The Cousteau-class is a Starfleet submarine actively serving aboard Federation starships and installations during the latter half of the twenty-fourth century.
Cousteau-class submarines are direct descendants from the Cousteau-class starship project, abandoned at the outset of the Dominion War, with the hopes of providing a starship also suited for underwater operations. The Cousteau-class, however, has eschewed all atmospheric ability in favor of being quiet, efficient, and well adapted for the task of underwater exploration.
They are essentially run of the mill shuttlecraft based on the Delta Flyer-class design, with their nacelles converted from propulsion to sensor bundles, and a large turboprop in the aft providing propulsion. This system allows the craft to move virtually silently through the water, minimizing disruption to the ecosystems that it aims to study.
