Embraer is renewing its push for a United States Air Force order of the KC-390 Millennium, framing the Brazilian tanker-transport as a multi-mission airlift and tanker aircraft that would supplement, not replace, the Boeing KC-46 Pegasus fleet. FlightGlobal reported the renewed pitch on September 25, 2026, noting that the KC-390 sits closer in size to the Lockheed Martin C-130J than to large commercial-derivative tankers such as the KC-46 or the Airbus A330 Multi-Role Tanker Transport.
The airframer's message to USAF planners is that medium airlift and tactical tanker capacity remain scarce even as the service fields more KC-46s for strategic boom refueling. Embraer positions the KC-390's jet performance, rear ramp and hose-and-drogue tanker kit as a way to support fighters and special-operations aircraft from shorter runways while moving outsized cargo that would otherwise compete for scarce C-130 or C-17 hours.
Embraer has already delivered KC-390 and C-390 variants to operators including the Brazilian Air Force, Portugal, Hungary, the Netherlands and the Czech Republic, and Colombia ordered two aircraft in 2026. Those export wins give the company a growing in-service base to cite when it argues that the type is mature enough for a U.S. competition. The Multi-Mission Airlift and Tanker branding underscores that Embraer wants evaluators to judge the jet on combined tanker and airlift utility rather than against a pure boom tanker alone.
Any USAF path would still face budget, industrial-base and interoperability tests. Boeing's KC-46 remains the core boom tanker for American heavy aircraft, and Lockheed Martin's C-130J remains the incumbent tactical airlifter. Embraer's pitch therefore stresses complementarity: a jet tanker-transport that can operate where larger commercial-derivative tankers are less efficient, while freeing KC-46 and C-17 fleets for longer-range tasks.
Combat-radius tanker support and austere-field airlift are the mission threads Embraer keeps repeating. The company argues that a jet with a rear ramp can move vehicles and palletized loads that turboprop airlifters struggle to schedule, while still offering hose-and-drogue refueling for receiver aircraft that do not need the KC-46 boom. That combination is what the Multi-Mission Airlift and Tanker label is meant to sell inside U.S. requirement shops.
Industrial politics will matter as much as performance slides. A U.S. buy would raise questions about final assembly, sustainment and how Brazilian-built jets fit beside American-made KC-46 and C-130 fleets. Embraer's export customers already provide a reference for mission kits and training pipelines that a USAF evaluation could inspect, but Washington has historically preferred domestic production for core tanker fleets.
Allies already flying the type give Embraer a logistics story it lacked a decade ago. Shared spare pools, training syllabi and mission-planning tools from European and Latin American customers can be shown to USAF visitors as evidence that the jet is past the prototype stage. Still, none of that substitutes for an American production or sustainment plan if Washington ever opens a formal contest.
No U.S. order has been announced. Until a formal request for information or solicitation appears, the KC-390's American story remains a campaign rather than a contract. The aircraft's export momentum and the clarity of Embraer's supplement-don't-replace line are the concrete developments from this latest round of advocacy.
