The original ARI5930/3 Searchwater radar and its display systems of the AEW.2 and
AEW.2A were showing their age and technical deficiencies led to operating compromises. Project Cerberus was launched to address these shortcomings and in Mar 2002, the first Sea King ASaC.7 (originally to be the AEW.7) was issued. It carried an improved Searchwater 2000 radar (trialled by
XZ570) with accompanying mission systems.
The Sea King ASaC.7 is due to be retired from UK service (with
849 NAS) at the end of Sep 2018. This will leave the UK Armed Forces with another capability gap, as the replacement system - the dismountable
Crowsnest to be fitted to
Merlin airframes in their Squadron workshops - is not yet ready for service. The final flight of the ASaC.7 was on 26 Sep 2018 when the last three operational airframes from 849 NAS left RNAS Culdrose via Boscombe Down and Yeovil for VA
Fleetlands and storage awaiting disposal.
