Electronic Warfare Officer

In the U.S. Air Force, an electronic warfare officer (EWO) is a trained aerial navigator who has received training in enemy threat systems, electronic warfare principles and overcoming enemy air defense systems . These officers are specialists in finding, identifying and countering air defense systems and also radar-, infrared- and optically guided surface-to-air missiles, anti-aircraft artillery as well as enemy fighter planes. In aircraft that could penetrate enemy airspace EWOs protect their aircraft using radar jamming, chaff and flares to deceive potential threats. In other aircraft EWOs work to gather intelligence information on potential enemy air defense systems and communication systems.

For decades the U.S. Air Force used fully trained navigator officers as EWO trainees, or EWOT. Their primary training was carried out by the 453d Flying Training Squadron at the former Mather AFB, California near Sacramento. Their follow-on training as EWOs, called "Combat Crew Training School" (CCTS), was usually carried out at the units to which they had been assigned. The B-52 Stratofortress CCTS was conducted at Castle AFB, California in B-52G models. B-52H model differential training was conducted at the gaining Unit location. EWOs could also be assigned to F-105G Thunderchief Wild Weasels, F-4 Phantom II, F-111 Aardvark, C-130 Hercules versions (MC-130, EC-130, etc.), B-1 Lancer or a number of versions of the RC-135.
