A while back I saw a short documentary about a joint US German experiment where they basically took an F-18 and slapped a thrust vectoring nozzle on
the back.
While the US also tried the F-18 with thrust vectoring, the US-german joint project was the MBB-Rockwell X-31, a purpose-built testbed aircraft to
maximize possibilities and data output. The engine and TVC equipment were mainly built by german MBB (Messerschmitt-Bölkow-Blohm) and nowadays MTU
Aeuroengines develops the Typhoon TVC technology. Both MBB and MTU were part of DASA (now EADS) until 2000. BTW, if I am not mistaken the X-31 was the
most-flown aircraft by sorties of all the experimental planes built under NASA authority.
And yes, it IS possible to put TVC on the Eurofighter Typhoon (see below).

It's possible, sure, there are plans for it but whether it will actually happen is uncertain.
The technology is just short of being finalised, literally all it needs is a definitive "go" (and the accompanying funds...) of at least a part of
the user nations. Implementation is seen as possible from 2010 onwards (timeframe includes the necessary flight clarifications and tests).
You can't just put it on there though, the engines would have to be redesigned to accommodate TCV.
Well, thats why both the EJ200 turbine and the Eurofighter fuselage are already built so they can accomodate the TVC equipment
. Mind you, the
first 3d TVC flight of a Typhoon took place in 1998. No major work on the aircraft in general is necessary for the system, right now they are working
on making it lighter and ensure durability.
And I don't know how useful 3D TVC would be seeing as how the clearance between the engine exhausts isn't that great.
Still it could benefit at least as much as an one-engined TVC aircraft, no? And TVC is not only useable for extreme maneuvers, they can improve
general flight stability, allow drag reduction and may ease structural stresses during maneuvers. A 2D TVC isnt as helpful for these applications.
Anyway,
here´s a comprehensive article with details to the EJ200 engine and
the TVC technology - quite interesting I´d say because its method of operation seems so simple yet effective. Basically the nozzle forms a three-part
cardan joint that both allow for as little as three or four actuators to be used as well as keeping these actuators away from the intense heat.
