U.S. Navy Tests High-Altitude Maritime Surveillance Drone MQ-9B SeaGuardian

The U.S. Navy recently tested the MQ-9B SeaGuardian, a high-altitude maritime surveillance drone developed by General Atomics Aeronautical Systems. The aircraft, capable of operating at altitudes of 12,000 meters for up to 30 hours, was evaluated by the Maritime Patrol and Reconnaissance Force (MPRF) Commander’s Operational Group. The MQ-9B SeaGuardian is a maritime variant of the MQ-9B unmanned aircraft system, currently operated under a contract with GA-ASI in support of the 7th Fleet’s ongoing capability assessment.

Patrick Shortsleeve, GA-ASI vice president of strategic development for the Defense Department, expressed satisfaction with the drone’s demonstration at the Navy tactical symposium. The MQ-9B SeaGuardian is being evaluated as a potential force multiplier for missions such as maritime domain awareness, surveillance, anti-surface warfare, and anti-submarine warfare. It also supports search-and-rescue, disaster response, and maritime law enforcement operations.

The drone features a wingspan of about 24 meters, a length of 11.7 meters, and a maximum takeoff weight of approximately 5,670 kilograms. Powered by a Honeywell TPE331-10 turboprop engine, it can reach a maximum speed of about 210 knots. Its long endurance and satellite communications enable extended monitoring of maritime areas, providing real-time situational awareness in all weather conditions.

The MQ-9B SeaGuardian integrates advanced maritime intelligence, surveillance, and reconnaissance capabilities, including a long-range maritime radar, Automatic Identification System, electronic support measures, and an autonomous anti-submarine warfare package. It is the first remotely piloted aircraft system in its class equipped with a Detect and Avoid System, allowing for real-time search and patrol missions over the ocean.
