Abstract
An extensible torpedo has a body, a cavity within the body and a water reactive material in communication with the cavity. A mechanism selectively positions the cavity between a first volume and a second volume and also selectively positions the torpedo between a first length and a second length. The second volume and length are greater than the first volume and length. The mechanism introduces ambient water into the cavity in a volume that represents a stoichiometric balance with the amount of water reactive material.
