What if it granted some promotion or XP to units? Maybe especially air and naval units?
I was thinking that would work as well. We don't have anything that really focuses on Air units except Willow Run, and I think Range I would work, coupled with increasing the science % from +15% to +25%. It would match up fairly well against Red Cross with the science bonus (less than Radio Telescope or Supercollider).
The other thing that I was slightly considering is a small bonus to Food in all cities (extra food from disaster preparedness).
