BTW, why did that Chinese ship have the right cradle to lower the torpedo onto. Perhaos they should try the torpeded that goes 200mph underwater next time.
https://en.wikipedia.org/wiki/VA-111_Shkval
The VA-111 is launched from 533 mm
torpedo tubes at 50 knots (93 km/h) before its
solid-fuel rocket ignites and propels it to speeds of 200 knots (370 km/h). Some reports indicate that speeds of 250+ knots may be achieved, and that work on a 300-knot (560 km/h) version was underway.
[3] This high speed is due to
supercavitation, whereby a gas bubble, which envelops the torpedo, is created by outward deflection of water by its specially-shaped
nose cone and the expansion of gases from its engine. This minimizes water contact with the torpedo, significantly reducing
drag.

When a sub loses it's nose it probably means they were trying to 'upsize' and it went 'boom' instead.
