Black Sea Fleet

Imperial Russian Navy

The Black Sea Fleet is considered to have been founded by Prince Potemkin on 13 May 1783, together with its principal base, the city of Sevastopol. Formerly commanded by admirals such as Dmitry Senyavin and Pavel Nakhimov, it is a fleet of great historical and political importance for Russia. During the Russo-Turkish War of 1787–1792 Russian control over Crimea was confirmed and Russian naval forces under the command of Admiral Fyodor Ushakov defeated the Turkish fleet at the Battle of Kerch Strait in 1790, preventing the Turks from landing a force in Crimea; while Ushakov's victory at Tendra allowed the Russians to begin the siege of Izmail, a potent Ottoman stronghold by the Black Sea, which was twice besieged without effect.

During the French Revolutionary Wars, the Black Sea Fleet was initially deployed under the command of Admiral Ushakov, in conjunction with the Turks, against French forces during the Siege of Corfu. The victory led to the establishment of the Septinsular Republic with the island of Corfu then serving as a base for Russian naval units in the Mediterranean operating against the French.

Turkey, encouraged by the French, went to war with Russia in the Russo-Turkish War of 1806–1812. The Russian fleet (deploying from the Baltic, but joining some vessels of the Black Sea Fleet already in the Mediterranean prior to the outbreak of war)^[8] under the command of Admiral Dmitry Senyavin played an instrumental role in this conflict securing victories at both the Battle of the Dardanelles (1807) and the Battle of Athos.

After the conclusion of the Napoleonic Wars, the Russians, together with the British and French, intervened in the Greek War of Independence defeating the Turkish fleet at the Battle of Navarino in 1827 and helping to secure Greek independence (though once again, the Russian fleet was compelled to deploy from the Baltic). Turkish closure of the Dardanelles Straits then sparked a renewed Russo-Turkish conflict from 1828 to 1829 which led to the Russians gaining further territory along the eastern Black Sea.

The restriction imposed on the Black Sea Fleet by Turkish control of the Straits was influential in motivating Russia from time-to-time to attempt to secure control of the passage, which became a recurrent theme in Russian policy. From 1841 onward, the Russian fleet was formally confined to the Black Sea by the London Straits Convention.^[9]

Crimean War

Within the Black Sea itself, the Turks found themselves at a naval disadvantage in relation to the Russian Black Sea Fleet. In 1853, the Black Sea Fleet destroyed Turkish naval forces at the Battle of Sinop after the Turks had declared war on Russia. Nevertheless, during the ensuing Crimean War, the Russians were placed on the defensive and the allies were able to land their forces in Crimea and, ultimately, capture Sevastopol.^[9]

As a result of the Crimean War, one provision of the 1856 Treaty of Paris was that the Black Sea was to be a demilitarized zone similar to the Island of Åland in the Baltic Sea.

1877 conflict with Turkey

This hampered the Russians during the Russo-Turkish War of 1877–1878 and in the aftermath of that conflict, Russia moved to reconstitute its naval strength and fortifications in the Black Sea.^{[citation needed]}

1905 revolution

The Black Sea Fleet would play an instrumental political role in the 1905 Russian Revolution with the crew of the battleship Potemkin revolting in 1905 soon after the Navy's defeat in the Russo-Japanese War. The revolt acquired a symbolic character in the lead up to the Russian Revolutions of 1917 and after, as portrayed in the 1925 film by Sergei Eisenstein, Battleship Potemkin. Lenin wrote that the Potemkin uprising had had a huge importance in terms of being the first attempt at creating the nucleus of a revolutionary army.^{[citation needed]}

World War I and Russian Civil War

During World War I, there were a number of encounters between the Russian and Ottoman navies in the Black Sea. The Ottomans initially had the advantage due to having under their command the German battlecruiser SMS Goeben, but after the two modern Russian dreadnoughts Imperatritsa Mariya and Imperatritsa Ekaterina Velikaya had been built in Nikolaev, the Russians took command of the sea until the Russian government collapsed in November 1917. German submarines of the Constantinople Flotilla and Turkish light forces would continue to raid and harass Russian shipping until the war's end.

In 1918, some elements of the fleet were interned by the Central Powers as a result of their advance into South Russia. In the April Crimea operation, the goal of both Ukrainians and Germans was to get control over the Black Sea Fleet, anchored in Sevastopol. Former Chief of Staff Mikhail Sablin raised the colours of the Ukrainian National Republic on 29 April 1918,^[10] and moved a portion of the Ukrainian fleet (two battleships and fourteen destroyers) to Novorossiysk in order to save it from capture by the Germans.

He was ordered to scuttle his ships by Lenin but refused to do so. Most ships returned to Sevastopol, where they first came under German control. In November 1918 they came under control of the Allies, who later gave the ships to Wrangel's fleet of the Whites.

In 1919, following the collapse of the Central Powers' occupation in Western Russia, the Red Fleet of Ukraine was established out of certain remnants of the Russian Imperial Fleet. However, subsequently these elements were either scuttled or captured by the Western Allies. During the ensuing Russian Civil War, the chaotic political and strategic situation in southern Russia permitted the intervening Western allies to occupy Odessa, Sevastopol and other centres with relative ease.

Most of the ships of the Black Sea Fleet became part of the "Russian Squadron" of Wrangel's armed forces. Following the defeat of anti-Bolshevik forces and the evacuation of Crimea by White forces, the fleet itself sailed to Tunisia. Out of those ships, some passed to the French Navy while others were sold as scrap.

Soviet Navy

With the defeat of the anti-Bolshevik Armed Forces of South Russia, the Soviet government took control of all naval elements. The few ships that remained in the Black Sea were scrapped in the 1920s and a large scale new construction programme began in the 1930s. Over 500 new ships were built^{[citation needed]} during that period and a massive expansion of coastal infrastructure took place. The Black Sea Fleet was commanded by Vice Admiral F.S. Oktyabrskiy on the outbreak of war with Germany in June 1941.

World War II

During World War II despite the scale of the German/Axis advance in southern Russia, and the capture of Crimea by Axis forces in mid-1942, the Fleet, though badly mauled, gave a creditable account of itself as it fought alongside the Red Army during the Siege of Odessa and the Battle of Sevastopol.^[11]

Soviet hospital ship Armenia was sunk on 7 November 1941 by German aircraft while evacuating civilians and wounded soldiers from Crimea. It has been estimated that approximately 5,000 to 7,000 people were killed during the sinking, making it one of the deadliest maritime disasters in history. There were only 8 survivors.^[12]

Cold War

With the end of World War II, the Soviet Union effectively dominated the Black Sea region. The Soviet Union controlled the entire north and east of the Black Sea while pro-Soviet regimes were installed in Romania and Bulgaria. As members of the Warsaw Pact, the Romanian and Bulgarian navies supplemented the strength of the Soviet Black Sea Fleet.^[13] Only Turkey remained outside the Soviet Black Sea security regime and the Soviets initially pressed for joint control of the Bosporus Straits with Turkey; a position which Turkey rejected.^[14]

In 1952, Turkey decided to join NATO, placing the Bosporus Straits in the Western sphere of influence. Nevertheless, the terms of the Montreux Convention limited NATO's options with respect to directly reinforcing Turkey's position in the Black Sea. The Soviets, in turn, had some of their naval options in the Mediterranean restricted by the Montreux Convention limitations.^[15]

In the later post-war period, along with the Northern Fleet, the Black Sea Fleet provided ships for the 5th Operational Squadron in the Mediterranean, which confronted the United States Navy during the Arab-Israeli wars, notably during the Yom Kippur War in 1973.^[16]

In 1988 Coastal Troops and Naval Aviation units of the Black Sea Fleet included:^[17]

• Danube Flotilla:
  • 116th River Ship Brigade (Izmail, Odesa Oblast)
• 112th Reconnaissance Ship Brigade (Lake Donuzlav (Mirnyy), Crimean Oblast)
• 37th Rescue Ship Brigade (Sevastopol, Crimean Oblast)
• Marine and Coastal Defense Forces Department
  • 810th Naval Infantry Brigade (Sevastopol, Crimean Oblast)
  • 362nd independent Coastal Missile Regiment (Balaklava, Crimean Oblast)
  • 138th independent Coastal Missile Regiment (Chernomorsk, Crimean Oblast)
  • 417th independent Coastal Missile Regiment (Sevastopol, Crimean Oblast)
  • 51st independent Coastal Missile Regiment (Mekenzerye, Crimean Oblast)
• Naval Air Forces Department of the Black Sea Fleet
  • 2nd Guards Maritime Missile Aviation Division (Gvardeyskoye, Crimean Oblast)(three regiments of maritime attack Tu-22M2s^[18]
    • 5th Maritime Missile Aviation Regiment (Veseloye, Crimean Oblast) – disbanded 15.11.94.
    • 124th Maritime Missile Aviation Regiment (Gvardeskoye, Crimean Oblast) – disbanded 1993.
    • 943rd Maritime Missile Aviation Regiment (Oktyabrskoye) – disbanded 1996.
  • 30th independent Maritime Reconnaissance Aviation Regiment (Saki-Novofedorovka, Crimean Oblast)(Tu-22P)
  • 318th independent Anti-Submarine Aviation Regiment (Lake Donuzlav, Crimean Oblast)
  • 78th independent Shipborne Anti-Submarine Helicopter Regiment (Lake Donuzlav, Crimean Oblast)
  • 872nd independent Shipborne Anti-Submarine Helicopter Regiment (Kacha, Crimean Oblast)
  • 917th independent Transport Aviation Regiment (Kacha, Crimean Oblast)
  • 859th Training Center for Naval Aviation (Kacha, Crimean Oblast)

In 1989, the 126th Motor Rifle Division at Simferopol was transferred to the Black Sea Fleet from the Odesa Military District. Also that year, the 119th Fighter Aviation Division, with the 86th Guards, 161st, and 841st Guards Fighter Aviation Regiments, joined the Fleet from the 5th Air Army.^[19] The 86th Guards Fighter Aviation Regiment became part of the Moldovan Air Force upon the breakup of the Soviet Union. The 841st at Meria airport (between Poti and Batumi in the Adjar ASSR) (Georgian SSR) became the 841st independent Guards Anti-Submarine Helicopter Regiment in May 1991 and was disbanded in October 1992.^[20]

The 43rd Aviation Sevastopol Red Banner Order of Kutuzov Regiment of Fighter-Bombers, after being included in the Air Force of the Red Banner Black Sea Fleet on 1 December 1990, was renamed the 43rd Separate Naval Assault Aviation Sevastopol Red Banner Order of Kutuzov Regiment.

After the fall of the Soviet Union

With the fall of the Soviet Union and the demise of the Warsaw Pact, the military importance of the fleet was degraded and it suffered significant funding cuts and the loss of its major missions.

In the early 1990s the fleet had 645 ships and 72,000 personnel.^[21]

In 1992, the major part of the personnel, armaments and coastal facilities of the Fleet fell under formal jurisdiction of the newly independent Ukraine as they were situated on Ukrainian territory. Later, the Ukrainian government ordered the establishment of its own Ukrainian Navy based on the Black Sea Fleet; several ships and ground formations declared themselves Ukrainian.

However, this immediately led to conflicts with the majority of officers who appeared to be loyal to Russia. According to pro-Ukrainian sailors they were declared "drunkards and villains" and they and their families were harassed.^[22] They have also claimed that their names were branded "traitors to Russia" on local graffiti.^[22] Simultaneously, pro-Russian separatist groups became active in the local politics of Ukraine's Autonomous Republic of Crimea and the city of Sevastopol where the major naval bases were situated, and started coordinating their efforts with pro-Moscow seamen.

During this time the Georgian Civil War broke out. Fighting erupted between two separatist minorities of South Ossetia and Abkhazia supported by Russia on one side and the Georgian government led by Zviad Gamsakhurdia on the other. However, he was ousted during the so-called Tbilisi War in 1991. The new government continued the fighting against the break-away republics, but at the same time asked Russia's president Boris Yeltsin for support against the 'Zviadists' who were trying to regain power. This led to the Black Sea Fleet landing in Georgia (despite the unsettled dispute over ownership of the fleet), and resulted in the Battle of Poti.^[23]

Joint Fleet and its partition

Presidents Leonid Kuchma of Ukraine and Boris Yeltsin of Russia negotiated terms for dividing the fleet, and to ease the tensions, on 10 June 1995 the two governments signed an interim treaty,^[24] establishing a joint Russo-Ukrainian Black Sea Fleet under bilateral command (and Soviet Navy flag) until a full-scale partition agreement could be reached. Formally, the Fleet's Commander was to be appointed by a joint order of the two countries' presidents. However, Russia still dominated the Fleet unofficially, and a Russian admiral was appointed as Commander; the majority of the fleet personnel adopted Russian citizenship. Minor tensions between the Fleet and the new Ukrainian Navy (such as electricity cut-offs and sailors' street-fighting) continued.

In 1996 the 126th Motor Rifle Division was disestablished.

Moscow mayor Yuriy Luzhkov campaigned to annex the city of Sevastopol, which housed the fleet's headquarters and main naval base, and in December the Russian Federation Council officially endorsed the claim. Spurred by these territorial claims, Ukraine proposed a "special partnership" with NATO in January 1997.^[25]

On 28 May 1997, Russia and Ukraine signed several agreements regarding the fleet including the Partition Treaty, establishing two independent national fleets and dividing armaments and bases between them.^[26] Ukraine agreed to lease major parts of its facilities to the Russian Black Sea Fleet until 2017.^[27] However, permanent tensions on the lease details continued. The Fleet's main base was still situated in the Crimean port city of Sevastopol. In 2009 the Yushchenko Ukrainian government declared that the lease would not be extended and that the fleet would have to leave Sevastopol by 2017.^[28]

Due to the lack of fleet facilities in Russia, the former naval area at the Port of Novorossiysk was revived in September 1994, and officially reorganised as Novorossiysk Naval Base in 1997.^[8] The Russian Federation planned to house the headquarters and the bulk of the fleet there, and undertook a major upgrade of Novorossiysk military facilities starting in 2005 and finishing in 2022.^{[citation needed]}

In April 2010 President Yanukovych renegotiated and extended the Russian leasehold until 2042 and an option for an additional five years until 2047 plus consideration of further renewals. This deal proved controversial in Ukraine.^{[29][30][31][32][33]} It appeared to violate the constitutional ban on basing foreign military forces, and would eventually lead to high treason charges.^{[citation needed]}

In this regard, relations between Russia and Ukraine over the status of the Fleet continued to be strained. In an August 2009 letter to Russian President Medvedev, Ukrainian President Yushchenko complained about alleged "infringements of bilateral agreements and Ukrainian legislation"^[34]

In June 2009, the head of the Security Service of Ukraine said that after 13 December 2009, all officers from the Russian Federal Security Service (FSB) represented at the Black Sea Fleet would be required to leave Ukraine. From then, the Security Service of Ukraine would ensure the security of the Black Sea Fleet, including Russian sailors on Ukrainian territory.^[35] However, according to the Russian Foreign Ministry, employees of the FSB working at the Black Sea Fleet facilities were to remain on Ukrainian territory "in line with bilateral agreements".^[36] In 2010, based on an agreement between the Ukrainian and Russian governments, military counterintelligence officers from the Federal Security Service returned to the Black Sea Fleet base.^[37]

Despite these differences, joint exercises between the Ukrainian Navy and the Black Sea Fleet of Russia resumed with a command-staff exercise in June 2010 after a seven-year interval.^[38] In May 2011, Russia and Ukraine resumed their joint "Peace Fairway" (Farvater Mira) naval exercises.^[39]

Georgia in the Fleet partition

The newly independent nation of Georgia, which also hosted several bases of the Soviet Black Sea Fleet when it was the Georgian SSR, also claimed a share of the Fleet, including 32 naval vessels formerly stationed at Georgia's Black Sea port of Poti. Not a CIS member at that time, Georgia was not, however, included in the initial negotiations in January 1992. Additionally, some low-importance bases situated in the Russian-backed breakaway autonomy of Abkhazia soon escaped any Georgian control.^[40]

In 1996, Georgia resumed its demands, and the Russian refusal to allot Georgia a portion of the ex-Soviet navy became another bone of contention in the progressively deteriorating Georgian-Russian relations. This time, Ukraine endorsed Tbilisi's claims, turning over several patrol boats to the Georgian Navy and starting to train Georgian crews, but was unable to include in the final fleet deal a transfer of the formerly Poti-based vessels to Georgia.^[40] Later, the rest of the Georgian share was decided to be ceded to Russia in return for diminution of debt.

Russia employed part of the fleet during the 2008 Georgian conflict. Russian units operating off Georgia's breakaway Abkhazia region resulted in a reported skirmish and sinking of a ship of the Georgian Navy. Since the 2008 South Ossetia war the Russian Black Sea Fleet has not taken part in any joint naval exercises involving Georgian warships.^[41] However, such a statement has little meaning since the Georgian Navy has ceased to exist (early 2009 it was merged with the Georgian coast guard).^[42]

Russo-Ukrainian War

Russian annexation of Crimea

The 2014 political crisis in Ukraine rapidly engulfed Crimea where pro-Russian separatist sentiment was strong.^{[43][44][better source needed]} When the Russian Government determined to seize Crimea, specialist Russian military units appear to have played the central role. In March, the Ukrainians claimed that units of the 18th Motor Rifle Brigade, 31st Air Assault Brigade and 22nd Spetsnaz Brigade were deployed and operating in Crimea, instead of Black Sea Fleet personnel, which violated international agreements signed by Ukraine and Russia.^[45][46] Nevertheless, at minimum the Black Sea Fleet played a supporting role including with respect to preventing the departure of Ukrainian naval vessels from Crimea.^[47] Other sources suggested that the 810th Naval Infantry Brigade of the Fleet was also involved.^[48]

After the 2014 Crimean crisis, the Ukrainian Armed Forces and the Ukrainian Navy were evicted from their bases and subsequently withdrew from Crimea.^[49] During the occupation, Russian forces seized 54 out of 67 ships of the Ukrainian Navy.^{[50][unreliable source]} According to sources from Black Sea Fleet Headquarters, inspections of all ships were to be done by the end of 2014.^{[51][better source needed]} On 8 April 2014 an agreement was reached between Russia and Ukraine to return Ukrainian Navy materials to Ukraine proper.^[52] The greater portion of the Ukrainian naval ships and vessels were then returned to Ukraine but Russia suspended this process after Ukraine did not renew its unilaterally declared ceasefire on 1 July 2014 in the conflict in the Donbas.^[53] According to the fleet commander Aleksandr Vitko, this happened because the vessels were old "and, if used [by Ukraine], could hurt its own people".^[54]

Crimea was then formally annexted into Russia through a referendum, but this was declared invalid by United Nations General Assembly Resolution 68/262.^[55]

Strengthening the fleet

From that point, Russia proceeded to consolidate its military position in Crimea, which it now regards as an integral part of the Russian Federation, though this position is not one supported by the vast majority of the international community. The Russian seizure of Crimea in 2014 changed the situation and role of the Black Sea Fleet significantly. Analysis undertaken by Micheal Peterson of the US Naval War College suggested that since the Russian seizure of Crimea, the modernization of Russian shore-based assets and of the Black Sea Fleet itself assisted in re-establishing Russian military dominance in the region. Specifically Peterson argued in 2019: "Russian maritime dominance in the Black Sea is back. The shift was made possible by Moscow's 2014 seizure of Crimea and subsequent buildup of combat and maritime law enforcement capabilities in the region".^[56]

Prior to the annexation of Crimea,^[when?] divergent announcements had been made concerning the future composition of the fleet. In June 2010, Russian Navy Commander-in-Chief Admiral Vladimir Vysotsky announced that Russia was reviewing plans for the naval modernization of the Black Sea Fleet. The plans include 15 new warships and submarines by 2020.^{[citation needed]} These vessels were to partially replace the reported decommissioning of Kerch, Ochakov (decommissioned in 2011 and sunk as a blockship in 2014), several large support ships, and a diesel-electric submarine. Also in 2010, Russian Navy Headquarters sources projected that, by 2020, six frigates of the Project 22350 Admiral Gorshkov class, six submarines of Project 677 Lada class, two large landing ships of Project 11711 Ivan Gren class and four class-unspecified ships would be delivered. Due to the obsolescence of the Beriev Be-12 by 2015, they were planned to be replaced with Il-38s. Sukhoi Su-24M aircraft were planned to be upgraded to Su-24M2 at the same time.^{[57][58][59][needs update]}

Since the annexation of Crimea, the composition of the Black Sea Fleet shifted focus to the Improved Kilo-class submarines instead of the Lada, the Admiral Grigorovich-class frigates and at least three new classes of missile corvettes (the Steregushchiy, Karakurt and Buyan-M classes). The deployment of the Admiral Gorshkov-class frigate with the Black Sea Fleet was still anticipated, though in reduced numbers.^[60] The replacement of the Black Sea Fleet's Soviet-era missile boats and corvettes with vessels of more modern design had been a priority since 2010. A similar modernization is also taking place in the Baltic Fleet and the Caspian Flotilla. Utilizing Russia's internal waterways provides the Russian Navy with the capacity to transfer both corvettes and other light units, such as landing craft, among its three western fleets and the Caspian Flotilla as may be required.^[61] Analysis in May 2022 suggested that it might be feasible for the Russian Navy even to move its Kilo-class submarines between the Black Sea and the Baltic via the internal waterways.^[62]

The projection of power into the Mediterranean also returned^[when?] as a significant role for the Black Sea Fleet with the creation of the Russian Navy's permanent task force in the Mediterranean. Both the Black Sea Fleet and the Caspian Flotilla have supported Russian involvement in the Syrian Civil War with units from the former now routinely deployed into the Mediterranean.^[63][64][65] The deployment of submarines from the Black Sea Fleet to the Mediterranean has become^[when?] a routine occurrence (though the need to send them for "maintenance" in the Baltic, so as to comply with terms of the Montreux Convention, lengthens the timeframe of such deployments significantly).^{[66][full citation needed]} In late 2021 it was reported that one of the new Priboy-class helicopter assault ships, the Mitrofan Moskalenko, had been earmarked to enter service with the Black Sea Fleet "within the next few years" in the role of fleet flagship.^[67] If confirmed such a deployment would significantly enhance the fleet's power projection capabilities.^{[according to whom?]}

Also significant is the build-up of Russian surface-to-surface and surface-to-air missile assets in the region. Dmitry Gorenburg of the Centre for Naval Analysis (CNA) has noted in 2018 that: "Russia's expanded military footprint in Crimea allows it to carry out a range of operations that it was not capable of prior to 2014. The deployment of S-400, Bastion, and Bal missiles allows the Russian military to establish an anti-access/area denial zone (A2/AD) covering almost all of the Black Sea. By using a combination of ground-based and ship-based missiles, backed with strong electronic warfare capabilities, the Russian military can inhibit military movement into the Black Sea and deny freedom of action to an opponent if it does make it into the theater. The long-range sea-, air-, and ground-launched missiles deny access, while shorter-range coastal and air defense systems focus on the area denial mission. The result is several interlocking air defense zones".^[68]

As of 2020^[update], ongoing technological upgrades of this already robust SAM network were planned during the 2020s.^[69] Others, such as Michael Kofman of CNA, argued in 2019 that while there is no A2/AD doctrine or term in Russian military strategy, Russian forces nevertheless are organized at an operational and strategic level to deploy a wide range of overlapping defensive and offensive capabilities that extend beyond just one theatre of operations like the Black Sea.^[70]

The evident American response to the dense shore-based anti-ship and air defence capabilities that Russia has developed in the Black Sea region, and elsewhere, has been to place greater emphasis on striking at potential Black Sea and other targets utilizing stand-off air-launched cruise missiles deployed on American long-range bombers.^[71] Additionally, the United States, the United Kingdom and Turkey have entered into contracts to supply new corvettes, missile-armed fast attack craft, patrol boats and unmanned air vehicles to the Ukrainian Navy.^[72]

In 2020, the Black Sea Fleet obtained seven new warships and auxiliary ships, including corvette Grayvoron, patrol ship Pavel Derzhavin, seagoing tug Sergey Balk, as well as a harbour tugs and three hydrographic survey vessels. In 2021, Russian sources said that the same number of vessels should enter service.^{[73][needs update]}

Russo-Ukrainian naval standoff

On 29 January 2021, three US naval vessels entered the Black Sea for the first time in three years.^[74] On 1 February, the Ukrainian president Volodymyr Zelensky argued for NATO membership for Ukraine.^[75] On 19 March, another significant US naval deployment to the Black Sea took place, as cruiser USS Monterey and destroyer USS Thomas Hudner entered the sea on 19 and 20 March respectively.^[76][77] Prior to the scheduled deployment, on 12 March Russian cruiser Moskva made an exit to sea and on 19 March all six submarines of the Black Sea Fleet went to sea, which was an unprecedented event.^[78][79]

Russian ground forces also started a buildup on the border with Ukraine. On 2 April, Zelensky had his first telephone conversation with Biden, and on 6 April he called NATO's Secretary-General Jens Stoltenberg pressuring NATO to speed up Ukrainian path to the membership.^[80] On 8 April, Russia started moving ten of its Caspian Flotilla warships to the Black Sea. Six amphibious and three artillery boats of Serna and Shmel classes, as well as a hydrographic boat GS-599, were reported in transit, while Black Sea Fleet frigate Admiral Essen conducted an artillery exercise, usually done to raise the readiness for the amphibious landing.^{[81][82][83][84][85]} The same day, the US decided to send two warships to the Black Sea.^[86]

On 9 April 2021, tensions rose further and Ukraine promised not to attack the separatists, while Russia considered intervening.^[87][88] On the same day, two Black Sea Fleet corvettes, Vishny Volochyok and Gravoron, conducted an exercise.^[89] The two US destroyers were clarified by Turkey to be USS Roosevelt and USS Donald Cook, while Putin stressed the importance of the Montreux Convention in a telephone conversation with Turkish president Recep Erdogan.^[90][91] On 14 April, the deployment of the two US destroyers was cancelled.^[92] On 17 April, amphibious ships Aleksandr Otrakovsky and Kondoponga of the Northern Fleet and Kaliningrad and Korolyov of the Baltic Fleet strengthened the amphibious warfare capabilities of the Black Sea Fleet.^[93] On 30 April, the cruiser Moskva fired a Vulkan anti-ship missile for the first time.^[94]

In November, further tensions started amidst the build-up of Russian ground forces on the Ukraine border. On 2 November, the destroyer USS Porter^[95] entered the Black Sea, followed on 25 November by the destroyer USS Arleigh Burke.^[96] In late October, the Russian Black Sea fleet held a large exercise with a cruiser, a frigate and three corvettes.^[97]

Incident with HMS Defender

On 23 June 2021, the United Kingdom's HMS Defender undertook a freedom of navigation patrol through the disputed waters around the Crimean Peninsula.^[98] The Ministry of Defence of the Russian Federation and border guards said they fired warning shots from coast guard patrol ships and dropped bombs from a Sukhoi Su-24 attack aircraft in the path of Defender after, according to the Russian Defence Ministry, it had allegedly strayed for about 20 minutes as far as 3 km (2 miles) into waters off the coast of Crimea, which Russia annexed in 2014 in a move mostly unrecognised internationally.^[99][100] The UK military denied any warning shots were fired and said the ship was in innocent passage in Ukraine's territorial sea, later clarifying that heavy guns were fired three miles astern and could not be considered to be warning shots.^{[101][102][103]}

2022 Russian invasion of Ukraine

A build-up of Russian forces around Ukraine and in Belarus began toward the end of 2021, ostensibly for exercises. In February 2022, the Black Sea Fleet was reinforced by six landing ships: three Ropucha-class landing ships (Minsk (127), Korolev (130) and Kaliningrad (102)) were drawn from the Baltic Fleet while two (Georgy Pobedonosets (016) and Olenegorsky Gornyak (012)) came from the Northern Fleet. The Ivan Gren-class landing ship, Pyotr Morgunov (117) also deployed to the Black Sea from the Northern Fleet.^[104] The 22nd Army Corps (subordinate to the Black Sea Fleet) was also reinforced, including by the 247th Regiment of the 7th Guards Mountain Air Assault Division as well as by the 56th Guards Air Assault Regiment, subordinate to the same division.^[105] On the eve of the conflict, it was reported that the headquarters of the 58th Combined Arms Army had deployed to Crimea commanding between 12 and 17 battalion tactical groups.^[106][107]

The Russian invasion of Ukraine began on 24 February 2022 and it was initially reported that this included an amphibious landing at Odesa by elements of Russian Naval Infantry and the Black Sea Fleet.^[108] However, the report of a landing at Odesa on 24 February subsequently proved to be false.^[109] On 24 February 2022, the cruiser Moskva and the patrol ship Vasily Bykov bombarded Snake Island in the Danube Delta and captured it from its Ukrainian garrison.^[110] On 26 February 2022 it was reported that Russian forces made an amphibious assault at Mariupol utilizing half of their landing ships in the Black Sea. A second Russian amphibious group was said still to be positioned in the vicinity of Odesa.^[111]

On 28 February 2022, Turkey indicated that it was closing the Dardanelles Straits to all foreign warships for the duration of the conflict. Turkish Foreign Minister Mevlüt Çavuşoğlu argued that the move was consistent with terms of the Montreux Convention. An exception would be allowed for Russian ships returning from the Mediterranean to Black Sea bases where they were registered.^[112][113]

As of early March 2022, the Ukrainian navy was confirmed to have lost two vessels: the frigate Hetman Sahaidachny, scuttled by its crew to avoid capture,^[114] and the patrol vessel Sloviansk, reported sunk by Russian action on 3 March 2022.^[115] On 7 March 2022 it was reported that the Russian patrol ship Vasily Bykov may have been damaged by Ukrainian shore-based multiple-launch rocket fire.^[116] However, the ship was subsequently reported as having entered Sevastopol on 16 March 2022 with no obvious damage.^[117]

On 14 March 2022, the Russian source RT reported that the Russian Armed Forces had captured about a dozen Ukrainian ships in Berdiansk. The vessels reported as captured included two Gyurza-M-class artillery boats (including Akkerman), the Matka-class missile boat Pryluky, a Project 1124P (Grisha II)-class corvette (likely an already decommissioned vessel given the absence of active ships of this class in the Ukrainian navy), a Zhuk-class patrol boat, a Yevgenya-class minesweeper, the Polnocny-class landing ship Yuri Olefirenko and a Ondatra-class landing craft.^[118]

The 43rd Guards Naval Assault Aviation Regiment traces its history to the 43rd Fighter Aviation Regiment (ru:43-й истребительный авиационный полк). The regiment began its formation in May 1938 and was finally formed on 11 or 13 May 1938 in the Kiev Special Military District at Vasylkiv airfield from the 71st, 5th and 109th separate fighter aviation squadrons.^[314] It joined the 51st Aviation Brigade of the Air Forces of the Kiev Special Military District.

The regiment's first commander from summer 1938 was Vladimir Sryvkin (ru:Срывкин, Владимир Алексеевич).^[315] Major Sryvkin handed over command in 1939 and became assistant commander of the 72nd Fighter Aviation Brigade. In May 1944, he died of wounds received in action.

On 22 June 1941, the regiment was still located at Vasylkiv, forming part of the 36th Fighter Aviation Division of the Air Defence Forces of the Kiev Special Military District.^[316]

Over the entire period of its existence, the regiment was repeatedly reorganized and changed its name depending on the honorary titles assigned, awards and changes in the type of aviation:

The 43rd Fighter Aviation Regiment on 9 June 1942 was reorganized into the 43rd Mixed Aviation Regiment. The 43rd Mixed Aviation Regiment was reorganized on 21 June 1942 into the 43rd Fighter Aviation Regiment.[3]

The 43rd Fighter Aviation Sevastopol Red Banner Order of Kutuzov Regiment on 1 April 1960 was renamed the 43rd Aviation Sevastopol Red Banner Order of Kutuzov Regiment of Fighter-Bombers (APIB).

The 43rd Aviation Sevastopol Red Banner Order of Kutuzov Regiment of Fighter-Bombers, after being included in the Air Force of the Red Banner Black Sea Fleet on 1 December 1990, was renamed the 43rd Separate Naval Assault Aviation Sevastopol Red Banner Order of Kutuzov Regiment.

In connection with the reduction of the Russian Air Force, the 43rd Separate Marine Assault Aviation Sevastopol Red Banner Order of Kutuzov Regiment was reorganized on 1 October 1995 into the 43rd Separate Marine Assault Aviation Sevastopol Red Banner Order of Kutuzov Squadron.

In December 2004, the squadron was upgraded to a regiment once again. The 43rd separate naval assault aviation Sevastopol Red Banner Order of Kutuzov Regiment in connection with the ongoing reform of the RF Armed Forces in 2009 was renamed the 7058th Aviation Sevastopol Red Banner Order of Kutuzov Naval Aviation Base of the Russian Federation.

The 43rd separate naval assault aviation Sevastopol Red Banner Order of Kutuzov Naval Aviation Regiment of the Black Sea Fleet of the Russian Federation was re-formed in 2014 at the Novofedorovka airfield near the city of Saki.

The regiment was part of the "active army" (in front-line combat service) for six periods between 22 July 1941 and 9 May 1945.^[317]

The Russian Black Sea Fleet's (BSF) use of leased facilities in Sevastopol and the Crimea was sometimes controversial. A number of incidents took place:

• For security reasons, the BSF refused to allow Ukrainians to inspect its aircraft cargo, after allegations by Ukrainians that they could be carrying nuclear weapons, which would have infringed upon Ukraine's status under the Nuclear Non-Proliferation Treaty (NPT)^[34]
• The BSF transported rockets repeatedly through the port of Sevastopol without seeking permission from Ukrainian authorities.^[34]
• A lighthouse is located on the headland which, starting in 2005, was the subject of a controversy between Ukraine and Russia. From 3 August 2005, the lighthouse was occupied by the Russian military.^[318] Despite a controversial ruling by a Court in Sevastopol on the subject, Russian military officials referred to the fact that they only took orders from the chief of the Russian Navy headquarters and no one else. Ukrainian activists complained that Sarych was illegally occupied by the Russian Navy.^[319] As a military facility, the territory around the Sarych headland is closed to trespassers with barbed wire, and the Russian flag flew over Sarych.^[320]
• In 2006, Ukrainian officials blocked Russian workers from entering the BSF lighthouse in Yalta.^{[citation needed]}
• During the 2008 South Ossetia War, the Ukrainian Navy was ordered to block the entrance to Sevastopol from Russian vessels taking part in the hostilities.^{[citation needed]} However, Russian Navy ships returned to base unimpeded by the sympathetic Ukrainian sailors.^{[citation needed]}
• 20 June 2009 – In Sevastopol, a Russian fleet servicemen allegedly used physical force against 30 civilians. The city also alleges contract violations by the Construction Management Corporation of the Black Sea Fleet for not following through on promises to construct requested commercial housing after taking advance payment. The city began talks with the President and the Prime-Minister of the Russian Federation, Dmitry Medvedev and Vladimir Putin, and also to the Russian Minister of Defense Anatoliy Serdyukov with respect to the contract violations, but those did not yield results.^[321]
• On 27 August 2009, Russian marines successfully prevented Ukrainian bailiffs from enforcing a Ukrainian court ruling on seizing lighthouses belonging to the BSF.^[34] Russia stated that Ukrainians may not step onto its bases without permission.^{[citation needed]} The Ukrainian Foreign Ministry described the Russian obstruction as a "disregard for Ukrainian legislation and international agreements".^[34]
• On 16 April 2013, a "high-ranking Russian Defense Ministry official" complained to Interfax that "Ukraine's stubborn position" was slowing the cancellation of customs payments (for the fleet) and that Ukraine still upheld (former) Ukrainian President Viktor Yushchenko's 2008 decrees that banned the "relaxed procedure" of BSF formations crossing the Ukrainian border.^[322]
• In the late hours of 13 April 2022 Ukrainian presidential adviser Oleksiy Arestovych reported Moskva was on fire and Odesa governor Maksym Marchenko said their forces hit Moskva with two R-360 Neptune anti-ship missiles.^[323]
• On 22 September 2023, Ukraine hit the headquarters of the BSF using a Storm Shadow missile, killing at least 6 people.^[324]
• on 1 February 2024, Ukraine released video purported to show the sinking of the Tarantul-class vessel Ivanovets by unmanned surface vehicle.^[325][326]
• On 5 March 2024, the Sergey Kotov patrol vessel was sunk using Magura V5 naval drone.^[327]
• On 23 March 2024, The defense forces of Ukraine hit the Russian large amphibious Ropucha-class landing ships Yamal. According to Ukraine's military intelligence, the 'yamal' warship suffered critical damage: a hole in the upper deck caused it to roll to the starboard side.^[328]
