The AMX International AMX is a ground-attack aircraft for battlefield interdiction, close air support and reconnaissance missions. It was built until 1999 by AMX International, an Italian-Brazilian joint venture. The AMX is designated A-1 by the Brazilian Air Force, and A-11 Ghibli by the Italian Air Force.
The AMX is capable of operating at high subsonic speed and low altitude, by day or night, and if necessary, from bases with poorly equipped or damaged runways. Low IR signature and reduced radar equivalent cross-section help prevent detection, while low vulnerability of structure and systems aid survivability, while integrated ECM, air-to-air missiles and nose-mounted guns provide self-defence capabilities.
In early 1977, the Italian Air Force issued a requirement for 187 new-build strike fighters, which were to replace its existing Aeritalia G.91 in the close air support and reconnaissance missions, as well as the Lockheed RF-104G Starfighter also being used in the reconnaissance role. Rather than competing for the contract, Aeritalia (now Alenia Aeronautica) and Aermacchi agreed to make a joint proposal, as both firms had been considering the development of a similar class of aircraft for some years. Aermacchi had worked on a design study for a light ground attack aircraft, designated MB-340, during the early 1970s. Development work on the joint venture began in April 1978. The detailed definition phase of the project was completed in March 1980.
During 1980, the Brazilian government announced that they intended to participate in the program as a replacement for the Aermacchi MB-326. In July 1981, the Italian and Brazilian governments agreed on joint requirements for the aircraft, and Embraer was invited to join the industrial partnership. An agreement was also struck to divide AMX manufacturing between the partners; for each production aircraft, Aeritalia manufactured 46.5% of the components (central fuselage, stabilisers and rudders), Aermacchi produced 22.8% (front fuselage and tail cone), and Embraer performed 29.7% of the work (wing, air intakes, pylons and drop tanks). There was no duplication of work, each component of the aircraft was built at one source only. The planned requirements were 187 aircraft for Italy and 100 for Brazil.
A total of seven flight-capable prototypes were produced for the test program, three by Aeritalia, two by Aermacchi, and two by Embraer, as well as two static airframes. The first prototype, assembled in Italy, made its maiden flight on 15 May 1984. This first aircraft was lost on its fifth flight in an accident, resulting in the death of its pilot. Aside from this early loss, testing progressed smoothly and without further incident. The first Brazilian-assembled prototype made its first flight on 16 October 1985. On 11 May 1988, the first production aircraft performed its first flight. Deliveries of production aircraft to Italy began in 1988, the first examples were delivered to the Brazilian Air Force during the following year. On 14 March 1990, the prototype two-seat AMX made its first flight.
The AMX has a conventional shoulder-winged monoplane. It is composed primarily of aluminium and manufactured using traditional construction methods, however elements such as the tail fin and elevators use carbon fibre composite materials. The wing is fitted with both leading edge slats and trailing edge flaps and overwing spoilers ahead of the flaps. The spoilers can function as airbrakes and to negate lift; improving take-off and landing performance as well as manoeuvrability during flight. A hybrid flight control system is fitted, with spoilers, rudder and variable incidence tailplane operated by a fly-by-wire system, while the ailerons and elevators are operated hydraulically. Manual reversion is provided for the ailerons, elevator and rudder to allow the aircraft to be flown even in the event of complete hydraulic failure.
A Rolls-Royce Spey turbofan engine powers the AMX. During the aircraft's development, the Spey was heavier and less modern than some of the available alternatives, but it was considered to be reliable, relatively cheap and was free of export restrictions that would be imposed by using American engines. The Spey engine also enabled for the use of a simplified round-lipped inlet design. The rear fuselage is detachable in order to gain access to the engine. Separate consortia in both Brazil and Italy manufactured the Spey for the AMX. Unusual for a strike aircraft of the era, no attempt was made to develop the aircraft to fly at supersonic speeds.
Brazilian and Italian aircraft differ considerably in their avionics. AMXs in Brazilian service are often fitted with one of three pallet-mounted sensor packages, which contain various vertical, oblique, and forward-facing cameras. A simple ranging radar is equipped for targeting purposes, however the specific radar also differs between both operators. The flight system employs a GE Avionics flight control computer. Extensive electronic countermeasure (ECM) are fitted to protect the aircraft, include passive receiver antenna on the tailfin and an active jammer pod that is typically mounted on one of the aircraft's hardpoints.
Various munitions could be mounted on the one centerline and four under-wing hardpoints, including bombs, missiles and rockets. All four of the under-wing hardpoints are plumbed for drop tanks to extend the aircraft's range, Italian aircraft are also fitted with a fixed aerial refueling probe. Optical reconnaissance pods can be carried externally on the centerline hardpoint. Wingtip rails are provided for infrared guided air-to-air missiles such as the AIM-9 Sidewinder and MAA-1 Piranha. Italian aircraft are fitted with a M61 Vulcan 20 mm rotary cannon on the port side of the lower fuselage. The United States denied the sale of the M61 to Brazil, thus its AMXs are instead fitted with two 30 mm DEFA 554 revolver cannons.
The first operational squadron of the Italian air force, the 103° Gruppo of 51° Stormo formed in November 1989, with the first Italian unit also forming in 1989. Both the Italian and Brazilian AMX fleets were grounded in February 1992, following the crash of an Italian AMX due to engine failure. Operations were allowed to restart in May that year, following modification of the engines.
Italy assigned six AMXs from 103° Gruppo to operations over Bosnia in 1995 as part of Operation Deny Flight, which was followed by a similar deployment in support of the IFOR peacekeepers in Bosnia. This deployment was interrupted by another grounding, again due to engine failure, between January and March 1996. Italian AMX aircraft were used in 1999 in the Kosovo war. Instead of using unguided or more traditional laser-guided bombs, the Italian Air Force used dozens of Mk 82 bombs fitted with Opher Israeli guidance kits, effectively converting the "dumb" bombs into an infrared-guided bomb.
In the late 1990s, AMX International was considering a major engine refit; a non-afterburning variant of the Eurojet EJ200 was proposed, with considerably more thrust than the existing powerplant. In 2005, the Italian Air Force launched an upgrade programme (ACOL Aggionamento Capacità Operative e Logistiche – Operational and Logistical Capability Upgrade) for 55 of its AMXs, adding a new laser INS, new cockpit displays and allowing the aircraft to drop Joint Direct Attack Munition guided bombs. In August 2007, Embraer began a major midlife upgrade programme and modernisation of 53 Brazilian Air Force AMX A-1s, focusing on avionics systems and new armament additions; the programme is estimated to have extended the lifespan of the fleet beyond 2027.
Starting in November 2009, four Italian AMXs were deployed overseas for operations in Afghanistan, replacing the same number of Italian Tornado IDS in the reconaissance role. Of particular note is the aircraft's ability to share digital electro-optical and infrared sensor information with ground troops in real time, providing valuable reconnaissance information and helping to minimise threat exposure. By the end of 2010 over 700 combat missions had been flown in the Afghan theatre. On 28 May 2014, the AMX performed its last combat sortie in the Afghan theatre, and on 20 June 2014, all remaining AMXs were withdrawn from Afghanistan.
In 2011, Italian AMX aircraft were employed during the 2011 military intervention in Libya. Italian military aircraft deployed 710 guided bombs and missiles during sorties: Italian Air Force Tornados and AMX fighter bombers deployed 550 bombs and missiles, while Navy AV-8Bs deployed 160 guided bombs. AMX aircraft for the first time used Litening III targeting pods paired with Paveway and JDAM guided bombs.
As of March 2012, the Philippines was in negotiations with Italy for the possible procurement of used AMX aircraft, however on 28 March 2014, the Philippines' Department of National Defense signed a contract for 12 FA-50 light attack aircraft worth P18.9 billion (US$421.12 million).

In 1986, development of a two-seat advanced trainer variant was undertaken. This was intended to provide trainee pilots with experience on fast jets, while still retaining the single-seater's attack capabilities. First flying in 1990, the AMX-T equipped both the Italian and Brazilian air forces.
The AMX Advanced Trainer Attack (AMX-ATA) is a new AMX two-seater multi-mission attack fighter developed for combat roles and advanced training. The AMX-ATA incorporates new sensors, a forward-looking infrared helmet-mounted display, a new multi-mode radar for air-to-air and air-to-surface capability, and new weapons systems including anti-ship missiles and medium-range missiles. The Venezuelan Air Force ordered eight AMX-ATA in 1999 for the advanced trainer and attack aircraft role, but the US Congress vetoed the sale because the aircraft systems include US technology.
