International Aero Engines has shipped to Embraer the first six V2500-E5 engines, which will power Embraer's KC-390 multi-role tanker and transport.
IAE, which is majority owned by Pratt & Whitney, says the engines will be used for flight tests that will start in 2014. Embraer is scheduled to deliver the first certificated KC-390 to the Brazilian air force in 2016.
P&W expects civilian certification of the engine will be achieved in the third quarter of this year.
The engines were assembled at P&W's facility in Middletown, Connecticut, then shipped to parent company UTC's aerostructures plant in Foley, Alabama, for installation of nacelles, thrust reverses and other equipment, says Pratt.
Rated at 31,300lb-thrust, Embraer and the Brazilian Air Force chose the V2500-E5 in July 2011.
The selection by Embraer of the V2500-E5 comes as P&W expects to wind down production of the type in the next five years.
The company tells reporters on 20 May that V2500 deliveries will fall as deliveries of its newest engine, the PurePower geared-turbofan, ramps up.
The geared turbofan will power Airbus A320neos, Bombardier CSeries, Embraers family of second-generation E-Jets and Mitsubishis regional jet.
