Assessment

Case for · why it matters

Small and medium UUVs such as HII's REMUS are already in naval service for mine countermeasures and survey, and navies are now funding long-range and extra-large vehicles for ISR and strike: Australia signed an A$1.7B five-year Ghost Shark contract in 2025. Startups pitch cheap, mass-produced vehicles that could make waterways such as the Taiwan Strait costly to cross.

Case against · the skeptic’s view

Large-UUV programs have a poor record: the Navy's Orca XLUUV ran 64% over its cost estimate and at least three years late. Startup range and energy-density claims are largely unverified by independent tests, and early contracts such as Albacore's Navy deal have no disclosed value.
