have ten LC-130s in its inventory. These would include upgrades of four LC-130 aircraft in-service with the unit plus three new aircraft and three that would be transferred from the U.S. Navy. Air National Guard estimates of the savings to be realized by consolidating the operation in the hands of the 109th Airlift Wing ranged from US $5 million to US$15 million a year. The actual transition to Air Guard control began in March 1996. By 1999, the United States Navy had transferred military support operations for Antarctica over to the United States Air Force and its contractor Raytheon Polar Services. Operation Deep Freeze was managed by the U.S. Air Force and Air National Guard members of Air National Guard Detachment 13, a subordinate unit which administratively reported directly to the Air National Guard Readiness Center (ANGRC) at Andrews Air Force Base in Maryland, and operationally reported to United States Pacific Command (USPACOM) in Honolulu, Hawaii. Upon its deactivation in 2005, the detachment consisted of a full-time officer (Commander) and four full-time non-commissioned officers (Logistics, Communications, Security Forces, and Information Management) which remained in New Zealand year-round. Operational command now belongs to Commander, Thirteenth Air Force as part of USPACOM. In 2005, through the office of the Secretary of Defense, the commander of U.S. Pacific Command was designated to support the Joint Task Force Support Forces Antarctica, Operation Deep Freeze. CDRUSPACOM delegated this joint operation to the Commander, Pacific Air Forces, who then delegated primary responsibility for execution of the JTF SFA operation to the Commander, 13th Air Force. Current status United States civilian and scientific operations on the Antarctic continent are overseen by the United States Antarctic Program as well as the National Science Foundation. Military support missions flown from Christchurch International Airport are conducted during the Antarctic summer (late September to early March) each year by The 109th Airlift Wing Scotia New York. The Ski equipped LC-130 Hercules is the backbone of Operation Deep Freeze. LC-130 Hercules aircraft provide the logistical movement of cargo to remote operating locations on the continent. These aircraft are augmented by the United States Coast Guard icebreaker USCGC Polar Star, the Air Force Materiel Command, and the Military Sealift Command. The United States Air Force 13th Air Expeditionary Group deploys to Christchurch, New Zealand during the operational season.
