Food for thought, given that the UK has effectively no anti-ballistic missile defence, bar any T45s that may be available.
Three things to think about there.
1. A missile that range is outside the current engagement envelope of the T45 Aster 1 missile envelope, the planned upgrade to enable it won’t be done till the mid-2030s*.
2. With Dragon in the Med the only available T45 is Duncan, but th question is does she have missiles on board or would she have to go to Gibraltar to replenish.
3. Does the UK a suitably robust ABM C3 net to link Fylingdales BMEWS, T45 and No 10 to enable target detection, identification, decision making and interception with the missile time of flight.
