DeepFlight Submersibles: Pushing Deep-Ocean Exploration

Operational Depths Achieved

• DeepFlight I: 4,000 m (13,123 ft)
• DeepFlight II: 4,000 m (13,123 ft)
• DeepFlight III: 4,500 m (14,764 ft) — reached 4,481 m in Puerto Rico Trench (June 9, 2009).

Designed by Graham Hawkes and operated by the California Academy of Sciences, these uncrewed robotic subs enable scientific research at abyssal depths. Future engineering advances may allow even deeper dives.
