“Lockheed Martin MPUAV Cormorant”
Well the difference between the LM “Cormorant” and the http://en.wikipedia.org/wiki/EMT_Aladin used on Gabler’s Triple M is the price. You don’t have to recover such a cheap UAV. Another “UAV” that is already in use is the http://en.wikipedia.org/wiki/IDAS_%28missile%29. Four missiles fit in one standard torpedo tube. The missile is wire guided while the UAV can stay in contact with a special buoy called CALLISTO. http://maschinenbau.gabler-luebeck.de/en/entwicklungen/kommunikationssysteme/
The buoy and the missile are already operational. Cormorant made just some money for LM.
