INSIGHT

Britain Lacks A National Ballistic Missile Shield

  • The UK has almost no national ballistic missile defense capability.
  • Clarke argues incoming missiles would likely pass over allied airspace where other countries might intercept them, leaving the UK itself poorly defended.
ADVICE

Deploy More Sea Based Air Defence Quickly

  • Increase deployable sea-based air defence and platform numbers to protect the homeland.
  • Clarke suggests dozens of Type 45 destroyers would be needed around UK coasts and more Typhoons with Meteor missiles to have a chance.
INSIGHT

No National Air Defence Since 1991

  • The UK hasn't fielded a dedicated national air-defence system since the Bloodhound retired in 1991.
  • Clarke highlights that current defenses are piecemeal (ship-based, tactical Army systems) and not national coverage.
