National Sun Yat-sen University and CSBC Corp, Taiwan have been working to develop and build a search-and-rescue submersible, a research team said yesterday.
The submersible, which is being developed by the university’s Institute of Undersea Technology, is equipped with the institute’s fiber-optic instrumentation towed system and locally built sonar systems, the institute said.
Its development team, led by Wang Chua-chin (王朝欽), said that the first variant of the dual-seat submersible completed an 8m underwater test in Kaohsiung Harbor on July 15.

“We plan to test the submersible in Tainan’s Anping Harbor (安平漁港) and the harbor in Pingtung County’s Liouciou (琉球) next year,” Wang said, adding that the vehicle would undergo underwater pressure testing at a depth of 20m.
Ultimately, the vehicle would have a maximum operating depth of 3,000m, the institute said.
National Applied Research Laboratories’ Taiwan Ocean Research Institute Director Wang Chao-chang (王兆璋) said that the nation has always had the capability of manufacturing underwater equipment.
Following a failed bid in 2013 to rent foreign equipment for research and development purposes, funding was diverted to local research and development efforts under the Taiwan National Energy Program, Wang Chao-chang said.
The prototype weighs 3.7 tonnes and cost NT$3 million (US$105,237), the institute said, adding that the project started in 2018, when then-CSBC vice president Han Yu-lin (韓育霖) donated the vehicle’s hull and part of its internal equipment.
The institute was part of a search and rescue operation off the coast of Hualien County last month looking for the wreckage of a crashed F-16 jet. The images the institute captured 1,000m underwater helped the air force locate the wreckage.
The jet had gone missing on Nov. 17 two minutes after taking off from Hualien Air Force Base for a nighttime training exercise. Colonel Chiang Cheng-chih (蔣正志) died in the crash.
More than half of the bamboo vipers captured in Tainan in the past few years were found in the city’s Sinhua District (新化), while other districts had smaller catches or none at all. Every year, Tainan captures about 6,000 snakes which have made their way into people’s homes. Of the six major venomous snakes in Taiwan, the cobra, the many-banded krait, the brown-spotted pit viper and the bamboo viper are the most frequently captured. The high concentration of bamboo vipers captured in Sinhua District is puzzling. Tainan Agriculture Bureau Forestry and Nature Conservation Division head Chu Chien-ming (朱健明) earlier this week said that the
NAMING SPAT: The foreign ministry called on Denmark to propose an acceptable solution to the erroneous nationality used for Taiwanese on residence permits Taiwan has revoked some privileges for Danish diplomatic staff over a Danish permit that lists “Taiwan” as “China,” Eric Huang (黃鈞耀), head of the Ministry of Foreign Affairs’ Department of European Affairs, told a news conference in Taipei yesterday. Reporters asked Huang whether the Danish government had responded to the ministry’s request that it correct the nationality on Danish residence permits of Taiwanese, which has been listed as “China” since 2024. Taiwan’s representative office in Denmark continues to communicate with the Danish government, and the ministry has revoked some privileges previously granted to Danish representatives in Taiwan and would continue to review
The first bluefin tuna of the season, brought to shore in Pingtung County and weighing 190kg, was yesterday auctioned for NT$10,600 (US$333.5) per kilogram, setting a record high for the local market. The auction was held at the fish market in Donggang Fishing Harbor, where the Siaoliouciou Island-registered fishing vessel Fu Yu Ching No. 2 delivered the “Pingtung First Tuna” it had caught for bidding. Bidding was intense, and the tuna was ultimately jointly purchased by a local restaurant and a local company for NT$10,600 per kilogram — NT$300 ,more than last year — for a total of NT$2.014 million. The 67-year-old skipper
China has reserved offshore airspace over the Yellow Sea and East China Sea from March 27 to May 6, issuing alerts that are usually used to warn of military exercises, although no such exercises have been announced, the Wall Street Journal (WSJ) reported on Sunday. Reserving such a large area for 40 days without explanation is an “unusual step,” as military exercises normally only last a few days, the paper said. The alerts, known as notice to air missions (NOTAMs), “are intended to inform pilots and aviation authorities of temporary airspace hazards or restrictions,” the article said. The airspace reserved in the alert
