Magnetohydrodynamic (MHD) propulsion of ships has been studied by scientists and technicians since the early 1960's. The major reason for the interest is the potential for a high energy efficiency and low noise propulsion. The report gives a brief introduction to the basic principles of MHD propulsion and to the key technologies involved, where the major technological problem is the construction of large and strong superconducting magnets. Descriptions of two large scale projects, a Japanese full scale ship ''Yamato 1'' and an Americna project based on a large dipole magnet, is given. The anticipations of the experts with respect to the future developments is presented based on a questionaire and a study tour to Japan carried out in the autumn 1990. Finally is given a list of references and of institutions active in the field of MHD propulsion. (author) 83 refs.
