I wonder if some steam could be added coming from the slot of the catapult. That would be so cool...

The only thing missing now would be some actors and tractors on the CV deck .... any ideas?

The steam catapult was invented by the British and first tested in 1950, it's introduction into use occurred in the mid-1950's. Catapults used in WW II and Korea were hydraulic.
