The HC-130J replaces HC-130P/Ns as the only dedicated fixed-wing Personnel Recovery platform in the Air Force inventory. It is an extended-range version of the C-130J Hercules transport. Designed to conduct personnel recovery missions, provide a command and control platform, in-flight-refuel helicopters and carry supplemental fuel for extending range or air refueling. Built by Lockheed, this four-engine turboprop aircraft is quite possibly the most versatile tactical transport in existence. Its modern roles include airlift and airdrop, electronic surveillance, search and rescue, space-capsule recovery, helicopter refueling and aerial attack.
