A submersible vehicle object ejection control system stores a plurality of pump speed command profiles. Each pump speed command profile is based on vehicle depth, vehicle speed, type of object being ejected, maximum noise emission magnitude during object ejection, and object exit velocity. The system also receives data representative of current vehicle depth, current vehicle speed, and the type of object being ejected. In response to these data, the system retrieves one of the plurality of pump speed command profiles and supplies pump speed commands representative of the retrieved pump speed command profile.
