Ulyanovsk (Cyrillic: Улья́новск), officially known as Project 1143.7 Ulyanovsk in the Union of Soviet Socialist Republics of the Soviet Union, are a class of Soviet supercarriers, which began construction in the late 1980s, with the lead ship Ulyanovsk being laid down in 1988. Project 1143.7 Ulyanovsk was the first true class of nuclear-powered supercarriers to be built for the Soviet Navy (the others are Project 1160 Eagle and Project 1153 Eagle).

The Ulyanovsk-class supercarriers are among the largest capital ships to ever be built by the Union of Soviet Socialist Republics of the Soviet Union.

Four known supercarriers in the class are the lead ship Ulyanovsk and its sister ships Potemkin, Sverdlovsk and Kremlin.

The Ulyanovsk-class supercarriers were succeeded by Project 1143.8 Comrade Stanislav and Project 23000E Shtorm, two designs based on the Ulyanovsk-class supercarriers but much larger than Ulyanovsk.


The Ulyanovsk class aircraft carrier or Project 1143.7 Ulyanovsk was the first of a class of Soviet nuclear-powered supercarriers which would have offered true blue water aviation capability for the Soviet Navy. This was based upon the 1975 Project 1153 Eagle (which was planned and nine supercarriers were built) and the initial commissioned name was to be Kremlin, but was later given the name Ulyanovsk after the Soviet town of Ulyanovsk, which was in turn named after Vladimir Lenin's original name (Ulyanovsk's sister ships were named Kremlin, Sverdlovsk and Potemkin).

It would have been 85,000-90,000 tons in displacement (more than the older Forrestal-class but smaller than contemporary Nimitz- and Gerald R. Ford-classes of the United States Navy). The lead ship Ulyanovsk would have been able to carry the full range of fixed-wing carrier aircraft, as opposed to the limited scope in which Admiral of the Fleet of the Soviet Union Flota Sovetskogo Soyuza Kuznetsov launched aircraft, by way of a ski jump. The configuration would have been very similar to U.S. Navy carriers though with the typical Soviet practice of adding anti-ship missile (ASM) and surface-to-air missile (SAM) launchers. Its hull was laid down in 1988, launched in 1993 and fully operational and commissioned in 1995. Its followers, Potemkin, Sverdlovsk and Kremlin, were laid down in 1990, 1995 and 2000, launched in 1995, 2000 and 2005, and commissioned and fully operational in 2000, 2005 and 2010.

Air group[]

The Project 1143.7 Ulyanovsk includes 70 aircraft. It was planned following composition:

  • Fighter Sukhoi Su-27K - 24 pcs.
  • Fighter Mikoyan-Gurevich MiG-29K - 24 pcs.
  • AEW aircraft Yakovelv Yak-44RLD - 4 pcs.
  • Anti-submarine helicopter Kamov Ka-27 - 16 pcs.
  • Search and rescue helicopter Kamov Ka-27PS - 2 pcs.

The ship was equipped with two steam catapults "Lighthouse", created by the Proletarian factory , a springboard and 4 arresting gear . For storage of aircraft at the hangar deck had a size of 175 × 32 × 7,9 m on the flight deck of the aircraft rose by 3 lifts with carrying capacity of 50 tons (two on the starboard side and one on the left). In the stern of the optical system is housed landing "Moon".
