So I wanted to construct a Warship with a sub-compact KF core, as per Strategic Operations page 145, and decide that seeing as how the sub-compact core is stupid expensive, I'll use the smalles/lightest ship possible, which, under StratOps is 100,000 tons (same page). However, when I go to Tactical Operations, it says that the S-C KF core is only available to warships, and the maximum mass of a vessel mounting such a core is 25,000 tons (page 344).
Does the TacOps rule supersede the construction rules and mean that a warship with a sub-compact core can be made less than 100,000 tons (obviously, in this case, less than 25,000 tons)?
Edit: Forgot to add page references.
