A torpedo designed to simulate a non-offensive sea animal, like a penguin, in order to get close to a submarine without arousing suspicion.
In addition to the penguin model that inspired this idea, you could launch a school of dolphin-torpedos. Also, a school of fish-shaped charges being dragged forward by a motor concealed in the swarm.-- notmarkflynn, Mar 11 2006 http://www.awionlin...nter03/0103p15a.htm [2 fries shy of a happy meal, Mar 12 2006] State of the art U.S. sub http://www.mymerced...antsdelicollage.jpg [jellydoughnut, Mar 12 2006] Shachihoko robot (w/ quicktime video) http://www.we-make-...archives/008111.phpMaybe something more like this? [jutta, Mar 12 2006] Maybe they could quack?-- jutta, Mar 11 2006 Picturing the penguins from the animated film Madagascar.-- methinksnot, Mar 11 2006 I don't think penguins quack. It would be funny to fix small microphones to dolphins, tuna, and penguins that produce the same sound signature of a missile of the same size.-- jellydoughnut, Mar 12 2006 random, halfbakery
