It was designed to research technologies to be used for a future European combat aircraft, and eventually formed the basis for the multinational Eurofighter Typhoon.
A technology demonstration aircraft, the British Aerospace EAP, first took flight on 6 August 1986; the first prototype of the finalised Eurofighter made its first flight on 27 March 1994.

During the 1982 Farnborough Airshow, a mockup of the ACA was publicly exhibited; this mockup also appeared at the Paris Air Show in May 1983.
The American Space Shuttle Enterprise was flown around Paris and towered over other exhibits, but "much more intriguing" were replicas of two twin-engined fighters, the British Aerospace ACA and French Dassault Breguet ACX.

Power was provided by a pair of Turbo-Union RB199-104 afterburning turbofans, previously used as the Tornado's powerplant.
The engine was also used in the EAP Demonstrator assembled at, and flown from, Warton in Lancashire, England, and the early prototype Eurofighter Typhoon aircraft, both types without thrust reversers.

On 8 August 1986, after multiple delays due to unfavourable weather conditions, the EAP conducted its maiden flight, flown by BAe’s Executive Director of Flight Operations David Eagles.
He piloted the British Aerospace EAP, fore-runner of the Typhoon (ZF534) on its first flight on 8 August 1986, exceeding Mach 1.

During the 1982 Farnborough Airshow, a mockup of the ACA was publicly exhibited; this mockup also appeared at the Paris Air Show in May 1983.
At the 1986 show were demonstrated the BAe EAP, the Eurofighter predecessor, and Dassault Rafale rival fighters, as an A300 fly-by-wire testbed flying at very high angles of attack shown the wind-shear stall protection capabilities, later equipping the A320.

West Germany

Upon the announcement of the EAP during October 1983, it was intended to be a multinational European effort; however, neither West Germany or Italy would ultimately contribute financially, thus the programme relied upon a combination of British public and private funding instead. It is known that ACA had involved the combining of several years of private venture research conducted by BAe, costed at around £25 million, together with similar contemporary studies that had been performed by West German aircraft manufacturer Messerschmitt-Bölkow-Blohm (MBB) (such as the TKF-90 project) and Italian aviation company Aeritalia.

On 8 August 1986, after multiple delays due to unfavourable weather conditions, the EAP conducted its maiden flight, flown by BAe’s Executive Director of Flight Operations David Eagles. Performing its maiden flight on 8 August 1986, the EAP would fly over 250 sorties prior to its grounding on 1 May 1991, by which point the aircraft had fulfilled its intended purpose as a development aid.

Seeking to develop a new generation of fighter aircraft to equip the various air forces of Western Europe, the three companies had recognised the benefits of cooperation and the sharing of critical technologies to achieve this goal.

Fly-by-wire

Technologies which became central to the ACA included full-authority digital fly-by-wire controls, which would enable a significantly aerodynamically unstable aircraft to be flown, and multiple advanced manufacturing processes.

Early on, the British Government announced that it would make a financial contribution to the EAP; however, funding would not prove to be forthcoming from the West German government, which heavily contributed to the decision to cancel the planned second airframe prior to major work commencing.
