Submarine \Sub`ma*rine"\, n. A submarine boat; esp., Nav., a submarine torpedo boat; -- called specif. submergible submarine when capable of operating at various depths and of traveling considerable distances under water, and submersible submarine when capable of being only partly submerged, i.e., so that the conning tower, etc., is still above water. The latter type and most of the former type are submerged as desired by regulating the amount of water admitted to the ballast tanks and sink on an even keel; some of the former type effect submersion while under way by means of horizontal rudders, in some cases also with admission of water to the ballast tanks.
