The Ministry of National Defense has unveiled a proposed NT$9.67 billion (US$312.4 million) program to buy 635 lightweight anti-uncrewed aerial vehicle (UAV) systems capable of taking over, jamming and GPS data spoofing drones.
The draft proposal to purchase the systems over the next three years has not yet been finalized and must be approved by the legislature.
The systems must be capable of passively detecting more than 10 targets within a 4km zone with an imagery refresh rate of more than once per second and engaging drones operating on frequencies between 433 megahertz and 5.8 gigahertz to a range of 2km, the ministry said.

They must be small enough to be transported on light vehicles including tactical and civilian vehicles, as well as small boats, and require no more than 15 minutes to set up with one or two operators, it said.
The manufacturers must deliver a first batch of 242 systems to the military for testing within 180 days of being notified that it has been awarded a contract, and a second batch of 393 systems within 180 days of passing performance tests, it said.
Supplementary material attached to the notification showed that the program would provide 242 systems to the army, 213 systems to the navy, 72 systems to the air force and 108 systems to the Information, Communications and Electronic Force Command, it said.
Funding would be drawn from annual special budgets designated for next year, 2027 and 2028, the ministry said.
An expert speaking on condition of anonymity criticized aspects of the proposed counter-UAV program, saying the ministry might need to re-examine its suppositions about defensive drone warfare.
As specified, the anti-drone systems would not provide a sufficient detection and engagement range to maintain a continuous area of defense, or the numbers needed to fend off drone swarms, they said.
In addition, deploying “cybertakeover” capabilities and GPS spoofing as a means to defeat hostile UAVs presupposes that friendly operators have already compromised the command signals utilized by enemy drone navigation and guidance systems, the source said.
That means the systems would be ineffective should they encounter hostile drones that used unknown command frequencies or signals, or an encryption system that has not been deciphered, they said.
The military should also ensure that the systems are cost-effective, they said.
Sufficient resources must be directed toward developing algorithms that can rapidly defeat enemy encryption systems and a constantly updated library of enemy UAV signals, if cybertakeover and GPS-spoofing are to remain viable countermeasures against hostile drones, the source said.
‘NO SECURITY RISK’: The Railway Bureau reassured the public that the technicians’ activities were limited to technical guidance and did not involve sensitive systems The Railway Bureau yesterday said it had invited eight Chinese technicians to assist with an airport MRT construction project. The bureau issued the confirmation after an Internet user said Chinese nationals had entered the construction zone of Taiwan Taoyuan International Airport’s Terminal 3 project. They asked why “individuals from an enemy state” were allowed access to such a major national infrastructure project, which raised serious concerns over Taiwan’s industrial safety, sensitive systems and information security. The bureau’s Northern Region Engineering Branch Office said subcontractor Taiwan Handle Industrial Co (台灣手把工業) of the Taoyuan airport MRT’s “Contract No. CU05 Project A14 Station Civil, MEP &
A US uncrewed surface vessel (USV) encountered multiple Chinese warships during an autonomous transit of the Taiwan Strait, US defense company Seasats said in a statement on Wednesday. Seasats announced that a Lightfish USV had completed the first autonomous transit of the Taiwan Strait. Over five days, the USV traversed the entire length of the Strait while constantly monitoring surface vessel traffic, the company said. The Lightfish encountered multiple Chinese warships, one of which was a Chinese People’s Liberation Army Navy (PLAN) Type 056 corvette, it said. The Chinese vessels were operating “well within Taiwan’s exclusive economic zone without transmitting their identity via the
GREATER REACH? Auto parts and wood products would face tariffs of up to 15%, matching those targeting the EU, Japan and South Korea, Vice Premier said The US has announced that preferential tariff treatment for Taiwan’s non-semiconductor Section 232 goods would take effect retroactively from May 1, the Executive Yuan said yesterday. The US government yesterday posted a notice on the Federal Register’s public inspection Web site previewing tariff concessions for Taiwan under a memorandum of understanding (MOU) on Taiwan-US investment after two months of negotiations. The MOU signed on Jan. 15 stipulated three major preferential tariff arrangements: a 15 percent “reciprocal” tariff rate for Taiwan without stacking most-favored nation (MFN) rates; preferential Section 232 treatment for semiconductors and related products; and preferential Section 232 treatment for non-semiconductor
TIT-FOR-TAT: The US allegedly revoked the visa of a Chinese national working at Xinhua News Agency in the US in response to Beijing’s expulsion of Vivian Wang The Presidential Office yesterday condemned China for expelling a New York Times correspondent from Beijing following the newspaper’s interview with President William Lai (賴清德), saying the move highlighted Beijing’s suppression of press freedom and its threat to international news media. Taiwan has noted a series of recent incidents in which Beijing used similar tactics to “threaten and pressure international media outlets and journalists,” Presidential Office spokeswoman Karen Kuo (郭雅慧) said in a statement. “This concerns not only press freedom and freedom of expression, but also the safety of journalists, and Taiwan and relevant partners are paying close attention to the situation,” she
