Just as I planned using the User Launch Calendar, I completed the ship and all 8 of its attack craft.
Carrying 8 fighters to places and retrieving them, the ship can move between planets and deploy a full wing around each. It can patrol planets on its own, but will require support craft to re-arm its fighters for multiple sorties, as its supply of weapons is meant for ship defence only.
Additionally, it has sensor wings for detecting objects far away, and multiple computers for automated docking of fighters.
Saving sandboxes to Google Drive turned out to be a (really) terrible idea, as these saves get corrupted. Instead, I will head to the game itself and use its email feature to send sandboxes on request. I wish I told everyone earlier.
