THE GLOBAL COVERAGE REGISTER / Underwater
Country-by-country coverage of air, land, sea surface and underwater systems, with an open research register.
The library covers aircraft, ground vehicles, surface vessels, underwater vehicles, selected variants, prototypes and reported concepts. Adjacent counter-UAS equipment is classified separately as support systems. Joint programmes count towards each named origin or production country; an importing country is not automatically a manufacturing country.
Totals describe published profiles, not fleet size or national completeness. Earlier regional audits focus on air systems; new domain audits identify separate land and maritime research needs. A country represented in the air catalogue may still have no ground or marine profile. Countries absent below have not been assessed in the selected scope.
