Goods Containers 10-50 TC
-------------------------

Externally mounted cargo cannisters, installed on any available missile hardpoints. (tech level 6+).

NB. Goods Containers are not to be 'fired' or jettisoned in flight!

As a precautionary step prior to purchasing any Goods Container, please "sell all pylon mounted weapons" in the shipyard first. You will see a message confirming your container installation if all goes well, and then you may verify your ship's increased capacity on the Market screen. 

A couple of examples, using FE Ships as a baseline:

Adder FE: 15 TC base + cargo bay extension = 30 TC + 1x Goods Container = 40 TC.

Cobra Mk 3 FE: 55 TC base + cargo bay extension = 70 TC + 4x Goods Containers = 110 TC.


Trade well!
Dor Reval of Xexedi, Space Grocer.
