The list of aircraft carriers of the Soviet Union and Russia includes all aircraft carriers built by, proposed for, or in service with the naval forces of either the Soviet Union or Russia. Although listed as aircraft carriers, none of them (with the exception of the never-built Ulyanovsk) have been classed as a "true" aircraft carrier (supercarrier). Specifically, they were all ASW helicopter carriers or aircraft cruisers, including the Admiral Kuznetsov, the only carrier still in service with the Russian Navy. Russia is currently considering building a supercarrier, code-named Project Shtorm. All completed aircraft carriers of the Soviet and later Russian navy have been built at Ukrainian shipyards in the city of Mykolaiv.
