RE: [PSUBS-MAILIST] 223 miles per hour underwater torpedo

[Juergen Guerrero Kommritz <groplias2@yahoo.com>]

As far as I remember a description of the squall
topredo it in the popular mechanic article about
concrete subs.  This kind of torpedos are submarine
rokets and most of them can not turn and only travel
strait ahead.
There is one of these the baracuda that can be
manouvered moving the head.  
They all work with supercavitation some of them pump
air in the nose so the buble forms and they can travel
very fast.  Other use a special nose form to produce
this efect.
They are very impresive weapons, but as far as I know
very inestable so dangerous for the users to.
Best wishes
Jürgen
