The arrangement and operational advantages of electric ship drives can be realized with superconductive dc machinery, without the traditional weight and efficiency penalty of conventional electric motors and generators. The Navy is developing the technology base for superconductive drive machinery to 60 MW per shaft, with operational evaluation of a 30 MW system planned for the 1982-1984 period. Content and status of this development program is presented and a twin 30 MW drive, reflecting current technology, is described. The superconductive electric system with fixed pitch propellers is compared with a geared CRP drive in a large gas-turbine destroyer, with resultant reductions of 30% in propulsion fuel, 14% in full load displacement and 9% in ship building costs for vehicles of equivalent mission capacity.
