 The upgrade programme resulted in the Sea King AEW fleet being upgraded with a new mission system , <unk> , <unk> , JTIDS , Active Noise Reduction and <unk> recording . The Mission System Upgrade ( MSU ) component ( Radar and partial JTIDS integration ) was based around the improved Searchwater <unk> 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 <unk> , but renamed ASaC7 just before In Service Date . ( Airborne Surveillance and Control <unk> ) . 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 <unk> 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 .
