Happy 60th Birthday A-4 Skyhawk! Close to NZ's heart

22 June : Sixty years ago today, the McDonnell Douglas A-4 Skyhawk took flight for the first time. 

 A classic of Naval Aviation, the A-4 was an extraordinary aircraft.  The legendary Ed Heinemann created the Skyhawk at one-half of the weight allowed and the type remained in production for over 20 years.  The A-4 became the most impressive conventional bomber of its era, flying like a fighter but capable of bombing targets with great accuracy.  

The Skyhawk was so small that it did not require folding wings for use aboard aircraft carriers.  Skyhawks were the US Navy’s primary light bomber during the early years of the Vietnam War, carrying-out some of the first air strikes during the conflict.  On May 1, 1967, an A-4 became a MiG-killer when Lieutenant Commander Ted Swartz downed a MiG-17 with air-to-ground rockets!  A total of 2,960 Skyhawks were manufactured in a number of variants.  

Significant numbers were exported to other nations and Argentina, Israel, and Kuwait have all employed the A-4 in combat.  The Blue Angels flight demonstration squadron operated the A-4 from 1974 through 1986.  The Navy Strike Fighter Tactics Instructor program used the A-4 in an adversary role and the TA-4J model served as the advanced jet trainer until being replaced by the T-45 Goshawk.  The aircraft was affectionately known as “Heinemann’s Hot Rod” and the “Scooter.”

The Douglas A-4 Skyhawk is a carrier-capable attack aircraft developed for the United States Navy and United States Marine Corps. The delta winged, single-engined Skyhawk was designed and produced by Douglas Aircraft Company, and later by McDonnell Douglas. It was originally designated A4D under the U.S. Navy's pre-1962 designation system.

The Skyhawk is a lightweight aircraft with a maximum takeoff weight of 24,500 pounds (11,100 kg) and has a top speed of more than 600 miles per hour (970 km/h). The aircraft's five hardpoints support a variety of missiles, bombs and other munitions and were capable of delivering nuclear weapons using a low altitude bombing system and a "loft" delivery technique. The A-4 was originally powered by the Wright J65 turbojet engine; from the A-4E onwards, the Pratt & Whitney J52 was used.

Skyhawks played key roles in the Vietnam War, the Yom Kippur War, and the Falklands War. Fifty years after the aircraft's first flight, some of the nearly 3,000 produced remain in service with several air arms around the world, including from the Brazilian Navy's aircraft carrier, São Paulo.

Skyhawks were the U.S. Navy's primary light attack aircraft used over North Vietnam during the early years of the Vietnam War; they were later supplanted by the A-7 Corsair II in the U.S. Navy light attack role. Skyhawks carried out some of the first air strikes by the US during the conflict, and a Marine Skyhawk is believed to have dropped the last American bombs on the country. Notable naval aviators who flew the Skyhawk included Lieutenant Commanders Everett Alvarez, Jr. and John McCain, and Commander James Stockdale. On 1 May 1967, an A-4C Skyhawk piloted by Lieutenant Commander Theodore R. Swartz of VA-76 aboard the carrier USS Bon Homme Richard, shot down a North Vietnamese Air Force MiG-17 with an unguided Zuni rocket as the Skyhawk's only air-to-air victory of the Vietnam War.

From 1956 on, Navy Skyhawks were the first aircraft to be deployed outside of the U.S. armed with the AIM-9 Sidewinder. On strike missions, which was the Skyhawk's normal role, the air-to-air armament was for self-defense purposes.

In the early to mid-1960s, standard U.S. Navy A-4B Skyhawk squadrons were assigned to provide daytime fighter protection for anti-submarine warfare aircraft operating from some Essex-class U.S. anti-submarine warfare carriers, these aircraft retained their ground- and sea-attack capabilities. The A-4B model did not have an air-to-air radar, and it required visual identification of targets and guidance from either ships in the fleet or an airborne Grumman E-1 Tracer AEW aircraft. Lightweight and safer to land on smaller decks, Skyhawks would later also play a similar role flying from Australian, Argentinean, and Brazilian upgraded World War II surplus light ASW carriers, which were also unable to operate most large modern fighters.Primary air-to-air armament consisted of the internal 20 mm (.79 in) Colt cannons and ability to carry an AIM-9 Sidewinder missile on both underwing hardpoints, later additions of two more underwing hardpoints on some aircraft made for a total capacity of four AAMs.

Vietnam Experience:
 The first combat loss of an A-4 occurred on 5 August 1964, when Lieutenant junior grade Alvarez, of VA-144 aboard the USS Constellation, was shot down while attacking enemy torpedo boats in North Vietnam. Alvarez safely ejected after being hit by anti-aircraft artillery (AAA) fire, and became the first US Naval POW of the war; he was released from being a POW on 12 February 1973. 

The last A-4 loss in the Vietnam War occurred on 26 September 1972, when USMC pilot Captain James P. Walsh, USMC of VMA-211, flying from his land base at Bien Hoa Air Base, South Vietnam, was hit by ground fire near An Lộc. An Lộc was one of the few remaining hotly contested areas during this time period, and Captain Walsh was providing close air support (CAS) for ground troops in contact (land battle/fire fight) when his A-4 was hit, catching fire, forcing him to eject. Rescue units were sent, but the SAR helicopter was damaged by enemy ground fire, and forced to withdraw. Captain Walsh, after safely ejecting, had landed within NVA (North Vietnamese Army) positions, and had become a POW as soon as his feet had touched the ground. Captain Walsh was the last U.S. Marine to be taken prisoner during the war, and was also released from being a POW on 12 February 1973.

Although the first A-4Es were flown in Vietnam in early 1965, the A-4Cs continued to be used until late 1970. The Seabees of MCB-10 went ashore on 7 May 1965. On 1 June 1965, the Chu Lai Short Airfield for Tactical Support (SATS) was officially opened with the arrival of eight A-4 Skyhawks from Cubi Point, Philippine Islands. The group landed with the aid of arresting cables, refueled and took off with the aid of JATO, with fuel and bombs to support Marine combat units. The Skyhawks were from Marine Attack Squadron VMA-225 and VMA-311.

On 29 July 1967, the aircraft carrier USS Forrestal was conducting combat operations in the Gulf of Tonkin during the Vietnam War. A Zuni rocket misfired, striking an external tank on an A-4. Fuel from the leaking tank caught fire, creating a massive conflagration that burned for hours, killing 134 sailors, and injuring 161. 

During the war, 362 A-4/TA-4F Skyhawks were lost due to all causes. The U.S. Navy lost 271 A-4s, the U.S. Marine Corps lost 81 A-4s and 10 TA-4Fs. A total of 32 A-4s were lost to surface-to-air missiles (SAMs), and one A-4 was lost in aerial combat to a MiG-17 on 25 April 1967.

Royal New Zealand Airforce:
In 1970, 14 A-4K aircraft were delivered to the Royal New Zealand Air Force. These were later joined by 10 A-4G Skyhawks from the Royal Australian Navy in 1984; all were converted to A-4K Kahu standard.

The RNZAF withdrew the Skyhawks from service in 2001 and put them in storage awaiting sale. Draken International signed an agreement with the New Zealand government in 2012 to purchase eight A-4Ks and associated equipment for its adversary training services. The buy was later increased to 11 A-4Ks. These were subsequently relocated to the U.S. at Draken's Lakeland Linder Regional Airport facility in Lakeland, Florida. The other A-4K aircraft were given to museums in New Zealand and Australia or sold to individuals or organisation.
The New Zealand Government has not replaced the Skyhawks.

The first of the Royal New Zealand Air Force’s former Skyhawk fleet being disassembled at Woodbourne, near Blenheim, as part of the Government’s decision to place some of the aircraft in museums around New Zealand.

NZ6254, a two-seat TA-4K Skyhawk, has had its protective coating removed and was dismantled into its major components ready for movement by Defence Force transport to the Air Force Museum of New Zealand at Wigram, Christchurch, the birthplace of New Zealand military aviation.

The Museum was very keen to acquire NZ6254 as it was the first Skyhawk to fly in New Zealand following delivery in May 1970 aboard the USS Okinawa. It was also one of two Skyhawks to undertake test-firing of the Maverick air-to-surface missile in 1989, the other aircraft being NZ6205, a single-seat model, which has also been allocated to the Museum. Both aircraft were the prototypes for Project Kahu which resulted in the aircraft fleet receiving a major upgrade to their avionics.

NZ6254 was reassembled at the Museum by the Unit and went on display soon afterwards so that visitors can get the opportunity of seeing the aircraft at close quarters.

Happier days for NZ6205

Aussie Mirage III's: The Mirage III O

Being a long-time Mirage fan, I was (pleasantly) surprised to learn that Austalia, like South Africa had operated and built Mirages under licence from Dassault in France

A3 Dassault Mirage III

The search for a Sabre replacement began in the 1950s, and when a joint evaluation team from the Departments of Air and Supply visited Europe and North America in 1960, the Dassault Mirage III emerged as their selection over the Lockheed F-104 Starfighter.

Built by the French firm Generale Aeronautique Marcel Dassault (GAMD), the Mirage I flew on 25 June 1955, followed the following year by the prototype Mirage III. Having selected the Mirage, the RAAF then had to decide on the power plant, and with the Rolls Royce Avon already in service powering both the Sabre and the Canberra, this option was pursued for the Mirage. A French Mirage IIIA, known as 'City of Hobart', was fitted with an RB146 Avon 67 turbojet and flew on 13 February 1961. This was known as a Mirage IIIO, but did not receive a RAAF serial number as, although this modification delivered superior performance, its cost was prohibitive and this project was discontinued.

Having selected the French SNECMA Atar 9C engine, the first RAAF aircraft, numbered A3-1, flew at Bordeaux on 14 March 1963 and was handed over to the RAAF at Villaroche, near Paris, on 9 April. This definitive IIIO was similar to the French Air Force Mirage IIIE. While A3-1 was flown to Australia by Hercules, the second French-built aircraft, A3-2, remained in France until August 1965 to test the various RAAF modifications. Meanwhile, two further aircraft were shipped to Australia as fully-equipped major assemblies and completed at Avalon by the Government Aircraft Factories (GAF), the Australian prime contractor. The first of these, A3-3, was flown by Squadron Leader (later Air Vice Marshal) Bill Collings at Avalon on 16 November 1963.

Gradually the French content was reduced, with GAF subcontracting the wings, tail and engine to the Commonwealth Aircraft Corporation (CAC), and by aircraft A3-16 the first Australian-built primary parts were incorporated. The first order in December 1960 for 30 aircraft, A3-1 to A3-30, was followed in 1962 by an order for a further 30, A3-31 to A3-60. In 1963 the order was increased by another 40, A3-61 to A3-100, followed by 10 two-seat trainers, similar to the French Mirage IIIB, and designated IIID, A3-101 to A3-110.

Following the two French aircraft, the first 48 Australian-assembled aircraft (A3-3 to A3-50) were built as Mirage IIIO(F) interceptors and No 2 Operational Conversion Unit (2OCU) at Williamtown began receiving deliveries in 1964. No 75 Squadron became the first operational unit to equip in 1965 followed by No 76 Squadron in 1966. The next 50 aircraft (A3-51 to A3-100) were built as IIIO(A) ground attack variants with slightly different radar and the addition of doppler navigation and radar altimeters for low-level operation.

In 1967 No 75 Squadron deployed to Malaysia to replace No 3 Squadron. No 3 Squadron then became the first unit to equip with the ground-attack Mirage under Wing Commander Jake Newham, who was later to be Chief of Air Staff. When No 3 Squadron returned to Butterworth in 1969, No 77 Squadron re-equipped and became the fourth RAAF Mirage squadron.

The first two-seater Mirage IIID, A3-101, flew on 6 October 1966 and was accepted by the RAAF at Avalon on 10 November, followed by a further nine over the next year. The trainer version did not have the Cyrano II nose radar; a second cockpit was added behind the first and the avionics equipment previously stored there was relocated in the nose. The Mirage trainers were assembled by GAF from imported French-built fuselages and CAC-built wings and vertical tail surfaces.

In December 1970 the government approved the procurement of six additional Mirage IIID trainers at a cost of $11 million. These aircraft, A3-111 to A3-116, delivered from August 1973 to January 1974, enabled the retirement of the Sabre from operational fighter training.

An anomaly in Mirage deliveries occurred with A3-26. This aircraft was retained in France by Dassault from 1965 to 1968 as a trials installation for the IIIO(A) standard. The aircraft was finally delivered to 2OCU in November 1968 and the following June it was decided to convert the remaining IIIO(F) aircraft to the IIIO(A) standard for the ground-attack role.

With defence cuts under the Whitlam Government, No 76 Squadron was disbanded amongst much ill feeling in August 1973. The remaining three squadrons continued operating the Mirage in air defence and ground attack, based at Williamtown and Butterworth. Several Mirage aerobatic teams were also formed during its service with No 77 Squadron. Best known were the Deltas in 1971, followed by the Miracles in 1976 and a three-aircraft team of red, white and blue aircraft organised for the 1981 air shows. Basing of aircraft extended to Darwin in 1983 when No 75 Squadron relocated from Butterworth.

As 2OCU began to work up for the F/A-18 Hornet in 1984, all Williamtown-based Mirages were transferred to No 77 Squadron, with some 40 of the type on strength. This must have made No 77 Squadron the largest fighter squadron ever in the RAAF. No 77 Squadron finally relinquished their Mirages for Hornets in November 1987. In March 1986 No 79 Squadron reformed at Butterworth from No 3 Squadron, as the latter began conversion to the Hornet. No 79 Squadron operated the Mirage until disbanding in April 1988, leaving No 75 Squadron at Darwin and Aircraft Research and Development Unit (ARDU) at Edinburgh as the remaining operators. In early September 1988, No 75 Squadron flew a formation of Mirages over the east coast state capitals as a farewell gesture before the aircraft ceased squadron operations on 30 September. In October the remaining No 75 Squadron Mirages were ferried to Woomera and so, appropriately, this squadron, which was the first to equip with the Mirage in 1966, was the last to operate it.

The last RAAF Mirage flight was on 8 February 1989 when A3-101 was flown from ARDU at Edinburgh to Woomera to join 47 of the type in storage pending their disposal. In 1990 Pakistan purchased fifty RAAF Mirages, including two which had been stored at Point Cook, and these have now been delivered to the Pakistan Air Force, where some will undoubtedly fly for many years to come.

The Mirage saw longer service in the RAAF front line than any other fighter. Despite the original estimated design fatigue life of only 1500 hours, some Australian Mirages flew over 4000 hours. Over forty aircraft were lost in flying accidents, but those who flew it held the type in high regard. Although the 'Miracle' has left our skies, many examples remain on display at museums around Australia.

Dassault Mirage III A3-92

Selected to replace the Avon Sabre as the RAAF's fighter aircraft in 1960, the Mirage was the first aircraft in RAAF service capable of flying at twice the speed of sound. Entering operational service during 1965, the Mirage served as the front-line fighter until 1988, making the aircraft the longest-serving fighter in RAAF history. Built under licence in Australia by the Government Aircraft Factories (GAF), 100 single-seat and 16 two-seat Mirages were operated by seven RAAF units.

The first Australian-assembled Mirage flew at Avalon airfield in March 1963, and this and the following 48 aircraft were built as Mirage IIIO(F) interceptors. Following aircraft A3-50, production switched to the Mirage IIIO(A) ground attack aircraft with slightly different equipment for this role. In June 1969, the IIIO(F) aircraft were modified to the ground attack standard, to increase commonality within the Mirage fleet.

Now a gate guard at RAAF Wagga Wagga

             
In RAAF service, the Mirage operated with Nos 3, 75, 76, 77 and 79 Squadrons, as well as No 2 Operational Conversion Unit and the Aircraft Research and Development Unit, from bases across Australia and also at Butterworth in Malaysia. With the acquisition of the F/A-18 Hornet in 1985, the Mirage was phased out of service, and in October 1988 the last Mirages of No 75 Squadron were ferried to Woomera for eventual disposal.

After the cessation of Mirage operations, a number of aircraft were retained by the RAAF as training aids. This aircraft, A3-92, was one such aircraft and was used at the RAAF School of Technical Training at Wagga Wagga before transfer to the RAAF Museum for preservation.

Delivered from the GAF airfield at Avalon, Victoria, on 26 July 1968, A3-92 served with Nos 3 and 79 Squadrons at Butterworth, Malaysia, and No 77 Squadron at Williamtown, New South Wales. Withdrawn from service in May 1987, the total airframe time for the aircraft was 4037 hours.
