Development and Design

Origins and Development
The KC-390 program was initiated by Embraer in the mid-2000s to address the growing demand for a modern, versatile military transport aircraft capable of replacing aging fleets like the Lockheed C-130 Hercules. The Brazilian government supported the project with significant investments, including R$800 million (approximately US$440 million) in 2008, underscoring the program’s strategic importance . The aircraft was initially designated as the C-390 before being renamed KC-390 in 2011, reflecting its dual role as a transport and tanker aircraft .
Embraer leveraged its extensive experience in aerospace manufacturing to create an aircraft that combines the robustness required for military operations with the efficiency of modern jet technology. The KC-390 made its maiden flight on February 3, 2015, and received type certification from the Brazilian aviation authority in October 2018 . By November 2019, Embraer rebranded the aircraft as the C-390 Millennium for the global market, while the aerial refueling variant retained the KC-390 designation .
Key Design Features
The KC-390 Millennium features a high-wing configuration with swept-back wings and a T-tail, optimizing its aerodynamic efficiency and stability. Its rugged design allows operations from semi-prepared and damaged runways, making it suitable for austere environments ranging from the Amazon rainforest to the Antarctic continent . The aircraft is powered by two International Aero Engines V2500-E5 turbofan engines, each providing 31,330 pounds of thrust, enabling a maximum speed of 470 knots (870 km/h) and a service ceiling of 36,000 feet .
- Dimensions and Capacity: The KC-390 has an exterior length of 33.5 meters, a height of 11.84 meters, and a wingspan of 33.9 meters. Its cargo bay is equipped with an aft ramp, similar to the C-130 Hercules, and can accommodate up to 26 tons of payload. This includes armored vehicles, helicopters, palletized cargo, or 80 troops .
- Avionics and Systems: The aircraft is outfitted with state-of-the-art avionics, including the Rockwell Collins Pro Line Fusion suite, which features five 15-inch high-resolution displays, synthetic vision capabilities, and advanced flight planning tools. The cockpit is also equipped with dual head-up displays (HUDs) and an enhanced vision system (EVS), significantly improving situational awareness in low-visibility conditions .
- Survivability Features: The KC-390 includes a comprehensive self-protection suite (SPS) comprising a radar warning receiver (RWR), missile approach warning system (MAWS), laser warning system (LWS), and directional infrared countermeasures (DIRCM). Additionally, it features ballistic armor protection against 7.62mm bullets and chaff/flare systems to counter missile threats .
Operational Capabilities

Multi-Mission Versatility
The KC-390 Millennium is designed as a truly multi-mission aircraft, capable of performing a wide range of operations with minimal reconfiguration time (less than three hours) . Its primary roles include:
