Pituffik Space Base

Pituffik Space Base (/bdˈfk/ bee-doo-FEEK;[2] Greenlandic: [pitufːik]) (IATA: THU, ICAO: BGTL), formerly Thule Air Base (/tl/ or /tl/), is the United States Space Force's northernmost base, and the northernmost installation of the U.S. Armed Forces, located 750 mi (1,210 km) north of the Arctic Circle and 947 mi (1,524 km) from the North Pole on the northwest coast of the island of Greenland. Pituffik's Arctic environment includes icebergs in North Star Bay, two islands (Saunders Island and Wolstenholme Island), a polar ice sheet, and Wolstenholme Fjord – the only place on Earth where four active glaciers join together. The base is home to a substantial portion of the global network of missile warning sensors of Space Delta 4, and space surveillance and space control sensors of Space Delta 2, providing space awareness and advanced missile detection capabilities to North American Aerospace Defense Command (NORAD), the United States Space Force, and joint partners.

Pituffik Space Base is also home to the 821st Space Base Group and is responsible for space base support within the Pituffik Defense Area for the multinational population of "Team Pituffik". The base hosts the 12th Space Warning Squadron (12 SWS) which operates a Ballistic Missile Early Warning System (BMEWS) designed to detect and track ICBMs launched against North America. The base is also host to Detachment 1 of the 23rd Space Operations Squadron, part of the Space Delta 6's global satellite control network. The airfield's 10,000-foot (3,000 m) runway handles more than 3,000 US and international flights per year. The base is also home to the northernmost deep water port in the world.[3]

Pituffik Space Base has served as the regional hub for nearby installations, including Cape Atholl (LORAN station), Camp Century (Ice Cap Camp), Camp TUTO (Ice Cap Approach Ramp and Airstrip), Sites 1 and 2 (Ice Cap Radar Stations), P-Mountain (radar and communications site), J-Site (BMEWS), North and South Mountains (research sites), and a research rocket firing site.[not verified in body] It also was essential in the construction and resupply of High Arctic weather stations, including CFS Alert (Alert Airport) and Station Nord.

History edit

Location and original population edit

In 1818, Sir John Ross's expedition made first contact with nomadic Inuktun in the area. James Saunders's expedition aboard HMS North Star was marooned in North Star Bay 1849–50 and named landmarks.[4] Robert Peary built a support station by a protected harbor at the foot of iconic Mount Dundas in 1892. It served as a base camp for his expeditions and attracted a permanent population. In 1910 explorer Knud Rasmussen established a missionary and trading post there. He called the site "Thule" after classical ultima Thule; the Inuit called it Umanaq ("heart-shaped"), and the site is commonly called "Dundas" today. The United States abandoned its territorial claims in the area in 1917 in connection with the purchase of the Virgin Islands. Denmark assumed control of the village in 1937.

A cluster of huts known as Pituffik ("the place the dogs are tied") stood on the wide plain where the base was built in 1951. (A main base street was named Pituffik Boulevard.) The affected locals moved to Thule. However, in 1953 the USAF planned to construct an air defense site near that village, and in order to limit contact with soldiers, the Danish government relocated "Old Thule" with about 130 inhabitants to a newly constructed, modern village 60 miles (97 km) north, known as Qaanaaq, or "New Thule". In a Danish Supreme Court judgment of 28 November 2003 the move was considered an expropriative intervention. During the proceedings it was recognized by the Danish government that the movement was a serious interference and an unlawful act against the local population. The Thule tribe was awarded damages of 500,000 kroner, and the individual members of the tribe who had been exposed to the transfer were granted compensation of 15,000 or 25,000 each. A Danish radio station continued to operate at Dundas, and the abandoned houses remained. The USAF only used that site for about a decade, and it has since returned to civilian use.

Knud Rasmussen was the first to recognize the Pituffik plain as ideal for an airport. USAAF Colonel Bernt Balchen, who built Sondrestrom Air Base, knew Rasmussen and his idea. Balchen led a flight of two Consolidated PBY Catalina flying boats to Thule on 24 August 1942 and then sent a report advocating an air base to USAAF chief Henry "Hap" Arnold. However, the 1951 air base site is a few miles inland from the original 1946 airstrip and across the bay from the historical Thule settlement, to which it is connected by an ice road. The joint Danish-American defense area, designated by treaty, also occupies considerable inland territory in addition to the air base itself.[5]

World War II edit

After the German occupation of Denmark on 9 April 1940, Henrik Kauffmann, Danish Ambassador to the United States, made an agreement "In the name of the king" with the United States, authorizing the United States to defend the Danish colonies on Greenland from German aggression – this agreement faced Kauffmann with a charge of high treason by the protectorate Government. The first US-sponsored installations at Thule were established after the US Secretary of State Cordell Hull and the defected Danish Minister to the United States Henrik Kauffmann signed The Agreement relating to the Defense of Greenland in Washington, D.C., on the symbolically chosen date of 9 April 1941. The treaty, denounced by the Danish government, allowed the United States to operate military bases in Greenland "for as long as there is agreement" that the threat to North America existed. Beginning in the summer of 1941, the US Coast Guard and the War Department established weather and radio stations at Narsarsuaq Airport (Bluie West-1), Sondrestrom Air Base (Bluie West-8), Ikateq (Bluie East Two), and Gronnedal (Bluie West-9). In 1943 the Army Air Forces set up weather stations Scoresbysund (Bluie East-3) on the east coast around the southern tip of Greenland, and Thule (Bluie West-6) to be operated by Danish personnel. Many other sites were set up, but BW-6, isolated in the far North, was then of very minor importance.[6]

Joint weather station edit

After liberation, Denmark ratified the Kauffmann treaty but began efforts to take over US installations. Nonetheless, in summer 1946, the radio and weather station was enhanced with a gravel airstrip and an upper-air (balloon) observatory. This was part of an American-Canadian initiative to construct joint weather stations in the High Arctic. This station was under joint US-Danish operation. The location changed from the civilian village at Thule (Dundas) to mainland Pituffik. In 1946–1951, the airstrip played an important role in Arctic resupply, aerial mapping, research, and search-and rescue.

The ratification of the treaty in 1951 did not change much, except that the Danish national flag must be side by side with the US national flag on the base.

Modern air base edit

In 1949, Denmark joined NATO (North Atlantic Treaty Organization) and abandoned its attempt to remove the United States bases. By the outbreak of the Korean War next year, the USAF embarked on a global program of base-building in which Thule (at the time) would be considered the crown jewel owing to its location across the Pole from the USSR, as well as its merit of being the northernmost port to be reliably resupplied by ship. Thule became a key point in American nuclear retaliation strategy. Strategic Air Command (SAC) bombers flying over the Arctic presented less risk of early warning than using bases in the United Kingdom. Defensively, Thule could serve as a base for intercepting bomber attacks along the northeastern approaches to Canada and the US.

A board of Air Force officers headed by Gordon P. Saville made a recommendation to pursue a base at Thule in November 1950. It was subsequently supported by the Joint Chiefs of Staff and approved by President Truman. To replace the agreement entered into during World War II between the US and Denmark, a new agreement with respect to Greenland was ratified on 27 April 1951 (effective on 8 June 1951). At the request of NATO, the agreement became a part of the NATO defense program. The pact specified that the two nations would arrange for the use of facilities in Greenland by NATO forces in defense of the NATO area known as the Greenland Defense Area.

Thule Air Base was constructed in secret under the code name Operation Blue Jay, but the project was made public in September 1952. Construction for Thule Air Base began in 1951 and was completed in 1953. The construction of Thule is said to have been comparable in scale to the enormous effort required to build the Panama Canal. [7] The United States Navy transported the bulk of men, supplies, and equipment from the naval shipyards in Norfolk, Virginia. On 6 June 1951 an armada of 120 ships sailed from Naval Station Norfolk. On board were 12,000 men and 300,000 tons of cargo. They arrived at Thule on 9 July 1951. Construction, aided by continuous daylight in summer, took place around the clock. The workers lived on board the ships until quarters were built. Once they moved into the quarters, the ships returned home.

On 16 June 1951, the base was accidentally discovered by French cultural anthropologist and geographer Jean Malaurie and his Inuit friend Kutikitsoq, on their way back from the geomagnetic North Pole.[8]

Strategic Air Command edit

Originally established as a Strategic Air Command installation, Thule would periodically serve as a dispersal base for B-36 Peacemaker and B-47 Stratojet aircraft during the 1950s, as well as providing an ideal site to test the operability and maintainability of these weapon systems in extreme cold weather. Similar operations were also conducted with B-52 Stratofortress aircraft in the 1950s and 1960s.

In 1954, the 378 m (1,240 ft) Globecom Tower, a tower for military radio communication, was built at Northmountain. At the time of its completion it was the third tallest human-made structure on earth[citation needed] and the tallest structure north of the Arctic Circle in the Western hemisphere.

 
Reconnaissance route from Thule Air Base to Soviet Union

In the winter of 1956/57 three KC-97 tankers and alternately one of two RB-47H aircraft made polar flights to inspect Soviet defenses. Five KC-97s prepared for flight with engines running in temperatures of −50 °F (−46 °C) in order to ensure three could achieve airborne status. After a two-hour head start, a B-47 would catch up with them at the northeast coastline of Greenland where two would offload fuel to top off the B-47's tanks (the third was an air spare). The B-47 would then fly seven hours of reconnaissance, while the tankers would return to Thule, refuel, and three would again fly to rendezvous with the returning B-47 at northeast Greenland. The B-47 averaged ten hours and 4,500 km (2,800 mi) in the air, unless unpredictable weather closed Thule. In that case the three tankers and the B-47 had to additionally fly to one of three equidistant alternates: England, Alaska, or Labrador. All of this sometimes took place in moonless, 24-hour Arctic darkness, December through February. These flights demonstrated the capabilities of the US Strategic Air Command to Soviet Anti-Air Defense.

In 1959, the airbase was the main staging point for the construction of Camp Century, some 150 mi (240 km) from the base.[9] Carved into the ice, and powered by a nuclear reactor, PM-2A Camp Century was officially a scientific research base, but in reality was the site of the top secret Project Iceworm. The camp operated from 1959 until 1967.

In the late 1950s, the DEW 1 to 4 were built as "weather stations". Thule Air Base would act as a supply station for the DYE bases.[citation needed]

Aerospace defense edit

In 1957 construction began on four Nike Missile sites around the base, and they and their radar systems were operational by the end of 1958.

In 1961, a Ballistic Missile Early Warning System (BMEWS) radar was constructed at "J-Site," 21 km (13 mi) northeast of main base. BMEWS was developed by the RCA Corporation in order to provide North America warning of a transpolar missile attack from the Russian mainland and submarine-launched missiles from the Arctic and North Atlantic oceans. At this time, Thule was at its peak with a population of about 10,000. Starting in July 1965, there was a general downsizing of activities at Thule. The base host unit, the 4683d Air Defense Wing, was discontinued. By January 1968, the population of Thule was down to 3,370. On 21 January 1968, a B-52G bomber carrying four nuclear weapons crashed just outside Thule – see below.

Thule is the location where the fastest recorded sea level surface wind speed in the world was measured, when a peak speed of 333 km/h (207 mph) was recorded on 8 March 1972, immediately prior to the instrument's destruction.[10][11]

Air Force Space Command from 1982 to 2019 edit

Thule became an Air Force Space Command base in 1982. Today Thule is home to the 821st Air Base Group, which exercises Air Base support responsibilities within the Thule Defense Area. The base hosts the 12th Space Warning Squadron (21st Operations Group, 21st Space Wing), a Ballistic Missile Early Warning Site designed to detect and track ICBMs launched against North America. Missile warning and space surveillance information flows to NORAD command centers located at Peterson Space Force Base, Colorado. Thule is also host to Detachment 1 of the 23rd Space Operations Squadron, part of the 50th Space Wing's global satellite control network, as well as operating many new weapons systems. In addition, the airfield boasts a 3,047 by 42 m (9,997 by 138 ft) asphalt runway, with 3,000 US and international flights per year.

A delegation from the NATO Parliamentary Assembly visited Thule in early September 2010 and were told by the base commander that, at that time (summer), approximately 600 personnel were serving at Thule, a mix of mostly US and Danish active duty personnel and contractors.[12]

There is only a brief period each year in the summer when sea ice thins sufficiently to send supply ships to the base. The US sends one heavy supply ship each summer in what is called Operation Pacer Goose.[13]

Space Force Command from 2020 edit

In 2020, Thule was formally reorganized under the control of the United States Space Force. On 6 April 2023, Thule Air Base was renamed Pituffik Space Base, reflecting its status as a Space Force base and the native name for the region.[2]

Remote tracking station edit

Thule Tracking Station (TTS) is operated by Pituffik Space Base, using the callsign POGO. The station 76°30′57″N 68°36′0″W / 76.51583°N 68.60000°W / 76.51583; -68.60000) is a U.S. Space Force installation in Greenland, near the base, and has a Remote Tracking Station (callsign: Polar Orbiting Geophysical Observatory (POGO)) of the Satellite Control Network.[20]

It was originally the classified 6594th Test Wing's Operating Location 5 designated by Air Force Systems Command on 15 October 1961: the station was operational on 30 March 1962, with "transportable antenna vans parked in an old Strategic Air Command bomb assembly building."[20] The permanent RTS equipment was emplaced in 1964,[20] and a communications terminal was emplaced on Pingarssuit Mountain—Thule Site N-32[21] (moved to Thule Site J in 1983.[20]

Accidents edit

C-124 plane crash (1954) edit

In 1954 a Douglas C-124C Globemaster II operated by the US Air Force crashed on approach to the air base, killing ten people.[23]

B-52 nuclear bomber crash (1968) edit

On 21 January 1968, a B-52G Stratofortress from the 380th Strategic Aerospace Wing, Plattsburgh Air Force Base, New York, on a secret airborne nuclear alert crashed and burned on the ice near Thule Air Base. The impact detonated the high explosives in the primary units of all four of the B28 nuclear bombs it carried, but nuclear and thermonuclear reactions did not take place due to the PAL and fail-safe mechanisms in the weapons, thus preventing the actual detonation of the weapons themselves. The resulting fire caused extensive radioactive contamination.[24] More than 700 Danish civilians and US military personnel worked under hazardous conditions, the former without protective gear, to clean up the nuclear waste.[25] In 1987, nearly 200 of the Danish workers tried unsuccessfully to sue the United States. Kaare Ulbak, chief consultant to the Danish National Institute of Radiation Hygiene, said Denmark had carefully studied the health of the Thule workers and found no evidence of increased mortality or cancer.[26][27][28]

The Pentagon maintained that all four weapons had been destroyed. Although many of the details of the accident are still classified, some information was released by the US authorities under the Freedom of Information Act. After reviewing these files, an investigative reporter from BBC News claimed in May 2007 that the USAF was unable to account for one of the weapons.[25] In 2009, the assertions of the BBC were refuted by a Danish report after a review of the available declassified documentation.[29]

Airlines and destinations edit

Airlines edit

As of 2010, Air Greenland provided commercial service to Pituffik to the Moriusaq Heliport, Qaanaaq Airport,[30] and Savissivik Heliport.[30] It also charters to Copenhagen Airport and Kangerlussuaq.

Cargo Shipping edit

Ocean Transportation is provided by Schuyler Line Navigation Company, a US Flag Ocean Carrier. Schuyler Line operates under government contract to supply sustainment and building supplies to the Base.[citation needed]

Geography edit

Pituffik has a tundra climate (ET) with long, severely cold winters lasting most of the year and short and cool summers. Precipitation is very low year round, but peaks during summer. The structures of the base are built on permafrost which makes them vulnerable to the effects of climate change.[31]

linksHistory editLocation and original population edit In 1818 Sir John Ross s expedition made first contact with nomadic Inuktun in the area James Saunders s expedition aboard HMS North Star was marooned in North Star Bay 1849 50 and named landmarks 4 Robert Peary built a support station by a protected harbor at the foot of iconic Mount Dundas in 1892 It served as a base camp for his expeditions and attracted a permanent population In 1910 explorer Knud Rasmussen established a missionary and trading post there He called the site Thule after classical ultima Thule the Inuit called it Umanaq heart shaped and the site is commonly called Dundas today The United States abandoned its territorial claims in the area in 1917 in connection with the purchase of the Virgin Islands Denmark assumed control of the village in 1937 A cluster of huts known as Pituffik the place the dogs are tied stood on the wide plain where the base was built in 1951 A main base street was named Pituffik Boulevard The affected locals moved to Thule However in 1953 the USAF planned to construct an air defense site near that village and in order to limit contact with soldiers the Danish government relocated Old Thule with about 130 inhabitants to a newly constructed modern village 60 miles 97 km north known as Qaanaaq or New Thule In a Danish Supreme Court judgment of 28 November 2003 the move was considered an expropriative intervention During the proceedings it was recognized by the Danish government that the movement was a serious interference and an unlawful act against the local population The Thule tribe was awarded damages of 500 000 kroner and the individual members of the tribe who had been exposed to the transfer were granted compensation of 15 000 or 25 000 each A Danish radio station continued to operate at Dundas and the abandoned houses remained The USAF only used that site for about a decade and it has since returned to civilian use Knud Rasmussen was the first to recognize the Pituffik plain as ideal for an airport USAAF Colonel Bernt Balchen who built Sondrestrom Air Base knew Rasmussen and his idea Balchen led a flight of two Consolidated PBY Catalina flying boats to Thule on 24 August 1942 and then sent a report advocating an air base to USAAF chief Henry Hap Arnold However the 1951 air base site is a few miles inland from the original 1946 airstrip and across the bay from the historical Thule settlement to which it is connected by an ice road The joint Danish American defense area designated by treaty also occupies considerable inland territory in addition to the air base itself 5 World War II edit After the German occupation of Denmark on 9 April 1940 Henrik Kauffmann Danish Ambassador to the United States made an agreement In the name of the king with the United States authorizing the United States to defend the Danish colonies on Greenland from German aggression this agreement faced Kauffmann with a charge of high treason by the protectorate Government The first US sponsored installations at Thule were established after the US Secretary of State Cordell Hull and the defected Danish Minister to the United States Henrik Kauffmann signed The Agreement relating to the Defense of Greenland in Washington D C on the symbolically chosen date of 9 April 1941 The treaty denounced by the Danish government allowed the United States to operate military bases in Greenland for as long as there is agreement that the threat to North America existed Beginning in the summer of 1941 the US Coast Guard and the War Department established weather and radio stations at Narsarsuaq Airport Bluie West 1 Sondrestrom Air Base Bluie West 8 Ikateq Bluie East Two and Gronnedal Bluie West 9 In 1943 the Army Air Forces set up weather stations Scoresbysund Bluie East 3 on the east coast around the southern tip of Greenland and Thule Bluie West 6 to be operated by Danish personnel Many other sites were set up but BW 6 isolated in the far North was then of very minor importance 6 Joint weather station edit After liberation Denmark ratified the Kauffmann treaty but began efforts to take over US installations Nonetheless in summer 1946 the radio and weather station was enhanced with a gravel airstrip and an upper air balloon observatory This was part of an American Canadian initiative to construct joint weather stations in the High Arctic This station was under joint US Danish operation The location changed from the civilian village at Thule Dundas to mainland Pituffik In 1946 1951 the airstrip played an important role in Arctic resupply aerial mapping research and search and rescue The ratification of the treaty in 1951 did not change much except that the Danish national flag must be side by side with the US national flag on the base Modern air base edit In 1949 Denmark joined NATO North Atlantic Treaty Organization and abandoned its attempt to remove the United States bases By the outbreak of the Korean War next year the USAF embarked on a global program of base building in which Thule at the time would be considered the crown jewel owing to its location across the Pole from the USSR as well as its merit of being the northernmost port to be reliably resupplied by ship Thule became a key point in American nuclear retaliation strategy Strategic Air Command SAC bombers flying over the Arctic presented less risk of early warning than using bases in the United Kingdom Defensively Thule could serve as a base for intercepting bomber attacks along the northeastern approaches to Canada and the US A board of Air Force officers headed by Gordon P Saville made a recommendation to pursue a base at Thule in November 1950 It was subsequently supported by the Joint Chiefs of Staff and approved by President Truman To replace the agreement entered into during World War II between the US and Denmark a new agreement with respect to Greenland was ratified on 27 April 1951 effective on 8 June 1951 At the request of NATO the agreement became a part of the NATO defense program The pact specified that the two nations would arrange for the use of facilities in Greenland by NATO forces in defense of the NATO area known as the Greenland Defense Area Thule Air Base was constructed in secret under the code name Operation Blue Jay but the project was made public in September 1952 Construction for Thule Air Base began in 1951 and was completed in 1953 The construction of Thule is said to have been comparable in scale to the enormous effort required to build the Panama Canal 7 The United States Navy transported the bulk of men supplies and equipment from the naval shipyards in Norfolk Virginia On 6 June 1951 an armada of 120 ships sailed from Naval Station Norfolk On board were 12 000 men and 300 000 tons of cargo They arrived at Thule on 9 July 1951 Construction aided by continuous daylight in summer took place around the clock The workers lived on board the ships until quarters were built Once they moved into the quarters the ships returned home On 16 June 1951 the base was accidentally discovered by French cultural anthropologist and geographer Jean Malaurie and his Inuit friend Kutikitsoq on their way back from the geomagnetic North Pole 8 Strategic Air Command edit nbsp 74th Fighter Interceptor Squadron F 89s Thule Air Base Greenland 1955Originally established as a Strategic Air Command installation Thule would periodically serve as a dispersal base for B 36 Peacemaker and B 47 Stratojet aircraft during the 1950s as well as providing an ideal site to test the operability and maintainability of these weapon systems in extreme cold weather Similar operations were also conducted with B 52 Stratofortress aircraft in the 1950s and 1960s In 1954 the 378 m 1 240 ft Globecom Tower a tower for military radio communication was built at Northmountain At the time of its completion it was the third tallest human made structure on earth citation needed and the tallest structure north of the Arctic Circle in the Western hemisphere nbsp Reconnaissance route from Thule Air Base to Soviet UnionIn the winter of 1956 57 three KC 97 tankers and alternately one of two RB 47H aircraft made polar flights to inspect Soviet defenses Five KC 97s prepared for flight with engines running in temperatures of 50 F 46 C in order to ensure three could achieve airborne status After a two hour head start a B 47 would catch up with them at the northeast coastline of Greenland where two would offload fuel to top off the B 47 s tanks the third was an air spare The B 47 would then fly seven hours of reconnaissance while the tankers would return to Thule refuel and three would again fly to rendezvous with the returning B 47 at northeast Greenland The B 47 averaged ten hours and 4 500 km 2 800 mi in the air unless unpredictable weather closed Thule In that case the three tankers and the B 47 had to additionally fly to one of three equidistant alternates England Alaska or Labrador All of this sometimes took place in moonless 24 hour Arctic darkness December through February These flights demonstrated the capabilities of the US Strategic Air Command to Soviet Anti Air Defense In 1959 the airbase was the main staging point for the construction of Camp Century some 150 mi 240 km from the base 9 Carved into the ice and powered by a nuclear reactor PM 2A Camp Century was officially a scientific research base but in reality was the site of the top secret Project Iceworm The camp operated from 1959 until 1967 In the late 1950s the DEW 1 to 4 were built as weather stations Thule Air Base would act as a supply station for the DYE bases citation needed Aerospace defense edit In 1957 construction began on four Nike Missile sites around the base and they and their radar systems were operational by the end of 1958 In 1961 a Ballistic Missile Early Warning System BMEWS radar was constructed at J Site 21 km 13 mi northeast of main base BMEWS was developed by the RCA Corporation in order to provide North America warning of a transpolar missile attack from the Russian mainland and submarine launched missiles from the Arctic and North Atlantic oceans At this time Thule was at its peak with a population of about 10 000 Starting in July 1965 there was a general downsizing of activities at Thule The base host unit the 4683d Air Defense Wing was discontinued By January 1968 the population of Thule was down to 3 370 On 21 January 1968 a B 52G bomber carrying four nuclear weapons crashed just outside Thule see below Thule is the location where the fastest recorded sea level surface wind speed in the world was measured when a peak speed of 333 km h 207 mph was recorded on 8 March 1972 immediately prior to the instrument s destruction 10 11 Air Force Space Command from 1982 to 2019 edit nbsp Aurora over Thule Air Base in 2017Thule became an Air Force Space Command base in 1982 Today Thule is home to

Peterson Space Force Base Colorado Thule is also host to Detachment 1 of the 23rd Space Operations Squadron part of the 50th Space Wing s global satellite control network as well as operating many new weapons systems In addition the airfield boasts a 3 047 by 42 m 9 997 by 138 ft asphalt runway with 3 000 US and international flights per year A delegation from the NATO Parliamentary Assembly visited Thule in early September 2010 and were told by the base commander that at that time summer approximately 600 personnel were serving at Thule a mix of mostly US and Danish active duty personnel and contractors 12 There is only a brief period each year in the summer when sea ice thins sufficiently to send supply ships to the base The US sends one heavy supply ship each summer in what is called Operation Pacer Goose 13 Space Force Command from 2020 edit In 2020 Thule was formally reorganized under the control of the United States Space Force On 6 April 2023 Thule Air Base was renamed

B 52 nuclear bomber crash 1968 edit Main article B 52 Crash at Thule Air Base On 21 January 1968 a B 52G Stratofortress from the 380th Strategic Aerospace Wing Plattsburgh Air Force Base New York on a secret airborne nuclear alert crashed and burned on the ice near Thule Air Base The impact detonated the high explosives in the primary units of all four of the B28 nuclear bombs it carried but nuclear and thermonuclear reactions did not take place due to the PAL and fail safe mechanisms in the weapons thus preventing the actual detonation of the weapons themselves The resulting fire caused extensive radioactive contamination 24 More than 700 Danish civilians and US military personnel worked under hazardous conditions the former without protective gear to clean up the nuclear waste 25 In 1987 nearly 200 of the Danish workers tried unsuccessfully to sue the United States Kaare Ulbak chief consultant to the Danish National Institute of Radiation Hygiene said Denmark had carefully studied the health of the Thule workers and found no evidence of increased mortality or cancer 26 27 28 The Pentagon maintained that all four weapons had been destroyed Although many of the details of the accident are still classified some information was released by the US authorities under the Freedom of Information Act After reviewing these files an investigative reporter from BBC News claimed in May 2007 that the USAF was unable to account for one of the weapons 25 In 2009 the assertions of the BBC were refuted by a Danish report after a review of the available declassified documentation
