The KC-390 collaboration is part of an agreement that Boeing and Embraer signed in April. The companies previously announced that they are exploring ways to cooperate in commercial airplane efficiency and safety, research and technology, and aviation biofuels. Boeing and Embraer will conduct a joint market assessment for the medium-lift military transport market and analyze business collaboration models. The market assessment includes potential customers that had not been considered in the initial market prospects for the KC-390.
The KC-390 is a Brazilian Air Force project which Embraer signed the development contract for in April 2009.
Boeing's relationship with Brazil dates back to 1932, when Boeing delivered the first F4B-4 fighters to the Brazilian government. Boeing opened its office in São Paulo in October.
