You may need to start a new game, or at bare minimum load portal into another system before you will see your changes take place.

I Have Tried Loading into another portal & I Have tried buying another one from Goblins Shipyard . Still no changes

Are you sure your editing the right carcass?

I'm Editing the one in GAME Folder

Is somewhere in game list of stuff included in caches ? As i am interesting to get some Panthers or Pumas instead of Gunslingers.

edit: got it, its in FloodTradeStations in NychRareShipsList, easy to add there both.

I mean the carcass itself... there are two mothership_uels for example, one is used by SAM I think.

Yeah I Also have tried Changing the values in both of them but still no changes :confused:

What exactly are you trying to change?

I'm trying now to make torpedo launchers available for motherships by editing carcasses.xml and the model, but it seems to me like the game didn't accept any change. Do I have to start a new game?

I had the game running with the non-pirate Mastiff ("Mothership_arba", arba_base_player.imd if I'm correct?).

Editing weapons loadout is a lot more difficult because not only will you need to edit the carcass, but you will need to add physical hardpoints on the IMD file and add UI support in the Texture/interface/carcass folder.

PS. However, missiles generally do not work well on motherships because you will have to dock to a station every time you wanted to replenish missile loadout, and there is no way to toggle missiles on/off for a mothership... although I am curious if a missile turret is doable with unlimited ammo but weak missiles.
