Embraer has teamed up with Northrop Grumman to advance the KC-390 Millennium’s aerial refueling capabilities, with the goal of expanding its appeal to the US military and allied operators.
At present, the KC-390 uses a probe-and-drogue refueling system, which prevents it from servicing many US Air Force fighters — such as the F-35A, F-15, and F-16 — that require boom refueling. To overcome this limitation, the companies signed a memorandum of understanding to explore integrating an autonomous refueling boom that could be installed as an optional upgrade and retrofitted to aircraft already in service.
The partnership will also focus on incorporating flexible mission systems and enhancements to communications, situational awareness, and aircraft survivability.
By collaborating with a major US defense contractor, Embraer strengthens its position in the American defense market and improves compliance with NATO standards. In addition to the proposed boom capability, the aircraft received a refreshed exterior livery last year.
Aircraft Capabilities
Based on the C-390 airlifter platform, the KC-390 is a versatile tanker-transport aircraft designed for aerial refueling, cargo transport, and rapid deployment missions. It aligns with the US Air Force’s Agile Combat Employment concept, which emphasizes dispersed basing and operations from austere locations.
The aircraft is 35 meters long, carries a maximum fuel load of 23,000 kilograms, and can exceed speeds of 900 kilometers per hour. It operates at altitudes up to 11,000 meters and has a maximum range of 6,000 kilometers.
