Cold Bay, AK: Submarine Cable Landing Point

Cold Bay is a city located in the Aleutians East Borough of Alaska, United States, positioned along the Alaska Peninsula in the northern Pacific region. As a submarine cable landing point, Cold Bay hosts one submarine cable, connecting it to the broader subsea network infrastructure of the United States. Its location along the Aleutian chain situates it within a corridor that links different parts of the United States domestic network across the northern Pacific.

The single cable landing at Cold Bay is the AU-Aleutian system, a domestic United States route that runs along the Aleutian archipelago. This cable enables connectivity within the United States, supporting communications along one of the more geographically remote stretches of American coastline. Cold Bay's role as a landing point reflects the broader effort to extend submarine cable infrastructure to isolated communities along the Aleutian chain.

Cables Landing at Cold Bay, AK

The AU-Aleutian cable is the sole submarine cable landing at Cold Bay. Spanning 1,491 km in length and with a ready-for-service (RFS) year of 2022 (draft status), this system connects endpoints entirely within the United States, running along the Aleutian chain. Its relatively modest length compared to intercontinental cables reflects its function as a domestic intra-national route rather than a transoceanic link.

Regional Context

Within the United States, Cold Bay ranks among the more lightly served landing points. The country hosts 113 submarine cables across 160 landing points, and Cold Bay's single cable places it in the top 69% of United States landing points by cable count. By comparison, high-traffic hubs such as Boca Raton, FL and San Juan, PR each serve eight cables, while Hermosa Beach, CA, Kapolei, HI, and Myrtle Beach, SC each host five. Cold Bay's profile is more specialized, reflecting its remote geographic position rather than a role as a major convergence point.

Network Role

Cold Bay functions as a single-cable terminus rather than a multi-cable hub. The AU-Aleutian system it hosts is a domestic United States route, meaning Cold Bay's connectivity role is focused on extending network reach along the Aleutian Peninsula rather than bridging international or intercontinental routes. This distinguishes it from United States landing points that serve as nodes within global cable networks.

In the broader submarine cable graph of the United States, Cold Bay represents the type of landing point that prioritizes geographic reach into underserved or remote regions. Its presence in the network ensures that the Aleutian corridor has at least one point of subsea cable access, contributing to the overall coverage of the United States domestic submarine cable footprint.
