An example can include a pod detachably coupled to a hull. At least one thrust generator can be fixed to the pod. A power source can be mounted to the pod and slideable fore and aft. A power source actuator can be coupled between the pod and the power source to translate the location of the power source with respect to the pod. A sensor can be coupled to the pod to detect a pitch of the hull and provide a pitch signal. A controller can be coupled to one or more of the power source, the power source actuator, the first and second thrust generators and the sensor. The controller can maintain a pitch of the hull by translating the power source within the pod in association with the pitch signal.
