I've read in a few places that there were a couple of proposals (one from the US and another by the French after the war's end) to turn the unfinished French battleship Jean Bart into an aircraft carrier (which were obviously refused). Tzoli seems to have made a mockup of how it might've looked...
Expected into service in ~2032. 16 SLBMs, 14,500 tons surfaced.
