Douglas A-4 Skyhawk This plane is a Navy and Marine aircraft. The A-4 Skyhawk was the jet that the A-6 Intruder was designed from. You can see some of the similair features right off. It has the same air intakes, similair canopys, ect. The A-4 was made in a contest to meet certain standards. They were very high, so some thought it impossible. Then, Douglas made it and got chosen to have their planes mass produced. It was good for it's time, but went out eventually. Then, the A-6 took over.
