The current-generation Hercules, and usually the most numerous military type in the air worldwide. Live positions for every C-130J transmitting now.
If one type dominates the live count on any given day, it is normally this one. Twenty-odd air forces fly the C-130J, it is used for everything from parachute training to hurricane reconnaissance, and a great deal of that flying happens in airspace with dense ADS-B coverage.
The J is a deeper change from the earlier Hercules than the name suggests: new engines, six-bladed composite propellers, a two-pilot glass cockpit and no flight engineer. The airframe outline is familiar, the systems behind it are not.
The designator C30J covers the stretched C-130J-30 as well as the special mission variants — HC-130J rescue tankers, KC-130J refuellers, EC-130J broadcast aircraft — so the aircraft on this page are doing quite different jobs from each other.
The J has Rolls-Royce AE 2100 engines with six-bladed propellers, a digital cockpit, and a crew of three instead of five. Externally the propellers are the giveaway. On this site the older marks appear under the separate C130 designator.
It is widely operated, it flies short sorties so several rotations happen per day, and much of that flying is over Europe and the continental United States where ADS-B receiver coverage is dense.
KING is used by US Air Force combat search and rescue units, most often on the HC-130J, which refuels rescue helicopters in flight and can drop pararescue teams.
