USTDA funds Thailand-US cable study; routing is the politics

The US Trade and Development Agency said this week it will fund a feasibility study for a trans-Pacific submarine cable connecting Thailand to the United States, leaving National Telecom, the country's state-owned carrier, to weigh whether the 18,507-kilometer (11,500-mile) Thailand-US Submarine Cable System can be built; the study is the cheap part, and the landing negotiations plus an unnamed capacity buyer will decide whether it gets built. NT has selected Florida-based APTelecom LLC to conduct the study, and the announcement does not include full details of potential landing points or routes.

The routing is the policy. USTDA says THUS could reach the United States through as many as five other Southeast Asian countries — Indonesia, Malaysia, the Philippines, Singapore, and Vietnam — while avoiding the South China Sea and "other routes that carry security risks." A system that touches five additional jurisdictions before it reaches open ocean is a negotiated asset rather than a laid one: each of those countries is a landing negotiation, an approval, and a potential point of delay, and the sequence of those agreements will matter more to the schedule than the marine survey does.

What THUS would replace has a name and a birthday: the Asia-America Gateway, a consortium system led by AT&T, NT, Globe and others, dates to 2009 and is the only subsea cable linking Thailand to the United States. The aging descriptor is earned, since one system carries the entire bilateral route, and the funding model for studying its replacement is different in kind: AAG was a carrier consortium's project, while the upfront work on THUS is being underwritten by a US development agency on behalf of a state-owned telco, with a US consultancy conducting the study.

"This activity will help ensure that the critical infrastructure connecting Thailand to the United States is built using trusted technology, protecting sensitive data from exploitation while advancing Thailand's ambitions to become a regional digital hub," said Thomas R. Hardy, USTDA's deputy director. Support for secure subsea systems, he said, helps safeguard networks while opening "new opportunities for U.S. companies to compete in one of the world's fastest-growing digital markets."

Colonel Sanpachai Huvanandana, president of National Telecom Public Company Limited, described THUS as "a strategic investment in Thailand's digital future," pointing to the resilience and diversity of the country's international networks, the growth of its data center, cloud, and AI sectors, and connectivity for "a regional market of more than 600 million people." USTDA's support, he said, "comes at a pivotal moment," because funding the upfront feasibility work "accelerates THUS toward bankability" and opens the door to collaboration with American technology providers.

Bankability is NT's own word, and it is the one to hold onto. The grant funds the upfront work that, in Sanpachai's telling, brings the project to the point where lenders and investors can be approached. The announcement includes no cost estimate for the system, no named capacity buyer, and no fixed landing point, which suggests the commercial case is still entirely open.

As this publication has argued about announced energy projects, a milestone with no number attached is development risk; until an offtaker or a lender names a figure, a completion announcement is a financing event rather than proof of an asset. Subsea cables run the same logic in a different vocabulary, where the number that matters is contracted capacity. On this record, THUS has a length and a route through the candidate countries and nothing in the announcement that a lender could price.

The contrast with US telecom infrastructure capital this month is sharp: TDS walked away from a minority buyout of Array's tower portfolio and chose to resume buybacks, leaving Array's 4,456 towers majority-owned but unconsolidated, a decision that values near-term capital return over incremental ownership. NT is examining the opposite posture: a multi-jurisdiction construction program whose cost, customers, and final route all remain unstated. Both are bets about what the next decade of connectivity is worth, and they are not the same bet.

For USTDA, the grant carries its own arithmetic: feasibility work is the cheapest place to influence a cable program, and Hardy's line about opening opportunities for US companies says what the agency expects in return — route alignment and a place at the table for American suppliers before procurement starts. The "trusted technology" language in his statement reads as a vendor condition in waiting, and it will shape the shortlist long before the study reports.

Demand is the other half, and NT's case rests on Thailand's data center, cloud, and AI growth plus a regional market of more than 600 million people — an argument about a market that is expanding rather than a book of signed contracts, and the two are not interchangeable at the lending stage. The next artifacts that would move THUS toward an actual cable are the study's landing plan and a first capacity contract with a named buyer. USTDA's grant covers only the paper that precedes them.
