ukVaryag Aircraft Carrier: From Soviet Heavy Cruiser to China’s First Carrier
The Project 1143.5 heavy aircraft-carrying cruiser Varyag became one of the most dramatic warship transformations of the late 20th century. Laid down in the USSR, transferred to Ukraine, sold to China, and later commissioned as Liaoning, the vessel symbolizes geopolitical shifts and the evolution of modern naval power.
Origins of Project 1143.5 and Construction of “Riga”
The heavy aircraft-carrying cruiser (TAKR) Project 1143.5 was laid down in 1985 at the Black Sea Shipyard in Mykolaiv under the name Riga. On June 19, 1990, shortly after launching, she was renamed Varyag.
In Soviet naval doctrine, the term “heavy aircraft-carrying cruiser” reflected a hybrid concept. Unlike Western aircraft carriers, these ships combined fixed-wing aviation capabilities with heavy missile armament, including anti-ship cruise missiles. This dual-role design allowed classification as cruisers rather than pure carriers, partially bypassing certain legal restrictions under the Montreux Convention.
By 1992, the ship was approximately 70% complete when construction halted due to the collapse of the USSR and severe financial constraints.
From Soviet Warship to Chinese Flagship
Transfer to Ukraine and Sale to China

After the dissolution of the Soviet Union, Varyag became Ukrainian property in 1993. On June 30, 1993, she was officially removed from the naval registry and transferred to the Black Sea Shipyard.
Unable to complete the vessel, Ukraine sold it in 1998 to a Chinese company, officially for conversion into a floating casino. However, geopolitical observers quickly understood that China intended to rebuild and commission the ship as its first aircraft carrier.
The Dramatic Tow to Asia
Soviet-built aircraft carrier Varyag transported to China without propulsion
The journey to China was anything but smooth. For nearly 18 months, Turkey refused passage through the Bosporus, citing safety concerns. Only in November 2001 was the unpowered hull allowed through.
During towing operations in the Aegean Sea, a storm caused the towlines to snap, nearly resulting in the ship being abandoned. The incident highlighted the enormous logistical complexity of relocating a 58,500-ton unfinished warship across continents.
Technical Specifications of Varyag (Project 1143.5)
| Parameter | Specification |
|---|---|
| Full displacement | 58,500 tons |
| Length | 302.3 m |
| Beam | 72.3 m |
| Draft | 9.1 m |
| Propulsion | 4 steam turbines (4 × 50,000 hp) |
| Boilers | 8 |
| Shafts | 4 |
| Maximum speed | 29 knots |
| Range | 8,500 nautical miles |
| Endurance | 45 days |
| Crew | 1,960 personnel |
| Officers | 55 |
| Air personnel | 626 |
The propulsion system was conventional steam turbine machinery, typical for late-Soviet large surface combatants. Unlike nuclear-powered carriers, this limited operational endurance but simplified engineering complexity.
Sister Ships and Design Evolution
The only completed sister ship of Project 1143.5 is the aircraft carrier Admiral Flota Sovetskogo Soyuza Kuznetsov.
Earlier related vessels include Project 1143A carriers such as:
Their conceptual predecessor was Project 1123, including:
- Moskva
- Leningrad
These ships demonstrate the gradual Soviet transition from helicopter anti-submarine cruisers to full-scale ski-jump aircraft carriers.
Final Transformation: From Varyag to Liaoning
After extensive reconstruction in Dalian, China officially commissioned the ship in 2012 as Liaoning.
Originally expected to enter service around 2010, the process required deep structural modernization, installation of new radar systems, flight control technologies, and adaptation for J-15 carrier-based fighters.
The vessel now serves as a training and operational platform for the People’s Liberation Army Navy (PLAN), marking China’s entry into blue-water carrier operations.
FAQ
Was Varyag ever commissioned by the Soviet Navy?
No. Construction stopped at roughly 70% completion and the ship never entered Soviet service.
Why was it called a “heavy aircraft-carrying cruiser”?
Because it combined carrier aviation with heavy missile armament, fitting Soviet naval doctrine and certain legal classifications.
Did China build the ship from scratch?
No. China completed and modernized the unfinished hull before commissioning it as Liaoning.
Why was passage through the Bosporus delayed?
Turkey cited navigational safety concerns due to the vessel’s size and lack of propulsion.
Conclusion
The story of Varyag reflects more than naval engineering—it mirrors geopolitical transformation. From a Soviet heavy aircraft-carrying cruiser to China’s first operational aircraft carrier, the ship embodies strategic adaptation and maritime ambition.
For researchers of naval history, aircraft carrier development, and global shipbuilding evolution, the Varyag/Liaoning case remains one of the most compelling examples of how unfinished steel can reshape international naval balance.
