The hydrodynamic performance of winged torpedoes has been investigated. It is assumed that the wing is mounted such that its center of pressure coincides with the center of gravity of the body, and that a ring-tail stabilizer is used. The resulting overall lift-drag ratios are presented as functions of the buoyancy-weight ratio. The ranges obtainable for the ascending, level, and descending flights are calculated. It is found that if the fuel weight is assumed to be always one-half of the displacement, winged torpedoes have longer ranges than those with neutral buoyancy only for descending missions. If the fuel weight, however, is assumed to be one-half of the total weight, the winged torpedo has longer ranges for all missions except steep ascending ones.
