Boeing preps for next test of US Navy’s future aerial tanker drone
By: David B. Larter
WASHINGTON — The U.S. Navy's aircraft carrier-borne tanker drone, the MQ-25 Stingray, is preparing to head into the fall resuming test flights, this time with the crucial fuel store pod attached.
The store pod — the same one integrated into the Navy's stalwart F/A-18 Super Hornet for aerial refueling — was recently integrated into the MQ-25 test article under the wing.
“When we resume flight testing later this year, we'll have the opportunity to gather test points about the aerodynamics of that pod and the software commands that control it — all happening well before we deliver the Navy's first MQ-25 jet with the same pod,” MQ-25 program director Dave Bujold said in a statement from the aircraft's manufacturer, Boeing.
“That early testing and early software development is a big part of supporting the Navy's goal to get MQ-25 to the fleet as quickly as possible,” he added.
The engineers will primarily observe the aerodynamics of the pod mounted on the Stingray test article, then seeing how the hose and drogue behave while being dragged behind the airframe.
Possible delays
In June, Defense News reported that the MQ-25 could face a three-year testing delay if it doesn't get its designated test ships through the required modernizations on time, a possibility the Navy said was remote.
Two carriers — Carl Vinson and George H.W. Bush — have limited windows to complete the installation of unmanned aircraft control stations, and if operational commitments intervene, the program could experience significant problems, according to Navy officials and a government watchdog report.
“Program officials stated that, among other things, the Navy's potential inability to maintain its schedule commitments could require modifications to the contract that would impact the fixed-price terms,” the Government Accountability Office reported. “Specifically, the Navy faces limited flexibility to install MQ-25 control centers on aircraft carriers.
“If the Navy misses any of its planned installation windows, the program would have to extend MQ-25 development testing by up to 3 years. According to officials, such a delay could necessitate a delay to initial capability and result in a cost increase.”
The Navy's MQ-25 Stingray aerial refueling drone took its first flight Sept. 19, a historic step toward integrating an unmanned aircraft into the service's powerful strike arm.
Navy officials say a three-year delay is “extremely unlikely”; however, the Navy has struggled in recent years to balance its modernization schedules with operational commitments, a problem that its “Optimized Fleet Response Plan” deployment rotation scheme was supposed to address. Ultimately, a delay would further push back the Navy's ability to extend its carrier air wing's range through unmanned tanking, critical to keeping the service's powerful strike arm relevant against long-range guided munitions.

First test flight for Boeing MQ-25
Boeing and the U.S. Navy on September 19 completed the first test flight of the MQ-25 unmanned aerial refueler. Designated as T1, the MQ-25 test asset completed an autonomous two-hour flight under the direction of Boeing test pilots operating from a ground control station at MidAmerica St. Louis Airport in Mascoutah, Ill., where the test program is based. The aircraft completed an autonomous taxi and takeoff and then flew a pre-determined route to validate the aircraft's basic flight functions and operations with the ground control station. “Seeing MQ-25 in the sky is a testament to our Boeing and Navy team working the technology, systems and processes that are helping get MQ-25 to the carrier,” said Boeing MQ-25 program director Dave Bujold. “This aircraft and its flight test program ensures we're delivering the MQ-25 to the carrier fleet with the safety, reliability and capability the U.S. Navy needs to conduct its vital mission.” The Boeing-owned test asset is a predecessor to the engineering development model (EDM) aircraft and is being used for what the company describes as early learning and discovery to meet the goals of the U.S. Navy's accelerated acquisition program. Boeing will produce four EDM MQ-25 air vehicles for the U.S. Navy under an US$805 million ($1.1 billion) contract awarded in August 2018. Boeing receives $805M MQ-25 contract Boeing explains the MQ-25 will provide the Navy with a much-needed carrier-based unmanned aerial refueling capability, which will allow for better use of the combat strike fighters currently performing the tanking role. It will also extend the range of the carrier air wing. “Today's flight is an exciting and significant milestone for our program and the Navy,” said the Navy's Unmanned Carrier Aviation (PMA-268) Program Manager Capt. Chad Reed. “The flight of this test asset two years before our first MQ-25 arrives represents the first big step in a series of early learning opportunities that are helping us progress toward delivery of a game-changing capability for the carrier air wing and strike group commanders.” The Navy expects the first four MQ-25s to reach operational capability on carrier decks in 2024. After this contract is complete, covering the design and production of the four MQ-25 airframes for testing, the Navy plans to buy 72 more vehicles with a total program cost of about US$13 billion ($17 billion). Héroux-Devtek to supply landing gear for Boeing MQ-25 Stingray In April 2019, Héroux-Devtek Inc. of Longueuil, Québec, was awarded a contract by Boeing to supply the complete landing gear system for the MQ-25 unmanned aerial refueling program. T1 received its experimental airworthiness certificate from the FAA in September, verifying that the air vehicle meets the agency's requirements for safe flight. https://www.wingsmagazine.com/first-test-flight-for-boeing-mq-25
