Saab and Embraer, partnering with Brazilian Air Force, have completed certification tests for in-flight refueling between F-39 Gripen E fighter jets and KC-390 Millennium transport aircraft, marking a significant milestone for both manufacturers.

Operation Samaúma test campaign took place at Embraer's Gavião Peixoto facility, home to Gripen Flight Test Centre. Around 40 engineers and test pilots from Saab, Embraer and Brazilian Air Force participated in trials coordinated by Department of Aerospace Science and Technology.

Teams evaluated various speeds, altitudes and flight configurations. Both aircraft use fly-by-wire controls, which manufacturers say helped maintain stable handling during fuel transfer. KC-390 produced favorable wake conditions whilst Gripen E remained responsive in close formation.

Tests had dual objectives. First was certifying Gripen E as receiver, confirming its stability when taking fuel from KC-390's hose-and-drogue system. Second verified compatibility across KC-390's full refueling envelope, including high-speed transfers during day and night operations.

Walter Pinto Júnior, Embraer Defense & Security COO, said milestone confirms KC-390's tanker capabilities, highlighting its conversion from transport to tanker within few hours. Saab's Head of Flight Testing Mikael Olsson stated trials demonstrate Gripen E has reached "a new level of operational reach".

Swedish Military Aviation Authority will now review refueling data for Gripen E certification. Brazil's Industrial Promotion and Coordination Institute will conduct airworthiness work for Brazilian Air Force.

Capability strengthens Embraer-Saab partnership. Brazil is assembling Gripen E/F locally, whilst Sweden plans acquiring KC-390 for airlift fleet renewal. Certification gives both manufacturers stronger joint export proposition.
