Kuznetsov-class aircraft carrier

TheKuznetsov-class aircraft carrying cruiser(Russian: Авиано́сцы ти́па «Кузнецо́в»Avianо́stsii Tipa "Kuznetsо́v"), Soviet designationProject 1143.5,is a class ofSTOBARaircraft carriersoperated by theRussianandChinesenavies. Originally designed for theSoviet Navy,theKuznetsov-class ships use aski-jumpforlaunchinghigh-performancejet aircraftandarrestor gearsforlanding.The design represented a major advance in Soviet fleet aviation over theKiev-classcarriers, which do not have full-lengthflight deckand could only launchVSTOLaircraft. The Soviet Union's classification for the class was as aheavy aircraft-carrying cruiser,which permits the ships to transit the Turkish Straits without violating theMontreux Convention.[5]However, the Chinese variants are classified as aircraft carriers.

Because of thedissolution of the Soviet Unionin 1991, the threeKuznetsov-class ships were built over a protracted construction period of almost four decades. Two ships were originally laid down at theNikolayev South Shipyardin theUkrainian SSR,to be followed by the first of theUlyanovsk-classnuclear-poweredsupercarriers.Only the lead shipAdmiral Kuznetsovhad been commissioned when the Soviet Union dissolved in 1991, and the ship now serves in theRussian Navy.Construction of her sister shipVaryagwas abandoned until 1998, when an independentUkrainesold the uncompleted ship to China for use as afloating casino,along with a complete set of design blueprints. After a protractedtowedjourney through three different oceans,Varyagarrived at theDalian Shipyardand was eventually completed and commissioned in 2012 as China's first aircraft carrier, theType 001aircraft carrierLiaoning.China subsequently constructed a third ship to a modifiedType 002design, commissioningShandongin 2019.

Role

edit

TheKuznetsov-class ships were described by their Soviet builders asTyazholiy Avianesushchiy Kreyser(TAKR or TAVKR) – "heavyaircraft-carrying cruiser"– intended to support and defend strategic missile-carrying submarines, surface ships, and maritime missile-carrying aircraft of the Soviet fleet. In its fleet defense role,Admiral Kuznetsov'sP-700 Granit(SS-N-19NATO reporting name:Shipwreck) anti-ship cruise missiles,3K95 Kinzhal(Gauntlet) surface-to-air missiles, andSu-33(Flanker-D) aircraft are its main weapons. The fixed-wing aircraft onKuznetsovare intended forair superiorityoperations to protect a deployed task force. The carrier also carries numerous helicopters foranti-submarine warfare(ASW) and search and rescue (SAR) operations.

Transiting the Turkish Straits

edit
See also:Montreux Convention Regarding the Regime of the Straits § Aircraft carriers

The Russian naval system classifies itsKuznetsov-class ship as a heavyaircraft-carrying cruiserbecause it was fitted with long-range anti-ship cruise missiles. Under the 1936Montreux Convention,aircraft carriers heavier than 15,000 tons may not pass through theTurkish Straits.SinceKuznetsovexceeds thedisplacementlimit, it would have been confined to theBlack Seaif it had been classified as an aircraft carrier. However, there is no tonnage restriction on othercapital shipsoperated byBlack SeaPowers.[5]Turkey has allowedAdmiral Kuznetsovto pass through the Straits, and no other signatory to the Montreux Convention has objected to its designation as anaircraft cruiser.[6]

The Chinese Navy regards its Type 001 ships as aircraft carriers.[7] The Chinese aircraft carrierLiaoningis armed with air-defense weapons, but it is not equipped with the anti-ship or anti-submarine missiles that are onAdmiral Kuznetsov.Instead, the hangar bay was extended to carry more aircraft.[8]

History

edit
The launch ofAdmiral Kuznetsov,formerly named asLeonid Brezhnevas shown in this image

In October 1978 the Soviet government decided to continue the production of additionalProject 1143(Kiev-class) aircraft carriers, with the fifth vessel built with improved features likecatapultsand arresting gear.[9]This resulted in the Project 1143.5 (Kuznetsovclass) plan created by the Nevskoye Bureau and approved at the end of 1979. As originally planned, Project 1143.5 was to have a full load displacement of 65,000 tons,CATOBARcapability, and an air wing based around fixed-wing aircraft and Kamov helicopters.[9]However, by 1980 Soviet defense ministerDmitry Ustinovordered the deletion of the catapults, reduction of the ship's displacement by 10,000 tons, and revision of the air component towardVSTOLaircraft.[10]The design was revised to support only VSTOL aircraft under the project name "Nitka", but then was revised again to its final configuration to provide for fixed-wing aircraft by adding a 12-degreeski-jump.

Design

edit

Hull and flight deck

edit

The hull design is derived from the 1982Kievclass,[11]but is larger in both length and beam. TheKiev-class ships had only anangled flight deck,with surface weaponry on the foredeck. TheKuznetsovclass is the first Soviet carrier to be designed with a full-length flight deck. The ship's 12 anti-ship cruise missiles are located in launchers below the flight deck, just aft of the ski-jump.

The aircraft carriers are of aSTOBARconfiguration: Short Take-Off But Arrested Recovery. Short take-off is achieved by using a 12-degreeski-jumpon the bow. There is also anangled recovery deckwith arresting wires, allowing aircraft to land without interfering with launching aircraft. The flight deck has a total area of 14,700 square metres (158,000 sq ft). Two aircraft elevators, on the starboard side forward and aft of the island, move aircraft between the hangar deck and the flight deck.

Air wing

edit

In the original project specifications, the ship should be able to carry up to 33 fixed-wing aircraft and 12 helicopters.[3]The primary aircraft carried areSukhoi Su-33fighters, naval variants of theSukhoi Su-27Flanker.Kamov Ka-27naval utility helicopters (and subsequent variants) make up the helicopter wing, providing anti-submarine, maritime patrol and naval assault mobility capabilities. In addition, theKamov Ka-52K"Katran" attack helicopter, a naval variant of the Kamov Ka-50, can also be included in its air wing.

Armament

edit

TheKuznetsov-class ships were originally designed asaircraft cruisers.Kuznetsovcarried twelve launchers forP-700 Granit(SS-N-19Shipwreck) anti-ship surface-to-surface missiles, which also form the main armament of theKirov-classbattlecruisers.The Granits were stored in 12 vertical launchers located beneath the ship's front deck, just before the inclined ski-jump. The top deck hatches of these launchers open to fire the missiles; however, when open they prevent the simultaneous launch of aircraft.[12]Kuznetsov'sheavy surface armament differs from that of other countries' aircraft carriers, which carry only defensive armament and rely on their aircraft for strike power.

For long-range air defense,Kuznetsovcarries 24 verticalTor missile system(SA-N-9Gauntlet)surface-to-air missilelaunchers, with 192 missiles. For close-range air defense, the ship carries eightKashtanclose-in weapon system(CIWS) mounts. Each mount has two launchers for9M311SAMs, twinGSh-3030 mm rotary cannons, and a radar/optronic director. The ship also carries sixAK-63030 mm rotary cannons in single mounts. For defense against underwater attack, the ship carries theUDAV-1ASW rocket launcher.

The Russian Navy reportedly removed the Granit missile tubes in the late 2000s to make room for a larger hangar bay, but it was never clear that the tubes were ever actually removed. During a major overhaul set to begin in September 2017, the P-700 tubes were to be replaced with new vertical launch tubes capable of housing newerKalibrandP-800 Onikscruise missiles.[13]Air defense upgrades would include replacement of the Kashtan CIWS with thePantsir-Mand the 3K95 Kinzhal/Tor system with thePoliment-Redutsystem.[14][needs update]

Electronics

Admiral KuznetsovhasD/E bandair and surface target acquisition radar (passive electronically scanned array),F bandsurface search radar,G/H bandflight control radar,I bandnavigation radar, and fourK bandfire-control radars for the Kashtan CIWS.

The ship has hull-mounted medium- and low-frequency search and attacksonar.The ASW helicopters have surface search radar, dipping sonar, sonobuoys, and magnetic anomaly detectors.

Propulsion and performance

edit

Admiral Kuznetsovis conventionally powered bymazutfuelled steam boilers[clarification needed]which feed four steam turbines, each producing 50,000hp(37 MW), driving four shafts with fixed-pitch propellers. The maximum speed is 29 knots (54 km/h; 33 mph), and her range at maximum speed is 3,800 nautical miles (7,000 km; 4,400 mi). At 18 knots (33 km/h; 21 mph), her maximum economical range is 8,500 nautical miles (15,700 km; 9,800 mi).[citation needed]

Reliability

edit

Admiral Kuznetsovhas been plagued by years of technical problems. The vessel's steam turbines and turbo-pressurised boilers have been reported to be so unreliable that the carrier is accompanied by a large ocean-going tug whenever it deploys, in case it breaks down. There are also flaws in the water piping system, which causes it to freeze during winter. To prevent pipes from bursting, the water is turned off in most of the cabins, and half the latrines do not work.[15]

Type 001 design changes

edit

The Chinese Type 001 ships are configured as aircraft carriers. The cruise missile launchers were never installed, and the launcher base was removed during the refit to incorporate a larger hangar bay. The air-defense system consists ofFL-3000Nsurface-to-air-missiles and theType 1130 CIWS.[8][16]

Type 002 design changes

edit

Several design changes were made to the Type 002 aircraft carrier. Length, width, and displacement have been slightly increased.[17][18][19]The island of the ship has been reduced in size to increase the size of the flight deck, and it carries a3-D phased array radar.[20]The ship claims it can carry 36 aircraft instead of the 24 J-15 fighters carried byLiaoning.[21]

Admiral Flota Sovetskogo Soyuza Kuznetsovwas designed by the Neva Design Bureau, St. Petersburg, and built at theNikolayev South Shipyard(Chernomorskoye Shipyard) in theUkrainian SSR.She was launched in 1985, commissioned in 1990, and became fully operational in 1995. The vessel was namedRiga,Leonid Brezhnev,andTbilisi,[3]before finally being named after Soviet admiralNikolay Kuznetsov.

During the winter of 1995–1996,Admiral Kuznetsovdeployed to the Mediterranean Sea to mark the 300th anniversary of the Russian Navy. In late 2000,Admiral Kuznetsovwent to sea for recovery and salvage operations for the submarineKursk.In late 2007 and early 2008,Admiral Kuznetsovagain deployed to the Mediterranean. Most recently,Admiral Kuznetsovwas deployed to the Mediterranean in late 2016 and early 2017 to supportRussian operations in Syria.

Admiral Kuznetsovstarted an overhaul and modernization program in the first quarter of 2017 to extend its service life by 25 years,[23]but several setbacks have hampered this effort. Prior to a December 2022 fire the overhaul of the carrier was projected to last into 2024.[24]

As of October 2024the non-operationalAdmiral Kuznetsovis the Russian Navy's only carrier leaving the Russian Navy without an operational aircraft carrier. Reports that theAdmiral Kuznetsov's crew of 1500 has been reassigned to theRussian Armyforcombat duty in Ukrainehave fueled speculation that there is no plan to makeAdmiral Kuznetsovseaworthy again.[25]

Liaoning

The second member of theKuznetsovclass took a much more roundabout route to active service. Known first asRigaand thenVaryag,she was laid down by theNikolayev South Shipyardin 1985 and launched in 1988.Varyaghad not yet been commissioned when the Soviet Union dissolved in 1991, and the ship was left to deteriorate in the elements. In 1998, the unfinished hull was sold by Ukraine to what was apparently a Chinese travel agency for ostensible use as a floating hotel and casino.[26]After an eventful journey under tow, she arrived in China in February 2002 and was berthed at theDalian naval shipyard,where she was overhauled and completed as China's first aircraft carrier.[27][28]

In September 2012, the ship was commissioned in theChinese navyasLiaoning.[29]The ship was named after theprovincewhere the shipyard is located, and its Chinese ship class isType 001.Today, she serves as the first aircraft carrier of thePLAN,and its home port isQingdao.[28]

Shandong

The second Chinese aircraft carrier was constructed in China according to a modified design, known as Type 002. The ship was laid down in 2013 at theDalian naval shipyardand was launched on 26 April 2017. Sea trials began on 13 May 2018,[30]and the ship was commissioned asShandongon 17 December 2019.[19]
