The EC-130E Commando Solo entered service in 1978 as the EC-130E Coronet Solo with the Tactical Air Command (TAC). In 1983 the Coronet Solo's mission was transferred to the Military Airlift Command (MAC) and redesignated the EC-130E Volant Solo. With the formation of Air Force Special Operations Command, the mission was transferred to AFSOC and redesignated Commando Solo. Operations were consolidated under a single-AFSOC gained unit, the 193d Special Operations Wing (193 SOW) of the Pennsylvania Air National Guard. In the early 1990s the aircraft were upgraded and designated Commando Solo II. The EC-130E variants were replaced with new EC-130J Commando Solo III aircraft built by Lockheed Martin beginning in 2003.
