Beechcraft C-12 Huron
The C-12 Huron is the military designation for a series of twin-engine turboprop aircraft based on the Beechcraft Super King Air and Beechcraft 1900. C-12 variants are used by the United States Air Force, United States Army, United States Navy and United States Marine Corps. These aircraft are used for various duties, including embassy support, medical evacuation, as well as passenger and light cargo transport. Some aircraft are modified with surveillance systems for various missions, including the Cefly Lancer, Guardrail and Project Liberty programs.
==Design and development==
The first C-12A models entered service with the U.S. Army in 1974 and was used as a liaison and general personnel transport. The aircraft was essentially an "off-the-shelf" Super King Air 200, powered by the type's standard Pratt & Whitney Canada PT6A-41 engines.
The U.S. Navy followed suit in 1979, ordering a version of the Super King Air A200C (modified with a 52 inch by 52 inch cargo door from the Super King Air 200C), designating it the UC-12B, for logistics support between Naval and Marine Corps air stations, air facilities, and other activities, both in CONUS and overseas. The cabin can readily accommodate cargo, passengers or both. It is also equipped to accept litter patients in medical evacuation missions. Through 1982, the Navy ordered 64 of these aircraft.〔
A U.S. Air Force variant of the plane for surveillance roles primarily over Afghanistan and Iraq was the MC-12W Liberty. For that variant, Beechcraft built the basic plane and then sent it to Greenville, Texas where sophisticated intelligence, surveillance and reconnaissance (ISR) equipment was installed by L-3 Communications Missions Integration.〔(Lifesaving Liberty )〕 As of 2013 the Liberty program had exceeded 300,000 combat flying hours. The MC-12W was rushed into combat as a supplemental surveillance and signals intelligence asset; since its first combat mission on 10 June 2009, the aircraft flew 400,000 combat hours in 79,000 combat sorties, aiding in the kill or capture of “more than 8,000 terrorists” and uncovering 650 weapons caches. With its roles taken over by the growing MQ-9 Reaper fleet, the Air Force decided to divest itself of the 41 Liberty aircraft and turn them over to the U.S. Army and U.S. Special Operations Command, which will be completed by October 2015.〔(Beale AFB farewells MC-12 as spy plane moves to Army and SOCOM ) - Flightglobal.com, 25 September 2015〕 The Air Force's final MC-12W deployment in support of Operation Enduring Freedom ended on 13 October 2015.〔(Homecoming: Beale Airmen return from final MC-12W deployment ) - AF.mil, 14 October 2015〕
