An acoustically stealthy, soft-bodied underwater propulsion system includes a central chord member and a series of successive muscle layers each having a skeletal mechanism and a set of actuators. Each skeletal mechanism includes a central vertebra, two or more actuator arms extending radially outward from the central vertebra and disposed axially symmetrically about the central chord member, and an actuator plate extending from a radially outward end of each actuator arm and oriented substantially transverse to the actuator arm. Each actuator is situated between an actuator plate from a first muscle layer of the series and a second muscle layer of the series.
