Where do I start?
When the Tornado was first ordered it was going to be the only plane in the world with first pass first strike capablility, even the Americans were interested. For a while it was, until the F-15 and other American planes came into service.
When the Tornado was getting tested by the RAF they realised many problems, one was the RADAR alt deflected off the under carriage giving the reading of 7ft when you were 200ft. Some of the systems on the Tornado can be affected by certain frequencies of radio.
The Tornado has to put afterburners on to TAKE OFF! It is slow, sluggish and poorly armed. The EE Lightning beat it on everything except armament, and range. In the first Gulf War, old RAF Bucaneers (Very good, but very old aircraft) had to laser pin point the targets for the Tornados because they couldn't do it, so much for first pass first strike.
For the price of a Tornado you can buy three fully armed, and fully fueled F-15s, when the Tornado would not be armed or fueled. The many mistakes in manufacture meant that it would be mothballed as soon as it was delivered because it basically could not fly safely.
The plane is crap.
