Despite the closure of Olmsted AFB in 1969, the US Air Force continues an Air National Guard presence at Harrisburg in the form of Harrisburg Air National Guard Station and the Pennsylvania Air National Guard's 193rd Special Operations Wing (193 SOW), an Air Force Special Operations Command (AFSOC)-gained unit flying the EC-130 Commando Solo aircraft. The 193 SOW is the sole operator of this critical aircraft asset for the entire US Air Force and in 2001 transitioned from the EC-130E to the new EC-130J variant. The wing has seen extensive federal service in recent years in support of Operations Just Cause, Desert Storm, Enduring Freedom and Iraqi Freedom.
