The air groups on a carrier require specialized training to take off and land on the carrier.
The Israelis have no crews to man the ships and while the Israelis may have pilots capable of learning to take off and land on a flight deck, they do not possess that expertise today. The training issues would probably take close to 10 years to fix if they started right now. And that assumes Israel could divert sufficient qualified personnel from the rest of their armed forces.
And just running down the Stars and Stripes on a few carriers and running up the Israeli Naval Ensign, and painting Israeli stars on some Navy planes, while American sailors and aviators continue to actually man the carriers and the planes, will fool no one.
Ten years eh? Well, whatever time it normally takes, I bet israel could do it in half.
But I don’t really think israel needs aircraft carriers right away. They could get by with cruise missles and drone planes on naval vessels for now.
But by all means, start the carrier training today.
