A-4 E/F/G Skyhawk

The E (of which 499 were made) and F (of which 147 were made) represent the first real upgrade in airplanes, with a more potent engine, two extra mooring towers for cargo (for a total of five) and improved avionics. They were used extensively, and with excellent results, during Americas war in Vietnam..The A-4 owes its origins to a desire expressed by the US Navy for a replacement of the A-1 Skyraider. The engineering design genius Ed Heinemann created a super lightweight and simple airplane which was pressed into service on American aircraft carriers in 1956.
