First turns Research and builds.

[douglas]

Space yard ships generally don't get used for quite a while, as they need the Cruiser hull at a minimum, Battlecruiser if you want a good movement rate without master computers or any extras such as a quantum reactor. Much more common is space yard bases, which can be built from turn one with the Space Station hull. I typically put one or two space yard bases somewhere in the eleven turns of homeworld emergency building at the start.
