 The upgrade programme resulted in the Sea King AEW fleet being upgraded with a new mission system , Comms , NavAids , JTIDS , Active Noise Reduction and Videographic recording . The Mission System Upgrade ( MSU ) component ( Radar and partial JTIDS integration ) was based around the improved Searchwater 2000AEW radar , with an all @-@ new man Machine Interface . This MSU component was later termed " Project Cerberus " by Thales , after successful integration was conducted by Westland and GEC @-@ Marconi . This variant was initially referred to as the Sea King AEW7 , but renamed ASaC7 just before In Service Date . ( Airborne Surveillance and Control Mk.7 ) . The main role of the Sea King ASaC7 is detection of low @-@ flying attack aircraft ; it also provides interception / attack control and over @-@ the @-@ horizon targeting for surface @-@ launched weapon systems . In comparison to older versions , the new radar enables the ASaC7 to simultaneously track up to 400 targets , instead of an earlier limit of 250 targets . The effectiveness of the AEW7 was greatly increased via the addition of a Link 16 data link , allowing gathered radar information to be analysed and rapidly put to use by multiple allied platforms in range .
