Recent media interest about new types of submarines being developed by the People’s Liberation Army Navy (PLAN) could provide important clues about China’s naval capabilities and intentions, a specialist on China said in a recent article.
“Whereas the development and deployment of the Chinese navy’s surface fleet have been prominently displayed in unprecedented scale in recent naval exercises both in the South and East China Sea, the expansion of China’s subsurface fleet appears to have been slowed in recent years,” Russell Hsiao, editor of the China Brief, a publication of the US-based Jamestown Foundation, wrote in the publication’s latest edition.
From 2007 until this year, he said, the total number of submarines deployed in the PLAN was steady, rising by a single vessel, to 63, Hsiao wrote.
While the scope of the PLAN’s development remained to be seen and would depend on tested capabilities rather than media photos and speculation, the increased incidence of reports on new submarines could nevertheless provided important clues about Beijing’s strategic outlook, he said.
“In this context, these reports raise interesting questions about what is known regarding the pace of investments that China has undertaken to increase stealth, missile capacity, survivability and the capability to project its submarine force both regionally and globally,” he wrote.
Early last month, a Hong Kong-based media ran a story based on a photo of a new conventionally powered attack submarine that had been circulating on the Web for several weeks. The SSK submarine was allegedly developed by state-owned China Shipbuilding Industry Corp, China’s largest shipbuilder, the report said.
The People’s Liberation Army (PLA) has yet to officially acknowledge reports that the new submarine has stealth capabilities.
“Chinese academic engineering literature cited by a prominent Western defense magazine supports the fact ‘that the PLA has also been researching fuel cell AIP engine technology — with the PLA having benefited via Chinese academics from several conferences with German fuel cell technology experts,” the report said, citing Jane’s Defense Weekly.
“The addition of an AIP system could allow a Chinese submarine to operate underwater for up to 30 days on battery power, and would make the Song and Yuan submarines inaudible to existing US surveillance networks-and US subs,” the report said.
Reports also claim that China would finish testing and deploy two additional Yuan-class submarines by the end of next year, Hsiao wrote, adding that if reports were true, it would confirm the belief, held by some experts, that the apparent slowdown in the PLAN’s expansion was only a transitory phase and that its submarine fleet appeared set to resume its upward trajectory.
These revelations coincide with the recent sighting of a new Type 093 Shang-class nuclear-powered attack submarine docked at a Chinese naval base in Sanya, on Hainan Island. A photograph obtained by Japan-based Kyodo News showed two nuclear-powered submarines docked at a quay on the base.
Hsiao wrote that the reports and images showcasing new submarines and deployments underscored Beijing’s growing assertiveness, which has also been accompanied by an increasing incidence of sorties and exercises in waters close to Taiwan, Japan and South Korea.
A debt dispute between a restaurant owner and a criminal ring might be behind a bizarre cockroach attack at the Taipei eatery on Monday night while it was hosting a police gathering, Taipei Police Commissioner Chen Jia-chang (陳嘉昌) said yesterday. Preliminary findings of a police investigation into the case at the G House Taipei suggest that the unusual incident might have been directed at the restaurant’s owner, who allegedly owes money to the Bamboo Union, Chen said. The suspects were Bamboo Union members and there was no evidence indicating that the cockroaches were targeted at the police officers at the restaurant, he
Taiwan’s armed forces should closely monitor China’s development of a new tanker aircraft, as it would significantly boost the Chinese air force’s capability to carry out long-range raids, a military expert said on Wednesday. Ou Si-fu (歐錫富), a research fellow at the Institute for National Defense and Security Research, said in an online article that China is developing a tanker variant of its Y-20 military transport aircraft, known as the Y-20U. The Y-20 has a maximum take-off weight of 220 tonnes and the tanker variant is expected to carry up to 60 tonnes of fuel, more than three times the maximum
QUARANTINE BLUNDER: The government should be responsible for a cluster infection at a hotel, as the cases have caused panic, DPP Legislator Chen Ming-wen said The Ministry of Transportation and Communications should make it mandatory for pilots and flight attendants, as well as their family members, to be vaccinated in view of a cluster of COVID-19 cases at the Novotel Taipei Taoyuan International Airport hotel, lawmakers said at a meeting of the legislature’s Transportation Committee yesterday. The cluster infection at the hotel had led to 28 confirmed COVID-19 cases as of Tuesday, including hotel workers, as well as China Airlines flight and cabin crew, and their family members. The Central Epidemic Command Center (CECC) yesterday tightened quarantine requirements for pilots and flight attendants, who must quarantine
TRAVELING WHILE CONTAGIOUS: The highest risk of infection is indoors, especially in settings where people take off their masks to eat and drink, an expert warned The Central Epidemic Command Center (CECC) yesterday posted a list of places visited by people who were recently diagnosed with COVID-19 while they were likely contagious, urging people who visited the sites at the same time to practice self-health management. Minister of Health and Welfare Chen Shih-chung (陳時中), who heads the center, said that confirmed case No. 1,129 — a woman in her 60s who works at Novotel Taipei Taoyuan International Airport, a designated quarantine facility, and tested positive on Friday — visited Chiayi between Friday last week and Monday. On the first day of her trip, she visited the Big Chiayi
