The Republic of China (ROC) Navy has put a stop to trial runs of the new missile-carrying Tuo Jiang-class 618 stealth corvette due to serious design flaws that have undermined the vessel’s operations, senior navy commander Lu Li-shih (呂禮詩) told the Liberty Times (the Taipei Times’ sister newspaper) on Wednesday.
Lu said that several fundamentals flaws in the corvette’s design, along with it being packed with extra weapons and equipment systems, resulted in the vessel having insufficient buoyancy, which affected its maneuverability and stability.
Lu is a former captain of a Jin Jiang-class patrol vessel, which are similar to the 618.
“The core design concept was to build a stealth fast-attack corvette with high maneuverability,” Lu said. “However, later on the design was altered in a bid to make the Tuo Jiang-class ‘invincible warships,’ loading it with anti-aircraft and anti-ship weaponry, along with submarine-hunting and other combat functions.”
“It was like changing the design for a dress while a lady was already wearing it,” he said.
In addition to 16 Hsiung Feng-class missiles and two torpedo launchers onboard, the navy reportedly also has plans for the 618 to carry Sky Sword 2 guided missiles.
However, even without being fully loaded with fuel, equipment and weapons systems, the vessel had already reached its maximum displacement in calm water conditions in the harbor, Lu said.
“It is vital to have a patrol warship that can carry out missions in strong winds and high seas that can arise around Taiwan,” the commander said. “We must ensure the safety of all officers and sailors aboard the ship; that is the most serious challenge.”
Meanwhile, the Navy Command Headquarters said in a statement that the 618 is the first of its class and as a “prototype,” it was being tested to determine its capabilities and limitations.
“The Tuo Jiang class is a different design from traditional warships,” the statement said. “It is designed to be able to counter various threats using modular weapons systems, therefore its payload can vary depending on the situation.”
“Therefore the views are due to a misunderstanding regarding the vessel’s design concept and its operational objectives,” it said.
As the 618 is a prototype, handed over to the navy in December last year, the purpose of testing is to check the corvette’s performance and its limitations, while testing operational variables and deviations from its original design, the statement said.
Any issues that arise can then be corrected and plans reconfigured for subsequent production of more Tuo Jiang-class vessels, it added.
An essay competition jointly organized by a local writing society and a publisher affiliated with the Chinese Communist Party (CCP) might have contravened the Act Governing Relations Between the People of the Taiwan Area and the Mainland Area (臺灣地區與大陸地區人民關係條例), the Mainland Affairs Council (MAC) said on Thursday. “In this case, the partner organization is clearly an agency under the CCP’s Fujian Provincial Committee,” MAC Deputy Minister and spokesperson Liang Wen-chieh (梁文傑) said at a news briefing in Taipei. “It also involves bringing Taiwanese students to China with all-expenses-paid arrangements to attend award ceremonies and camps,” Liang said. Those two “characteristics” are typically sufficient
A magnitude 5.9 earthquake that struck about 33km off the coast of Hualien City was the "main shock" in a series of quakes in the area, with aftershocks expected over the next three days, the Central Weather Administration (CWA) said yesterday. Prior to the magnitude 5.9 quake shaking most of Taiwan at 6:53pm yesterday, six other earthquakes stronger than a magnitude of 4, starting with a magnitude 5.5 quake at 6:09pm, occurred in the area. CWA Seismological Center Director Wu Chien-fu (吳健富) confirmed that the quakes were all part of the same series and that the magnitude 5.5 temblor was
The brilliant blue waters, thick foliage and bucolic atmosphere on this seemingly idyllic archipelago deep in the Pacific Ocean belie the key role it now plays in a titanic geopolitical struggle. Palau is again on the front line as China, and the US and its allies prepare their forces in an intensifying contest for control over the Asia-Pacific region. The democratic nation of just 17,000 people hosts US-controlled airstrips and soon-to-be-completed radar installations that the US military describes as “critical” to monitoring vast swathes of water and airspace. It is also a key piece of the second island chain, a string of
The Central Weather Administration has issued a heat alert for southeastern Taiwan, warning of temperatures as high as 36°C today, while alerting some coastal areas of strong winds later in the day. Kaohsiung’s Neimen District (內門) and Pingtung County’s Neipu Township (內埔) are under an orange heat alert, which warns of temperatures as high as 36°C for three consecutive days, the CWA said, citing southwest winds. The heat would also extend to Tainan’s Nansi (楠西) and Yujing (玉井) districts, as well as Pingtung’s Gaoshu (高樹), Yanpu (鹽埔) and Majia (瑪家) townships, it said, forecasting highs of up to 36°C in those areas
