Developed in the mid-2000s, the KC-390 was conceived as a jet-powered, medium-lift transport designed to rival the Lockheed C-130 Hercules. The program received significant backing from the Brazilian government, which invested R$800 million (US$440 million) in 2008 and awarded a contract for two prototypes in 2009. The aircraft’s maiden flight took place in 2015, and it achieved initial operating capability in 2017, followed by type certification in 2018.

The KC-390 is powered by two IAE V2500-E5 turbofan engines, each producing 139.4 kN (31,330 lbf) of thrust. This configuration allows the aircraft to achieve maximum speeds of 988 km/h and cruise at 870 km/h (Mach 0.8), with a service ceiling of 11,000 meters (36,000 feet). The aircraft measures 35.2 meters in length with a wingspan of 35.05 meters, and it can carry a maximum payload of 26,000 kilograms. Its cargo hold is optimized for flexibility, measuring 18.5 meters long, 3.0 meters high, and 3.4 meters wide, accommodating a range of military vehicles, helicopters, and standard NATO pallets.

Range is a key strength of the KC-390. With a 14,000 kg payload, it can cover 5,020 kilometers, and with a maximum payload, the range is 2,000 kilometers. The ferry range extends up to 8,460 kilometers with auxiliary tanks. The aircraft’s design emphasizes rapid reconfiguration: it can switch between transport, aerial refueling, medevac, and other roles in under three hours. This is enabled by engineering choices such as moving wheel wells outside the cargo bay to maximize internal space.

Advanced avionics are provided by Collins Aerospace’s Pro Line Fusion suite, featuring five 15-inch LCD displays with night vision compatibility. The open architecture supports integration of new systems, while synthetic vision and graphical flight planning enhance situational awareness. The KC-390’s self-protection suite includes radar and missile warning systems, laser warning, directional infrared countermeasures, and ballistic armor for the cockpit and key crew positions. Cargo systems allow for rapid loading and unloading, supporting HIMARS vehicles, Black Hawk helicopters, and a variety of configurations for troops, paratroopers, or medical evacuations.

“The KC-390 was designed for rapid mission reconfiguration, enabling transitions between strategic and tactical roles in less than three hours, a significant advantage over traditional platforms.”

US Market Strategy and Local Production Initiative

Embraer’s approach to the US market is centered on establishing local production to comply with the Buy American Act and to strengthen its competitive position. The company has developed site plans for domestic assembly and is prepared to invest up to $500 million in new US facilities. Embraer’s existing US presence, business jet production in Florida and A-29 Super Tucano assembly in Jacksonville, provides a foundation for expanded operations.

Over 50% of the KC-390’s content is sourced from 59 US companies, including Collins Aerospace, L3Harris, Raytheon, and BAE Systems. This extensive American supply chain integration not only facilitates local assembly but also supports US industrial base priorities. Several US states have shown interest in hosting the new production line, indicating strong domestic support for the initiative.

The timing of Embraer’s push aligns with evolving US Air Force requirements for next-generation aerial refueling capabilities. While the Air Force has opted to purchase additional KC-46 aircraft for now, shifting doctrine toward “survivable air refueling” and agile combat employment opens opportunities for platforms like the KC-390. The aircraft’s ability to operate from short or semi-prepared runways and its rapid reconfiguration are particularly relevant for distributed operations in contested environments.

Embraer’s previous partnership with L3Harris on the “Agile Tanker” concept provided valuable technical groundwork, and there is speculation about future collaborations with other US defense firms. Participation in US exercises, such as Storm Flag, has allowed direct evaluation of the KC-390’s capabilities by American military personnel. The aircraft’s demonstrated capacity to transport and deploy HIMARS missile systems is seen as particularly valuable for Indo-Pacific operations.
