How far can the deepest submarine?

The deepest submarine, the DSV Limiting Factor, can reach depths of around 10,928 meters (35,856 feet), which is the depth of the Mariana Trench, the deepest known part of the Earth's oceans. This submersible is designed for deep-sea exploration and has successfully made multiple dives to this extreme depth. Other deep-sea submersibles, like the Trieste and the DSV Alucia, have also reached significant depths but are not as capable as the Limiting Factor in terms of operational depth.
