The Dinos and Clones who have been working closely on tanks and other armoured vehicles such as the T-55ZDM have formed a joint project group to look into the feasibility of using electromagnetic rail guns for a tank's main armament. The advantages of this would be the projectiles could be smaller (as they wouldn't need any propellant) and could reach higher speeds with range and penetration implications.
The problem up until now has been that EM guns require masses of power however the Dinos have been working on very compact power generators that generate large amounts of energy for some of their other weapons and it is felt that these may be applicable to the project.
Such a gun if possible could form part of the T-89FSU replacement planned by the HCS, the T-89X, and the follow-on to the ZDM the T-55ZDX.
