Is there any movement around the world for an universal launch system on submarines? I mean, why not launch torpedoes vertically too? You get the same advantages as adopting an ULS as on ships with space savings, easier maintenance, scale, flexibility, etc.
All VLS are only able fired missiles and as have pointed right Iron Man it is useless for torpedoesVertical torpedo tubes would not be immediately reloadable by the crew, unlike horizontal tubes. If you look at the nature of VL tubes on subs you can easily see that they take up far more room than munitions stored horizontally. You also wouldn't be able to launch torpedoes vertically if you were close to the surface or on the surface.
