They don't advertise any of their "new submersibles" on the website and the specifications they claim for Titan don't match any of their new submersibles; Titan is rated to go to the Titanic and not any lower. Titan isn't a previous version either. Unless they shelved the first Titan they probably just added some strengthening and called it a day.

I'm blown away that for a sub of that size and shape they used carbon fiber. The sub is positively gigantic and a cylinder is very susceptible to failure after repeated cycles. I'm pretty sure the claims they made about working with NASA and having a system to monitor the structural integrity of the sub are just BS.
