I don't know why they always end up screwing up things like this. Even when they are directly involved in a project from design phase. They should have known that at 25 ton it's not possible to get such protection. But, hey who knows maybe DRDO peeps said it's doable. They also have a habit of overpromising.
But regardless this is a mess. I don't know how will DRDO and L&T folks would be able to increase the protection while staying within the limit. We haven't heard anything from IA yet regarding what kind of protection they really want? Is it just level 5-6 frontal arc or higher protection all side?
If it is just higher protection on the front correct me if I'm wrong maybe it's doable within the weight limit..
