Boeing's KC-46A Pegasus: US Air Force advances amid challenges

Boeing continues to modernize this platform through ongoing upgrades despite reported delays from the Government Accountability Office related to refueling components. "The KC-46A will be equipped with a modernized KC-10 refueling boom integrated with a fly-by-wire control system," according to an Air Force statement.

With orders for additional units underway—15 more planned by summer 2028—the program underscores the strategic importance of aerial refueling for military operations far beyond national borders. As outlined by current procurement plans, it remains uncertain if future requirements will demand greater quantities of these or newer stealth models currently under exploration by Lockheed Martin's Skunk Works division.

Looking ahead, new developments like JetZero’s blended-wing design could represent significant shifts away from traditional tanker models such as those built from commercial airliner frames like Pegasus. However, until then—and without significant increases in production—the venerable KC-135 will likely continue supporting global operations well into coming decades.
