    Also, Titan was the only sub they actually designed and built.

    Their first two subs were purchased. They didn’t design them, they didn’t build them.

    They used their first sub pretty much as it was. They used their second sub as a kind of trial platform to develop some of the systems that they later used on Titan - stuff like the game controller for steering the sub, for example.
