Thanks guys
Azel - go for your life, no need to ask. But I'm pretty certain that it is meant to be an engine... In the old FASA game its based on, the Graceful Flyer was a single engined ship with Damage Chart A (assigned to ships with forward mounted engines). Most other Roms were assigned Damage Chart B, for ships with engines mounted midship - I'm sure KF can confirm this too.
The station is kinda like a transwarp terminal/booster (or even the jumpgates seen in B5). Over long distances, the K'da don't rely so heavily on traditional warp travel and use these stations to increase their operational range. When the K'da strike, the element of surprise surpasses the Romulan/Klingon cloaking device.
They'll both be released soon.
