The MQ-9B SeaGuardian is a maritime version of the MQ-9 Reaper unmanned aerial vehicle (UAV) developed by General Atomics Aeronautical Systems, Inc.

The primary role of the MQ-9B SeaGuardian is maritime surveillance and reconnaissance, making it well-suited for missions such as anti-submarine warfare

It has an increased payload capacity compared to the standard MQ-9 Reaper, allowing for the integration of additional sensors, mission equipment, and weapons systems

It is equipped with a maritime surveillance radar, an automatic identification system (AIS) receiver, a maritime automatic identification system (M-AIS), an electro-optical/infrared (EO/IR) sensor, and electronic support measures (ESM) for detecting and tracking surface and subsurface targets

The SeaGuardian has an extended endurance of over 40 hours, enabling it to conduct long-duration maritime surveillance missions and provide persistent coverage over large areas

The SeaGuardian can carry and deploy sonobuoys for underwater acoustic sensing, making it capable of conducting anti-submarine warfare operations

It has a maximum payload capacity of 1,746 kilograms (3,850 pounds), allowing for a wide range of mission-specific sensors, equipment, and munitions

Its sensor suite enables it to detect and track surface vessels, including small boats, larger ships, and potentially even submarines

The MQ-9B SeaGuardian can share real-time sensor data and video feeds with other airborne platforms, ships, and ground-based command and control centers, enhancing situational awareness and facilitating coordinated operations

The MQ-9B SeaGuardian has garnered international interest and is being considered by various countries for their maritime surveillance and patrol requirements
