The Mark 50 torpedo is a U.S. Navy advanced lightweight torpedo for use against fast, deep-diving submarines. The Mk-50 can be launched from all anti-submarine aircraft and from torpedo tubes aboard surface combatant ships. The Mk-50 was intended to replace the Mk-46 as the fleet's lightweight torpedo.[1] Instead the Mark 46 will be replaced with the Mark 54 LHT.

The torpedo's Stored Chemical Energy Propulsion System uses a small tank of sulfur hexafluoride gas which is sprayed over a block of solid lithium, which generates enormous quantities of heat, in turn used to generate steam from seawater. The steam propels the torpedo in a closed Rankine cycle[citation needed], supplying power to a pump-jet.
