Re: 2.5MW
There's a series of aviation primary radars used for en-route tracking (so, long-distance, not just airport approach) that apparently have a rated peak power of > 2.5 MW. Think there's one on Belgium of this type although I can't recall what the power rating was. I do recall it being high, however.
