I didn't take offense Luki, I'm a member of this team and still badger about when the next release is. Some folks don't know the time though, wasn't sure who has an idea of this project's size.
Interesting piece of info, Spin. My explanation either way would be an increase in sub-lightspeed travel, note the large thrusters on the back. Besides, if the Enterprise-D series finale can have 3 nacelles, we can have 4, at least it's in a pair

.
By the way, the mod team is currently testing the 2.5 Alpha B. The next release will be for SoaSE's mini-expansion, Entrenchment. Entrenchment opened too many doors to modders to ignore, and it actually decreased my game loading time to about a quarter of what it was in the last vanilla SoaSE release.
2.5 Alpha B includes 2 Kzer-Za ships, and the number that will be in the final release of 2.5 should be a half dozen or more. I think (note the
I and
think) each 7 Deadly Sins race should see at least one new ship or station, and balance should be better. Since this is an Alpha, not even a Beta release, much more than that may appear before its final release.
