The Making of the Deep Submergence Vehicle (DSV) Limiting Factor – Nick Verola [video]

I wonder what other projects require so much titanium.

Supposedly the F-14 with it's swivel-swing has a big 1 ton titanium box at the center. And there's a lot of those jets. But this 1.5m sphere that's 9cm thick is quite the huge single chunk of titanium.

TIL that Gabe Newall of Steam bought the Limiting Factor fairly recently.
