The Colonial Base in Delta Canopis is an abandoned military base and industrial processing plant. According to Senior Chief Petty Officer Tyrol that oversees the facility, it was inhabited by humans even though no records support previous exploration of the galaxy. Others suspect it may have been a classified military operation from the first Cylon War.
There is no current explanation what the humans were doing at the plant, nor why they left. All computer systems have been wiped and only the physical hardware remains.
There are ship systems, components, and even entire hulls. SCPO Tyrol is in charge of overseeing the retrofitting operations with modern controls and weapon systems.
