Sikorsky, a Lockheed Martin subsidiary, and global training and simulation leader CAE are collaborating to supply the CAE Magnetic Anomaly Detection-Extended Role (MAD-XR) system for U.S. Navy and Royal Australian Navy MH-60R SEAHAWK® helicopters. Built by CAE and integrated into the MH-60R’s main mission computer by Sikorsky, this passive digital MAD sensor will enhance the maritime helicopter’s ability to detect and track submarines underwater.

Weighing less than 20 pounds (9 kg) including cabling and mounting, the compact MAD-XR system features highly sensitive magnetometers and a processor/interface unit. It alerts crews audibly when a target is detected and shows contact and range on a display. The system can be installed inside the tail cone without permanent modifications and can be quickly moved between MH-60R aircraft as needed.
Collaboration between Sikorsky, CAE, and the navies involved ensured seamless integration, testing, and optimization of the MAD-XR. In early 2024, the U.S. Navy rolled out software and hardware updates allowing MH-60R helicopters to accommodate the new digital MAD technology.
A $21 million contract awarded to Sikorsky in September 2024—subcontracted to CAE—covers 20 kits for the Royal Australian Navy, six for the U.S. Navy, and two for U.S. Navy Reserve testing, with deliveries ending May 2026. Options exist for more kits in 2025 and 2026.
Cliff Kyle, Sikorsky Australia’s General Manager, welcomed the announcement, praising the Royal Australian Navy as the first MH-60R operator to adopt this advanced digital MAD capability. The CAE MAD-XR outperforms the older AN/ASQ-81 sensor on SH-60B helicopters, which was heavier (90 lbs) and externally mounted, trailing behind the aircraft via a cable and reel system.
