Actually,_one_generation apart although that generation is about 30 years
long. Typhoon benefits from better propulsion technology, controls
technology and somewhat better structural technology so it would be
strange
if a Typhoon wasn't substantially better than a F-15C. In fact if it turns
out not to be, a passel of British aero- and -propulsion engineers should
be
looking for jobs.

Now the story is they were C models?
