CIMSEC – Every strategy is ultimately shaped by geography, and no geography in the Indo-Pacific is more decisive than Taiwan’s location between the Strait and the Pacific. For decades, Taiwan, its partners, and even its adversaries have assumed that the island’s fate will be decided westward, across the Taiwan Strait. But the Strait is no longer a protective moat; it is a narrowing corridor easily sealed by missiles, naval patrols, and even insurance premiums. The waters that once carried Taiwan to prosperity now form the most vulnerable seam in its defenses. Taiwan’s endurance depends on building resilience at home and reorienting its future growth eastward.

Naval News – STR8 Industries has developed Ghostwake, an unmanned surface vessel that the firm designed for operations across the first island chain and production through Taiwan’s industrial base. 

USNI News – Taiwanese forces mobilized mechanized units, engineering troops and mines across a river estuary crucial for the defense of the island’s capital city during the opening days of Han Kuang 42. Among the paths for a potential Chinese invasion of the island’s capital, the approach from the Tamsui River will be critical for both attacker and defender.

CIMSEC – Operation Spiderweb should haunt Taiwan’s strategic imagination. It demonstrated that cheap, expendable drones can neutralize assets once considered untouchable. For Taipei, the message is urgent: the future battlespace will be saturated by unmanned systems, and deterrence will depend on numbers, resilience, and adaptability. But ambition without follow-through is a liability. Taiwan must move from speeches and declarations toward mass production, component autonomy, doctrinal change, and tightly integrated partnerships, especially with the United States and with Ukraine.

USNI News – Taiwan’s newly acquired American attack drones struck maritime targets for the first time last week along the island’s west coast during live-fire drills designed to validate long-range strike systems that would play a crucial role in a potential invasion of the self-governing island.

Modern War Institute – Discussions regarding the defense of Taiwan increasingly feature the idea that low-cost emerging technologies are an answer to China’s geopolitical position and overwhelming military might. 

Naval News – According to media reports in Taiwan, the Republic of China (ROC) Navy is reportedly considering Japan’s New FFM (also known as Upgraded Mogami-class or 06FFM) design as a possible frigate candidate.

War on the Rocks – The Hellscape concept shifts the strategic calculus. The question is no longer whether Taiwan can win a conventional war against China. The question is whether Beijing can stomach the operational chaos, staggering casualties, and strategic uncertainty that an invasion would bring. By making an assault prohibitively costly and dangerously unpredictable, Taiwan can deter it from happening in the first place.

USNI News – Taiwan received the first batch of an advanced drone order from the U.S. last week that is set to bolster Taipei’s over-the-horizon targeting capabilities.

Breaking Defense – Taiwan’s current approach to defense is unlikely to deter Chinese aggression, and it needs a new operational concept that builds mass and provides operational flexibility but yet remain affordable, according to a new report.

Australian Strategic Policy Institute – Bill Sweetman writes that Ukraine’s massive drone strike against Russian air bases on 1 June should reverberate across all theaters of conflict. But there is one Western Pacific scenario where it could be very relevant indeed: a Chinese invasion of Taiwan.

Defence Blog – Taiwan’s domestically built Hai Kun submarine experienced a serious hydraulic system failure during sea trials, temporarily leaving the vessel without powered control of its X-shaped stern rudder and forcing sailors to rely on manual steering to avoid an accident, according to an exclusive report by Mirror Media.

Global Times – The island of Taiwan’s “indigenous” submarine Hai Kun, which the armed forces on the island had confidently claimed would be delivered in November, has not only failed to complete basic underwater navigation tests but has recently been reported to have problems such as “uninstalled anchors” and “unintegrated watertight door systems.” This has drawn sharp criticism within the island for “endangering crew members’ lives.”

It could also be employed against targets on land and act as a decoy.
