Embraer and Saab, in cooperation with the Brazilian Air Force (FAB), have successfully completed the certification flight test campaign for in-flight refuelling of the Gripen E fighter by the KC-390 Millennium multi-mission aircraft.

Conducted at Embraer’s facilities in Gavião Peixoto, São Paulo, where the Gripen Flight Test Centre is located, the campaign was coordinated by the Department of Aerospace Science and Technology (DCTA) from the FAB, and brought together engineers and test pilots from Saab, Embraer and the FAB. During the tests, a range of flight configurations, speeds and altitudes were evaluated and confirmed precision during in-flight refuelling. Both aircraft’s latest-generation fly-by-wire systems contributed to the successful operation, with the KC-390 providing a favourable wake and the Gripen demonstrating responsiveness in flight.
The flight test campaign consisted of two objectives. The first involved qualifying the Gripen E as a receiver for in-flight refuelling — a key step in validating the fighter’s performance, stability, and structural integrity throughout the operation. The second focused on verifying the compatibility of both aircraft across the KC-390’s entire flight envelope, for high-speed refuelling under both day and night conditions. The in-flight refuelling of Gripen E by the KC-390 further enhances interoperability between these two highly advanced, latest-generation aircraft.
The Swedish Military Aviation Authority (SE-MAA) will now be able to review the verification evidence for the air-to-air refueling capability of Gripen E as part of its certification process. This will be followed by the certification process conducted by the Industrial Promotion and Coordination Institute (IFI) of the FAB. These institutions are responsible for the technical analysis and validation of results, ensuring that both aircraft comply with the most demanding international standards.
