Its first domestically developed submarine recently completed its maiden undersea trial, a major step for a project that Taiwan hopes will strengthen its security at sea (<a href=\"https:\/\/www.reuters.com\/business\/aerospace-defense\/taiwan-completes-first-undersea-trial-domestically-made-submarine-2026-01-30\/\">Reuters<\/a>). For many people in Taiwan, this was more than just a technical test. It was a sign that the island is trying to build more of its own military strength at a time of growing pressure from China.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">What Happened During the Test<\/h3>\n\n\n\n<p>According to Reuters, the submarine completed a <strong>shallow-water submerged navigation test<\/strong> off the southern port city of <strong>Kaohsiung<\/strong> (<a href=\"https:\/\/www.reuters.com\/business\/aerospace-defense\/taiwan-completes-first-undersea-trial-domestically-made-submarine-2026-01-30\/\">Reuters<\/a>). The submarine is called the <strong>Narwhal<\/strong>, also known in Chinese as <strong>Hai Kun<\/strong>. Taiwan\u2019s shipbuilder, <strong>CSBC Corp.<\/strong>, said the test showed progress in the long-running Indigenous Defense Submarine program. Focus Taiwan later reported that official video footage showed underwater navigation, steering and control system tests, and the raising and lowering of the periscope and antenna masts (<a href=\"https:\/\/focustaiwan.tw\/politics\/202602080004\">Focus Taiwan<\/a>).<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Why This Taiwan Submarine Trial Matters<\/h3>\n\n\n\n<p>This <strong>Taiwan submarine trial<\/strong> matters because Taiwan faces almost daily military pressure from Beijing, which claims the island as its own territory (<a href=\"https:\/\/www.reuters.com\/business\/aerospace-defense\/taiwan-completes-first-undersea-trial-domestically-made-submarine-2026-01-30\/\">Reuters<\/a>). Taiwan\u2019s military is much smaller than China\u2019s, so its leaders have focused on what is often called <strong>asymmetric warfare<\/strong>\u2014using mobile, flexible systems such as submarines, drones, and truck-mounted missiles to make any attack much harder and more costly (<a href=\"https:\/\/www.reuters.com\/business\/aerospace-defense\/taiwan-completes-first-undersea-trial-domestically-made-submarine-2026-01-30\/\">Reuters<\/a>).<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">A Difficult and Expensive Project<\/h3>\n\n\n\n<p>This submarine program has not been easy. Reuters reported that the project has faced delays because of international constraints and pressure from China (<a href=\"https:\/\/www.reuters.com\/business\/aerospace-defense\/taiwan-completes-first-undersea-trial-domestically-made-submarine-2026-01-30\/\">Reuters<\/a>). The first submarine carries a price tag of <strong>T$49.36 billion<\/strong>, or about <strong>US$1.58 billion<\/strong>, and it uses a combat system from <strong>Lockheed Martin<\/strong> along with U.S.-made <strong>Mark 48 heavyweight torpedoes<\/strong> (<a href=\"https:\/\/www.reuters.com\/business\/aerospace-defense\/taiwan-completes-first-undersea-trial-domestically-made-submarine-2026-01-30\/\">Reuters<\/a>). Taiwan plans to build up to <strong>eight submarines<\/strong>, and it hopes to have at least <strong>two<\/strong> domestically developed submarines deployed by <strong>2027<\/strong> (<a href=\"https:\/\/www.reuters.com\/business\/aerospace-defense\/taiwan-completes-first-undersea-trial-domestically-made-submarine-2026-01-30\/\">Reuters<\/a>).<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">The Political Message Behind the Trial<\/h3>\n\n\n\n<p>The submarine is also part of a bigger political message. In his Lunar New Year message in February 2026, President <strong>Lai Ching-te<\/strong> said Taiwan would continue to strengthen national defense and public security, and the official video included footage of the submarine during its undersea trials (<a href=\"https:\/\/www.reuters.com\/world\/china\/taiwan-president-vows-strengthen-islands-defences-lunar-new-year-message-2026-02-15\/\">Reuters<\/a>). In other words, Taiwan wants both its own people and the outside world to see that it is serious about defending itself.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">More Than Just a Boat<\/h3>\n\n\n\n<p>This story is about more than one submarine. It is about confidence, local industry, and long-term strategy. The <strong>Taiwan submarine trial<\/strong> shows that Taiwan is slowly building the tools it believes it needs for deterrence. The project still faces challenges, delays, and political pressure, but this first successful underwater test was a meaningful step forward.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Vocabulary<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Milestone<\/strong> (noun) \u2013 an important stage in progress.<br><em>Example:<\/em> \u201cThe undersea test was a major milestone for Taiwan.\u201d<\/li>\n\n\n\n<li><strong>Domestically developed<\/strong> (adjective phrase) \u2013 designed and built within one country.<br><em>Example:<\/em> \u201cTaiwan wants more domestically developed defense systems.\u201d<\/li>\n\n\n\n<li><strong>Deterrence<\/strong> (noun) \u2013 the ability to discourage an attack or action.<br><em>Example:<\/em> \u201cTaiwan hopes the submarine will improve deterrence.\u201d<\/li>\n\n\n\n<li><strong>Submerged<\/strong> (adjective) \u2013 under the surface of the water.<br><em>Example:<\/em> \u201cThe vessel completed a submerged navigation test.\u201d<\/li>\n\n\n\n<li><strong>Asymmetric warfare<\/strong> (noun) \u2013 a strategy where a weaker side uses different methods to challenge a stronger side.<br><em>Example:<\/em> \u201cTaiwan is investing in asymmetric warfare tools.\u201d<\/li>\n\n\n\n<li><strong>Constraint<\/strong> (noun) \u2013 a limit or restriction.<br><em>Example:<\/em> \u201cThe project faced international constraints.\u201d<\/li>\n\n\n\n<li><strong>Pressure<\/strong> (noun) \u2013 strong political or military force or influence.<br><em>Example:<\/em> \u201cChina has increased pressure on Taiwan.\u201d<\/li>\n\n\n\n<li><strong>Deploy<\/strong> (verb) \u2013 to place equipment or forces in a position for use.<br><em>Example:<\/em> \u201cTaiwan hopes to deploy more submarines by 2027.\u201d<\/li>\n\n\n\n<li><strong>Prototype<\/strong> (noun) \u2013 the first model of something new.<br><em>Example:<\/em> \u201cHai Kun is the prototype in the submarine program.\u201d<\/li>\n\n\n\n<li><strong>Strategy<\/strong> (noun) \u2013 a careful plan to reach a goal.<br><em>Example:<\/em> \u201cThe submarine is part of Taiwan\u2019s broader defense strategy.\u201d<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Discussion Questions (About the Article)<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li>What exactly happened during Taiwan\u2019s first undersea submarine trial?<\/li>\n\n\n\n<li>Why is this submarine important for Taiwan\u2019s defense plans?<\/li>\n\n\n\n<li>What does asymmetric warfare mean in this story?<\/li>\n\n\n\n<li>Why has the project faced delays and difficulties?<\/li>\n\n\n\n<li>What political message does this submarine send?<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Discussion Questions (About the Topic)<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Should smaller countries invest more in domestic defense production?
