Hawkes Ocean Technologies

Hawkes Ocean Technologies is a marine engineering firm that specializes in consumer submarines, founded by Graham Hawkes. It is headquartered in San Francisco, US.
Hawkes Remotes.
Hawkes Remotes is a subsidiary that builds ROVs (remotely operated vehicles), unmanned robotic submarines.
DeepFlight.
Hawkes builds the DeepFlight range of submersibles, which uses hydrodynamic forces for diving, instead of ballast. The subs are all-electric. All or some of them have two pairs of wings like an airplane's, one pair front and the other pair rear, shorter than an airplane's and the other way up so they push the submarine down.
