Modern submarine torpedo attacks are not like in the movies
Take EVERYTHING in that article with a giant tub of salt.  The specifics of torpedo combat are some of the most closely guarded military secrets.<p>Take the following: &quot;These high-torque, permanent magnet electric motor torpedoes ramp up to speed in under a second. They go from sitting in a torpedo tube to 50 knots in a near-instant because they don’t have the mechanical lag and inertia thermal torpedoes must overcome during startup. &quot;<p>So much of that is totally wrong.  The torpedo has nothing to do with how it gets out of the tube.  Its propulsor (not a propeller) wont work from the back of a torpedo tube.  Starting it up in the tube, INSIDE the sub, sounds horribly dangerous.  The torp is ejected by force from the sub <i>and then</i> starts its engine.  Electric or thermal, it&#x27;s doing 50+ whether it wants to or not.  Once out of the tube, further acceleration potential is limited by depth&#x2F;pressure.  All torps have more than enough torque to start cavitating their propulsor in shallow water.  To continue to automotive analogy, it doesn&#x27;t matter whether your car is electric or turbine powered, acceleration is limited by how much power your tires can handle before spinning.<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=PjoholiW1ho" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=PjoholiW1ho</a><p>And this is why you don&#x27;t want that engine running prior to the torp leaving the tube.<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=KoElLaLcfOc" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=KoElLaLcfOc</a>
