Comment Triton Submarines (Score 2) 66
Triton Submarines makes 2-man and 3-man subs designed for 1000 or 3300 foot depths. "The 3300/3 played a major role in the expedition to capture the first ever footage of the Giant Squid" which a few of you probably saw on the Discovery Channel. They are one of a handful of companies designing models capable of visiting the Challenger Deep (repeating the feats of the Trieste in 1960 and James Cameron in 2012).
