Speaks Words of Wisdom... On occasion
Wait what? You're telling me they can't build Battleships except for the places the Infrastructure was intact? that even planet developing into Forge Worlds couldn't build any of the void Industry to build Battleships anymore?
The parts about Grand Cruiser does check out considering the Battleships around and seemingly not used because of misunderstanding of the role. But still is that how things were? Suddenly the decision in Song of Peace to save the Shipyards capable of servicing Battleships at Baal and the nearby Forge World carry a lot more meaning then just 'its important for logistics and takes a long time to build'
Pretty much, yeah, there's a very small number of Forge Worlds in the Imperium with the capacity to do fresh build Battleships by the time of 40K, and most of those are the really powerful ones that are known across the Imperium. Most are refurbished salvage (Which is already pretty challenging for most Forge Worlds), and even then, there's only a very small number of classes they know how to build, and I don't believe there's a single Imperial Battleship design newer than 8,000 years or so that actually works, mostly just refit packages to already existing hull-types and useless boondoggles like the Invincible.
