Months on End
You could be in love with the life of a submarine and aspire to become a top-tier submariner, but beware: a huge responsibility awaits you. We’re saying this because you won’t be spending several days underwater in a submarine.
Instead, you’ll be staying on the submarine for at least 90 days. While this is the minimum duration for most trips, it may extend to the point that you are on the submarine for almost six months!
