It would be:
1. Somewhat useful against very big land targets, like towns or such.
2. A wee bit useful against targets like airfields, where maybe 10% would land withing the perimeter. These are 2000 lbs warheads BTW.
3. Quite useful as a desperate measure, especially since we all have tons of bomber perks....rows and rows of V-1's going for towns, fields, depots, etc.
4. Very useful as a distraction, - dots and dots on the radar...
5. Pointless against a moving target, such as fleet.
6. A most welcome target for the speed monsters, - the thing is cruising somewhere between 360 and 400 mph.
