Design and development

In September 1972, Aermacchi was awarded a contract to study a replacement for the Italian Air Force)'s MB-326s, comparing seven all-new designs (given the designation MB-338) powered by various engineswith an improved version of the MB-326, designated the MB-339. The MB-339 was considered to meet the Italian Air Forces requirements while being cheaper than the all-new designs which resulted in it being selected to replace both the MB-326 and the Fiat G.91T in Italian service.[1]

The MB-339 is of conventional configuration and all-metal construction, and shares much of the 326's airframe. It has a low, un-swept wing with tip tanks and jet intakes in the roots, tricycle undercarriage, and accommodation for the student and instructor in tandem. The most significant revision was a redesign of the forward fuselage to raise the instructor's seat to allow visibility over and past the student pilot's head. The aircraft was fitted with a larger fin and powerplant for the initial versions was the same Rolls-Royce Viper 632-43, producing 4,000 lbf (17.79 kW), as fitted to the MB-326-K.[2]

The first flight took place on 12 August 1976 and deliveries to the Italian Air Force commenced in 1979.[3] Still in production in 2004 in an enhanced version with a much-modernised cockpit. Over 200 MB-339s have been built, with roughly half of them going to the Italian Air Force.

The Lockheed-Aermacchi MB-339 T-Bird II was a losing contender in the USA's Joint Primary Aircraft Training System (JPATS) aircraft selection. Among the seven to enter, the Raytheon/Pilatus entry won, which became the T-6 Texan II.

According to an article posted on the Italian website 'Il Porto Franci', called 'Armi e finanziamenti nel corno d'Africa', Eritrea paid about $US 50 million for six MB-339 CEs in 1997. This is the original MB-339 with more advanced avionics for the ground attack role, RWR, uprated Viper 680-43 engine, and larger wingtip tanks. It is capable of carrying Sidewinder AAMs, AGM-65 Maverick AGMs, and laser-guided bombs. Unit price of the MB-339C would have to be somewhere around $US 8.3 million in 1997 dollars.

Operational history

Argentina

Argentine Naval Aviation MB-339

The Argentine Naval Aviation (Comando de Aviación Naval) was the first foreign user of the forerunner MB-326GB, buying eight in 1969.

In 1980, Comando de la Aviación Naval Argentina (CANA), or Argentine naval air command, ordered ten MB-339As, advanced trainer and light attack aircraft. The MB339 were delivered in 1981 and were operated by the III Escuadra Naval 's 1 Escuadrilla de Ataque.[4] During the Falklands War, late in April 1982, six of them were located at Port Stanley Airport, renamed Base Aérea Militar (BAM) Malvinas.[4] They were the only attack jets to operate from the Falklands, along with four Beech T-34 Mentor piston-engined armament trainer and light attack aircraft, and 24 turboprop FMA IA 58 Pucará light attack aircraft of Grupo 3 de Ataque.[5] Other Airmacchis operated from three mainland bases, at Almirante Zar, Bahia Blanca and Río Grande, Tierra del Fuego naval air station.[6]

On 21 May during a routine reconnaissance flight and flown by Lieutenant Owen Crippa, a MB-339A was the first one to attack the Royal Navy amphibious force. The Aermacchi hit the frigate HMS Argonaut, causing light damage.[7][8] On 27 May, a MB-339A (4-A-114) was shot down by a Blowpipe missile during the Battle for Goose Green, while attempting to attack British ships and landed troops. The Pilot, Teniente (Lt) Miguel, was killed.[9][10] Three MB-339 airframes were captured by the British.[11]

Eritrea

During tensions between Eritrea and Ethiopia in the late 1990's, Eritrea started to rebuild its air force. In 1995-1996, the Eritreans ordered six Aermacchi MB.339FD strike fighters, with which the first combat unit of the ERAF was founded in 1997. They have proved their worth as training aircraft and even during the early fighting in 1998.

Their initial deployment started on 5 June 1998 (the same day in which the ETAF also started its operations). During the same afternoon, the Ethiopians reported two attacks of Eritrean MB.339FDs on the city of Mekelle, the capital of Ethiopian province Tigray. Reportedly, as many as 44 civilians were killed and 135 injured.

However, on 6 June one of the Macchis was shot down north of Mekelle. The pilot ejected and was rescued by a Mi-8 of the ERAF. The Eritrean Macchis were deployed again on the next day during the fighting around Erde Mattios.

On the morning of 12 June 1998, two Eritrean Mi-8 appeared in low level over Addis Pharmaceutical works, in Adigrat, attempting to bomb it. Their weapons, however, fell a few yards from the plant and caused only minor damage. Only a couple of hours later, four MB.339s rocketed and cluster-bombed against several targets in the city as well. According to Ethiopian sources four people died and 30 other were injured during those attacks.

On 5 February 1999 the Ethiopian government claimed that two Eritrean MB.339FDs attacked a fuel depot in Adigrat, some 48 kilometres inside the Ethiopian border, important for the supply of the Ethiopian army with fuel.
