Starship manufacturing structure
Merc starports are mobile, orbital production facilities operated by Mira Han and Mira's Marauders. They deployed several of them in a skirmish with Raynor's Raiders and the Hyperion, but they were destroyed.
Merc starports regularly manufacture griffons, valkyries, and battlecruisers to attack the Hyperion and Valerian's Space Station. They take a lot of firepower to destroy, but should be prioritized for destruction to stem the flow of enemy reinforcements.
