Down Periscope (1996)

Cmdr. Tom Dodge is not thought of very highly among his fellow Navy officers, so when he is assigned to helm an outmoded, diesel powered, rusty in a series of wargames, people don't expect much from him. Set on getting his underdog crew in line in order to win the event, Dodge must face off against his nemesis, Adm. Yancy Graham, who will do anything to see Dodge disgraced and finally kicked out of the Navy.
