Taiwan would have to fight off a Chinese blockade and invasion for about a month before the US could successfully airlift or sealift forces or munitions to support it, war games organized by a US congressional committee on Wednesday showed.
The finding was from a defense industrial base simulation carried out by the US House Select Committee on the Chinese Communist Party (CCP) and the think tank Center for Strategic and International Studies (CSIS).
CSIS defense expert Mark Cancian said Taiwan’s mountainous terrain and two relatively narrow coastal strips make it “a difficult island to capture.”

Aside from its terrain, Taiwan’s capital, and most of its industry and military forces are located in the north, he said, adding that this presents China with “a tough choice.”
China could either invade the north, “into the teeth of the Taiwanese defenses,” but also very close to Taipei, or in the south, where it is much easier to get ashore, but “you have to fight your way up the entire island,” he said.
In the event of an attack on the south, China would try to get its forces ashore and quickly capture a port or airfield, while the US and Japan would race to sink Chinese amphibious ships so they could no longer support their forces in Taiwan, Cancian said.
“In most of the [simulations], we won that race, but at a very high cost,” Cancian added.
If Chinese forces did gain a foothold in the south, the resulting campaign would look like Italy in World War II, with Chinese and Taiwanese troops fighting “river line by river line, ridge line by ridge line,” he said.
Alternately, in simulations of an attack on the north, where most of Taiwan’s defenses are, “it ends up being a huge battle outside of Taipei,” Cancian said, adding that it would be “tough” for China to capture the city.
One lesson from the war game was the value of anti-ship missiles, Cancian said.
In the next couple of years, “I think the most effective thing you could do is to give Taiwan 500 Harpoon missiles,” he said.
Such missiles would be stationed in Taiwan and put on mobile launchers; they would be able to hit Chinese ships within range without having to put US troops on the ground, he said.
“The other lesson is that once the fighting begins, it’s impossible to get any forces or reinforcements onto Taiwan,” Cancian said.
Since Chinese forces would surround Taiwan, the US would not be able to get an airlift or sealift to the nation “at least for the first three or four weeks,” he said.
“Taiwan would have to fight at least the first month, and maybe the first two months, with whatever it starts out with,” he added.
The war simulation was also attended by US House Select Committee on the CCP Chairman John Moolenaar, ranking member Raja Krishnamoorthi and Armed Services Committee Vice Chairman Rob Wittman.
In April, Wittman was one of four US representatives who sent a letter urging the US House Appropriations Committee to allocate US$165 million to expedite the delivery of Harpoon missiles to Taiwan.
The lawmakers said the missiles should be delivered within the “Davidson window,” a term referring to the 2021-to-2027 period when former US Indo-Pacific Command head Admiral Phil Davidson believed a Chinese invasion of Taiwan would be most likely.
Last year, Bloomberg reported that Taiwan had purchased 400 land-launched Harpoon missiles from the US, completing a deal that the US Congress approved in 2020.
The Chinese-language Liberty Times (sister paper of the Taipei Times) in September reported that Taiwan had received an unspecified number of Harpoon missiles, part of a total of 128 missiles and 32 launchers that would be delivered by the end of 2026.
However, in Wednesday’s exercise, Wittman said that there is “no way” the US could catch up with China’s industrial capacity by 2027.
China has a shipbuilding capacity 232 times greater than the US, as well as advantages in producing regular and long-range munitions, he said.
The US should therefore not view “exquisite” weapons platforms — costly, advanced weapons produced in small numbers — as the solution, and should instead focus on contingency strategies that could be more effective in the near term, he added.
The military has spotted two Chinese warships operating in waters near Penghu County in the Taiwan Strait and sent its own naval and air forces to monitor the vessels, the Ministry of National Defense (MND) said. Beijing sends warships and warplanes into the waters and skies around Taiwan on an almost daily basis, drawing condemnation from Taipei. While the ministry offers daily updates on the locations of Chinese military aircraft, it only rarely gives details of where Chinese warships are operating, generally only when it detects aircraft carriers, as happened last week. A Chinese destroyer and a frigate entered waters to the southwest
The eastern extension of the Taipei MRT Red Line could begin operations as early as late June, the Taipei Department of Rapid Transit Systems said yesterday. Taipei Rapid Transit Corp said it is considering offering one month of free rides on the new section to mark its opening. Construction progress on the 1.4km extension, which is to run from the current terminal Xiangshan Station to a new eastern terminal, Guangci/Fengtian Temple Station, was 90.6 percent complete by the end of last month, the department said in a report to the Taipei City Council's Transportation Committee. While construction began in October 2016 with an
NON-RED SUPPLY: Boosting the nation’s drone industry is becoming increasingly urgent as China’s UAV dominance could become an issue in a crisis, an analyst said Taiwan’s drone exports to Europe grew 41.7-fold from 2024 to last year, with demand from Ukraine’s fight against Russian aggression the most likely driver of growth, a study showed. The Institute for Democracy, Society and Emerging Technology (DSET) in a statement on Wednesday said it found that many of Taiwan’s uncrewed aerial vehicle (UAV) sales were from Poland and the Czech Republic. These countries likely transferred the drones to Ukraine to aid it in its fight against the Russian invasion that started in 2022, it said. Despite the gains, Taiwan is not the dominant drone exporter to these markets, ranking second and fourth
Japanese Prime Minister Sanae Takaichi’s comment last year on Tokyo’s potential reaction to a Taiwan-China conflict has forced Beijing to rewrite its invasion plans, a retired Japanese general said. Takaichi told the Diet on Nov. 7 last year that a Chinese naval blockade or military attack on Taiwan could constitute a “survival-threatening situation” for Japan, potentially allowing Tokyo to exercise its right to collective self-defense. Former Japan Ground Self-Defense Force general Kiyofumi Ogawa said in a recent speech that the remark has been interpreted as meaning Japan could intervene in the early stages of a Taiwan Strait conflict, undermining China’s previous assumptions
