As Taiwan struggles to enhance its submarine fleet, China is rapidly improving its anti-submarine warfare program, a study from Stratfor Global Intelligence said.
Stratfor is a US geopolitical intelligence firm that provides strategic analysis and forecasting to organizations around the world.
The days of Beijing relying on naval mines and depth charges for defense are coming to an end, the study said.
According to Stratfor, China has added Gaoxin-6 anti-submarine airplanes to its North Sea fleet, ramped up production of anti-submarine corvettes and equipped surface vessels with advanced detection equipment in the form of active variable-depth sonar and passive towed array sonar.
Stratfor said that China is also adding acoustic decoys and providing surface vessels with homing torpedoes.
The study came as high-level officials from Taiwan and the US meet in Washington this week for annual top-secret defense and security talks, during which Taiwan’s appeal for US help with its indigenous diesel-electric submarine program is believed to be on the agenda.
“The Chinese have been conducting extensive surveys and mapping of operating areas such as the South China Sea and are building a network of underwater sensors to detect submarines across the South and East China seas,” Stratfor said.
“On top of this, the [Chinese] military is experimenting with unmanned underwater vehicles with anti-submarine warfare applications. Most important, Chinese sailors, aircrew and technicians are consistently training to improve their skills,” it added.
Stratfor said that despite these advances, China’s anti-submarine defenses are still not sufficiently advanced or capable.
“While China could adequately clash with weaker powers such as Vietnam or Taiwan, the navy lacks the means to operate in the deep waters of the open ocean. It could not counter US nuclear submarines or even sophisticated diesel-electric submarines such as Japan’s.”
The study said that South Korea, Japan, Malaysia and Vietnam are developing or fielding large numbers of advanced diesel-electric submarines, a number of which are air-independent propulsion models, able to remain submerged for longer periods.
“Taiwan, a principal focus of Chinese war planning, is determined to build up its submarine fleet. With these improvements China now must contend with multiple submarine threats in most potential conflicts, making anti-submarine capabilities crucial,” the study said.
The study said that anti-submarine warfare is complex — equal parts art and science.
“It will take China years, if not decades, to become highly proficient in the craft. Moreover, the skillset is highly perishable. US Navy personnel even attest to how anti-submarine capabilities wane while the military focuses on other missions,” it said.
AGING: While Japan has 22 submarines, Taiwan only operates four, two of which were commissioned by the US in 1945 and 1946, and transferred to Taiwan in 1973 Taiwan would need at least 12 submarines to reach modern fleet capabilities, CSBC Corp, Taiwan chairman Chen Cheng-hung (陳政宏) said in an interview broadcast on Friday, citing a US assessment. CSBC is testing the nation’s first indigenous defense submarine, the Hai Kun (海鯤, Narwhal), which is scheduled to be delivered to the navy next month or in July. The Hai Kun has completed torpedo-firing tests and is scheduled to undergo overnight sea trials, Chen said on an SET TV military affairs program. Taiwan would require at least 12 submarines to establish a modern submarine force after assessing the nation’s operational environment and defense
A white king snake that frightened passengers and caused a stir on a Taipei MRT train on Friday evening has been claimed by its owner, who would be fined, Taipei Rapid Transit Corp (TRTC) said yesterday. A person on Threads posted that he thought he was lucky to find an empty row of seats on Friday after boarding a train on the Bannan (Blue) Line, only to spot a white snake with black stripes after sitting down. Startled, he jumped up, he wrote, describing the encounter as “terrifying.” “Taipei’s rat control plan: Release snakes on the metro,” one person wrote in reply, referring
The coast guard today said that it had disrupted "illegal" operations by a Chinese research ship in waters close to the nation and driven it away, part of what Taipei sees a provocative pattern of China's stepped up maritime activities. The coast guard said that it on Thursday last week detected the Chinese ship Tongji (同濟號), which was commissioned only last year, 29 nautical miles (54km) southeast of the southern tip of Taiwan, although just outside restricted waters. The ship was observed lowering ropes into the water, suspected to be the deployment of scientific instruments for "illegal" survey operations, and the coast
An inauguration ceremony was held yesterday for the Danjiang Bridge, the world’s longest single-mast asymmetric cable-stayed bridge, ahead of its official opening to traffic on Tuesday, marking a major milestone after nearly three decades of planning and construction. At the ceremony in New Taipei City attended by President William Lai (賴清德), Premier Cho Jung-tai (卓榮泰), Minister of Transportation and Communications Chen Shih-kai (陳世凱) and New Taipei City Mayor Hou Yu-ih (侯友宜), the bridge was hailed as both an engineering landmark and a long-awaited regional transport link connecting Tamsui (淡水) and Bali (八里)
