That means the bomb load is also so small you can't see it with the naked eye. We don't need miniature bombs or a miniature bomber to deliver them. The B52 delivers a massive bomb load and serves a very real purpose. The B1B is also another great bomber, one they didn't build enough of.
With the capability of a drone and bomb technology, a small bomb that is guided can do serious damage.
A squadron of 10000 drones, with unfettered access around the world would be pretty impressive.
