Check out these rare launchers and purchase them for your Tengu, Sacrilege or Damnation. They are now available on the Jita market again, with sell prices at 275-280million.
Joint best performance in the game alongside Caldari Navy HAM Launchers, but with much lower CPU requirements. Powergrid needs the same as Tech 2.
These items are so rare they have collectable value, even if they are not named ‘officer’ modules. The price is only likely to go down if CCP does something to increase supply, so well worth it as a store of value.
