Most of us would like to see that. But….
I am no naval engineer. But there is a fine balance that needs to be adhered to, when designing a warship that can sail and float with stability.
Weight, draft, length and beam of a hull have to be considered as dependent on each other within reason when designing, so that the finished product is stable and seaworthy.
If I remember correctly, @Anmdt had already touched on this matter in a previous post and stated that the I-Class had found her maximum allowable length with her current measurements. When designing these ships they have to take in to account that they need to be stealthy too.
After I-Class, our next move in Milgem should be a 135-145m long 4500-5000ton light frigate with a draft that is deep and a beam that suits such a ship. Also it needs to yield a type of hull that should be stable and allow deep/long VLS deployment. Hence releasing some of the constraints we have had to live with in I-Class.
