Raytheon said its integrated electronic warfare suite has been selected by the Royal Moroccan Air Force’s (RMAF) F-16s. The RMAF recently agreed to purchase 24 Block 52 F-16s from Lockheed Martin. Known as "ACES," Raytheon’s countermeasures electronic system consists of a radar warning receiver, digital jammer and chaff-flare dispenser. Raytheon’s contract, received from Lockheed, calls for deliveries to begin in December 2009.
