"I think if I were a 32-year-old veteran commander in the Navy, I would make the decision that I'd been trained to do whether [or not] it would be the right decision," said star Andre Braugher.

The show is about a U.S. ballistic missile submarine called Colorado, which is declared a rogue enemy of the country when its crew declines to fire nuclear weapons without confirmation of orders.

Cast member Robert Patrick is a real-life military veteran and he gave the set designers high praise, saying, "I felt like I was on a real sub. I think they've done an amazing job recreating it."
