It looks like the adoption of the Small Diameter Bomb into the F-22's inventory is going well. Thing is, I'm pretty sure they can drop these things from 75,000 feet and have them hit something as small as a tank. No idea how fast an aerodynamic projectile is going after it's fallen more than fourteen miles. I'm thinking that, for most purposes, just putting smart kits on lumps of concrete would be pretty effective for that kind of fall.
