Navaleye,
It wouldn't need to cope, because
1) There's now a proper airfield on the Falklands, with based F.Mk 3s, and able to accept reinforcements.
2) Our Lords and masters work on the assumption that we will do coalition ops, so if we need fleet AD, the Yanks can provide it.
And more to the point of your question, to maximise the potential of ASRAAM you need the HMSS and a full digital integration. They can always go and look at Nightcat.....
