Embraer Teams With Northrop to Pitch KC-390 to Pentagon
Brazil’s Embraer has landed the heavyweight American defense partner it has long sought. Northrop Grumman announced Thursday from its Melbourne, Florida facility that the two companies signed a memorandum of understanding to jointly develop an upgraded KC-390 Millennium equipped with an autonomous aerial refueling boom, enhanced communications, situational awareness, and survivability systems.
The target market is clear: the U.S. Air Force and allied nations operating boom-dependent aircraft like the F-35. The KC-390 currently refuels planes using the probe-and-drogue method favored by the U.S. Navy and Marines, but the Air Force exclusively uses boom-and-receptacle across its fleet of over 530 tankers.
Northrop’s three-tier tanker play
The partnership fits into a broader Northrop strategy. According to Aviation Week, the company plans to offer the Pentagon a three-pronged package under its Next-Generation Air Refueling System program: a large blended-wing-body tanker being developed with JetZero, the KC-390 as a midsize tactical refueler, and a small uncrewed tanker.
The KC-390’s appeal for the tactical role rests on its ability to operate from austere airfields with soft-soil runways — a key requirement under the Air Force’s Agile Combat Employment doctrine, which envisions dispersed operations from remote locations across the Indo-Pacific.

Second attempt at the U.S. market
Embraer previously teamed with L3Harris to promote the KC-390 in the United States, but that partnership dissolved in 2024 after two years of work without a sale. Northrop brings substantially more weight: the company leads the B-21 Raider stealth bomber program and has deep relationships across the Department of Defense. Embraer has signaled readiness to open a dedicated KC-390 manufacturing facility in the U.S. if orders materialize.
The KC-390 is already in service with Brazil and has been selected by Portugal, Hungary, South Korea, the Netherlands, Austria, the Czech Republic, Sweden, Slovakia, Lithuania, and most recently Uzbekistan — the first Central Asian operator. Eleven countries now fly or have ordered the aircraft.
Whether the U.S. Air Force ultimately buys the KC-390 remains uncertain. Senior leaders have shown more interest in a stealthy next-generation platform than a midsize tactical tanker. But with roughly 375 KC-135 Stratotankers averaging over 63 years of age and the KC-46 program plagued by engineering shortfalls, the case for a complementary tactical refueler is getting harder to dismiss.
