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.

In his National Day Rally speech on Sunday, Singaporean Prime Minister Lawrence Wong (黃循財) quoted the Taiwanese song One Small Umbrella (一支小雨傘) to describe his nation’s situation. Wong’s use of such a song shows Singapore’s familiarity with Taiwan’s culture and is a perfect reflection of exchanges between the two nations, Representative to Singapore Tung Chen-yuan (童振源) said yesterday in a post on Facebook. Wong quoted the song, saying: “As the rain gets heavier, I will take care of you, and you,” in Mandarin, using it as a metaphor for Singaporeans coming together to face challenges. Other Singaporean politicians have also used Taiwanese songs
NORTHERN STRIKE: Taiwanese military personnel have been training ‘in strategic and tactical battle operations’ in Michigan, a former US diplomat said More than 500 Taiwanese troops participated in this year’s Northern Strike military exercise held at Lake Michigan by the US, a Pentagon-run news outlet reported yesterday. The Michigan National Guard-sponsored drill involved 7,500 military personnel from 36 nations and territories around the world, the Stars and Stripes said. This year’s edition of Northern Strike, which concluded on Sunday, simulated a war in the Indo-Pacific region in a departure from its traditional European focus, it said. The change indicated a greater shift in the US armed forces’ attention to a potential conflict in Asia, it added. Citing a briefing by a Michigan National Guard senior
CHIPMAKING INVESTMENT: J.W. Kuo told legislators that Department of Investment Review approval would be needed were Washington to seek a TSMC board seat Minister of Economic Affairs J.W. Kuo (郭智輝) yesterday said he received information about a possible US government investment in Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) and an assessment of the possible effect on the firm requires further discussion. If the US were to invest in TSMC, the plan would need to be reviewed by the Department of Investment Review, Kuo told reporters ahead of a hearing of the legislature’s Economics Committee. Kuo’s remarks came after US Secretary of Commerce Howard Lutnick on Tuesday said that the US government is looking into the federal government taking equity stakes in computer chip manufacturers that
US President Donald Trump on Friday said that Chinese President Xi Jinping (習近平) told him China would not invade Taiwan while Trump is in office. Trump made the remarks in an interview with Fox News, ahead of talks with Russian President Vladimir Putin over Moscow’s invasion of Ukraine. “I will tell you, you know, you have a very similar thing with President Xi of China and Taiwan, but I don’t believe there’s any way it’s going to happen as long as I’m here. We’ll see,” Trump said during an interview on Fox News’ Special Report. “He told me: ‘I will never do
