That's roughly 4 line AA or 1 support AA and 3 line AA with Tier 2 AA and 1941 AA techs. You can cut that down to 3 line AA or 1 support AA and 2 line AA with max AA techs.

That's basically something like 15-20 aircraft worth of production cost per division if you convert the cost of the AA guns to aircraft cost. I was thinking that maybe you could immunize the entire front this way instead of just panzer formations, but the cost is so prohibitive, you should have just built an air force instead.
