|Okinawa class Shipyard|
|3D/3E, New Tokyo|
Constructed in 50 A.S. by Samura Industries, Yokohama Shipyard was the first orbital construction facility in Kusari, and also the first shipyard built by any House in Sirius. Originally it manufactured gas miners and gas transports for the H-Fuel industry, but it was eventually forced to concede the gas miners and transport contracts to its archrival, Kishiro Technologies. The shipyard has since then retooled to produce as smaller military ships for the Kusari Naval Forces, as well as large station components - a task few other yards in Kusari, including Yukawa, are big enough for.
Yokohama still does a considerable amount of business manufacturing space habitats and despite stiff competition from Kishiro, in 815 A.S. it was granted the license to continue its centuries old tradition of constructing Kusari Naval Force ships for another 15 years at least.
