The A-4M Skyhawk, flown by Marine Attack Squadron 311 (VMA-311), represented the ultimate refinement of the Douglas A-4 series, purpose-built for U.S. Marine Corps ground-attack operations. Introduced in the early 1970s, the A-4M featured substantial improvements in engine power, avionics, survivability, and pilot ergonomics, making it the most advanced Skyhawk variant ever produced.

Driven by a Pratt & Whitney J52-P-408 turbojet engine, the A-4M boasted improved thrust, offering a top speed of approximately 673 mph (1,083 km/h). Its robust design allowed for a maximum ordnance load of 9,900 lbs (4,490 kg) across five external hardpoints, enabling it to carry a wide array of bombs, rockets, and missiles—including the AGM-45A Shrike anti-radiation missile.

VMA-311, nicknamed the "Tomcats", effectively deployed the A-4M in both training and operational contexts, particularly in close air support and strike missions. The squadron’s proficiency combined with the Skyhawk’s nimble performance helped define U.S. Marine air-ground tactics in the late Cold War period.

Key features and upgrades of the A-4M included:

Dorsal avionics "hump" housing advanced electronics and navigation systems.

Upgraded cockpit with a heads-up display (HUD), enlarged canopy, and improved ejection seat.

Enhanced survivability, including increased armor and countermeasure systems.

More powerful engine for improved climb rate and payload performance.
