JAPAN. Japan’s Coast Guard completed flight testing of Raytheon Intelligence & Space (RI&S), a Raytheon Technologies business, maritime surveillance technologies onboard a General Atomics Aeronautical Systems, Inc. (GA-ASI) SeaGuardian Remotely Piloted Aircraft (RPA). RI&S provided its SeaVue Expanded Mission Capability (XMC) radar and AN/DAS-4 Multi-spectral Targeting System for the tests.

According to the companies, the tests validated the wide-area maritime surveillance systems support for the Japan Coast Guard to carry out missions for search and rescue, disaster response, and maritime law enforcement.

The SeaVue XMC radar is designed to provide enhanced, wide-area surveillance by identifying targets of interest, such as small maritime vessels. SeaVue MR is engineered to deliver expanded capabilities including small-target detection at longer ranges and higher altitudes, and a software-defined digital architecture to add new functionality without changing hardware.

The DAS-4 sensor suite is intended to offer operators next-generation electro-optical surveillance in high-definition and full-motion video to identify and engage targets. Officials claim that the flight tests support the Japan Coast Guard’s policy on Strengthening Maritime Security System. The policy calls for modernized maritime technologies to protect Japan’s sovereignty.
