Thank you for the detailed reply. Now what would be the requirements for the design? To replace all 130 mms with a decent 155mm gun that can be produced in numbers easily OR have a good quality solution like m198/m777? Based on your earlier comment where a requirement to use the design in a SPH, it looks like modularity is a key requirement here so my guess is we are trying to get a higher performance gun in the class of m198 at least; an m777 is probably not possible for us. If we just wanted a simple design then China would already have solutions available. But if we have the core metallurgical capability to manufacture high quality blanks, then theoretically we should be able to design any type of howitzers based on our requirements.
Now I am only waiting for some one to curse HIT and Bajwa about “if we can manufacture Tanks and artillery then why not a simple AR like SCAR!!!”
