Boeing will build the U.S. Navy’s first operational carrier-based unmanned aircraft, the MQ-25 aerial refueler, through an $805 million contract awarded on August 30, 2018.

Boeing was awarded the engineering and manufacturing development contract to provide four aircraft. Boeing plans to perform the MQ-25 work in St. Louis.

MQ-25 is designed to provide the U.S. Navy with a refueling capability. According to the U.S. Navy, the MQ-25 Stingray will allow for better use of combat strike fighters by extending the range of deployed Boeing F/A-18 Super Hornet, Boeing EA-18G Growler, and Lockheed Martin F-35C aircraft. MQ-25 will also integrate with a carrier’s catapult and launch and recovery systems.
