THE DEVELOPMENT OF WEAPONS SYSTEM REQUIREMENTS 



guards against sneak attacks from the rear as well as turn-around and 

 reattack tactics. 



Early warning detection and interceptor vectoring information is pro- 

 vided by airborne early warning aircraft (AEW). The task force is assumed 

 to have a capability for maintaining three AEW aircraft aloft on a 24-hour 

 basis. The primary functions of the AEW system are: 



(1) To provide detection of enemy aircraft at sufficient range forward of 

 fleet center to permit interception by piloted aircraft.
