Embraer C-390 is a medium-sized twin-engined jet-powered military transport aircraft proposed by the Brazilian aircraft manufacturer Embraer. It will be the heaviest aircraft that the company has made so far, and will be able to transport up to 19 tons of cargo, including wheeled armored vehicles. Size-wise it is an aircraft between the twin-turboprop C-27J Spartan, with an 11.5 ton payload and the C-130J Hercules with a 21.7 ton payload. The aircraft will incorporate many of the technological solutions from the Embraer E-Jets series.
The aircraft will have a rear ramp for loading and unloading a wide range of cargo.
The unit price is estimated to be around $50 million US, while the competition sells similar models for up to $120 million. The vice president of Embraer, Luís Carlos Aguilar, said that according to their estimates, some 695 military transport aircraft in the world will need to be replaced during the next decade, and that there is potential market for this kind of plane.
The Brazilian postal service, the Correios, has demonstrated interest in buying at least 5 and eventually 20 to 25 of the aircraft, in lieu of using commercial freight service for mail transport.
In May, 2008, the Brazilian Congress released 800 million Reais(US$ 470 million) to be invested in the project and development of the aircraft. The media also claimed that this aircraft is not only going to be used by the Brazilian Air Force, but also for Brazilian Army and Brazilian Navy, but still not confirmed for government agencies.
