What about this Laser CIWS being talked off?
Going back to this comment by Navaleye:
A Falklands scenario becomes very interesting when a T45 is added. Two T45 positioned along the threat axis between Rio Grande, Rio Gallegos and Santa Cruz would make the transit from Argentina impossible without AAR (which is a rare commodity in Argentina today). Another T45 stationed of the northern coast of East Falklands could control all air movements in and out of Stanley and presumably a captured MPA. With ASaC support, you could achieve complete air dominance in an AOA even without fighter defence.
If a T45 is used for APT(S), thati s quite a deterrent. Of course, that also raises the issue of submarines threats, and (decent) sonar, helicopters (why not carry more than one?) and other equipment.
