After World War II ended, the Soviets were left with the hulls of unfinished Sovetsky Soyuz-class battleships of Project 23 and didn't know what to do with them, as building the ships under the initial project had already been deemed pointless. One possible solution was to finish the ships as aircraft carriers—the suggested project was codenamed 23AV. That solution could have been implemented in the U.S.S.R. between the end of the 1940s and the beginning of the 1950s. However, the top leadership of the U.S.S.R. didn't find the project compelling, so the hulls of the Project 23 battleships were eventually scrapped for metal.
