The Senior Hunter / Senior Scout aircraft are designed to support EC-130E Commando Solo operations. Senior Scout is a modular capsulized radio signal monitoring sensor package that attaches antennaes to easily-removed panels such as landing gear doors and aft crew doors. Senior Scout collects SIGINT (signals intelligence), ELINT (Electronic Intelligence) and COMINT (Communications Intelligence) The entire system can be fitted to a standard C-130, but there are four airframes operated by the 193rd Special Operations Wing that serve as the primary aircraft for this system. Each system carries four to twelve operators to monitor the different frequencies.
