I'm certain the F22 radar cross section is smaller.
And then there's the.... no, wait, if I told you that I'd have to kill you.
Also, my understanding is that the type 45 destroyers are using only technology licensed from US developers.
The nick name for the USS Ronald Reagan is the "Ronnie ray gun" for a reason, folks. (it's better and faster than Teddy's "big stick.")
The Brits can certainly track and launch against a target the size of a "cricket ball" (roughly the size of a softball), but they'll be launching a conventional weapon, either a missile or something like an (American) Phalanx system. The US developed the tracking and guidance systems with them (and others) that they're touting here. Our purpose is to use them with directed energy systems.
They absolutely contributed heavily to this development (as did the Israelis and several other allies to be named later) but this article implies that it is some sort of British coup (and a march on those nasty Yanks). The real professionals in the British Navy are not into that sort of stuff. Their PR flacks and media drones, however...
Your post reinforces the assurance we should feel if Iran were stupid enough to try and block the Strait of Hormuz. We could station the Navy there which, in conjunction with the Air Force, would defend against sea and land-based threats - silkworm anti-ship missles and other shore hazzards. Even if an Iranian missle were to somehow get within several miles of an American ship, well, I assume you know what a radar-guided Phalanx system can do to an incoming target in a fraction of a second :)
