Hyper Horizon builds small autonomous submarines that map the sea without a pilot

India has made steady progress above the waterline: satellites, drones, aircraft.

Below it, less.

Autonomous underwater vehicles, machines that can navigate, survey and map without a cable to the surface or a human at the controls, have largely been imported.

That price point shapes what gets done.

A single expensive vehicle is deployed carefully, for high-value work, by trained crews.
