Liaoning (Varyag) Aircraft Carrier

China purchased the unfinished ex-Soviet Navy aircraft carrier Varyag from Ukraine in 1998 and the vessel was delivered to China in 2002. After receiving some extensive refurbishments at the Dalian Shipyard, the vessel was commissioned by the PLA Navy in September 2012 and renamed Liaoning. The primary role of the vessel is for training and evaluation, ahead the commission of indigenous carriers.

History

Varyag is the second hull of the Soviet Navy Project 1143.5 (Admiral Kuznetsov class) aircraft carrier. The 67,500-tonne vessel was laid down at the Nikolayev South Shipyard (formerly Shipyard 444) in Nikolayev on 6 December 1985 and was launched on 4 December 1988. In July 1990, the vessel was renamed Varyag. After the dissolution of the Soviet Union in 1991, the ownership of the vessel was transferred to Ukraine. Construction stopped by 1992 due to a lack of funding. By then, 70% of the construction had been finished. The vessel was structurally completed but without weapons, electronics, or propulsion.
China first expressed interest in purchasing Varyag in 1992 and Chinese officials inspected the vessel stationed at the dock of the Nikolayev South Shipyard. However, the two sides could not agree on the price. The unfinished Varyag remained at the dock unattended for six years. In the late 1990s, the vessel was put up for auction and it was bought by a Macau-based Chinese company for US$20 million for conversion into a floating Casino and amusement park. The contract with Ukraine prohibited the buyer from using the carrier for military purposes. Before handing the ship over, the Ukrainians removed any equipment onboard Varyag that could be used to turn the vessel into a commissionable warship.
Varyag left the dock of the Nikolayev South Shipyard in 1999, towed by several high-power tug boats. However, the Turkish government refused the vessel to pass through the Bosporus Strait on the ground that the unpowered vessel posed too much risk for other ships as well as facilities in the strait. The vessel was stationed near the strait for three years until the Chinese government intervened and handed the Turkish government US$1 million as a guarantee bond.

Varyag arrived in the Dalian Shipyard in northern China in March 2002 and was stationed there under tight security. By then it became apparent that the vessel was not going to be turned into an amusement park. Instead, it was handed to the PLA Navy for research and restoration. Along with the vessel, Ukraine also handed to China all of the vessel’s blueprints and design documents. In 2005, the vessel was moved to a dry dock in the Dalian Shipyard painted in the PLA Navy grey, with scaffoldings erected around.
The restoration work was completed in late 2006. The aircraft was then moved to another dry dock in April 2009 to install engines and other heavy equipment. System installation commenced in late 2010. By March 2011 the island of the aircraft carrier was almost complete, with painting finished and scaffolding removed.

In June 2011, the PLA Chief of Staff General Chen Bing-de confirmed that China was building an aircraft carrier, making the first official acknowledgement of the ship’s existence. On 27 July, the Chinese Ministry of National Defence announced that it was refitting a second-hand aircraft carrier for ‘scientific research, experiment, and training purposes”. The first four-day sea trial began in August, followed by a second set of trials in December.
On 25 September 2012, the aircraft carrier was officially commissioned by the PLA Navy, with a new name Liaoning and hull number 16. In November, the Ministry of National Defence confirmed that Chinese navy J-15 fighters had successfully performed touch-and-go and arrested landings on the Liaoning. Chinese press estimated that crew training would continue for 4 to 5 years before the aircraft carrier reaches its full capacity.

Aircraft

The Liaoning features a short take-off but arrested recovery (STOBAR) arrangement. Aircraft take-off is assisted by a bow ski-jump angled at 14°. The flight desk is fitted with arresting wires. Two starboard lifts carry the aircraft from the hangar to the flight deck.
The Liaoning is expected to operate 24 Shenyang J-15 (Flanker-D) multirole fighters, 4 Kamov K-31 (Helix) or Changhe Z-18 AEW helicopters, 6 Changhe Z-8 ASW helicopters, and 2 Harbin Z-9G SAR helicopters.

Weapons

The Varyag was originally to be fitted with a Granit (SS-N-9 Shipwreck) anti-ship missile system. The missile launcher was removed before the vessel was sold to China. The launcher base was removed during the refit to give a larger aircraft hangar space.
For short-range air defence, the Liaoning is fitted with four HQ-10 (FL-3000N) air-defence missile systems, each with an 18-cell missile launcher. The missile launcher is similar to the U.S. Navy RIM-116 in arrangement. Derived from the TY-90 short-range air-to-air missile, the HQ-10 is fitted with a dual passive radar-/infrared-homing seeker and has a maximum range of 9,000 m. An improved variant is reportedly fitted with an independent active infrared seeker, with a maximum range of 10,000 m.

There are also two Type 1030 close-in weapon system (CIWS), which is the 10-barrel version of the Type 730 CIWS. The weapon system has a 10-barrel 30-mm cannon, which is fed by two ammunition boxes each holding 500 rounds of ready-to-use ammunition. One magazine would typically hold armour piercing discarding sabot and the other high explosives. The empty cartridge cases are ejected forwards out of the lower part of the mount. The cannon is driven by external power, with a maximum cyclic rate of fire of 3,500~6,000 rounds/min. The cannon has a maximum range of 3,000 metres, but targets are typically engaged at a distance of 1,000~1,500 metres.

Sensors

Sensors spotted on the Liaoning include a Type 382 Sea Eagle S/C air-search radar and a set of four active electronically scanned array (AESA) radar panels. The Sea Eagle S/C radar is capable of tracking 10 targets simultaneously.

Propulsion

The Liaoning is conventionally powered, possibly using a propulsion system similar to that of the Russian Navy Kuznetsov, consisting of eight boilers and four steam turbines (50,000hp each). The vessel is fitted with four shafts with fixed-pitch propellers.
