Managed to find this:
"The one thing the WYN lack is a shipyard capable of actually building ships (rather than just converting them). In 2264, the Orions will construct one within the Cluster on the condition that it remain under Orion control. The arrangement involves the gift of a CR and several light raiders (and a further payment of one light raider per year) to the WYNs, but gives the Orions one shipyard relatively invulnerable to attack"
also:
During the Andromedan Invasion, the Wyn found themselves in the unique position of being one of the only unassailable havens in the Western reaches. Because of their radiation zone, Andromedan ships were unable to penetrate the Cluster.
Turning this situation to their advantage, the Wyn acted as a neutral rescue and salvage service. While crews and vessels belonging to other races would never be held hostage, fees for recovering individuals and ships (which would otherwise be a total loss) were lucrative indeed. In fact, the revenues from this service were enough to finance the construction of a second shipyard within the cluster, futher increasing the Wyn capabilities
I've found this on the web and is mainly mentioned in 'timeline' info. If your really that worried I can dig out my mates old SFB manuals and have a look over the weekend....
Also, with ragards to the web site I listed above with the ship charts, I'm pretty sure the only BB's that weren't conjectural were the Klink and Fed ones. The Gorns and Rom's could never get 2 large warp nacelles working preoperely (hence the Klinks and Feds have 4 smaller ones) and the other races ended up concetrating on X-ships. Thats the main races like, not sure about the Andros, I think they found a half built Andro BB when they attacked a base if I remember the history correctly, but there was speculation is was just a DN. Also, the Tholians were supposed to have BB's etc in their home galaxy, whether thats relevant....
Anyway
