I hope this answer isn't too long winded for you but here goes. Shortly after this mock up was built the side intakes were replaced by a chin intake
(the Typhoon intake of today is almost the same but with the curvature of the P.120 intake - see end of post). This became known as the ACA (agile
At this time the ACA was the proposed international version but BAe were insistent that the earlier P.110 could be made more quickly and cheaply as a
go it alone project which would sell well internationally as its projected in service date of 1988 (that was maybe a little on the optimistic side but
it definitely would have been a decade ahead of Typhoon anyway) would give it a head start on the new generation of US fighters. However the political
will at the time was for collaborative projects despite the obvious fact that this wouls entail delay and additional expense. Rather ironic when you
hear HMG bleating about the expense of the Typhoon nowadays
Agreement was however reached with Germany and Italy on a collaborative fighter with which to follow up the Tornado and this meant that the P.110 had
to be shelved and so BAe began to re-engineer the ACA into a low cost demonstrator that would employ the FBW systems and composite wing and canard of
the ACA but would use Tornado parts such as the rear fuselage, undercarriage and modified fin in order to keep the costs of this demonstrator down. It
was launched as a UK only research aircraft in the hope that Germany would fund a second example, however it was not to be.
The demonstrator was called the EAP, which stands for the rather uninspiring 'Experimental Aircraft Programme' and when it flew the test pilot was
reported to have commented (in his enthusiasm for the aircrafts handling and performance) "Forget the Eurofighter, I wish we could put this in
service right now, its amazing".
Throughout Typhoons development the ghost of the AFVG haunted Bae who had been left high and dry when the French unilaterally cancelled that project
and so a purely British version of the aircraft tailored exactly to the RAF's needs was always kept in reserve should the unthinkable happen, this
was called the P.120 and ironically the final Typhoon design that we know today looks exactly like it in almost every detail.
