Submarine cable licensing moved into a new phase after the FCC adopted its Second Report and Order, FCC 26-42, on June 25, 2026, and released it on June 30, 2026. As of August 27, 2026, most provisions are scheduled to become effective on September 25, 2026, while certain amendatory sections remain delayed indefinitely, according to the U.S. Government Accountability Office review of the rule GAO review. For carriers, cloud providers, cable owners, and security teams, the practical issue is not simply faster paperwork. The order changes who is covered, what must be certified, and how national security risk is screened before a cable can connect to U.S. networks.

What Submarine Cable Licensing Changes

Submarine Cable Licensing Timing And Scope

The revised rules clarify the licensing requirement for cables connecting the continental United States with a foreign country, cables connecting U.S. states, territories, or islands with foreign countries, and cables that are partly laid beyond U.S. territorial waters even when both endpoints are within U.S. jurisdictions. That scope matters because subsea systems are no longer narrow telecom assets. They support cloud regions, content delivery, financial messaging, enterprise connectivity, and interconnection between national networks.

The revised submarine cable licensing framework is designed to reduce avoidable delay while keeping a screening function for ownership, equipment, and operational risk. Before these reforms, Executive Branch review of submarine cable applications averaged 367 days from 2016 to mid-2020. From July 2020 to November 2024, the average fell to about 237 days. The 2026 rule adds a new route for applicants that satisfy specified national security standards: they may be presumptively exempted from full Executive Branch referral.

Blanket Treatment For Some SLTE Operators

A central technical change is the treatment of Submarine Line Terminal Equipment, or SLTE. FCC 26-42 states that, for the first time, the FCC is licensing SLTE owner-operators. SLTE connects submarine cables to U.S. terrestrial networks and was identified in the order as one of the most vulnerable parts of the system FCC order. The rule grants blanket licenses to current and future SLTE owners and operators that are not already licensees and are not subject to foreign adversary disqualifying conditions.

That change brings a part of the cable system closer to direct regulatory oversight. It also reflects how risk concentrates at the interface between subsea transport and terrestrial routing, switching, monitoring, and management systems. A cable span can be physically secure, but weak terminal controls, poor vendor assurance, or unclear operational responsibility can still create exposure.

Security Duties Move Closer To The Equipment

Certification Is Not A Substitute For Controls

The order introduces certifications, routine reporting duties, and ten specified national security standards. These are not presented as optional best practices. They become part of the compliance path for applicants seeking faster treatment and for licensees subject to the new operating expectations.

One requirement is the development of cybersecurity and physical security risk-management plans under section 1.70006(c). The research record associated with the rule estimates one-time implementation costs of about $28.5 million for affected entities, with annual costs of about $10.7 million. Those numbers should be read as compliance-cost estimates, not as a guarantee that all implementation burdens will be evenly distributed. A large multinational cable operator with mature governance may face a different operational lift than a smaller entity that needs to formalize inventories, supplier screening, incident processes, and physical access controls.

Foreign Adversary Screening Adds A Governance Layer

The rule also creates presumptive disqualifications for entities owned by, controlled by, or subject to the jurisdiction or direction of a foreign adversary, as well as entities on the FCC’s Covered List. Those presumptions are not framed as automatic in every circumstance, but affected entities must overcome them through the character-showing process described in the rules.

SLTE owners and operators that fall under foreign adversary criteria must provide annual foreign adversary reports and operate under stricter oversight. Certifications also require attention to whether principal equipment and services originate from Covered List entities or foreign adversary jurisdictions. For procurement teams, this pushes cable security beyond route planning and landing-station protection. Vendor due diligence, ownership analysis, software provenance, and equipment lifecycle management become part of the connectivity risk file.

Connectivity Benefits Are Real But Conditional

Faster Review Can Reduce Deployment Friction

The connectivity case for the rule is straightforward: shorter licensing review can reduce one bottleneck in subsea cable deployment. Submarine systems carry an estimated 99% of intercontinental data traffic and support more than $10 trillion in global financial transactions per day. If licensing delay is reduced for applicants that meet the ten standards, capacity can reach service sooner than under a slower review path.

That benefit is especially relevant for AI workloads, cloud services, and digital platforms that require high-capacity international links. Analysts should be cautious, though, about treating the rule as a capacity guarantee. Permitting, marine surveys, cable manufacturing, landing-station construction, financing, route risk, geopolitics, and maintenance vessels remain separate constraints. The FCC can streamline a federal licensing process, but it does not remove every deployment dependency.

Security Requirements May Slow Weak Applications

The same rule that can accelerate well-prepared applications may expose gaps in weaker applications. An operator that cannot document security controls, ownership structure, supplier risk, and SLTE responsibility may not receive the same review benefit. In that sense, the order rewards operational readiness rather than speed alone.

For technology professionals, the change creates demand for practical competence in telecom security governance: asset inventories, third-party risk review, physical site control, incident reporting workflows, configuration management, and resilient operations. Teams that track adjacent infrastructure topics through resources such as those provided on techncoins.net, a related site in the same network should treat subsea cables as part of the broader stack supporting data-intensive services, not as isolated marine assets.

How Submarine Cable Licensing Changes Connectivity Risk

The rule changes the risk profile by tying faster treatment to a defined security baseline. That is a meaningful shift from a model where national security review could be lengthy and less predictable for applicants. A clearer standards-based pathway can make project planning more predictable, especially for sponsors able to meet the certification and reporting requirements early in the design cycle.

At the same time, the order raises the minimum operating standard. Licensees and covered SLTE operators must be prepared to show that their systems do not depend on prohibited or high-risk equipment and services where the rule bars them. They also need plans that address cyber and physical security in a coordinated way. This is not only a legal function. Network engineering, procurement, security operations, compliance, and executive governance all need consistent records and accountability.

Area	Practical Effect	Likely Team Impact
Application review	Qualified applicants may avoid full Executive Branch referral	Legal, regulatory, project finance
SLTE oversight	SLTE owner-operators are brought into licensing coverage	Network engineering, landing-station operations
Security plans	Cybersecurity and physical security plans are required	Security, facilities, operations
Foreign adversary rules	Covered entities face presumptive disqualification or tighter reporting	Governance, procurement, compliance
Cost profile	Implementation and annual compliance costs become part of project economics	Finance, program management

The table shows why the order should not be read as deregulation in a simple sense. It removes some procedural friction for applicants that can satisfy the standards, while adding clearer duties for security, reporting, and equipment assurance. That tradeoff is consistent with the dual pressure facing global connectivity: networks need more capacity, but the infrastructure is exposed to state-linked risk, supplier concentration, and physical disruption.

Submarine Cable Licensing Signals For Operators

For operators and infrastructure professionals, the near-term work is specific. Project teams should map whether a planned or existing cable falls within the clarified license scope. They should identify all SLTE owners and operators, confirm whether blanket treatment applies, and document whether any party creates a foreign adversary or Covered List issue. Waiting until late in the application process is likely to create avoidable friction.

• Build security and physical protection plans early enough for review by engineering, legal, and operations teams.
• Track principal equipment and service providers against Covered List and foreign adversary restrictions.
• Assign ownership for SLTE compliance, reporting, and operational evidence.
• Keep cost estimates current for one-time implementation work and recurring compliance activity.
• Use the ten national security standards as a project checklist, not only as a filing attachment.

The FCC’s 2026 order is best understood as a shift toward conditional acceleration. Stronger applicants may see a faster path to approval, while weaker governance may face closer scrutiny. For global connectivity, that balance is consequential. Subsea cable capacity remains essential to intercontinental data movement, but capacity without verifiable security controls is a fragile asset. The rule does not solve every deployment or geopolitical problem, but it gives operators a clearer framework for proving that new and existing cable systems can connect to U.S. networks with documented accountability.
