Space docks only produce units. Nothing can be stored at a Space Dock.
Sarween Tools gives 1 free resource at each Space Dock.
If you are only using the 1 free resource for a build, you can only build at a Space Dock…..2 ground troops or 2 fighters or 1 destroyer or 1 ground troop or 1 fighter.
You may not build 1 ground troops and 1 fighter with the 1 free resource. You may build 1 ground troop or 1 fighter with the 1 free resource and lose the remaining 1/2 resource.
If you build 2 ground troops, they must go on the planet with the Space dock that produced them except for Saar. Saar may put them on ships.
You cannot put freshly built ground troops on your ships because the movement step that allows you to pick up ground troops occurs before the production step.
If you have 2 Space Docks, you may not combine the 2 free resources from Sarween to make a Cruiser or a PDS. The 1 free resource may only be used at its original Space dock. So you if you built 2 destroyers, 1 destroyer was built at each Space dock. Not 2 destroyers at one Space dock.
You could build 4 ground troops but 2 ground troops must be placed at the planet with the space dock. Newly built ground troops cannot be moved since Production is the last step. The movement step occurs before the production step.
If you have 2 Spacedocks with Sarween tools and 1 trade good. You may build 6 ground troops. But 4 ground troops goes on 1 planet and 2 ground troops goes on the other planet. You may not put 3 ground troops on each planet since a space dock produces ground troops 2 at a time.
Fighters are always placed in Space. Fighters are never put on a ship or on a space dock.
Fighters may never be without support unless they are Advanced fighters.
So if you wish to move Fighters, you need a ship that provides support.
Space Docks, Carriers and Warsuns provide fighter support.
If the unit providing fighter support is destroyed in battle, at the end of combat, any fighter not supported is destroyed.
If you do a transfer action with fighters, at no time may fighters be without fighter support.
You may never deliberately kill fighters by removing the fighter support unless you are retreating.
So for example: You have 12 fighters 1 carrier, and 2 space docks in a system.
You may not move the carrier out without taking 6 fighters with you since the 2 Space docks only supports 6 fighters unless….you are retreating the carrier in a space battle.
You may not…..just move the carrier out to grab a few ground troops and come back. You cannot deliberately kill a few fighters so the carrier can carry ground troops.
If you are in a space battle and the carrier is destroyed, fighter support is checked at the end of the battle and any unsupported fighters are destroyed then.
