Look up the capabilities of GBU-28 and other Bunker Busters first.
 help



These are a lot more expensive and difficult to deploy. They weigh several tons. You can't just strap one to a $200 quadcopter and fly it over.

How many $200 quadcopters delivering blow after blow to reach the equivalent damage to a single MOAB? Is it an impossible number to reach for those unable to deliver MOAB?

We're talking about bunker-busters - the MOAB is not a bunker buster. It's an airburst weapon designed to clear out large open spaces, and isn't effective against hardened bunkers.

No reasonable amount of quadcopters could match a bunker-buster. Surface explosions are not very effective against buried targets.

The weight and density of the bunker-buster is extremely important to its operation. When dropped from a high altitude, it breaks into the bunker with sheer kinetic force, and then explodes once inside.


Yeah, I'm not a military expert and confused the ordinance nick names. To be sure, the kinetic force is definitely something that cannot be recreated with drone swarm attacks.

Those are entirely different missions. A GBU-43 MOAB is used against soft targets on the ground. A GBU-28 is used against hardened buried targets. It's simply physically impossible to dig a big enough hole with a bunch of small drones or bombs: the only way to penetrate deeply enough is with a hard object moving really fast.

A MOAB apparently has the equivalent of 11tons of TNT. A drone carrying a grenade has up to 180 grams. So you need about 61 111 drones to deliver the equivalent explosive. At that point it might be cheaper to just bring the MOAB.

A MOAB can only blow up one target, 60000 drones can do a lot more damage. Just ask Russia how many tanks they have today, from the thousands they had a few years back.

61111 * $200 is only a little over $12million. The plane to deliver the MOAB is more than that. Also, why does it need to be a grenade? Why not deliver C4 or other explosive material?

The 200$ drones have a couple of kilometers range at best. You won't deliver them from 400 km away. You still need a delivery vehicle. But this discussion went off the rails, it's obvious fantasy land at this point.

>How many $200 quadcopters delivering blow after blow to reach the equivalent damage to a single <orders of magnitude larger purpose designed munition>?

How long do I have to piss on a steel plate to get the same effect as a waterjet cutter?

About the same answer.


When will the payload be quadruped robots that can walk in through the door?

The current crop of "cruise missiles" are cheap and low penetration. Burying things is not 100% safe, but it certainly increases the attack difficulty.

You don't dig a hole deep enough that Bunker Busters can't penetrate. You drive up to the root of a mountain where it meets flats and drill sideways. Getting your men out in case the entrance was bombed can be tricky though.

to use a GBU-28 or similar you need to establish air superiority first
