AMX International AMX ground-attack aircraft Italian-Brazilian joint venture

The AMX International AMX is a ground-attack aircraft for battlefield interdiction, close air support and reconnaissance bmissions. 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.

Upgraded cockpit

Future FAB A-1M will have roughly a panel similar to the F-5M. Much of the current analogue dials will be replaced with MFD (Multi-Function Displays) colored.

Adding to the area of the three MFD, the A-1M will have about 121 square inches of area showing digital information ranging from data engine related to weapons. In addition to the new panel the A-1M will feature a HMD that will bring greater situational awareness. Source defesabrasil

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.
