An investigation has concluded that cracking occurring in the radome on some of the US-made AIM-120C air-to-air missiles carried by Taiwan’s F-16s was caused by long-term exposure to humidity and stress, the Air Force General Headquarters said yesterday.
The air force made the comments after local media reported earlier the same day that the problem with the missile — the most advanced in the Taiwanese air force — had been observed for three consecutive years.
The air force currently has 120 AIM-120C-5 and 218 AIM-120C-7 advanced medium-range air-to-air missiles (AMRAAM) in its inventory.
The “fire-and-forget” missiles are used on its 146 F-16 aircraft. The first order of AIM-120s was delivered to the air force in 2004.
Radomes, one of the eight main sections of a missile, are a pyroceramic cone at the nose that serve as a window for radar or heat-seeking electromagnetic devices inside the missile.
In a statement, the air force said it had followed US suggestions to improve rotation cycles and store the missiles in conditions that would reduce the impact of moisture on the radomes.
The US has been asked to repair the damaged missiles, the statement said, adding that the problem had not undermined national defense.
Raytheon Corp is the main manufacturer of the missile.
In a report on the 2010 AMRAAM International Users’ Conference held in Florida in May 2010, the Taiwanese air force had already identified the problem and said it had sought the assistance of the US in addressing the impact of high humidity on the missile.
The US investigation into the causes of the cracking has ruled out accidental damage caused by poor packaging or handling, as well as vandalism. The probe concluded that the high humidity in Taiwan, as well as the tremendous pressure exerted on the missiles from supersonic flight, were the principal causes of the problem.
However, the radomes on the French-made MICA and the domestically produced Tien Chien II “Sky Sword” — two other air-to-air missiles used by the Taiwanese air force — do not seem to have had similar problems, despite being exposed to the same climatic conditions, storage and rotation cycles.
According to information on Raytheon’s Web site, 36 countries worldwide have procured the AIM-120. The missile is also used on US aircraft carrier-based F/A-18 Hornet aircraft.

FREEDOM OF NAVIGATION: The UK would continue to reinforce ties with Taiwan ‘in a wide range of areas’ as a part of a ‘strong unofficial relationship,’ a paper said The UK plans to conduct more freedom of navigation operations in the Taiwan Strait and the South China Sea, British Secretary of State for Foreign, Commonwealth and Development Affairs David Lammy told the British House of Commons on Tuesday. British Member of Parliament Desmond Swayne said that the Royal Navy’s HMS Spey had passed through the Taiwan Strait “in pursuit of vital international freedom of navigation in the South China Sea.” Swayne asked Lammy whether he agreed that it was “proper and lawful” to do so, and if the UK would continue to carry out similar operations. Lammy replied “yes” to both questions. The
‘OF COURSE A COUNTRY’: The president outlined that Taiwan has all the necessary features of a nation, including citizens, land, government and sovereignty President William Lai (賴清德) discussed the meaning of “nation” during a speech in New Taipei City last night, emphasizing that Taiwan is a country as he condemned China’s misinterpretation of UN Resolution 2758. The speech was the first in a series of 10 that Lai is scheduled to give across Taiwan. It is the responsibility of Taiwanese citizens to stand united to defend their national sovereignty, democracy, liberty, way of life and the future of the next generation, Lai said. This is the most important legacy the people of this era could pass on to future generations, he said. Lai went on to discuss
MISSION: The Indo-Pacific region is ‘the priority theater,’ where the task of deterrence extends across the entire region, including Taiwan, the US Pacific Fleet commander said The US Navy’s “mission of deterrence” in the Indo-Pacific theater applies to Taiwan, Pacific Fleet Commander Admiral Stephen Koehler told the South China Sea Conference on Tuesday. The conference, organized by the Center for Strategic and International Studies (CSIS), is an international platform for senior officials and experts from countries with security interests in the region. “The Pacific Fleet’s mission is to deter aggression across the Western Pacific, together with our allies and partners, and to prevail in combat if necessary, Koehler said in the event’s keynote speech. “That mission of deterrence applies regionwide — including the South China Sea and Taiwan,” he
UNPRECEDENTED: In addition to the approved recall motions, cases such as Ma Wen-chun’s in Nantou are still under review, while others lack enough signatures The Central Election Commission (CEC) announced yesterday that a recall vote would take place on July 26, after it approved the first batch of recall motions targeting 24 Chinese Nationalist Party (KMT) lawmakers and Hsinchu Mayor Ann Kao (高虹安). Taiwan is in the midst of an unprecedented wave of mass recall campaigns, following a civil society push that echoed a call made by Democratic Progressive Party (DPP) caucus whip Ker Chien-ming (柯建銘) in January to initiate signature drives aimed at unseating KMT legislators. Under the Civil Servants Election and Recall Act (公職人員選舉罷免法), Taiwanese can initiate a recall of district-elected lawmakers by collecting
