Same ship, different modules

Me and a friend both have the Phobos (rank 7 imperial gunship). I have many options in the hull module slots, but he doesn’t, for example the Missile Pylon thingie is missing for him. The Wiki says that he should be able to access all but one hull module upon reaching T3.

 

Is there some hidden mechanic that limits the availability of modules, other than tier of the ships faction?

Yes, some modules are unlocked at rank 8 and rank 9. If your friend still haven’t reached those ranks, he still don’t have all modules available.

We both have the same ship, the rank 7 Phobos. Mine can equip missile pylons, his can’t. His hull module list is missing several T3 modules.

I thought the module availability depends on ship tier, but apparently it doesn’t.

No, it depends on ranks. Once you reach a specific rank, you unlock new modules. This means, that you can equip R8 module on R7 ship, because these ranks are the same tier, but you can’t equip R8 module on R7 ship if you don’t have a R8+ ship yet. You will de-facto unlock new modules in the process. Unlocking - depending on highest player ship rank. Modules - can be equipped on the same tier even tho you unlocked this module later.

Also, a few modules were removed from purchasing and are not vissible for the ones who did not buy them when it was available (like targeting coprocessor at T3), but they are available to use and equip at any time for who bought them before that patch.
