Building XL Torpedo Launcher II in EVE Online

What it takes to make XL Torpedo Launcher II, 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.

What goes into one run of XL Torpedo Launcher II

1 unit per run
Material	Per run	Can be built too
Robotics	768	yes - its own chain
Morphite	678	no - buy or mine it
R.A.M.- Weapon Tech	3	yes - its own chain
Quantum Microprocessor	483	yes - its own chain
XL Torpedo Launcher I	1	yes - its own chain

Production runs in whole batches. One run of XL Torpedo Launcher II gives 1 unit, so asking for fewer than that still means one full run - the game has no half runs, and rounding down would quietly tell you to buy the missing pieces.
