The A-4 Skyhawk was designed by Douglas  in response to a U.S. Navy call for a jet-powered attack aircraft to replace the older A-1 Skyraider. Douglas opted for a design that would minimize its size, weight, and complexity. The result was an aircraft that weighed only half of the Navy's weight specification. It had a wing so compact that it did not need to be folded for carrier stowage. 

      A-4M: Dedicated Marine version with improved avionics and more powerful J52-P-408a engine with 11,200 lbf (50 kN) thrust, enlarged cockpit, IFF system. Later fitted with Hughes AN/ASB-19 Angle Rate Bombing System (ARBS) with TV and laser spot tracker, 158 built.


Hi,
I ship within the EU. It is impossible to list all the costs for the different countries. 
If its is less than the 15€ that I mentioned, I will refund the difference. If it is more, bad luck for me.
Mind that these costs are without track and trace. If you want that, I will have to charge you more. No problem if you then decide not to buy it. I will cancel the transaction.
If outside the EU, contact me first.
I had a small business with perfect score/feedback but I retired from that.
Now I just buy and sell as a private person.
