The warp core isn't. I don't think we've actually had a vote about the warp core specifically at all yet, just ones about the nacelle configuration.
Yes, well, I managed to miss the last vote, so making up for lost time.
Don't plug too much untested shit into the warp core please, it's not going to be much of a ship without a working one.
The Renaissance Nacelles are as fuel efficient as the standard ones Star fleet uses, just faster. So really the only thing we're gambling on is gas mileage. The issue is our Deflector screen is also directly hooked up to the Warp core like these new Nacelles. So if something goes wrong with that it goes straight to untested engines and we are far far less likely to catch there being an issue with an unknown engine over a known quantity. Which means if we're unlucky on the rolls we might have the entirety of the warp core pull a kablooie with little warning.[ ] Renaissance-class Nacelles
High speed, power/Fuel hog Not very efficient?
[ ] New Nacelle Design (Prototype)
Faster, sleeker, more efficient and just a improvement instead of something totally new.
So with that I say. Prototype time people. Remember the Council wants a shiny boondoggle full off all our latest shinnies.
