What the record for the farthest depth a submarine have gone?

The record for the deepest dive by a manned submarine is held by the DSV Limiting Factor, which reached a depth of approximately 10,928 meters (35,856 feet) in the Mariana Trench during its 2019 expedition. This achievement surpassed previous records set by the Trieste in 1960 and the Challenger Deep dive by James Cameron in 2012. The Limiting Factor is designed for repeated deep-sea exploration, demonstrating advanced engineering and resilience in extreme underwater conditions.
