Larsen Bay, AK: Submarine Cable Landing Point

Larsen Bay is a small city located in Kodiak Island Borough, Alaska, United States. Situated on Kodiak Island in the Gulf of Alaska, it serves as a submarine cable landing point on the western edge of the United States telecommunications network. One submarine cable lands at Larsen Bay, connecting it to the broader domestic cable infrastructure of the country.

The single cable serving Larsen Bay is the AU-Aleutian system, a domestic route that links points within the United States. This cable supports intra-national connectivity along a corridor that extends through the Aleutian region of Alaska, a geographically remote stretch of coastline where terrestrial infrastructure alternatives are limited. The landing at Larsen Bay represents a notable northerly terminus within the United States submarine cable map.

Cables Landing at Larsen Bay

The AU-Aleutian cable is the sole submarine cable landing at Larsen Bay. Spanning 1,491 km in length and recorded with a ready-for-service (RFS) date of 2022 (draft status), the AU-Aleutian system connects landing points entirely within the United States. Its route serves communities along the Alaskan coast and Aleutian Island chain, providing domestic submarine connectivity across one of the most geographically challenging and remote maritime environments in the country.

Regional Context

Within the United States, which hosts 113 submarine cables across 160 landing points, Larsen Bay is among the more lightly served locations, hosting a single cable. By cable count, it ranks within the top 69% of the 167 United States landing points. Compared to high-density hubs such as Boca Raton, FL and San Juan, PR — each hosting eight cables — or Hermosa Beach, CA and Kapolei, HI with five cables each, Larsen Bay serves a distinctly specialized and localized connectivity function rather than acting as a convergence point for multiple international or regional routes.

Network Role

Larsen Bay functions as a single-cable terminus within the United States domestic submarine network. Its role is defined by the AU-Aleutian cable, which provides submarine connectivity between remote Alaskan communities that are otherwise difficult to reach through overland infrastructure. The cable's entirely domestic endpoint configuration means Larsen Bay does not participate in international submarine corridors, but instead supports intra-national reach into some of the most isolated populated areas of Alaska.

In the broader United States submarine cable graph, Larsen Bay represents the type of landing point that extends network access into geographically peripheral locations. Its presence as a cable landing point highlights how submarine systems serve not only intercontinental traffic but also essential domestic connectivity in remote island and coastal communities.
