I have a setting where the environment is constantly changing on the ground level. As a result, hover tanks are used more often than tracked or wheeled tank destroyers/IFV/APCs. The ground can literally change from semi solid, to liquid to jagged/rocky etc in mere minutes. So simply using boats or wheeled/treaded vehicles isn't a straightforward operation.
One of the issues I have with my hover tank design is that the recoil for main guns is pretty massive. Infact they can put some serious stress on the turret basket/rings during prolonged combat operations.
I plan on using rockets, something akin to a recoilless rifle or general unguided rocket round as the hover tank's primary offensive weapon. However, one of the issue's I have is the negatives of rocket rounds. Rockets in general are slow and far less accurate compared to their shell-based counterparts. What changes would need to happen to a rocket/recoilless rifle to make them more effective/close the gap between unguided rockets and normal tank shells?
While I don't require the same velocity as tank guns, I'd like to get as close as possible as armor piercing rounds are a type of round that hover tanks would be equipped with. Normal explosive effect warheads such as high explosive anti tank or the occasional high explosive/ HE squash head are also types of munitions that I'd like to field.
One idea that I considered is to use a railgun apparatus. As in that a rocket is attached to a sabot which is in between multiple rails. An initial motor fires off, then a few moments later the rocket goes down the rails and exits the "railgun" barrel. Note that this isn't an actual railgun that uses power to launch a shell. Rather a rocket has a motor that's slowly burning up to maximum speed before it goes down the rails. Kind of like the locks on the Space Shuttle that prevent it from launching/tipping. The issue with this is accuracy.
All fired rocket rounds are unguided. The two main considerations are speed and accuracy.
Edit:
I should clarify what I mean by unguided. I don't want an active guidance system that such as MCLOS/NLOS that can change the vectors of a rocket. However, things such as fins, rollerons, simple gyroscopes etc are fine if they are being used to keep the rocket on a general path in the direction it was fired at.
