In the Second World War, the most effective defence against Germany's V1 was getting a fast plane to fly alongside it with its wingtip under the V1's wingtip. They didn't actually "bump" the V1s, just got one wing into a kind of "ground effect" which caused it to roll beyond the capability of the gyro to compensate.

They're doing this to take down all sorts of stuff the Russians are lobbing at Ukraine.
