The US’ approval of exports of three advanced air defense missile systems to Taiwan signified NATO’s goodwill toward the nation, a Taiwanese defense expert said.
The US Defense Security Cooperation Agency on Friday announced the US$1.16 billion sale of the National Advanced Surface-to-Air Missile System (NASAMS) and the US$828 million sale of AN/TPS-77 and AN/TPS-78 radar turnkey systems.
The NASAMS is a network that uses ground-launched Air Intercept Missile (AIM)-120 Advanced Medium-Range Air-to-Air Missiles (AMRAAM) to intercept hostile aircraft, drones and cruise missiles.

Su Tzu-yun (蘇紫雲), director of defense strategy and resources at the state-funded Institute for National Defense and Security Research, said that Taiwanese first expressed interest in the NASAMS to their US counterparts in 2022.
The US could not transfer an air defense system it designed in partnership with Norway without the Scandinavian country’s permission, and by extension, NATO, he said on Saturday, adding that the acquisition of the systems significantly boosts Taiwan’s defense capabilities.
The NASAMS can detect aerial objects at 300km, engage targets at 40km to 60km, and include counter jamming capabilities, he said.
The mobile systems provide defensive firepower for strategically important installations, he said, adding that their ability to use AIM-120 and AIM-9 missiles significantly increases the military’s defensive capabilities.
More weapons such as NASAMS dedicated to defeating medium and low-altitude targets are needed to defend strategic installations after China demonstrated its capability to deploy up to six vertical launching system-equipped warships in waters around Taiwan, he said.
The NASAMS represent the first asymmetric-warfare-capable systems furnished by US President Joe Biden, defense expert Mei Fu-hsing (梅復興) said, adding that each system is a self-contained unit composed of a fire control center, radar and launchers.
The systems can be operated by company-sized units, he said.
The radar turnkey and missile systems would likely bolster Taiwan’s ability to defend Taipei by detecting threats posed by stealth fighters and drones, military experts said.
The AN/TPS-77 radar system, which has a range of 470km, is used for long-range air surveillance and is especially good at detecting small aerial objects, Institute for National Defense and Security Research associate research fellow Shu Hsiao-huang (舒孝煌) said.
The AN/TPS-78 radar system has an instrumental range of 444km and can better identify low-altitude cruise missiles and drones, he said.
Retired air force officer Chou Yu-ping (周宇平) said the surface-to-air missile systems would be deployed in Taipei to guard the capital against cruise missiles and fighter jets.
Sharing the intelligence gathered by the AN/MPQ-64F1 Sentinel radar systems equipped on the surface-to-air missile systems with the air force’s integrated network would be crucial, Chou said.
The missile systems in the newly disclosed sales are expected to replace the HAWK surface-to-air missile system, which covers medium-range and low-to-medium altitude objects in Taiwan’s air defense, Shu said.
The Sentinel radar systems can identify targets within a range of 120km, and the shooting range of the 123 AMRAAM is 50km, he said.
The new missile systems can be used to launch several types of missiles, such as the AIM-120 and AIM-9X models which are made by same manufacturer, as well as the IRIS-T medium range infrared homing missiles, he said.
If the missile systems can also be deployed with the indigenous Tien Chien I (天劍一, “Sky Sword 1”) and Tien Chien II (天劍二, “Sky Sword II”) missiles, that would further improve the country’s defense independence, he said.
Commenting on a reported plan to retire the air force’s 35mm and 20mm anti-aircraft twin cannons, Shu said they should remain in service, as it is not cost-effective to use missiles to shoot down uncrewed flying objects.
AGING: While Japan has 22 submarines, Taiwan only operates four, two of which were commissioned by the US in 1945 and 1946, and transferred to Taiwan in 1973 Taiwan would need at least 12 submarines to reach modern fleet capabilities, CSBC Corp, Taiwan chairman Chen Cheng-hung (陳政宏) said in an interview broadcast on Friday, citing a US assessment. CSBC is testing the nation’s first indigenous defense submarine, the Hai Kun (海鯤, Narwhal), which is scheduled to be delivered to the navy next month or in July. The Hai Kun has completed torpedo-firing tests and is scheduled to undergo overnight sea trials, Chen said on an SET TV military affairs program. Taiwan would require at least 12 submarines to establish a modern submarine force after assessing the nation’s operational environment and defense
Yangmingshan National Park authorities yesterday urged visitors to respect public spaces and obey the law after a couple was caught on a camera livestream having sex at the park’s Qingtiangang (擎天崗) earlier in the day. The Shilin Police Precinct in Taipei said it has identified a suspect and his vehicle registration number, and would summon him for questioning. The case would be handled in accordance with public indecency charges, it added. The couple entered the park at about 11pm on Thursday and began fooling around by 1am yesterday, the police said, adding that the two were unaware of the park’s all-day live
The coast guard today said that it had disrupted "illegal" operations by a Chinese research ship in waters close to the nation and driven it away, part of what Taipei sees a provocative pattern of China's stepped up maritime activities. The coast guard said that it on Thursday last week detected the Chinese ship Tongji (同濟號), which was commissioned only last year, 29 nautical miles (54km) southeast of the southern tip of Taiwan, although just outside restricted waters. The ship was observed lowering ropes into the water, suspected to be the deployment of scientific instruments for "illegal" survey operations, and the coast
A former soldier and an active-duty army officer were yesterday indicted for allegedly selling classified military training materials to a Chinese intelligence operative for a total of NT$79,440. The Taipei District Prosecutors’ Office indicted Chen Tai-yin (陳泰尹) and Lee Chun-ta (李俊達) for contravening the National Security Act (國家安全法) and the Anti-Corruption Act (貪污治罪條例). Chen left the military in September 2013 after serving alongside then-staff sergeant Lee, now an army lieutenant, at the 21st Artillery Command of the army’s Sixth Corps from 2011 to 2013, according to the indictment. Chen met a Chinese intelligence operative identified as “Wang” (王) through a friend in November
