The A-4M was specifically developed for the US Marines, and 160 were built. It has a more powerful engine, more ammunition for its cannon, and improved systems over those of earlier Skyhawks. It is the latest model of Skyhawk produced, and is still used by the USMC (though it is being replaced by the AV-8B), the Israelis, and the instructors at "Top Gun" to simulate MiGs. [See also A-4F]
