Development of the A-4 Skyhawk began in the early 1950s, after the U.S. Navy issued a set of specifications for a potential successor to the AD Skyraider. Douglas, being the manufacturer of the proven Skyraider, received the order to come up with a new jet-powered replacement, also capable of carrying nuclear ordnance.

Taking up the task, Douglas developed the requested replacement within 2 years of the order coming in, and by doing so, developed an aircraft that was well under the allocated budget for the project and went well above the minimum requirements set out by specifications. The first prototype of the Skyhawk took to the skies in June 1954.

Highly impressed by the aircraft’s capabilities, relative simplicity and cost-effectiveness, the U.S. Navy officials didn’t wait long to sign the first production orders. As a result, the first A-4 Skyhawk production models rolled off the assembly lines in 1956 and entered official service with the U.S. Navy and USMC.

Already by the time the first production units were being completed, Douglas finished work on an improved variant of the Skyhawk - the A-4B. Among other changes and improvements, the B model of the Skyhawk allowed the aircraft to carry more sophisticated weapon systems, such as the AIM-9B Sidewinder AAMs as well as the AGM-12 Bullpup missiles.

In total, close to 3,000 A-4 Skyhawks were produced, participating in numerous conflicts, such as the Lebanese Crisis of 1958, the Vietnam War during the 1960s as well as in the Falklands War in 1982 under Argentine colors. The Skyhawks served for nearly five decades before being retired from U.S. service in the late 1990s and early 2000s, although the A-4 is still in limited use, being used as a mock aircraft, mimicking the MiG-17, for example.
