USTDA and National Telecom Partnership

On September 14, 2026, the U.S. Trade and Development Agency (USTDA) and Thailand's state-owned National Telecom Public Company Limited (NT) formalized a grant agreement to support feasibility research for the Thailand-U.S. Submarine Cable System (THUS). The agreement was signed at a ceremony led by Thailand's Minister of Digital Economy and Society Chaiyanok Chidchob, NT Chief Executive Officer Colonel Sanpachai Huvanandana, and USTDA Deputy Director Thomas R. Hardy. The project represents a major step toward establishing a high-capacity optical connection across the Pacific Ocean.

System Design and Route Strategy

The THUS infrastructure will extend approximately 11,500 miles (18,500 kilometers), linking Thailand directly to the United States with intermediate connection points in Indonesia, Malaysia, the Philippines, Singapore, and Vietnam. The cable's path deliberately avoids the South China Sea and other contested maritime zones, reducing exposure to cable damage and circumventing regulatory complications in politically sensitive areas.

Feasibility Study and Technical Oversight

National Telecom engaged APTelecom LLC, a Florida-based consulting firm, to lead the comprehensive feasibility assessment. The study will address commercial viability, engineering requirements, environmental considerations, and regulatory pathways across all jurisdictions involved in the project.

Market Scope and Operational Model

THUS will operate under an open-access framework, making high-capacity international bandwidth available to a regional market encompassing more than 600 million people. The system is designed to serve Thailand's hyperscale data centers, cloud infrastructure zones, and artificial intelligence facilities with direct connectivity to North America.

USTDA's Subsea Cable Strategy

USTDA's support for THUS operates within broader policy frameworks including the Partnership for Global Infrastructure and Investment (PGII) and the Digital Connectivity and Cybersecurity Partnership (DCCP). The agency uses grant funding to reduce financial and technical risk in submarine cable development across strategic regions.

  • Early-stage de-risking through technical due diligence, oceanographic analysis, and financial modeling to establish bankability
  • Enforcement of open-access principles and trusted supplier standards to safeguard critical infrastructure against cyber threats
  • Promotion of route diversity that avoids congested or politically sensitive deep-water passages

APTelecom's Role Across Multiple Projects

APTelecom serves as the primary technical advisor on multiple USTDA-backed submarine cable initiatives. The firm's responsibilities span marine engineering assessment, environmental and logistical evaluation of landing stations, commercialization strategy including capacity pricing and anchor-tenant arrangements, and multi-jurisdictional regulatory navigation.

Broader Indo-Pacific Cable Ecosystem

Beyond THUS, USTDA-supported submarine cable projects are reshaping connectivity across South and Southeast Asia. A cable connecting Chennai to Singapore, designed by SubConnex and APTelecom, addresses growing artificial intelligence workload demands and provides redundant routing across the Bay of Bengal and Malacca Strait. Within Indonesia, APTelecom's feasibility work for Super Sistem's 4,700-kilometer domestic backbone links the archipelago's major islands—Batam, Jakarta, and Manado—into international networks via Singapore. Vietnam's MViSTA system, developed by Stavian Group and OMS Group under USTDA cybersecurity guidelines, routes along Southeast Asian coastlines as a secure alternative to South China Sea deep-water paths.

USTDA's grant-funded approach, anchored by APTelecom's technical evaluation, is catalyzing trusted submarine cable expansion throughout the Indo-Pacific region. These investments establish open-access, cybersecurity-hardened, and geographically diverse fiber infrastructure to support the region's cloud computing and artificial intelligence development.
