EC-130-J making loops near Atomic City Idaho (Pop. 29). Probably training. Maybe not. Notable that these birds usually fly at night.

Atomic City is located at the edge of the Idaho National Laboratory, an 890-square-mile nuclear complex in the remote desert of southeastern Idaho. Since its establishment in 1949—when it was called the National Reactor Testing Station—the facility has contained more than 50 nuclear reactors, including the now decommissioned Experimental Breeder Reactor-1, which became the world’s first electricity-generating nuclear power plant in 1951.

The EC-130J Commando Solo, a specially-modified four-engine Hercules transport, conducts airborne Information Operations via digital and analog radio and television broadcasts. These missions are often flown at night to reduce probability of detection in politically sensitive or hostile territories.

The EC-130J are flown by the 193rd Special Operations Wing, a Pennsylvania Air National Guard unit, gained by Air Force Special Operations Command.

Many modifications were made to the basic C-130J to create the EC-130, including enhanced navigation systems, self-protection equipment and air refueling. The majority of the engineering investment went into the integration of the special mission equipment capable of up to 14 simultaneous broadcasts with the same or independent messages on each channel. Keeping pace with information-technology systems, message playback is accomplished using media stored digitally, e.g. hard drives, but the aircraft is still capable of accepting legacy media formats (CD/DVD etc.). In addition to pre-recorded messages, the EC-130J has the capability to conduct live broadcasts. In the last two deployments, the live broadcast option has gained considerable popularity. In its current configuration, the EC-130J is capable of a broad-range of tactics including; Information Operations (Influence) and Joint Electromagnetic Spectrum Operations, i.e. electronic attack.
