Lloyd's Register

DeepFlight submarines are designed, built and tested to the highest standards. With safety as our number one priority, DeepFlight submarines are certified by Lloyd’s Register, a leading marine classification society.

Fixed Positive Buoyancy

DeepFlight submarines are designed with fixed positive buoyancy, meaning they automatically float to the surface if forward thrust is shut off.  Unlike all conventional submarines that incorporate variable thrust systems for ascent/descent, DeepFlight submarines dive purely on the power of thrust and downward lift on the wings.

Emergency Flotation System

All DeepFlight subs come equipped with an emergency gasbag system, which is completely mechanically operated and independent from the rest of the sub. In case of emergency, inflating the gasbags will turn the sub into a giant yellow life raft. You can then open the hatch and climb out on the surface.

Redundant Life Support

DeepFlight submarines come equipped with two independent oxygen supplies and two separate carbon dioxide filtration units, providing redundant safety for up to 72 hours of continuous operation. DeepFlight submarines feature easy to read digital instrumentation in the cockpit, making management of life support straightforward and user-friendly.

Communications and Tracking

Integrated underwater, surface and internal communications with backup VHF radios, enable smooth communications between the submarine and surface crew, and also between the cockpits.  DeepFlight submarines also have a USBL integrated tracking system for surface crew to continuously monitor the location of the submarine with a backup pinger locator beacon.
