Anti-Air Warfare


Anti-Air Warfare

Threat target detected by AWACS aircraft and Air Defence warship sensors.Surveillance data Communicated to ground-based Head Quarters, Combat Air Patrol (CAP) and Surface units as a ‘Track Report’


Anti-Air Warfare

Head Quarters transmits Command information to the AWACS aircraft.


Anti-Air Warfare

AWACS transmits Control information directing the Combat Air Patrol aircraft to engage the specified target.


Anti-Air Warfare

Combat Air Patrol achieves sensor detection, allocates and launches weapon, reporting engagement status.

Figter-FighterCould use Dedicated or, more usually, Contention Access, which may be less onerous than the Control Backlink since, currently for fighters, there is no R/C requirement. Thus closest terminal capture works in favour of closer unit exchanges of target and engagement information and stack/multi-netting may be avoided if desired.
