In the never ending quest to find RCEs, here's another one for you
Abbai researched Medical Bay I - RCE occured. Have I had a game go long enough to have a Medical Ship RCE before?
In the good news, in my current game some of the races have Ship 12 and Propulsion 12 and are fielding SuperDreadnougts with Ultra-Efficient Fusion Drives without problem. I'm currently the MEE, got the Shag'Toth to surrender whole (You have one planet, we have 80 planets, 12 Space Yards and 30 Base Mounted Ship Yards - Join us or willing or unwilling) and are at war with the Llort and Narn.
