Unit construction only with city improvments???

[Alex 14]

I believe that units should not only be constructed with the right resources availble, but also if the correct city improvment is built. However this should only apply to some units, for example:

Missle Silo:
Nuclear Milssile
Cruise Missile

Air Base:
Fighter
Bomber
Helicopter

I would support your idea as long as they do not delay Missile Silos and Air Bases beyond the very early modern age.
