Ussr AirCarrier
In April 1945, the scientific and technical committee filed an offer to the Soviet Naval Shipbuilding Bureau to finalize the construction of Kronshtadt-class heavy cruisers under Project 69I as aircraft carriers because building the ships under the initial project had already become pointless. It was intended for the ship to carry 76 airplanes. The project was codenamed 69AV. The offer wasn't implemented because the completion ratio of the hulls and associated hardware was low.
