On February 4, 2023, ahigh-altitude balloon of Chinese origin intrude U.S. airspace and was shot down by the F-22, causing various diplomatic issues.

From January 28 to February 4, 2023, the Chinese balloon crossed through North America, passing over Alaska, western Canada, and the contiguous United States. At first, the American and Canadian militaries presumed the balloon was a surveillance device, while the Chinese government claimed it was a civilian airship used for meteorological research that was blown off course by winds.[1] Then balloon passed over Montana by February 1 and Missouri by February 3 before being shot down by the U.S. Air Force off the coast of South Carolina on February 4, on orders from President Joe Biden.[2]

The event strained China–United States relations, leading to the abrupt postponement of an upcoming diplomatic trip to Beijing by United States Secretary of State Antony Blinken.[3] United States officials also alleged other balloons had entered United States airspace in recent years,[3] and on February 3 alleged another Chinese balloon was floating over Latin America.[4]

Background

Further information: History of military ballooning

The use of surveillance balloons as a military technology dates to the 19th and 20th centuries, when they were employed by various militaries, including the United States and Soviet Union during the Cold War.[5] Despite being rendered mostly obsolete by the advent of maneuverable and stealthy surveillance satellites and drones, balloons retained some advantages, such as a lower cost of production and deployment.[5][6] As of 2021, China's fleet of intelligence, surveillance, target acquisition, and reconnaissance (ISTAR) satellites had over 260 systems, second only to the United States.[5] During the 2023 incident, a U.S. defense official stated that the alleged surveillance balloon had "limited additive value from an intelligence collection perspective".[5]

According to United States defense officials, there have been several instances of Chinese balloons, suspected of surveillance activity, entering United States airspace in recent years in Florida, Guam, and Hawaii;[7][8][3] in such instances China was able to recover the balloons, and none of the incursions persisted for as long as the 2023 incident, which overflew the North American continent coast to coast.

In 2020, a similar balloon was sighted in Sendai, Japan, which at the time was not identified as being of Chinese origin.[9][10][11] In February 2022, several balloons were spotted off the coast of Taiwan, which the Taiwanese Ministry of National Defense noted are likely for meteorological observations for the Eastern Theater Command of the People's Liberation Army and posed no immediate security threat.[12]

Incident

Comparison with size of estimated balloon.

Description

The balloon carries an underslung payload described as a "technology bay" estimated to be the size of "two or three school buses", on which was mounted solar panels for power.[a] The envelope of the balloon itself is "much larger", according to a U.S. official cited by CBS News.[7] The same official described the craft as featuring a rudder for limited steering. Years earlier in Japan, a balloon of a cross-type payload bay was reported, adding two propellers mounted on the side of the chassis, possibly for more controllability.[10]

Detection

On February 2, 2023, the United States Department of Defense (DoD) and the Canadian Department of National Defence (DND) announced that the North American Aerospace Defense Command (NORAD) was tracking a high-altitude surveillance balloon believed to belong to China.[13][14] The balloon was then flying at an altitude of 60,000 feet (18 kilometers) over the northern United States, and the DoD said that the balloon did not pose a threat to civil aviation or people on the ground.[15][16] According to national security and aerospace experts cited by The Washington Post, the balloon shares characteristics with other high-altitude balloons used by other nations for meteorology, telecommunications, and research.[17]

According to the United States, the balloon entered its airspace above the Aleutian Islands on January 28, and entered Canadian airspace above the Northwest Territories on January 30.[3] The balloon then crossed back into the United States in northern Idaho on January 31 and Montana on February 1,[3] where it was spotted over Billings.[14][15] Montana is the location of multiple nuclear missile installations, including Malmstrom Air Force Base, one of three U.S. Air Force bases from which intercontinental ballistic missiles (ICBMs) are operated, raising suspicions that the balloon had been launched to surveil said nuclear installations.[14] A meteorological researcher calculated a possible trajectory along this path using the HYSPLIT atmospheric model, consistent with data on prevailing westerlies from China to Montana.[18] The balloon was spotted above northwest Missouri, near Kansas City, on February 3.[15]

On February 3, the United States DoD stated that a second alleged Chinese surveillance balloon was flying over Latin America.[19] Unconfirmed sightings of the balloon were reported from Colombia, Venezuela, and Costa Rica.[20][21][22][23]

Downing

On February 4, the balloon drifted to the Carolinas.[24] The FAA closed airspace over the area.[25] A ground stop was ordered on the coast at Myrtle Beach International Airport, Charleston International Airport, and Wilmington International Airport.[26][27][28] Military aircraft were reported to be over the Carolinas.[29] U.S. officials later stated that this was in preparation for the eventual downing of the balloon over the Atlantic.[3]

According to the U.S. military, the balloon was successfully shot down by a single AIM-9X air-to-air missile, fired from a F-22 Raptor off the coast of Surfside Beach, South Carolina at 2:39 PM local time.[30] The shootdown was the first kill recorded by an F-22 aircraft, and was speculated to be the highest-altitude air-to-air kill in history.[b][31]

Debris recovery

The debris from the balloon was dispersed over an area of seven square miles (18 square kilometers), and collection efforts were initiated for further inspection.[32]

American defense officials considered shooting the balloon down but initially decided not to due to the risk of debris injuring civilians on the ground.[33] A meeting was convened between United States Secretary of Defense Lloyd Austin, Chairman of the Joint Chiefs of Staff General Mark Milley, NORTHCOM/NORAD Commander General Glen D. VanHerck, and other military commanders.[13] President Joe Biden was advised by officials not to shoot it down because debris could hit people on the ground.[13] The balloon was monitored by manned aircraft sent by NORAD, including the early warning aircraft Boeing E-3 Sentry (commonly known as AWACS), a reconnaissance RC-135 from Nellis Air Force Base,[33] and F-22 Raptor aircraft from Langley Air Force Base.[34] Secretary of State Antony Blinken first postponed his scheduled diplomatic trip to China, then canceled on February 3, in response. Coincidentally, numerous people mistook the United States high-altitude research balloon HBAL617 as the Chinese balloon. HBAL617 was able to be seen on flight tracking apps, while the Chinese balloon was not.[35][36]

In response to questions regarding the situation, on February 4, President Joe Biden stated that the U.S. would "take care of it."[37] Later that day, U.S. officials disclosed that three days earlier he had granted permission to down the balloon.[3] At 2:39 PM local time, the balloon was downed by two F-22 fighter jets using an AIM-9X Sidewinder missile,[34][38] with the United States announcing that it will recover and analyze the remnants that splashed down in the Atlantic.[3] The guided-missile destroyer USS Oscar Austin (DDG-79), guided-missile cruiser USS Philippine Sea (CG-58), and amphibious warship USS Carter Hall (LSD-50) were tasked with retrieving the balloon wreckage alongside assistance from U.S. Coast Guard cutters and helicopters, U.S. Navy divers, and FBI counterintelligence agents.[39][40]

Canada

Canadian officials and Global Affairs Canada summoned the Chinese ambassador to Canada, Cong Peiwu, to Ottawa while the Department of National Defence announced it was monitoring the situation alongside the United States through NORAD.[41][42] A statement from the Canadian Armed Forces said there was no threat to Canadians, and Minister of Foreign Affairs Mélanie Joly would remain in contact with Secretary of State Antony Blinken.[43]

China

A spokeswoman for the Chinese Foreign Ministry Mao Ning said: "It is a civilian airship used for research, mainly meteorological, purposes. Affected by the Westerlies and with limited self-steering capability, the airship deviated far from its planned course."[44]

The state-controlled China Daily newspaper reported: "To spy on the U.S. with a balloon, one must both fall far behind to use a 1940s technology and be advanced enough to control its flight across the ocean. Those fabricating the lie are only exposing their ignorance."[33]

Following the downing, the Chinese government issued a statement saying it will protect the legitimate interests of the relevant enterprises, and reserve the right to take further actions while criticizing the United States for "an obvious overreaction and a serious violation of international practice."[3]
