The Douglas A-4 Skyhawk is a single-seat subsonic carrier-capable light attack aircraft developed for the United States Navy and United States Marine Corps in the early 1950s. The delta-winged, single turbojet engined Skyhawk was designed and produced by Douglas Aircraft Company, and later by McDonnell Douglas. It was originally designated A4D under the U.S. Navy’s pre-1962 designation system.
The Skyhawk is a relatively lightweight aircraft with a maximum takeoff weight of 24,500 pounds (11,100 kg) and has a top speed of more than 670 miles per hour (1,080 km/h). The aircraft’s five hardpoints support a variety of missiles, bombs and other munitions.
