FCC Slams the Brakes on Foreign-Controlled Undersea Cable Projects Amid Rising Security Fears

A New Chapter in America’s Digital Security Strategy

The United States has tightened its grip on the deep-sea arteries of the internet, with the Federal Communications Commission (FCC) rolling out sweeping new rules aimed squarely at foreign-controlled companies. These undersea cables are the invisible lifelines of global communications, carrying more than 95% of the world’s international data. Now, amid escalating geopolitical tensions and mounting cybersecurity threats, Washington is making it much harder for certain foreign firms to gain access to U.S.-controlled waters for cable construction or operation.

The FCC’s Bold Security Overhaul

The FCC’s decision introduces a series of measures that could reshape the future of global telecom infrastructure. Foreign adversary-controlled license applicants will now face presumptive denials, effectively blocking them from operating critical submarine cable networks in U.S. territory. Leasing agreements for undersea cable capacity will also face restrictions, while the use of “covered equipment” deemed a security risk will be banned outright. Furthermore, foreign operators will need to meet new physical and cybersecurity compliance benchmarks to be considered for licensing.

The driving force behind these moves is the growing realization that control over undersea cables is not just about internet speed or connectivity — it’s about national security, economic dominance, and even artificial intelligence leadership. As FCC Chair Brendan Carr stated, America’s ambition to be the global leader in emerging technologies requires a rock-solid foundation, starting with secure and sabotage-proof data routes.

Currently, 90 cable systems are licensed in the U.S., but the FCC expects that number to soar as global connectivity demands increase. This is both an opportunity and a security dilemma. On one hand, the U.S. wants rapid infrastructure expansion. On the other, it fears that foreign-controlled firms could act as Trojan horses for espionage, cyberattacks, or even deliberate disruptions.

The risks are far from hypothetical. Intelligence reports and private assessments, like those from Recorded Future’s Insikt Group, highlight that while accidental damage (often from ships’ anchors or fishing activity) remains the most common cause of cable outages, targeted threats are on the rise. These include deliberate cable cuts, anchor dragging, and advanced cyber intrusion attempts aimed at intercepting or corrupting global data flows.

FCC Commissioner Anna Gomez pointed out that submarine cable regulations have not been updated in decades, despite the cables’ transformation into the backbone of the modern internet. The challenge now is to impose robust security measures without stalling economic growth or overburdening companies with red tape. As Gomez explained, the FCC’s task was to strike a balance: protect the infrastructure from foreign threats while streamlining the process to encourage investment.

With global competition for technological supremacy intensifying, the FCC’s move is both a defensive shield and an economic strategy. Whether this shift accelerates the U.S.’s push for digital dominance or creates friction with key global partners remains to be seen.

What Undercode Say:

The FCC’s clampdown on foreign-controlled undersea cable projects is not an isolated policy decision — it’s part of a broader U.S. playbook to secure the digital backbone against adversarial control. At the heart of this policy is the recognition that undersea cables are not just passive infrastructure; they are strategic assets as critical as oil pipelines or power grids.

From a geopolitical lens, this move signals Washington’s escalating wariness of China and other nations seen as potential threats to its technological dominance. Submarine cables don’t just transmit data — they carry military communications, financial transactions, and vast volumes of sensitive corporate information. Whoever controls or can compromise these cables holds enormous leverage in the modern information age.

The FCC’s measures are strategically aligned with other recent U.S. actions, such as banning Huawei equipment, tightening export controls on advanced semiconductors, and forging international agreements on digital infrastructure security. The new licensing rules extend this approach into the ocean floor — a domain that has, until recently, been an overlooked battlefield.

Critically, the rules acknowledge that the threat landscape has evolved. Cyberattacks now aim to exploit vulnerabilities at cable landing stations, while physical sabotage methods like anchor dragging have proven effective in disrupting service. By mandating both physical and cybersecurity measures, the FCC is covering both fronts.

Economically, the U.S. stands to benefit by promoting domestic and allied-led cable projects. This could attract billions in investment and create jobs, while reinforcing trust in the security of U.S.-linked data routes. However, there’s a trade-off: cutting out foreign adversaries might limit competition and potentially raise costs for global internet expansion.

For allies, this move may be welcome, as it aligns with broader efforts to secure Western-led infrastructure. For rivals, it could be perceived as an aggressive economic and technological containment strategy. Either way, it reinforces the reality that control of digital infrastructure is now a central arena of global power competition.

The FCC’s approach also addresses an often-overlooked fact — undersea cables are highly vulnerable points in global communication networks. Unlike satellites, they can be physically accessed and damaged relatively easily, and their repair is slow and costly. In a conflict scenario, targeting these cables could cripple a nation’s economy and intelligence-gathering capacity.

In the coming years, the effectiveness of these rules will depend on how well the FCC can enforce them without hindering the rapid expansion of internet capacity. The U.S. needs more cables, but it also needs them to be secure — a balancing act that will require constant recalibration as threats evolve.

Ultimately, this is not just a telecom story. It’s a strategic realignment of how the U.S. views and safeguards its digital arteries, and it signals to the world that the deep ocean floor is now officially a frontline in the global tech rivalry.

🔍 Fact Checker Results:

✅ The FCC has officially adopted new rules targeting foreign adversary-controlled submarine cable projects.
✅ Security concerns over China and other foreign actors are explicitly cited by FCC officials.
✅ Reports confirm that both physical sabotage and cyber threats to undersea cables are rising.

📊 Prediction:

Over the next five years, expect the U.S. to form multinational agreements with allies to build secure, jointly operated undersea cables. This will likely lead to a bifurcation of the global internet’s physical infrastructure — with one network dominated by the U.S. and its allies, and another shaped by China and its partners. This fragmentation could increase security but may also deepen geopolitical divides in the digital world.
