Global Risks to Undersea Infrastructure and the Growing Need for Defense

All Hands on Deck by StrongerNavy.org

Undersea cables are the unseen arteries of modern communication, carrying 99% of the world’s internet and telecommunications traffic. Yet, as geopolitical tensions rise, these vital systems are becoming frequent targets of sabotage and hybrid warfare. Incidents from the Baltic Sea to the Taiwan Strait highlight both their strategic importance and vulnerabilities.

The Stakes: Why Undersea Cables Matter

  • Global Communication: These cables carry 99% of international data, enabling everything from financial transactions to government communications.
  • Economic Lifeline: Damaging these cables can disrupt trillions of dollars in daily transactions, impacting economies and businesses globally.
  • Military and Security Concerns: Undersea cables are vital for military communication, making them high-value targets in hybrid warfare strategies.

Recent Incidents and Their Implications
Baltic Sea

  • October 2023: The Hong Kong-registered containership Newnew Polar Bear dragged its anchor across the seabed, damaging the Balticconnector natural gas pipeline and data cables in the Gulf of Finland. The ship fled toward Russia, evading investigation.
  • December 2024: A power cable between Finland and Estonia was severed, and suspicion fell on a Russian “shadow fleet” tanker, the Eagle S. Finnish authorities found specialized surveillance equipment on board, allegedly used to monitor naval activity.

Taiwan Strait

  • February 2023: Two undersea cables connecting Taiwan to the Matsu Islands were severed by a Chinese fishing boat and cargo vessel, leaving the island without internet for weeks.
  • January 2025: The freighter Shunxin-39 severed a cable off Taiwan’s northern coast. Although the ship escaped investigation, Taiwan suspects deliberate sabotage. Herming Chiueh, Deputy Head of Taiwan’s Digital Ministry, said the cable-cutting was likely intentional: “You need to accidentally [drop your] anchor on the cable, and then you need to accidentally turn on your engine with the anchor down, and even [if] you realize your anchor is down, you need to keep the engine moving until you cut the cable.”

Red Sea

  • Houthi rebels were suspected of damaging cables belonging to four major telecom networks, though the group denied involvement.

The Strategic Significance of Undersea Infrastructure

  • Economic Importance: These cables carry trillions of dollars in financial transactions daily. Disruptions can cripple economies, hinder communication, and destabilize global markets.
  • Military Implications: Reliable undersea communications are vital for military operations and coordination. Sabotage could cripple responses during crises, delaying information flow and strategic decisions.
  • Geopolitical Pressures: Russia and China employ unorthodox tactics to assert dominance and destabilize their adversaries.

U.S. Navy and Allied Responses

  • Enhanced Patrols: NATO and allied nations are increasing naval presence in the Baltic and other regions to monitor suspicious activity.
  • Technological Investments: AI-driven systems and underwater sensors are being deployed to detect and deter sabotage.
  • Policy and Collaboration: Strengthened international legal frameworks and collaborative efforts among allies are essential for defending undersea infrastructure.

The Way Forward

  • Mitigating Risks: Building redundant systems, deploying advanced monitoring technologies, and fostering public-private partnerships are key steps to reduce vulnerabilities.
  • A Call for Action: Safeguarding undersea cables requires prioritization at the highest levels of government and international collaboration to counter hybrid threats.

Undersea cables, often taken for granted, are critical to the global economy, security, and military operations. The recent spate of incidents underscores the need for vigilance, innovation, and collaboration. For the U.S. and its allies, safeguarding these invisible lifelines is not just a technical challenge—it’s a strategic imperative.

Why Taiwan Matters for America and Its Navy

Taiwan – Wikipedia

Introduction

Taiwan is a small island nation off the coast of China, with a population of about 23 million people and a land area of about 14,000 square miles. It is also one of the most important and contentious issues in global security, especially for the United States and its Navy.

Taiwan’s History and Status

Taiwan has a complex and contested history with China, which claims Taiwan as part of its territory and vows to reunify with it by force if necessary. Taiwan, on the other hand, has developed its own identity and democracy, and seeks to maintain its autonomy and sovereignty. The United States has been Taiwan’s main ally and protector since 1979, when it established the Taiwan Relations Act, which commits the United States to provide Taiwan with arms sales and assistance, and to help Taiwan defend itself against any threats or attacks.

However, the United States has also maintained a policy of strategic ambiguity on Taiwan, which means that it neither promises nor rules out military intervention in case of a Chinese attack. This policy is intended to deter both China and Taiwan from taking any provocative or unilateral actions that could destabilize the status quo and trigger a war. However, this policy also creates uncertainty and confusion for both sides, as well as for the United States itself.

Taiwan as a Tipping Point

In his recent speech at the Global Security Forum ’23, Professor James Holmes, a professor of strategy at the Naval War College and a nonresident fellow at the University of Georgia School of Public and International Affairs, addressed the question of whether Taiwan will be a tipping point in global security. He defined a tipping point as a change of state that involves cause and effect and time. He used the metaphor of a boiling point to illustrate his definition, and he explained how human beings can regulate changes of state by adjusting the heat or pressure in a system.

He then applied his definition and metaphor to the case of Taiwan, which he considered to be a potential flashpoint between the United States and China. He argued that Taiwan is not yet at a tipping point, but it could be if certain conditions are met. He identified three conditions that could trigger a tipping point:

(1) China decides to use force to reunify with Taiwan;

(2) the United States decides to intervene militarily to defend Taiwan; and

(3) Taiwan decides to declare formal independence from China.

He analyzed each of these conditions and evaluated their likelihood and consequences. He concluded that none of them are very likely or desirable, but they are not impossible or unthinkable either. He warned that miscalculation, misperception, or miscommunication could lead to an escalation or a crisis that could push Taiwan over the tipping point. He also cautioned that domestic politics, public opinion, and media influence could affect the decision-making process of the actors involved.

How to Prevent or Manage Tipping Point

He then offered some recommendations on how to prevent or manage a tipping point in Taiwan. He suggested that the United States should maintain its strategic ambiguity on Taiwan, which means that it should neither promise nor rule out military intervention in case of a Chinese attack. He also advised that the United States should strengthen its deterrence and diplomacy vis-à-vis China, which means that it should bolster its military presence and capabilities in the region, as well as engage in dialogue and cooperation with China on areas of common interest. He also proposed that the United States should support Taiwan’s security and democracy, which means that it should provide arms sales and assistance to Taiwan, as well as encourage its participation in international organizations and forums.

Why Taiwan Matters For America’s Interests and Values

Why should Americans care about Taiwan? Because Taiwan matters for America’s interests and values, as well as for its Navy’s missions and objectives. Taiwan is an important economic partner and trading partner for the United States, with bilateral trade worth over $100 billion in 2020. Taiwan is also an important democratic ally and friend for the United States, sharing common ideals and principles such as freedom, human rights, and rule of law. Taiwan is also an important strategic partner and asset for the United States, helping to balance China’s power and influence in Asia-Pacific.

Why Taiwan Matters for America’s Navy

Taiwan is also crucial for America’s Navy, which has been operating in the western Pacific for over 70 years. The Navy’s role is to protect U.S. interests and allies in the region, as well as to ensure freedom of navigation and access to the global commons. The Navy’s presence is also meant to deter China from using force or coercion against its neighbors, especially Taiwan. The Navy’s capabilities are also essential for responding to any contingency or crisis involving Taiwan, whether it is humanitarian assistance or military intervention.

Taiwan is not only an island nation; it is also an idea worth defending. It represents what America stands for: democracy, liberty, and peace. It also represents what America needs: a strong Navy that can protect its interest and values around the world.
