Runways at seven airports are to be widened to make them more resilient to a potential missile attack from China, a source from the Ministry of National Defense said yesterday.
Ministry officials and US advisers made the decision after reviewing data from Han Kuang military exercises, the source said, adding that runways would be widened to 60m.
The adjustment would allow runways to more quickly be repaired so that fighter jets could take off and land, and would make the runways usable by B-52 bombers and large transport aircraft, the source said.

In a combat scenario, China would likely target Taiwan’s air bases, so the ministry is preparing by widening runways and performing annual repair drills, the source said.
The runway of the Ching Chuan Kang (清泉崗) Air Base in Taichung, which was originally built with the assistance of the US military, is 60m wide, as it was built to accommodate B-52 bombers. It was decided that runways at Taiwan’s other bases, which are 45m to 50m in width, should be widened to match that of Ching Chuan Kang, the source said.
“If runways are hit by surface-to-surface missiles or other weapons during wartime, takeoff and landing operations might be paralyzed — so we need to be prepared for that,” the source said.
Assuming that a runway is struck by Chinese ballistic missiles with an accuracy of less than 50m and a destruction radius of 25m, six missiles would give China an 80 percent chance of destroying the runway, the source said.
Potentially, China could destroy a runway with two missiles fired in short succession at a target with a radius of 100m, the source said.
“It’s not guaranteed that China would hit its target, but we must be ready to restore a runway should it be hit, and widening runways is the best way to accomplish that,” the source said.
The main runways of air bases have shoulders and buffer zones about 7.5m to 15m in width, which could be quickly reinforced by widening them, the source said.
Air force personnel have undergone runway repair training in the US, as well as at Ching Chuan Kang, the source said.
“During the last drill, the army’s unexploded ordinance disposal team used 18kg of TNT to blast holes in the base’s taxiway, simulating an enemy attack,” the source said. “The blast created a 2m-deep hole with a radius of 20m that teams used for the drill, which involved removing foreign objects, laying fiberglass repair kits, backfilling the crater and compacting it.”
During the drill, a minimum operating strip with a length of 1.5km and a width of 15m was opened to allow the resumption of aircraft takeoffs and landings in the shortest possible time, the source said.
Air force personnel have shortened runway repair times from four hours for one or large crater repair operations, down to 2.5 hours, the source said.
Super Typhoon Kong-rey is the largest cyclone to impact Taiwan in 27 years, the Central Weather Administration (CWA) said today. Kong-rey’s radius of maximum wind (RMW) — the distance between the center of a cyclone and its band of strongest winds — has expanded to 320km, CWA forecaster Chang Chun-yao (張竣堯) said. The last time a typhoon of comparable strength with an RMW larger than 300km made landfall in Taiwan was Typhoon Herb in 1996, he said. Herb made landfall between Keelung and Suao (蘇澳) in Yilan County with an RMW of 350km, Chang said. The weather station in Alishan (阿里山) recorded 1.09m of
NO WORK, CLASS: President William Lai urged people in the eastern, southern and northern parts of the country to be on alert, with Typhoon Kong-rey approaching Typhoon Kong-rey is expected to make landfall on Taiwan’s east coast today, with work and classes canceled nationwide. Packing gusts of nearly 300kph, the storm yesterday intensified into a typhoon and was expected to gain even more strength before hitting Taitung County, the US Navy’s Joint Typhoon Warning Center said. The storm is forecast to cross Taiwan’s south, enter the Taiwan Strait and head toward China, the Central Weather Administration (CWA) said. The CWA labeled the storm a “strong typhoon,” the most powerful on its scale. Up to 1.2m of rainfall was expected in mountainous areas of eastern Taiwan and destructive winds are likely
The Central Weather Administration (CWA) yesterday at 5:30pm issued a sea warning for Typhoon Kong-rey as the storm drew closer to the east coast. As of 8pm yesterday, the storm was 670km southeast of Oluanpi (鵝鑾鼻) and traveling northwest at 12kph to 16kph. It was packing maximum sustained winds of 162kph and gusts of up to 198kph, the CWA said. A land warning might be issued this morning for the storm, which is expected to have the strongest impact on Taiwan from tonight to early Friday morning, the agency said. Orchid Island (Lanyu, 蘭嶼) and Green Island (綠島) canceled classes and work
KONG-REY: A woman was killed in a vehicle hit by a tree, while 205 people were injured as the storm moved across the nation and entered the Taiwan Strait Typhoon Kong-rey slammed into Taiwan yesterday as one of the biggest storms to hit the nation in decades, whipping up 10m waves, triggering floods and claiming at least one life. Kong-rey made landfall in Taitung County’s Chenggong Township (成功) at 1:40pm, the Central Weather Administration (CWA) said. The typhoon — the first in Taiwan’s history to make landfall after mid-October — was moving north-northwest at 21kph when it hit land, CWA data showed. The fast-moving storm was packing maximum sustained winds of 184kph, with gusts of up to 227kph, CWA data showed. It was the same strength as Typhoon Gaemi, which was the most
