That has got to be the smalles fuel tanker/ container ship I've seen in a while. I worked at a container yard in Houston for a while and let me tell you, it should be VERY easy to converte a full size container ship to an aircraft carrier capable of launching. The cargo holds on container ships are basically huge gaping holes in the deck - which really lends itself to lift installations for aircraft. Ok, it won't carry 80 aircraft, but I think it's safe to say that with one of the super tankers or container ships, you should be able to field at least 20 aircraft.
Novel idea, nonetheless...
