The EC-130J Commando Solo is a modified C-130J Hercules used to conduct psychological operations (PSYOP) and civil affairs broadcast missions in the standard AM, FM, HF, TV and military communications bands. Missions are flown at the maximum altitudes possible to ensure optimum propagation patterns. The EC-130J flies during either day or night scenarios with equal success, and is air-refuelable. A typical mission consists of a single-ship orbit which is offset from the desired target audience. The targets may be either military or civilian personnel. The Commando Solo is operated exclusively by the Air National Guard, specifically the 193d Special Operations Wing (193 SOW), a unit of the Pennsylvania Air National Guard operationally gained by the Air Force Special Operations Command (AFSOC). The 193 SOW is based at the Harrisburg Air National Guard Base (former Olmstead AFB) at Harrisburg International Airport in Middletown, Pennsylvania.
