Another project involved the Lockheed Martin Cormorant drone aircraft. It would be launched from submarines, replacing the launch tubes of several cruise missiles. To reduce the risk of detection during launch, the drone would first be released from the submarine, which would then sail away. The drone would use compressed gas to push it to the surface, then it would use rocket motors to launch before using a jet engine when in the air. In order to return to the submarine, the drone would land on the ocean surface via parachute and be recovered by a swimming drone. The Cormant was cancelled in 2008 due to budget cuts.
