Embraer and Northrop Grumman have partnered to enhance the aerial refueling capabilities of the KC-390 Millennium, positioning the aircraft for potential adoption by the United States and allied air forces.
In its current configuration, the KC-390 supports probe-and-drogue refueling, which limits its ability to refuel most US Air Force fighter jets — including the F-35A, F-15, and F-16 — that depend on boom refueling systems. To bridge this capability gap, the two companies signed a memorandum of understanding to study the integration of an autonomous aerial refueling boom. The boom would be offered as an optional feature and designed for retrofit on existing aircraft.
The collaboration also covers the integration of adaptable mission systems, along with upgraded communications, enhanced situational awareness, and improved survivability features.
Embraer has been actively marketing the tanker-transport platform internationally, and teaming with a leading US defense contractor strengthens its access to the American defense market and alignment with NATO interoperability standards. Alongside the potential boom addition, Embraer introduced an updated paint scheme for the aircraft last year.
KC-390 Millennium Overview
Derived from Embraer’s C-390 tactical airlifter, the KC-390 is a multi-role platform capable of aerial refueling, cargo transport, and rapid response missions. It is also being positioned as suitable for Agile Combat Employment, a US Air Force doctrine focused on distributed operations, rapid redeployment, and functioning from austere airfields.
The aircraft measures 35 meters (115 feet) in length and can carry up to 23,000 kilograms (50,706 pounds) of fuel. It has a top speed exceeding 900 kilometers (559 miles) per hour, an operational ceiling of 11,000 meters (36,089 feet), and a range of approximately 6,000 kilometers (3,728 miles).
