Since the end of the Cold War, the RAF Tornado F.3, really a specialized Soviet bomber destroyer for UK air defence, have been somewhat lacking a role.
However, some have been fitted with ALARM anti radar missiles, (which are routinely carried by Tornado GR
However, the F3 mod includes equipment to enhance the SEAD role, such as emitter locator equipment, similar to the Lufwaffe Tornado ECRs (which carry HARM missiles), and the USAF
The project was offered to Saudi Arabia for it's F3's, not taken up, restarted for Kosovo in 1999, then ditched again.
Apparently there was a pic posted on PPRune of a RAF F3 carrying ALARMS, it is not there now, though the thread is with a link, in the military section, ('Tornado F3, The Secret Wild Weasel?')
ALARM entered service in 1990, and was very successful in the Gulf and Kosovo, one advantage is that it can be fired upwards, where it slowly floats down on a parachute, this counters a common tactic with SAM crews, who switch off their radars when the enemy appear, to prevent the HARM's from homing on them, with ALARM, the aircraft go away, the radar is back on, and the missile floating downs picks it up, ditches the chute, fires it's rocket, and hits the target, this was found to work in the Gulf and Kosovo.
So the F3s will be a much more useful asset this time, which would explain their deployment when there are plenty of better air superiority fighters out there, and Iraq's air force is very denuded.
