the ships that players create are designed specifically for capsuleer use… for every playable hull there is an in game NPC version that dose not support a POD pilot. insert fleet navies and pirate factions.
concord is a 5 empire conglomerate that is headed up by a council and ship production has been traditionally overseen by the Jovian shipyards. thus the ships are far superior to any current player hull, they are also technically considered drones as they are not manned… there are variants that are fitted for human control however this portion of the CC fleet is considerably smaller and is primarily an expeditionary force used to run sorties in to Pirate and hostile space (null)
it is only in recent years that that there has been any faction capable of standing up to concord. the drifters have comparable tech to the jovians and are rumored to make use of capsule tech.
back to your idea, it would be a terrible idea to have players build the ships used for response fleets by NPCs. people would just not build or sell them to the buy orders, all space would become lawless.
I absolutely love the concord faction, the ship designs are stellar both old and new, their implementation is great to. they are the perfect response to hostile action, they always get their target. i would love to see more fluff relating to both concord and NPC staging locations in systems. a little sig here or there with fleets coming and going
