Fighting for the Seafloor: From Lawfare to Warfare

Seabed Warfare Week

By LTJG Kyle Cregge

As the United States Navy looks to space and cyber as new domains for warfare, it also ought to look deeper: to the seafloor. Increased competition for vital resources and the intent to control critical sea lines of communication will drive nations and their navies to the seabed. There are three serious operational challenges ahead for the U.S. Navy that will require both technical and intellectual investment to properly establish security on the seafloor.

In the context of seabed warfare the three challenges align with the first three operational phases of war as part of U.S. doctrine: 0, Shape the Environment; 1, Deter Aggression; and 2, Seize the Initiative. In Phase 0, the U.S. will have to grapple with the difficulty of shaping an environment governed by an international legal structure which the U.S. is not party to. In Phase 1, the U.S. will be challenged to deter potential seabed exploitation by submarines and unmanned or automated underwater vehicles (UUVs or AUVs) in the vast depths of the oceans. Such platforms will be limited in their communication with other vehicles or fleet command centers due to their distributed use and the inability to communicate quickly, reliably, and secretly at great water depths. When the Navy is required to seize the initiative in Phase 2, open warfare, the seabed will serve to expand the enemy threat area beyond the first thousand meters of the water column thereby increasing risk for forces enter....
