I've long advocated redundancy. But I don't think it makes sense to have 3 birds in space at the same time. That gives the enemy time to plan to take all 3 out.
We need replacements on the ground ready to launch. The first thing we do in war is establish air supremacy. Any attempt to knock out our space assets is probably going to be done in the first couple of days of war. After that the enemy is going to have limited ability and it's safe to put them back up there.
The only senario where it makes sense to have them in the air already, is if the enemy has a significant blind spot where we can hide them until we need them. For example if we parked them over North America in geosynchronous orbit until needed. But between Cuba and Russia, I'm not sure if there is a blind spot.
An enemy is going to first take out the satellites over their territory. Second they are going to take out satellites over our territory in hopes of disrupting us.
I'm assuming of course that our guns haven't been taken away and that the front is going to be on the enemies territory not ours.
