B-871 Alrosa – Big-Tailed Kilo

B-871, a Kilo class submarine, has an interesting history. This continues our series of unusual Soviet/Russian submarines. Following on from many classes of Soviet attack boats, the Kilo design (NATO designation for these) was a leap forward in capability, with the first boat commissioned in 1980. Kilos had a very different overall hull shape from earlier diesel-electric boats, such as the Tango and Foxtrot classes. With the same armament of six 533mm torpedo tubes and naval mines, they were smaller and harder to detect than Tangos, and were clad in the same sound-absorbing anechoic rubber tiles. More than forty original Project 877 Paltus (the Russian designation) boats were built at five shipyards. Several units were exported to India, China, Iran, Romania, Poland, and Myanmar. Thirty more boats of the “Improved Kilo” or Project 636 Varshavyanka class have also joined the fleets of Russia, Algeria, China, and Vietnam, with more updated boats still under construction.

B-871, built at Gorky shipyard, transited the Volga and Don River/canal systems to its new homeport of Sevastopol, the headquarters of the Black Sea Fleet (BSF), to be commissioned Dec. 1990. It has spent most of its career in Sevastopol, and has now served three navies: The Navy of the Soviet Union, the Ukrainian Navy, and the Russian Navy.

Upon the dissolution of the USSR, in late December 1991, the crew in Sevastopol voted to join the newly-independent Ukraine, in a process we described in our post on the Ukrainian Navy: The Only Easy Day was Never. This new attack boat would have been one of the most able of a small force of mostly abysmal submarines handed over to Ukraine. It would have been a good running mate to the other functional boat, the older foxtrot class submarine Zaporizhzhia.

The Russian official version of this is different, with a crew uprising reported as suppressed immediately and no acknowledgement of Ukrainian Naval service. The submarine was frequently non-operational during the mid-1990s, as the Ukrainian Navy did not have the inventory of parts or the spare batteries to safely operate the sub.

B-871 was back in Russian service by 1997. According to the contemporary edition of Jane’s Fighting Ships, it was extensively modified during 1998. It was fitted with an enormous pump-jet propulsor in place of the usual screw, and received the unique Russian designation of Project 877V. At the time, this was cutting-edge technology for a Russian military submarine. Western powers, such as Britain, had built pump-jet propelled submarines. Adapting the proven Kilo design was a sensible way to trial the technology. Sometime during the early millennium the sub was named “Alrosa,” reflecting its’ sponsorship by this group of diamond-mining corporations.

By the 2010s, after years of uneventful service, Alrosa was supposed to have left Sevastopol to join the Baltic Fleet (though the boat should be close to retirement). The BSF was to upgrade to all improved Kilo type boats. This has not happened, and the current Russian War in Ukraine ensures the boat will not leave the Black Sea. Alrosa was in very lengthy refit which had just finished when Russia invaded Ukraine. The refit also has reportedly involved an enormous upgrade to the lethality of the submarine – launch tubes to be able to operate Kalibr cruise missiles.

Russian Black Sea Fleet – 2022-2024 War Losses

A brief visual survey of Russian Black Sea Fleet warship losses – reality vs. false reporting

The war losses the Russian Black Sea Fleet (BSF) has suffered during the current Invasion of Ukraine are historically significant. At the time of writing, they are the most severe losses sustained by a major naval service since 1945.* In the Black Sea’s confined area of operations, the loss of a few major units is significant. Since the Bosporus and Dardanelles Straits are closed to warships from warring navies, Russia can’t reinforce the BSF with the numerous units now present in the Mediterranean or elsewhere.** The rest of its navy- the third largest by most measurements-is effectively sidelined.***

For information about the Ukrainian Navy units lost during both the 2014 Russian Annexation of Crimea and now the 2022 Russian Invasion, please see our recent post “The Ukrainian Navy’s Fighting Ships – The only easy day was Never.” We also have more detailed ship listings for Ukraine and Russia. All satellite imagery below shows actual units of the BSF, home-ported at the main naval ports of Sevastopol or Novorossiysk. This post was updated as of March 2024. We removed a section of this post which featured units erroneously reported as destroyed, as these became increasingly irrelevant to track based on the confirmed totals of damaged and destroyed Russian warships.

The 2022-2024 BSF casualties: 11-12 vessels, ca. 34,170 tons destroyed; 2-3 vessels, 8,800 tons damaged:

Moskva, Slava class/project 1164 Atlant missile cruiser (1983-14 April 2022). LOA 612’/186.5m TDISP 11,500 tons. Formerly the Soviet Navy’s Slava, built at Mykolaiv. Slava and the other units of the class were updates to a series of missile cruisers armed with so-called “carrier killing” anti-ship missiles. They were intended as an economical alternative to the massive nuclear-powered Kirov class. Slava, renamed Moskva after the Soviet collapse, served as the longtime flagship of the Black Sea Fleet. It was engaged in blockading the Southern Naval Base of the Ukrainian Navy at Lake Donuzlav, during the 2014 Annexation of Crimea. At the beginning of the Russian Invasion of 2022, it conspicuously participated in the attack/seizure of Snake Island on 24 February 2022. Extensively damaged by two Ukrainian Neptune Anti-ship missiles 13 April 2022, it sank the next day while efforts were underway to tow it back to Sevastopol. This is the first flagship of a major fleet lost since the Second World War, and the largest warship lost in combat since at least the Admiral Belgrano (Argentinian Navy), a veteran former USN cruiser which was sunk during the 1982 Falklands War. During late April, the Kommuna, the elderly salvage vessel, was sent to the wreck to recover equipment or human remains.

Reportedly this frigate, the BSF flagship after the destruction of Moskva, was damaged during the 29 October 2022 attack by USVs and UAVs (surface and air drones). Earlier reports of damage sustained on 6 May 2022 appear to have not been accurate.

Caesar Kunikov (1986) destroyed 13 February 2024 by multiple USV attacks off the Crimean coast at Alupka. It was already been damaged 24 March 2022 at Berdyansk when Saratov landing ship was destroyed. This ship’s captain was killed and the foredeck was observed to be on fire. When the Ropuchas fled the burning port facilities, one ship circled, seemingly out of control and “Bismarking” South of the port.

*During the Falklands War, the next most significant naval actions of the postwar era, the Royal Navy lost two destroyers, two frigates, a landing ship, and a landing craft, which total to around 22,100 tons, not counting the SS Atlantic Conveyor, which was a large merchant ship engaged in military activities.

** The terms of the 1936 Montreux Convention that limits access to the Black Sea are more complicated than this, however, the result is that Russia cannot reinforce its Black Sea Fleet.

***Reports indicate some of the Caspian Sea Flotilla ships have been involved in a limited way, firing Kalibr missiles at Ukrainian targets.

The Ukrainian Navy’s Fighting Ships – The Only Easy Day was Never.

The losses the Ukrainian Navy has sustained as a result of two occupations make it unique amongst 21st Century navies. The great navies of the World, since 1945, have undergone only gradual transition to more modern and capable classes of warship, with the tragic loss of units and crew being an exceptionally rare occurrence. By contrast, the Navy of Ukraine lost its headquarters, two major bases, and 75% of its fleet during the Russian Annexation of Crimea, 2014. In the current 2022 Russian War, it has already lost many of the remaining units. This post will provide a brief summary of the warships of Ukraine, and what happened to them. For a ship-by-ship accounting of the fleet, please see our newly-released pages.

In the heady days following Ukraine’s Independence Day, 24 August 1991, the new navy was envisioned as a modern, well-rounded regional force, able to project naval presence in the Black Sea, with a mix of frigates, submarines, and corvettes. It was never intended to compete with the Russian Black Sea Fleet, which it had peacefully been created out of. January 1992 negotiations between presidents Boris Yeltsin of Russia and Leonid Kravchuk of Ukraine even agreed to an equitable split of the fleet. The first Ukrainian warship in the modern era was the Petya class light frigate SKR-112, whose crew and senior officer, Captain Mykola Zhybarev, declared their allegiance to the new state on 21 July 1992, before leaving the Russian base at Sevastopol for Odessa, under the real threat of destruction. The transfer of units, assets, and bases was established in a series of international agreements during the mid-1990s. It was a painful and drawn out separation, complicated by Ukraine granting the Russian fleet a lease to continue using facilities on the Crimean Peninsula, including major port facilities at Sevastopol. The terms for the 20-year lease would have expired in 2017.

Like many of the former Soviet Republics, Warsaw Pact countries, and those that had been in the orbit of the USSR, Ukraine inherited a mixed bag of legacy Soviet warships and vessels from the old KGB Border Guard; some units were relatively modern or in decent material condition, but quite a few were worn-out.* Of the four guided missile frigates, two older Krivak II class were beyond all economical repair, and were promptly decommissioned. Of four submarines, only one elderly Foxtrot class submarine had any prospect of joining the fleet. A variety of missile corvettes of the Grisha and Tarantul classes were transferred along with Pauk class patrol boats.

Some remarkable ships were building at the 61 Communards shipyard at Mykolaiv at the very twilight of the Soviet empire: A Kuznetsov class aircraft carrier, a large depot ship for nuclear submarines, and a Slava-class cruiser.** The transfer of ownership of the gargantuan facility left Ukrainian governments struggling with a way forward for disposing of these white elephants. For a time, work resumed on the massive 610-foot long, 11,500 ton cruiser, which was to have been named Ukrayina. It received a ship’s badge and a crew was even assigned to prepare for entry into service.

Other project on the ways at Mykolaiv included what became the flagship, a Krivak III class frigate originally intended to join the other similar ships in KGB/FSB border guard service. A Grisha V class corvette, Ternopil, was eventually completed in 2003.

The years after 2000 have been difficult ones for the Ukrainian Navy, as major procurement of new surface units to replace the aging Soviet ships has mostly not advanced, as the navy has been under-funded and had trouble retaining personnel. The relationship with Russia, and most immediately, the Black Sea Fleet, also deteriorated. Vladimir Putin’s regime, during the early 2000s, began stoking the flames of separatism in Crimea and Eastern Ukraine, and worse still, questioning the very existence of Ukraine as a separate entity. Because of the lease of the port facilities, there was little separation from Russian forces as Putin’s rhetoric ratchetted up.

The February 2014 Annexation of Crimea by Russia was almost the end of an independent Ukrainian Navy. All ships in Sevastopol, Ukraine’s main naval base, were immobilized, blockaded, and seized. The headquarters and the main docking area for the navy was captured, and other ships in Strilets’ka Bay were cut off, blockaded, and eventually also seized. Some senior officers defected to the Russian fleet, and the loyalties of the rank-and-file was also divided. Fortuitously, the flagship, Hetman Sahaidachny, was participating in international anti-piracy efforts off the coast of Somalia, and returned to Odessa, which became the new headquarters.

Seized units at Sevastopol, still interned Aug. 2020, including the Ropucha landing ship Konstantin Olshansky, the submarine Zaporizhya, and the intelligence ship Slavutich.

The Southern Naval Base on Lake Donuzlav was also bottled up, when the Russians sank a retired cruiser, Ochakov (originally built at Mykolaiv), and other small vessels across the narrow entrance to the lake. Despite efforts to escape, this entire force was seized by Crimean separatists.

Southern Naval Base, May 2014, interned Ukrainian ships. From left to right, these are the Grisha class ships Vinnytsia U-206 (returned and seized again 2022), Ternopil U-209 (not returned), Pauk class Khmelnytskyi U-208 (not returned), Minesweepers Chernigov U-311 and Melitopol U-330 (both not returned), Horlivka A-753 Freighter, another Pauk class, a Pozharny class fire boat.

Today, only the rusted hulk of the Ochakov remains near the former base, awaiting scrapping. The loss of both landing ships, the minesweepers, almost the entire force of Grisha corvettes, and the entire facility was a severe blow. Some ships were returned later, but these have mostly consisted of older ships.

The Russians came up with excuses not to return the updated Grisha corvettes, any of the minesweepers, the larger, more modern Ropucha-class landing ship, the single submarine, the intelligence vessels. Some of these remain interned. The landing ship Konstantin Olshansky U-402 appears to have been repainted to Russian Navy colours and given a new pennant number, and may have been used to ferry troops and vehicles to Syria.

Tragically, for the Ukrainian Navy, the Annexation has proven to be only the first costly maneuvers in a sustained Russian effort. During the 2022 Russian invasion/occupation, Russian forces have again seized many of the ships they had already returned to Ukraine after the last seizure. If reports of the aftermath of the Battle of Berdiansk February 28th, 2022, are accurate, many naval units there were captured.

Consider for a moment the bizarre careers of several ships, including the Grisha class Vinnytsia U-206, the landing ship Yuri Olefirenko U-401, and the small minesweeper Henichesk. These vessels all started as units of the navy or border guard of the Soviet Union, before mid-1990s transfer to the Ukrainian Navy. They were then seized during February 2014 in Sevastopol or the Southern Naval Base, before being released to Ukraine, where they served a further 8 years before again being captured by Russian forces in the present War. We hope that Ukraine emerges from this terrible war intact, and that, on the naval side, it is able to ditch the Russian relics and finally receives the kind of agile, light, hard-hitting, missile-equipped forces it needs to protect its sovereignty from the Russian Black Sea Fleet. We also hope that the fleet is able to participate in multi-lateral exercises and operations outside of the Black Sea, bringing the Ukrainian navy in to close interoperability with international allies.

The next Ukrainian Navy? The Turkish Navy’s TCG Burgazada F-513, is an Ada Class Corvette. The Ukrainian Government signed a deal with Turkey to deliver two of these powerful, modern ships in 2023. Current experience indicates Ukraine needs corvettes and lighter ships that can carry a potent armament of anti-ship missiles.

*For navies that started out with similar fleets, see Poland, Romania, Vietnam. The most complete list of these types is found under Russia.

**The Kuznetsov Aircraft Carrier wound up serving in China, which we explored elsewhere. The other two ships remain uncompleted at Mykolaiv, with the Slava class cruiser having been intended to join the Ukrainian Navy until the idea was shelved in the late 1990s. Some of the later ideas were to complete it for the Russians, to join the other units of the class, or modify it to suit Brazilian needs.

***Update 2024 – Vinnytsia was scuttled, reportedly by Ukrainian Forces, during June 2022 at Ochakov. Ternopil was destroyed by the Russian Navy Tarantul class corvette Ivanovets to test an antiship SS-N-22 missile 20 July 2023.

Strange Soviet Submarine Snout!

Continuing our theme of strange Soviet subs, we feature the Project 633RV / a modified variant of the NATO-designated Romeo class Diesel-Electric attack submarines. S-49/PZS-50 (Commissioned in 1961) is still in existence, up a bay in Sevastopol.

The major modifications of 1970-1972 to two Romeo boats were the addition of (conspicuous) 650mm tubes above the bows for a test Anti-Submarine Warfare missile system the RPK-7 “Veter”, while 2 of the 533mm torpedo tubes were also modified for RPK-6 “Vodopad” ASW missiles. Both these are NATO-designated SS-N-16 “Stallion.” These could be armed with an Anti-Submarine Warfare torpedo or a nuclear depth charge. The Veter had a range of roughly 100km. S-49 was reportedly decommissioned late 2019, and may become a museum boat.

S-49 docked at Pivdenna Bay, Sevastopol. The distinctive housing over the bow, for the two enlarged tubes, can be seen, whereas the rest of the submarine appears similar to other Romeo boats, accessible at the above link to our Russian submarines page.
