"The problem is that the massive barrage of bullets thrown by a Phalanx aimed at the sky will fall back on Gaza and cause casualties. Yes, Israel worries about casualties in Gaza and that is why they are not using Phalanx."

For mortars, you need a laser-based system. Photons aren't effected by gravity over the distances needed. And rate of fire should be higher. I suspect some Israeli defense lab (and a few US labs) are working on this.

I was thinking perhaps bullets that explode after a certain short period of time. It would drastically reduce the shrapnel that would fall on Gaza...would raise the cost per bullet from say a dollar to several dollars though.

Hats off to you for knowing photons actually are subject to gravity...most don’t know that :-)

The trouble with a laser system is cycling the capacitor bank quickly enough...and heating.
