Ooops missed out the source for thwe !.5 Mach claim

"Much is currently being made about supercruise, that is the ability
to cruise supersonically without the use of reheat (afterburn) for
extended periods of time. Although never stated explicitly (as for
example with the U.S. F-22) the Typhoon is capable of and has
demonstrated such an ability since early in its flight program
according to all the Eurofighter partnets. Initial comments indicated
that, with a typical air to air combat load the aircraft was capable
of cruising at M1.2 at altitude (11000m/36000ft) without reheat and
for extended periods. Later information appeared to suggest this
figure had increased to M1.3. However even more recently EADS have
stated a maximum upper limit of M1.5 is possible although the
configuration of the aircraft is not stated for this scenario (an
essential factor in determining how useful such a facility is). "

Uh. . . you still missed the source :-). It sounds a lot like the
Airtime Publishing blue book (Airpower somethin-or-other) that had the
Typhoon for the focus aircraft a few years ago though. In it they
mentioned that in turning the Eurofighter could outdo anything except
the F-22 had better sustained turning at both subsonic and supersonic
speed and better instantainious at high speed. The only area the
Eurofighter was better according to the article was instantainious at
subsonic speed.

Yup your right, its at .65 M the Typhoons a tad better at
instantaneous turn rate, not the 1.6 Mach where the F-22 is a tad
better, the reference was on pages 95/96 of the World air power
journal #35.

Seems the F-22's Thrust vectoring really helps in the sustained
rate!!.

FWIW the Tomcat could do 7.5g at Mach 2.2 because of those little flip
out canard-like things in the glove. They didn't even have to move,
all they did was bump the center of pressure forward to offset the
effect of increased stability brought on by the higher speed.
