 * All submarine movies have a dive scene: K-19, Hunt for Red October, U-571, USS Alabama, The Enemy Below ...

Sub Version?) of this trope, with a submarine doing an "Emergency Blow" of its ballast tanks to send the submarine rocketing to the surface to avoid an incoming torpedo.

 * One of the reasons why Das Boot is so great: it plays the trope straight then subverts it.
