1:250 Embraer KC-390 Millenium (Lupa)
In 2007, the Embraer company of Brazil announced plans for a military cargolifter, originally the "KC-390", later the "C-390", to be derived from the Embraer 190 jetliner. As initially envisioned, the C-390 would use the wings, tail, engines and avionics of the E190 along with a new fuselage, providing a maximum payload of 19 tonnes (21 tons) -- placing the C-390 in the payload range of the C-130 Hercules. The primary target customer was the Brazilian Air Force (FAB).
The design evolved into an effectively all-new aircraft with a maximum payload of 23 tonnes (25.3 tons), comfortably exceeding the 21.8 tonnes (24 tons) of the state-of-the-art C-130J. As introduced, the C-390 had a typical jet cargolifter configuration, with high swept wings, a high-bypass turbofan engine under each wing, a boxy fuselage with landing gear in sponsons, and a high tee tail with a tail loading ramp.
The aircraft is powered by International Aero Engines (IAE) V2500-E5 turbofans, with thrust in the range of 100 kN (10,200 kgp / 22,500 lbf). The V2500 engines also powers the Airbus A320 CEO midsize jetliner family. The V2500-E5 engine was ruggedized, with a modified control system and an improved thrust reverser for short-field landing capability of the C-390.
The cockpit features a Rockwell-Collins Pro Line Fusion system, with five large-screen displays and twin HUDs. The cockpit is compatible with night vision goggles, and the aircraft was fitted with a defensive countermeasures suite. The C-390 incorporates a fly-by-wire flight control system implemented by BAE Systems of the UK.
The C-390's cargo compartment is 17.75 meters (58 feet 2 inches) long, 3.45 meters (11 feet 4 inches) wide, 2.9 meters (9 feet 6 inches) high forward of the wing, and 3.2 meters (10 feet 6 inches) high aft of the wing. Maximum payload of the C-390 is 26 tonnes (28.6 tons). One unusual feature is a movable pressure bulkhead that retracted garage door-style into the roof, and descended to seal the cargo cabin. When lowered, this sloping bulkhead reduced compartment length to 12.78 meters (41 feet 11 inches) at the ceiling. The KC-90 can carry up to 88 equipped troops or 66 paratroopers. Alternatively, it can carry up to seven standard cargo pallets, three tactical vehicles, a single LAV-25 combat vehicle, or a Sikorsky UH-60 Black Hawk helicopter.
Baseline configuration featured an inflight refueling probe above the cockpit -- and for the tanker mission, a hose-drogue refueling pod under each wingtip. The refueling pods were supplied by Cobham Mission Equipment of the UK, being slightly altered from a standard Cobham product.
The first of two C-390 prototypes was rolled out in October 2014, with initial flight on 3 February 2015. The second prototype performed its first flight on 28 April 2016, with the first production machine performing its initial flight on 9 October 2018. The first delivery to the Brazilian Air Force was in 2019, with 30 to be obtained by 2026 -- including the two prototypes, to be brought up to operational specs. In that same year, the designation was changed from KC-390 to C-390, the aircraft being given the name of "Millennium"; users flying it as a tanker will retain the KC-390 designation. Portugal, which is a partner in the C-390 program, committed to buying five in 2017, with an option for one more.
A C-390 of the Brazilian Air Force is on static display at Aero India '23 and is apparently in the running for IAF's requirement of a new medium transport aircraft (along with the Airbus A400, LM C-130J & Kawasaki C-2).
