Boeing to integrate ground-control station for U.S. Navy MQ-25 unmanned carrier airborne refueling aircraft

The MQ-25 is the U.S. Navy's first operational carrier-based unmanned aircraft and is designed to provide a much-needed refueling capability.

PATUXENT RIVER NAS, Md. – U.S. Navy carrier aviation experts are asking the Boeing Co. to build ground control stations for the U.S. Navy MQ-25 unmanned refueling aircraft under terms of a $198 million order announced late last month.

Officials of the Naval Air Systems Command at Patuxent River Naval Air Station, Md., are asking the Boeing Defense, Space & Security segment in St. Louis to integrate a ground-control station that provides command and control capability in support of the MQ-25 carrier airborne refueling unmanned aerial vehicle (UAV).

The MQ-25 is the U.S. Navy's first operational carrier-based unmanned aircraft and is designed to provide a much-needed refueling capability, Boeing officials say. Navy officials expect to declare MQ-25 initial operational capability by 2024. The MQ-25 first flew in 2019.

The MQ-25 will provide carrier-based refueling capability to extend extending the combat range of deployed F/A-18 Super Hornet, EA-18G Growler, and Lockheed Martin F-35C combat aircraft.

Boeing won a $805 million development contract to build four MQ-25 carrier-based unmanned aerial tankers in 2018, prevailing over competing designs built by General Atomics in San Diego and the Northrop Grumman Corp. Aeronautics Systems segment in Palmdale, Calif.

The Boeing MQ-25 aircraft since it first flew has had an advanced, customized remote I/O interface controller based from Aitech Defense Systems Inc. in Chatsworth, Calif. The system is based on the Aitech Ai-RIO avionics remote interface.

The Ai-RIO is expandable with as many as eight units networked together. Added capabilities include I/O, power switching, and mass/SD FLASH memory. The remote I/O subsystem includes a Gigabit Ethernet port with precision time sync IEEE-1588 support, 10 RS-422 ports, eight LVDS or RS-422/485 UARTS, four SpaceWire ports with LVDS I/O, two CANbus ports, and 16 GPIO in two blocks of eight.

The Ai-RIO is an high density, low power rugged subsystem for vehicle platform flight control, attitude and navigation controls, servo-valve and thrust vector control (TVC), robotic motor control, video and image processing and storage, data telemetry, platform stabilization, communications and telematics, high speed data recorders, booster and launch propulsion and thruster control, remote sensor and effector monitoring.

Boeing can use the Ai-RIO as a stand-alone command and data handling platform or networked remote command/response I/O unit. It a radiation-qualified dual-core PowerPC processor with two rad-tolerant FPGAs. All internal electronics are conduction-cooled and mechanically fixed and housed within a sealed, EMI/EMC Faraday cage for maximum thermal transfer.

In addition to Aitech, other subcontractors to Boeing on the MQ-25 project are; BAE Systems; Collins Aerospace; Cox & Co.; Crane Aerospace & Electronics; Cubic; Curtiss-Wright Defense Solutions; General Electric Corp.; L3Harris Technologies; HĂ©roux-Devtek; Honeywell International; Innovative Power Solutions; Moog Aircraft Group; Parker Hannifin; Raytheon; Rolls-Royce; and Triumph Group.

On this order Boeing will do the work in St. Louis and at other U.S. locations, and should be finished in August 2024. For more information contact Boeing Defense, Space & Security online at www.boeing.com, or Naval Air Systems Command at www.navair.navy.mil.
