Electromagnetic propulsion may lead to increased propulsion efficiency; general theory of external field d-c electromagnetic propulsion is discussed and propulsion efficiencies are deduced for two, four, or six pole configurations; four or six poles and submerged displacements of 25,000, 50,000, and 100,000 metric tons are considered for length/diameter ratio 8.75 and prismatic coefficient 0.68; for six-pole arrangement, at 29 knots, thrust power is estimated to be 86% of electric power supplied at 100,000 tons, 83% at 50,000 tons, and 79% at 25,000 tons; values over 90% are reached at 20 knots; internal hull arrangement, supporting coils of superconducting magnets, refrigeration, etc, are discussed.
