The project was codenamed Eagle (Орёл), just like the two earlier helicopter and aircraft cruiser projects, and several projects of other classes of ships, were named after birds of prey. However the carriers themselves were named after Soviet cities, while only frigates were named after birds (see Russian ship naming conventions); the actual projected name of the ships is not known.
The Project 1153 (itself based on an early-1970s Project 1160, confusingly also named Orel, even 10,000 tonnes heavier) was cancelled in October 1978 as being too expensive, and a smaller Project 1143.5, more V/STOL-aircraft-oriented, was developed instead: in its initial stage, a version of 65,000 tons and 52 aircraft was proposed, but the actual Kuznetsov-class aircraft carriers are even smaller, about 55,000 tons.[2] While the Project Orel never saw fruition, in the 1980s it influenced the also abortive Ulyanovsk program.
