Japan Considers Allowing U.S. Nuclear-Armed Warships to Dock, Revising Decades-Old Non-Nuclear Principles

Japan Considers Allowing U.S. Nuclear-Armed Warships to Dock, Revising Decades-Old Non-Nuclear Principles

Japan is contemplating an exception to its long-standing 'Three Non-Nuclear Principles' by potentially allowing U.S. military warships carrying nuclear weapons to enter Japanese ports during emergency situations. This move is part of revisions to Japan's three key national security documents, expected to be finalized by the end of 2026. The 'Three Non-Nuclear Principles,' articulated in 1967 and formally adopted in 1971, state that Japan will not possess, produce, or permit the introduction of nuclear weapons into its territory. While the first two principles are intended to remain, the Takaichi administration is considering explicitly stating exceptions to the 'no introduction' rule. This consideration stems from a belief that ensuring Japan's security, particularly under the U.S. nuclear umbrella, necessitates the temporary entry of U.S. ships with nuclear capabilities, especially given the increasingly harsh security environment in the Indo-Pacific region with nuclear-armed neighbors like China, Russia,...

U.S. Navy Develops Next-Generation SSN(X) Nuclear Attack Submarine with Drone Capabilities

The U.S. Navy is developing a new nuclear attack submarine, designated SSN(X), which is designed to be faster, require less maintenance, and function as a 'mothership' for undersea drones. Rear Adm. Andrew Miller, head of submarine requirements, announced these details on November 12, 2026, at the Naval Submarine League’s annual conference in Arlington, Virginia. The Navy is finalizing the program's analysis of alternatives (AoA) and aims for Milestone A approval, marking entry into early development, by the end of 2026. The SSN(X) is intended to succeed the Virginia-class submarines, with construction planned to begin in the early 2040s. Key characteristics include higher flank and tactical control speeds, improved operational availability, decisive lethality, superior stealth, layered survivability, and organic hosting and command and control of robotic and autonomous systems. The Navy's FY2026 budget requested $622.8 million for SSN(X) research and development, including funds for a new reactor plant.

Taiwan Expresses Concern Over Unannounced PLA Military Deployments Near Its Main Island

Taiwan Expresses Concern Over Unannounced PLA Military Deployments Near Its Main Island

Taiwan's defense ministry has reported continued unannounced military activity by China's People's Liberation Army (PLA) near its territory. Between Thursday and Friday morning, 30 Chinese warplanes were detected operating near Taiwan, with 23 of these aircraft approaching closer to Taiwan's main island. This surge in activity comes as China prepares to host world leaders at the APEC summit in Shenzhen next week. A U.S.-based think tank suggests that China may be attempting to normalize large, unannounced military deployments in the Taiwan Strait. Analysts are closely watching whether these operations will continue after the APEC summit, as sustained activity could indicate a long-term strategic focus on regional military deployments and planning by Beijing.

North Korea's Kim Jong-un Inspects Naval Base Construction, Emphasizing National Security

North Korea's Kim Jong-un Inspects Naval Base Construction, Emphasizing National Security

General Secretary Kim Jong-un recently inspected the construction of a significant naval base on North Korea's east coast, a project he described as crucial for national security and maritime sovereignty. This inspection follows a visit to the Nampo Shipyard on November 2, where photos revealed a hull believed to be a 10,000-ton cruiser that North Korea had previously announced plans to build. Additionally, on November 9, institutions including the Academy of National Defense Science conducted tests on a new torpedo weapon, slated for naval deployment in early 2027. These developments indicate a strategic shift towards enhancing naval power, following years of focus on developing missile capabilities for nuclear warheads. The specific location of the naval base was not disclosed, but it is likely the same site, Dapchon Port in Munchon, Gangwon Province, that Kim Jong-un inspected two years prior when he ordered its construction.

US Alliances in Northeast Asia Face Challenges Amidst Authoritarian Cooperation

US Alliances in Northeast Asia Face Challenges Amidst Authoritarian Cooperation

The United States maintains two strong bilateral alliances in Northeast Asia, with Japan and South Korea, designed to ensure regional power projection and deter North Korea. Recent initiatives, such as the 2023 Camp David Trilateral Summit, real-time missile warning data-sharing, and Freedom Edge exercises, have strengthened trilateral cooperation. However, defense planning in these democracies remains largely centered on geographically separated contingencies. This approach is problematic as China, Russia, and North Korea are increasingly linking security environments across different geographical areas. North Korea's support for Russia in the Russo-Ukrainian war, including troop dispatches and munition supplies, is enhancing Pyongyang's military capabilities and could shift the balance of power on the Korean Peninsula. China's economic relationship with Russia helps Moscow withstand Western pressure, and China-Russia military cooperation complicates US and Japanese defense planning. This growing strategi...

U.S. Navy Awards BAE Systems $137 Million Contract for Virginia-Class Submarine Propulsion Systems

U.S. Navy Awards BAE Systems $137 Million Contract for Virginia-Class Submarine Propulsion Systems

The U.S. Navy has awarded multinational defense giant BAE Systems a contract worth approximately $137.66 million to manufacture new pump-jet propulsor assemblies for its Virginia-class nuclear-powered attack submarines (SSNs). The Naval Surface Warfare Center Carderock Division is identified as the contracting organization. This contract covers production, engineering services, replacement parts, and associated support, with an ordering period extending through September 2032. Virginia-class submarines utilize pump-jets instead of conventional screw propellers, which are designed to be quieter and harder for adversaries to detect. These propulsors incorporate a rotor and stationary flow-conditioning components within a surrounding duct or shroud, managing water flow to reduce cavitation and improve acoustic performance. Precision manufacturing is critical for these components, as any imperfection can create vibrations and unwanted acoustic signatures that compromise detection advantages. BAE Systems, which...

U.S. Virginia-Class Submarine Colorado to Lead New Rotational Force in Australia Under AUKUS Agreement

U.S. Virginia-Class Submarine Colorado to Lead New Rotational Force in Australia Under AUKUS Agreement

The U.S. Virginia-class submarine Colorado is slated to become the inaugural submarine assigned to Submarine Rotational Force-West (SRF-West), commencing late next year. This initiative is a key component of the trilateral AUKUS agreement, established in 2021 between the United States, the United Kingdom, and Australia. Rear Adm. Chris Cavanaugh, commander of Submarine Forces for the U.S. Pacific Fleet, stated that the AUKUS agreement is on schedule and, in some aspects, even ahead of schedule. The USS Colorado recently completed a month-long maintenance period in Australia and will return next year to establish SRF-West at the Royal Australian Navy base HMAS Stirling. The reactivation of Submarine Squadron 3 in the spring is also in support of standing up SRF-West, which aims to provide a rotational presence of nuclear-powered fast-attack submarines from the U.S. (up to four) and the UK (one) at HMAS Stirling. This development is part of Pillar I of the AUKUS deal, which focuses on providing Australia wit...

China's Multilateral Policy Aims to Prevent Security Threats in East Asia

China's Multilateral Policy Aims to Prevent Security Threats in East Asia

China's multilateral policy is primarily focused on preventing security threats, particularly those arising from territorial disputes in the South China and East China Seas. For approximately two decades, China has employed a selective approach to multilateralism, choosing specific legal and regional forums for participation and establishing institutions under its leadership. This strategy also involves allowing soft-law agreements that provide strategic flexibility. The core of China's multilateralism in this context is to establish communication and crisis-management channels, shift contentious issues towards low-politics cooperation (such as joint development and environmental protection), influence norms and agenda-setting to reduce third-party intervention, and utilize economic multilateralism as a tool for restraint through incentives. This selective engagement, coupled with an openness to vague multilateral situations and a reluctance to engage in binding adjudication that might not favor its claims...
