"Don't forget F3 already has lots of capability that SHar doesn't. (ASRAAM, JTIDS, multi-crew, speed, turn performance(!), EPM (or is it ECM).........," and range, combat persistence, etc.
What a pity you can't also say a decent ELS, EO GP(1) recce, TIALD, HMSS and all the other stuff that was so nearly incorporated....
