Does the Royal Navy have airborne early warning capability?
Short answerYes. The role is transitioning to Crowsnest-equipped Merlin helicopters rather than a fixed-wing AEW platform.
NotesThe Royal Navy provides airborne early warning through helicopters. Crowsnest equipment fitted to Merlin airframes carries that role forward. Japan and Italy could potentially adapt the same approach because they operate related EH101-family helicopters, although British fleet demand already competes for a limited number of Merlin airframes. A fleet can therefore field the mission even when it uses a different platform type from fixed-wing AEW aircraft.
