The $370 million to $620 million system would double as a seafloor sensor array.

The study weighs a minimum configuration serving three facility groups around King George Island and the northern Antarctic Peninsula against an optimal configuration with nine Antarctic landing points, an option that Reports 2 and 3 recommend. The nine-landing version would connect research bases run by Chile, Argentina, Brazil, the United States, and the United Kingdom, all fed from landings at Punta Arenas and Puerto Williams in southern Chile and routed across the Drake Passage. Reporting from The Maritime Executive puts the minimum build near $370 million and the optimal build at roughly $620 million.
The study lists four features that separate the project from a commercial cable: Drake Passage weather, ice scour at the Antarctic landings, installation methods uncommon in Antarctica, and a plan to embed SMART sensors that measure ocean-bottom temperature, pressure, and seismic acceleration for climate and tsunami monitoring.
Each Antarctic landing would get a dedicated fiber pair rated at 15 to 30 Tbit/s through space-division multiplexing, with each base free to pick its own transmission equipment. To clear ice scour to about 340 meters of depth, the design calls for horizontal directional drilling at the Antarctic landfalls and double-armored cable, with installation spread across three austral summers inside the December-to-January weather window.
