I don't know exactly, all I know is it's too much. It's way too powerful for a freaking Support killstreak... Support streaks over 5 = noob. Uav+Cuav is acceptable, anything over that = no skill. but that's just my opinion, if you want to help the noobs ruin the game by spamming the air with stealth bombers, EMP's and osprey airdrops, go ahead...

I believe where you put the circle and indicate the area the stealth should hit is where it starts to drop the bombs.  If you've ever watched one you know they drop like 5 truck loads of bombs on that area but the stealth is moving forward so the bombs are spread.  I'd say more like a freaking football field length of bombs. 

They always kill me, so I feel like the cover the whole map! 

Stealth bomber the no-skill multikill

I only ever play objective game modes unless I am playing Ground War or Mercenary, so the Stealth Bomber is very much the "no skill multi-kill" when I use it, or other players I play against for that matter. I often play against teams in Demo who have 2-3 of these stored up until the dying moments of a round or- most effectively, overtime. It usually takes 3-5 of the team out every time. The blast radius is pretty good in all honesty, at least as good as a Predator Missile. Stealth Bomber on Dome Demolition= almost guaranteed Multi-Kill during the dying seconds of a round.
