yep, but the main base is relatively good armored. All units got small re balancing here and there, especially resource costs changed for nearly all vessels, but the klingon units are still in the same relative position as they were before. The yard extensions are a bit cheaper then a fresh yard, but they wont feature an own repair slot. Klingon research, however, got a bit more expensive

Well, they're all part of the same structure, so it's only reasonable.

In practice, it may actually allow the Klingers to one-up the Feds when it comes to the destroyer spam.  Incredible, no?
