 However, the production S-97 is projected to be capable of flying with either one or two pilots, or autonomously.Space for a targeting sensor has been reserved, however it will not be installed in the prototype aircraft.Based on the technology from the Sikorsky X2 demonstrator, the prototype S-97s will be powered by a General Electric YT706 turboshaft (the same engine used on the MH-60M Black Hawk).
