Boeing Unveils Land-Based MQ-25 Autonomous Tanker
Design

Boeing is designing a larger, land-based version of its uncrewed MQ-25 tanker, targeting U.S. Air Force (USAF) future refueling plans including topping up Collaborative Combat Aircraft (CCA) in contested airspace.
Company officials say they have been working
with the Air Force on the design, which expands the 75-ft. wingspan of the
Navy’s Stingray design to 92 ft. The land-based variant would also no longer
require the wings to be folded like the carrier-based version, a change that
combined with the increased span would provide 40% more space for fuel in the
wings.
Boeing officials
say the design is worked internally and not directly linked to work the Air
Force is undertaking with its Next-Generation Aerial Refueling System (NGAS)
analysis of alternatives that is set to wrap this fall. That analysis is
expected to include a family-of-systems approach, including a smaller,
autonomous tanker for operating in contested environments.
John Scudi, Boeing’s acting MQ-25 advanced
capabilities program manager and senior manager of business development, tells
Aviation Week the design would also target roles beyond refueling, including
intelligence, surveillance and reconnaissance, airborne early warning and
electronic warfare.
Boeing is
unveiling the design Sept. 16 at the Air & Space Forces Association’s Air
Space & Cyber Conference. The OEM shared a rendering of the design with
Aviation Week ahead of the show. It shows the MQ-25 Land Based Variant (LBV)
bringing on fuel from a KC-46’s wing refueling pods. The LBV is not designed
with its own refueling boom, which would preclude it from topping up USAF combat
aircraft, and instead is initially focusing on a hose-and-drogue system.
Instead, Scudi says the LBV’s use could
be targeted toward CCAs if the designs can include a receiver probe. This could
be potentially adapted for future CCA increments, which are expected to have
more exquisite requirements than the first increment. Additionally, the LBV
could be used to refuel U.S. Navy fighters already outfitted with receiving
receptacles.
Scudi says the LBV’s use is targeted at
higher-threat areas where existing tankers, such as the company’s KC-46, would
not operate. The MQ-25 could top up from a KC-46 and then move forward into a
higher-threat area to refuel combat aircraft.
“How do you operate in a contested
environment? Would you do a different idea in terms of providing fuel to the
warfighters, especially in an [area of responsibility] that’s as expansive as
the Pacific?” Scudi asks.
Boeing’s goal
with the LBV is to take advantage of all of the investment from the U.S. Navy
in its MQ-25 program of record, with the only change to the aircraft being the
expanded wings. Boeing looked
at six potential redesigns of the wing to increase the aircraft’s capability,
settling on the 92-ft. wingspan after thousands of hours of modeling and
simulation for both refueling and other mission sets. The LBV would keep the
same fuselage, mission systems and engine—the Rolls Royce AE 3007N.
The expanded wings not only allow the
aircraft to carry fuel for its entire wingspan, but also add two additional
3,000-lb. pylon stores that could carry refueling equipment or other systems,
including weapons, Scudi says.
