When a seeker missile is fired, the firing ship secretly records which ship the missile is targeted at. They thereafter move as ships do, with 2 ADF and 2 MR, and enough fuel for 12 ADFs. The firing ship can move the seeker in any manner desired. Naturally, ICMs can also be used against seekers. None of the other systems in this article are allowed.
Fuel is stored externally.
This is apparently a typo. I can't imagine that they really meant this. Total the Minimum Hull Sizes of all offensive and defensive systems on a ship. If this total is less than or equal to twice the Hull Size of the ship, all is well. If it is greater than twice the Hull Size of the ship, remove some systems.
