Project 1248 Moskit, which has the Project 12481 variant. Both are Russian Coast Guard vessels. The patrol craft is designed to operate in rivers and protect/secure Russian maritime borders, enforce navigational rules and other laws, search and rescue. They work alongside other patrol craft of the Russian Coast Guard and Navy, such as the Piyavka-class and the Ogonek-class river patrol craft.
The MPK-105 was a Parchim-class corvette in the Soviet Navy and later Russian Navy.
The MPK-213 was a Parchim-class corvette in the Soviet Navy and later Russian Navy.
The MPK-216 was a Parchim-class corvette in the Soviet Navy and later Russian Navy.
The MPK-219 was a Parchim-class corvette in the Soviet Navy and later Russian Navy.
Chernihiv(U205) was a Grisha II-class anti-submarine corvette of the Ukrainian Navy. Prior to joining the Ukrainian Navy she was a former Soviet Navy corvette named Izmail.
Oryol is a Project 11351 Nerey-class frigate of the Coast Guard of the Border Service of the FSB of Russia. Previously the ship served in the KGB Border Troops Naval Service as Imeni XXVII siezda KPSS.
Dzerzhinskiy is a Project 11351 Nerey-class frigate of the Coast Guard of the Federal Security Service of Russia. As of 2022, Dzerzhinskiy is the only active vessel in the Coast Guard of Russia that was awarded with the Order of the Red Banner.
