The Marine Corps’ most recent acquisition, the A-4M Skyhawk has recently completed Service Acceptance Trials at NATC, Albuquerque and Pt. Mugu. Major changes from earlier Skyhawk models include an improved J52 engine with a 20% increase in thrust, a drag chute, a larger canopy, and a 100% increase in ammunition capacity. A self-contained starter is currently under development. During the Trails, the A-4M completed 48 hours of sustained operations without a major material discrepancy. In comparison with its predecessor, the A-4F, the “M” reduced take-off distance 16%, increased maximum airspeed by 5%, and added approximately 2000 feet to the Skyhawk’s combat ceiling. Rate of climb, acceleration, and sustained maneuverability were also noticeably increased, especially at combat loadings. The higher thrust combined with the drag chute provides for an unassisted shortfield capability in close air support operations. Follow-on tests will include accelerated service trials and technical evaluation for complete performance information.
