I saw a movie some time ago and I want to no its name.. the story is..
A guy in the navy... he will want to be the captain of a nuclear submarine.
But his boss won't like him and will give him a challenge and will give him a diesel submarine and an useless crew but the dude will complete the challenges and will finally become the captain of the submarine he wanted..

If anyone knows this movies name help me out..

Ps the dude would have tattooed his genetial.
