Not sure if this post should be in the "Junk Draw" or not. But anyway, here goes.
for some time now, tank guns have used a SABOT to increase muzzle velocity (and range?), and I was wondering if there was ever proposed a naval counterpart (enabling an eight inch shell to be fired further from a twelve or sixteen inch gun for arguments sake). I don't know if this method would have had any tactical advantage, any gun must have a means of aiming it and radar has a range horizon but there are other, older ways to spot the fall of shot.
Anyway, just curious is all.

Thing is, a sabot is pretty much a very fast round witha flat trajectory. and most of ship warfare depended on plunging rounds to pierce throuh decks. There was very little need for such a round owing to the distances that most ship warfare was fought.

I think you guys are confused on what a SABOT round actually is. A SABOT is a casing that goes around a smaller projectile to fill the space between the projectile and the gun barrel.

A tank SABOT round is a small, dart-like penetrator with a sabot around it to make it fit in the larger tank barrel. The tank sabot round is designed to punch through an enemy tank's armor at high velocity and with concentrated kinetic energy in a very small area, less than 1 sq inch. The SABOT does not increase the range or velocity of the round. It falls off shortly after exiting the barrel and the penetrator continues down range toward the target.

Navel Gunfire is more like Field Artillery fire than tank fire. It is has a ballistic (arcing) trajectory and is indirect fire, where the firing piece usually can not see the target. A sabot would not enhance the performance of the rounds at all if used in this manner. The result of using a sabot on Naval Gunfire or Field Artillery would be reducing the explosive effects of the round since you are decreasing the size of the round with the sabot around it. Also, a tank type sabot round with a penetrator would not be beneficial since NG and FA are area fire weapons and not point fire weapons. For pin-point accuracy, FA has laser guided rounds and are developing radar and GPS guided rounds that can give us that capability.

Hope that clears it up some.
