Naval Fighters 55 - McDonnell_Douglas_A-4M_Skyhawk.pdf

INTRODUCTION The last version of the Skyhawk series to be built, the A-4M Skyhawk II, was obviously the most capable. While the original Skyhawks were designed as a lightweight delivery platform for nuclear weapons, the "Mighty Mikes" were refined into the ultimate close air support weapon to protect the "Mud Marines." With the Hughes Angle Rate Bombing System installed it was arguably the world's best close air support jet aircraft ever built. Ironically, the A-4M was the only Skyhawk version, other than the A4A, to not see combat. The A-4M first entered service in 1971 as the Vietnam War was grinding to a halt and left front line service in February 1990 prior to the Gulf War. However, foreign versions of the A-4M did see combat in the Middle East. These were the Israeli A-4Ns and the Kuwaiti A-4KUs. Marine A-4Ms stayed forward-deployed in Japan throughout their active service life in readiness for a war that never was. IN TRIBUTE TO HARRY GANN Shortly after the death of Harry Gann, the first Skyhawk book in this series, Naval Fighters Number Fifty-

One, The Douglas A-4E/F Skyhawk in Navy Service, was produced and dedicated to Harry Gann. I now offer this book in tribute to Mr. Gann's photographic zeal. Virtually all aerial photos (including all photos on the back cover) and many of the ground shots used in this volume are his. Without his professionalism this book would never had been possible.

FRONT COVER: Last Skyhawk built, A-4M 160264, during a Hughes AGM-65E Maverick test on 14 November 1979 while assigned to NAS China Lake. This aircraft was known as the "Easter Egg" because of its special paint scheme. The 2960 on the aft fuselage stands for 2,960th and last Skyhawk built.

McDONNELL DOUGLAS A-4M/N SKYHAWK II

On 17 May 1963, the Bureau of Aeronautics announced a design competition for a new light attack aircraft (VAL) that would replace the Skyhawk series of aircraft. The winner of this competition was the Vought A-7A Corsair II, which served with distinction alongside the Skyhawk throughout the conflict in South East Asia. BuAer intended to reequip both Navy and Marine A-4 squadrons with the A-7, but the demands of the Viet Nam War and the resistance to the new, more sophisticated A-7 by the Marines, postponed Marine induction of the A7 Corsair until an alternate solution was discovered. The solution was the A-4M Skyhawk made possible by the development of the Pratt & Whitney J52-P-408A engine. This new version of the J52 provided a 20% increase in thrust over previous models with no appreciable increase in fuel consumption.

WING FLAPS

The Marines' mission for the light attack (VAL) aircraft was that of short range close air support. The A-7 would cost more to purchase and maintain than an improved A-4 and

had mission capabilities far in excess of those required by the Marines. The new engine made it possible to operate from 4,000 foot runways with a full weapons load. In addition, the engine's 11,200 pound thrust rating allowed for an increase in maneuverability, rate-of-c1imb and acceleration. Initial production A-4Ms offered the following improvements: Internal and external fuel load of 1,800 gallons, maximum weapons load of 9,155 pounds, ammunition increased from 100 to 200 rounds per gun, canted refueling boom to allow installation of a wider angle target acquisition system, IFF tail antennae, square-tipped fin and rudder with increase in area, a braking parachute, Escapac 1G-3 seat, self-contained engine starter, 20kVA generator (60% increase in electrical power) and a redesigned and enlarged canopy with bullet-resistant windscreen. Continued development of the "M" over its ten year· production run led to consideration of changing the aircraft's designation to A-4Y. This of course did not happen, but the added improvements are listed below.

In Fiscal 1974, a new heads-up (HUD) cockpit arrangement was installed which featured an Elliott 546 HUD with air-to-air and air-to-ground modes. In 1977, the Hughes Angle Rate Bombing System (ARBS) was added. This enabled the Skyhawk to utilize the AGM-65E Maverick and other laser-guided weapons against hard targets. After the system/aircraft fit had been established, the ARBS system was retrofitted to all previous built A-4Ms. In its final form the A-4M had a fin tip pod with an ALR-45 homing and warning antenna and two more ALR45 antennas flanking the ARBS system in the nose. Below this in the nose were an ALQ-126 low-band antenna on the right and a mid-band ALQ-126 on the left. Also located in the nose between the two ALQ-126 antennas was an ARA-63 ILS antenna. An ALR-50 L-band antenna was added to the nose gear door. The

tion (below) are illustrated here. FIRST FLIGHT Two A-4Fs, Bureau Numbers 155042 and 155049, were converted to A-4M configuration with 155042

making the first flight on 10 April 1970. Douglas test pilot Walt Smith took off from the Douglas facility at Palmdale, CA, for a one hour check flight. Smith explored the aircraft's flight characteristics and its major systems. Most of the flight was conducted at an altitude of 30,000 feet

with the prototype M reaching a maximum speed of .9 Mach. When Smith landed he was congratulated by Major General Robert Owens Commanding General 3rd MAW (Marine Aircraft Wing) EI Toro, CA.

The first five production aircraft delivered to the Marine Corps at the McDonnell Douglas Palmdale plant on 16 April 1971. Four of the aircraft were to ferried MCAS Yuma where they were presented to LCol G. J. Ertimeier, CO of VMA-324, the first unit to receive the "M". The fifth A-4M flew to NAF Washington DC to appear in ceremonies on April 20th to honor the 2500th Skyhawk delivery. (McDonnell Douglas)

FIRST DELIVERY The first production A-4M was BuNo 158148. It was turned over to the Marine Corps in October 1970 in a ceremony at the Douglas plant. At the brief ceremony, Wellwood E. Beall, executive VP of Douglas, presented the first A-4M log books to

Capt K. B. Mattson, the Navy's plant representative at Douglas. Mattson, in turn, gave the log books to LtCol Gene Russell from the Naval Air Test Center (NATC), Patuxent River, MD. Russell then ferried the new A-4M to NATC where it took part in Navy Bureau of Inspection and Survey (BIS) trials.
