Building 650mm Medium Prototype Siege Cannon in EVE Online

What it takes to make 650mm Medium Prototype Siege Cannon, straight from the game's own blueprint data: every material and how many of each. The calculator above prices that list at one region's orders and draws the whole chain as a graph.

Nobody manufactures this

650mm Medium Prototype Siege Cannon has no blueprint: it is mined, refined, looted or handed out, not built. The calculator above still works for anything that does have one - type a name into it. For what this item is and what it costs, see its item page.
