The contracts to AEL, worth a combined $25 million, are for self-protection suite, directional infrared countermeasures and pilot orientation heads-up display.
This selection is in addition to the earlier selection of AEL as the provider of the mission computer for the new jet.
"We are very proud to have been selected to provide Embraer's KC-390 with our cutting-edge technological systems -- the SPS, DIRCM and HUD -- in addition to the mission computer that has already been selected," said AEL President Shlomo Erez.
"This selection attests to AEL's relevance to the most advanced aircraft industries and we are pleased to have this opportunity to share our know-how and proven experience with our partner."
Embraer is developing the KC-390 under contract with the Brazilian air force. Initial test flights of the transport and refueling aircraft are planned for 2014 and the first delivery of KC-390 for 2016.
