A-4 Skyhawk

The Marine Corps A-4 Skyhawk is a lightweight, single engine attack aircraft. The mission of an A-4 attack squadron is to attack and to destroy surface targets in support of the landing force commander, escort helicopters, and conduct other operations as directed. Developed in the early 1950s, the A-4 Skyhawk was originally designated the A-4D as a lightweight, daylight only nuclear capable strike aircraft for use in large numbers from aircraft carriers. There are numerous models of the A-4 in use. The A-4M and the TA-4F are currently used by Marine Corps Reserve squadrons. All models have two internally mounted 20mm (.8 inch) cannons, and are capable of delivering conventional and nuclear weapons under day and night visual meteorological conditions. The A-4M uses a heads-up display and computer aided delivery of its bomb load with the angle rate bombing system. The Marine Reserve has two squadrons of A-4s with 12 aircraft each. Additionally, each squadron has two TA-4 aircraft.
