Poor communication and surveillance capabilities have awakened interest in the military in blimps equipped with powerful sensors to conduct surveillance over disputed territory, possibly including the Diaoyutai Islands (釣魚台) and Itu Aba Island (Taiping Island, 太平島), reports are saying.
According to a recent report in Defense News, interest in acquiring such devices — known as aerostats — to increase the nation’s intelligence, surveillance and reconnaissance (ISR) capabilities increased in the wake of a Sept. 25 incident near the Diaoyutais, during which Japanese Coast Guard vessels engaged in primarily symbolic water cannon exchanges with the Coast Guard Administration (CGA) and about 40 Taiwanese fishing vessels.
Citing an unnamed military officer, the report said that the CGA and the navy had struggled to monitor developments during the clashes due largely to limited surveillance capabilities.
The military source said aerostats would be extremely useful if deployed at Pengjia Islet (彭佳嶼), located about 55km north of Keelung and 141km east of the Japan-controlled Diaoyutais, as well as on Itu Aba — the largest island in the Spratlys (Nansha Islands, 南沙群島) — which is controlled by Taiwan.
However, the source said such deployments would not necessarily constitute further militarization of the islets, because the blimps can also be used for disaster relief, surveillance of civilian maritime vessels, communication and search-and-rescue operations.
Taiwan’s current ISR capabilities in remote areas currently depend on E-2T/K “Hawkeye” early-warning aircraft. Twelve refurbished P-3C “Orion” maritime surveillance aircraft, which Taiwan has purchased from the US, are to augment those capabilities once they enter service starting next year. Taiwan is also developing a number of unmanned aerial vehicles (UAV), some of which could have the ability to conduct surveillance at sea, but remains years away from deploying satellites for maritime surveillance.
However, manned aircraft and UAVs have limited loitering time, and the latter have additional payload restrictions due to their size. As near-fixed devices, aerostats or tethered blimps with an ISR component would provide much greater coverage while being more cost-effective and easier to maintain, Defense News said.
According to the article, US-based TCOM, L.P. has recognized Taiwan’s interest in aerostats and may be actively promoting its products — more specifically, aerostats in the 17m, 22m and 28m range, which can operate at altitudes of 300m, 900m and 1,500m respectively.
Ron Davis, in charge of international development at TCOM, will reportedly visit Taiwan early next year to push for a deal, though the company has not provided confirmation.
The industry source told Defense News that the Navy was especially interested in acquiring the company’s 32m Small Aerostat Surveillance System, which comes equipped with an APG-66SR radar and can detect maritime, air and ground targets within an area of 39km2, while staying aloft for up to 14 days.
A bilateral relations fact sheet on Taiwan-US relations published on the US Department of State Web site was recently updated to remove statements saying that it acknowledged Beijing’s “one China” position, and that the US does not support Taiwanese independence. The fact sheet is produced by the department’s Bureau of East Asian and Pacific Affairs. A previous version of the document opened with the statement: “The United States and Taiwan enjoy a robust unofficial relationship.” It said the US acknowledged “the Chinese position that there is but one China and Taiwan is part of China,” and said that the US “does
INDIRECT MESSAGE? Chinese planes might have entered Taiwan’s ADIZ to take part in drills with a carrier group that was about 500km off the east coast, an analyst said The Chinese military yesterday said it had conducted live-fire drills in waters and airspace off Taiwan’s eastern and southwestern coasts from Friday to Sunday to test and upgrade its joint combat capabilities. The Eastern Theater Command of the Chinese People’s Liberation Army (PLA) posted the news on Chinese messaging platform WeChat. Over the past few days, authorities in Taiwan and Japan have observed deployments of Chinese planes and ships near Taiwan from a PLA carrier group of five destroyers, a frigate and a resupply ship led by the Liaoning aircraft carrier. The Japanese Ministry of Defense first announced on Monday last week that
China appears to have built mockups of a port in northeastern Taiwan and a military vessel docked there, with the aim of using them as targets to test its ballistic missiles, a retired naval officer said yesterday. Lu Li-shih (呂禮詩), a former lieutenant commander in Taiwan’s navy, wrote on Facebook that satellite images appeared to show simulated targets in a desert in China’s Xinjiang region that resemble the Suao naval base in Yilan County and a Kidd-class destroyer that usually docks there. Lu said he compared the mockup port to US naval bases in Yokosuka and Sasebo, Japan, and in Subic Bay
Police are investigating the death of a Formosan black bear discovered on Tuesday buried near an industrial road in Nantou County, with initial evidence indicating that it was shot accidentally by a hunter. The bear had been caught in wildlife traps at least five times before, three times since 2020. Codenamed No. 711, the bear received extensive media coverage last year after it was discovered trapped twice in less than two months in the Taichung mountains. After its most recent ensnarement last month, the bear was released in the Dandashan (丹大山) area in Nantou County’s Sinyi Township (信義). However, officials became concerned after the
