Ultra’s Multi-Static Active System (MSA) sonobuoys detect and track submerged targets and comprise several versions. The RN’s ‘grey’ Merlin Mk2 helicopters are upgraded versions of the original AW101 Merlin Mk1 which entered service . The Merlin Mk2s entered service last year and are ship-based providing airborne anti-submarine warfare capability. They will also feature the new Crowsnest Airborne Surveillance and Control (ASaC) system.
