<p><b>Operation Deep Freeze</b> is the code name for a series of <a href="United_States" title="United States">United States</a> missions to <a href="Antarctica" title="Antarctica">Antarctica</a>, beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on. (There was an initial operation before <a href="Richard_E._Byrd" title="Richard E. Byrd">Admiral Richard Byrd</a> proposed 'Deep Freeze'). Given the continuing and constant US presence in Antarctica since that date, "Operation Deep Freeze" has come to be used as a general term for US operations in that continent, and in particular for the regular missions to resupply US Antarctic bases, coordinated by the <a href="Military_of_the_United_States" class="mw-redirect" title="Military of the United States">United States military</a>. Task Force 199 was involved.
</p><p>For a few decades the missions were led by the United States Navy, though the Air National Guard and National Science Foundation are also important parts of the missions. In Antarctica, when the polar dawn starts late in the year things begin warming up and the mission usually runs from late in the year to early the next year before the months of darkness and cold return. During that time bases will over-winter until the next year and Deep Freeze mission.

<p>The <a href="U.S._Navy" class="mw-redirect" title="U.S. Navy">U.S. Navy</a> already had a record of earlier exploration in Antarctica. As early as 1839, Captain <a href="Charles_Wilkes" title="Charles Wilkes">Charles Wilkes</a> led the <a href="United_States_Exploring_Expedition%2C_1838-1842" class="mw-redirect" title="United States Exploring Expedition, 1838-1842">first U.S. Naval expedition</a> into Antarctic waters. In 1929, Admiral <a href="Richard_E._Byrd" title="Richard E. Byrd">Richard E. Byrd</a> established a naval base at <a href="Little_America_(exploration_base)" title="Little America (exploration base)">Little America</a> I, led <a href="Richard_Evelyn_Byrd" class="mw-redirect" title="Richard Evelyn Byrd">an expedition</a> to explore further inland, and conducted the first flight over the South Pole. From 1934 to 1935, the <a href="Richard_Evelyn_Byrd" class="mw-redirect" title="Richard Evelyn Byrd">second Byrd Expedition</a> explored much further inland and also "wintered over". The third Byrd Expedition in 1940 charted the <a href="Ross_Sea" title="Ross Sea">Ross Sea</a>.
</p><p>Byrd was instrumental in the Navy's <a href="Operation_Highjump" title="Operation Highjump">Operation Highjump</a> after <a href="World_War_II" title="World War II">World War II</a> from 1946 to 1947, which charted most of the Antarctic coastline. In 1948, Commander <a href="Finn_Ronne" title="Finn Ronne">Finn Ronne</a> led an expedition that photographed over 450,000 square miles (1.1 million km<sup>2</sup>) by air. Then in 1954–55, the <a href="Icebreaker" title="Icebreaker">icebreaker</a> <a href="USS_Atka_(AGB-3)" class="mw-redirect" title="USS Atka (AGB-3)">USS <i>Atka</i></a> made a scouting expedition for future landing sites and bays.

<p>The impetus behind Operation Deep Freeze I was the <a href="International_Geophysical_Year" title="International Geophysical Year">International Geophysical Year</a> 1957–58. IGY as it was known was a collaborative effort among forty nations to carry out earth science studies from the <a href="North_Pole" title="North Pole">North Pole</a> to the <a href="South_Pole" title="South Pole">South Pole</a> and at points in between.

Their goal was to advance world knowledge of Antarctic <a href="Hydrography" title="Hydrography">hydrography</a> and <a href="Weather" title="Weather">weather systems</a>, <a href="Glacial_motion" title="Glacial motion">glacial movements</a>, and <a href="Marine_life" title="Marine life">marine life</a>.
</p><p>The <a href="U.S._Navy" class="mw-redirect" title="U.S. Navy">U.S. Navy</a> was charged with supporting the U.S. scientists for their portion of the IGY studies. Rear Admiral <a href="Richard_E._Byrd" title="Richard E. Byrd">Richard E. Byrd</a>, a veteran of four previous Antarctic Expeditions, was appointed as officer in charge of the expedition.
</p><p>In 1955, Task Force 43, commanded by Rear Admiral <a href="George_J._Dufek" title="George J. Dufek">George J. Dufek</a>, was formed to provide logistical support for the expedition.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> Operation Deep Freeze I prepared a permanent research station and paved the way for more exhaustive research in later Deep Freeze operations. The expedition transpired over the Antarctic summer of November 1955 to April 1956, and was filmed by the <a href="U.S._Navy" class="mw-redirect" title="U.S. Navy">U.S. Navy</a> and <a href="Walt_Disney_Studios_(division)" title="Walt Disney Studios (division)">Walt Disney Studios</a>.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> For having designed the emblem of Task Force 43, <a href="Walt_Disney" title="Walt Disney">Walt Disney</a> became an honorary member of the expedition.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>

<li>USS <i>YOG-70</i>, aviation fuel carrier</li></ul>
<div style="clear:left;" class=""></div>
<p>The ships of the task force were supplemented by a specially trained Navy <a href="Construction_Battalion" class="mw-redirect" title="Construction Battalion">Construction Battalion</a>, formed at the Naval Construction Battalion Center at <a href="Davisville%2C_Rhode_Island" title="Davisville, Rhode Island">Davisville, Rhode Island</a> and several aircraft.
</p><p>On October 31, 1956, at 8:34 p.m. local time, the first aircraft ever to touch down at the South Pole skied to a halt atop the Antarctic ice sheet at 90 degrees South latitude. The U.S. Navy R4D, was piloted by Lieutenant Commander (LCDR) Conrad C. "Gus" Shinn USN and included officer Frederick Ferrara. Immediately after the plane halted--with engines running to avoid a freeze-up (a practice still followed to this day)--U.S. Navy Adm. George J. Dufek., commander of Operation Deep Freeze, stepped out onto the ice, along with pilot Douglas Cordiner, to plant the stars and stripes at the Pole. They were the first to stand there since Briton <a href="Robert_Falcon_Scott" title="Robert Falcon Scott">Robert Falcon Scott</a> did more than 40 years before. Norwegian <a href="Roald_Amundsen" title="Roald Amundsen">Roald Amundsen</a> had beaten Scott in his race to the Pole. Amundsen's party survived the 800-mile return trip, Scott's did not.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> This flight was one part of the expeditions mounted for the IGY. This was not only the first aircraft to land at the South Pole, it was also the first time that Americans had ever set foot on the South Pole. The aircraft was named <i>Que Sera, Sera</i> after a <a href="Que_Sera%2C_Sera_(Whatever_Will_Be%2C_Will_Be)" title="Que Sera, Sera (Whatever Will Be, Will Be)">popular song</a> and is now on display at the <a href="National_Naval_Aviation_Museum" title="National Naval Aviation Museum">Naval Aviation Museum</a> in <a href="Pensacola%2C_Florida" title="Pensacola, Florida">Pensacola, Florida</a>. This marked the beginning of the establishment of the first permanent base, by airlift, at the South Pole (today known as the <a href="Amundsen%E2%80%93Scott_South_Pole_Station" title="Amundsen–Scott South Pole Station">Amundsen–Scott South Pole Station</a>) to support the International Geophysical Year. It was commissioned on January 1, 1957. The mission's second base, <a href="Byrd_Station" title="Byrd Station">Byrd Station</a>, was a (former) research station in West Antarctica established by the US Navy for Operation Deep Freeze II during the International Geophysical Year.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> The original station ("Old Byrd") lasted about four years before it began to collapse under the snow. Construction of a second underground station in a nearby location began in 1960, and it was used until 1972. The station was then converted into a summer-only field camp until it was abandoned in 2004–05. The United States Antarctic Program airfield, built to service Operation Deep Freeze (first mission) was later named Williams Field or Willy Field.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup>
</p>
<div class="mw-heading mw-heading2"><h2 id="Subsequent_developments">Subsequent developments</h2></div>
<p>The Operation Deep Freeze activities were succeeded by "Operation Deep Freeze II", and so on. In 1960, the year of the fifth mission, codenames began to be based on the year (e.g., "Operation Deep Freeze 60").<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup>
</p><p>Operation Deep Freeze I (1955-56), Operation Deep Freeze II (1956-57), and Operation Deep Freeze III (57-58), prepared the United States for the start of the IGY on 1 July 1957.<sup id="cite_ref-:2_9-0" class="reference"><a href="#cite_note-:2-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> The Mobile Construction Battalion for ODF I established Little America base in Kainan Bay and a base at McMurdo, and for ODF II built Byrd and the South Pole Station.<sup id="cite_ref-:2_9-1" class="reference"><a href="#cite_note-:2-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup>

</p><p>In early 1996, the <a href="National_Guard_of_the_United_States" class="mw-redirect" title="National Guard of the United States">United States National Guard</a> announced that the <a href="109th_Airlift_Wing" title="109th Airlift Wing">109th Airlift Wing</a> at <a href="Schenectady_County_Airport" title="Schenectady County Airport">Schenectady County Airport</a> in <a href="Scotia%2C_New_York" title="Scotia, New York">Scotia, New York</a> was slated to assume that entire mission from the <a href="United_States_Navy" title="United States Navy">United States Navy</a> in 1999. The Antarctic operation would be fully funded by the National Science Foundation. The 109th expected to add approximately 235 full-time personnel to support that operation. The decision to switch from Naval leadership to National Guard was one of a cost-saving measure due to post cold war budget cuts.<sup id="cite_ref-14" class="reference"><a href="#cite_note-14"><span class="cite-bracket">[</span>14<span class="cite-bracket">]</span></a></sup>
</p><p>The possibility of the <a href="Air_National_Guard" title="Air National Guard">Air National Guard</a> assuming operational control of the mission had first emerged in 1988. The 109th Airlift Wing had been notified that, almost overnight, one of the <a href="Distant_Early_Warning_Line" title="Distant Early Warning Line">Distant Early Warning Line</a> (DEW) radar sites that it supported in Greenland was going to be shut down. The other sites would soon follow, and the 109th would be largely out of business because its primary mission had ended. The unit had been informally keeping tabs on Navy LC-130 operations supporting the National Science Foundation in Antarctica. Because of its aging aircraft fleet and extensive depot maintenance period, the United States Navy asked if the 109th could provide limited emergency <a href="Search_and_rescue" title="Search and rescue">search and rescue</a> (SAR) capability for two years to support Operation Deep Freeze, which the Air Guard accepted. At that time, it had no thought of taking over the mission. The 109th believed it to be an exercise in futility for its aircraft to deploy to the Antarctic to merely wait for emergency SAR missions, so it asked if the Navy could help carry cargo to the <a href="South_Pole" title="South Pole">South Pole</a>. The Navy resisted at first because its procedures and cargo configurations differed from those of the Air Guard, but eventually it agreed. The main mission of the U.S. Navy and Air National Guard <a href="C-130_Hercules" class="mw-redirect" title="C-130 Hercules">C-130s</a> was to airlift fuel and supplies to the National Science Foundation's South Pole Station so that its personnel could survive the isolation of the long Antarctic winter, which lasted from February to October.
</p><p>An Air National Guard working group had been formed to study the idea in 1990. The following year, a dialog began among the Air National Guard, the <a href="Air_Staff_(United_States)" title="Air Staff (United States)">Air Staff</a>, and the United States Navy. Among other issues, it was difficult at first for the Air Guard to convince the Air Staff to commit long term resources to an area of the world that had not been declared a warfighting region because of international treaties. The Air Guard had supported military operations in <a href="Greenland" title="Greenland">Greenland</a> and the Arctic (including classified U.S. Navy operations) since the mid-1970s with the ski-equipped C-130s of the <a href="109th_Airlift_Wing" title="109th Airlift Wing">109th Airlift Wing</a>. It convinced Headquarters, <a href="United_States_Air_Force" title="United States Air Force">United States Air Force</a> that it was not in the nation's best interest to abandon the capability to achieve quick and reliable air access to both polar regions.
</p>
<p>In March 1993, the U.S. Navy hosted a two-day workshop with representatives of the National Science Foundation, Air National Guard, and other interested parties to explore logistics support options for the operation. A draft concept of operations had been prepared by the Air Directorate of the National Guard Bureau in 1993. In February 1996, a commitment was made to transfer the Operation Deep Freeze mission and all <a href="LC-130_Hercules" class="mw-redirect" title="LC-130 Hercules">LC-130H</a> aircraft operating within the <a href="United_States_Department_of_Defense" title="United States Department of Defense">U.S. Department of Defense</a> to the Air National Guard. In September 1996, senior officers from the 109th Airlift Wing briefed the National Guard Bureau on their concept of operations and the status of their preparations to implement Operation Deep Freeze.
</p><p>Under the transition plan which they had developed, the Air National Guard would continue to augment the United States Navy during the October 1996 – March 1997 operating season for the <a href="United_States_Antarctic_Program" title="United States Antarctic Program">United States Antarctic Program</a>. At the end of the October 1997 – March 1998 season, the Air National Guard would assume command of the program. During the third year of the transition program (October 1998 to March 1999), the U.S. Navy would augment the ANG before the latter took over the entire program the following year. There would be seven LC-130s in theater. They would stage from <a href="Christchurch_International_Airport" class="mw-redirect" title="Christchurch International Airport">Christchurch International Airport</a> in <a href="Christchurch" title="Christchurch">Christchurch</a>, New Zealand, to <a href="McMurdo_Station" title="McMurdo Station">McMurdo Station</a>, Antarctica. Traditional Guardsmen, technicians, and the cadre of <a href="Active_Guard_Reserve" title="Active Guard Reserve">Active Guard Reservists</a> specifically brought on board to support Operation Deep Freeze would all be involved in the mission. When fully transitioned to the Air National Guard, the 109th Airlift Wing would have ten <a href="Lockheed_LC-130" title="Lockheed LC-130">LC-130s</a> 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 <a href="United_States_dollar" title="United States dollar">US $</a>5 million to US$15 million a year. The actual transition to Air Guard control began in March 1996.
</p><p>By 1999, the United States Navy had transferred military support operations for Antarctica over to the United States Air Force and its contractor <a href="Raytheon_Polar_Services" class="mw-redirect" title="Raytheon Polar Services">Raytheon Polar Services</a>. Operation Deep Freeze was managed by the <a href="United_States_Air_Force" title="United States Air Force">U.S. Air Force</a> and <a href="Air_National_Guard" title="Air National Guard">Air National Guard</a> members of Air National Guard Detachment 13, a subordinate unit which administratively reported directly to the Air National Guard Readiness Center (ANGRC) at <a href="Andrews_Air_Force_Base" title="Andrews Air Force Base">Andrews Air Force Base</a> in <a href="Maryland" title="Maryland">Maryland</a>, and operationally reported to <a href="United_States_Pacific_Command" class="mw-redirect" title="United States Pacific Command">United States Pacific Command</a> (USPACOM) in <a href="Honolulu%2C_Hawaii" class="mw-redirect" title="Honolulu, Hawaii">Honolulu, Hawaii</a>. 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.<sup id="cite_ref-15" class="reference"><a href="#cite_note-15"><span class="cite-bracket">[</span>15<span class="cite-bracket">]</span></a></sup> 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, <a href="United_States_Pacific_Air_Forces" class="mw-redirect" title="United States Pacific Air Forces">Pacific Air Forces</a>, who then delegated primary responsibility for execution of the JTF SFA operation to the Commander, <a href="13th_Air_Force" class="mw-redirect" title="13th Air Force">13th Air Force</a>.
