The AgustaWestland Apache is a license built version of the Longbow I believe. We've got eight US built Apaches and the rest are built in the UK under license. We put a Rolls Royce engine in her which increased her output a bit, and I believe she can also fire the CRV7 rocket which gives her some punch. We've got Hellfires as well, although it took a while to get the Hellfire to talk to the Helo.
I live about...thirty miles from Wattisham and they bring the WAH-64 over fairly often, it's a beautiful sight. Particularly on a low pass, two of them put on a show the other week...low enough to see the gun moving around.
Oh, and a bit of Apache image spam from me too, because it is a brilliant helo.
