It can be done on an individual basis. There is even a net deploying drone. But you’d have to have someone in visual range as you have to guide one drone onto another drone and deploy the net. While I suppose it’s possible, you’d have to have dozens of people spotted just about everywhere and they’d have to see the incoming drone. It might be at 10,000 feet. I think they generally fly high for direct line radio control. They’re getting sophisticated and using RF all over the spectrum, not just the channels “legally” allowed. So, jamming them is difficult and spotty at best.

Perhaps the net deploying drone could be automated, radar guided, and computer controlled. But they are short range so someone much closer would need to launch the drone. The logistics of that is problematic. “Hey, we’ve got an alert. Where’s the drone handler?” “In the can.”

You probably won’t know if the target has a tiny jet engine or a shrouded propeller. Not all interceptors can intercept all potential targets. You’d probably be looking at no better than fifty percent. At which point you have to look at the cost of this approach vs results potentially achieved. (I suspect even automated the interception rate would be low because the launch point and targets are so close together.) You have to look at all the probabilities along the entire kill chain.

Whatever you do, it will be countered and become less effective much sooner than the missile approach.

exactly!

all this talk of restraint is BS!

our whole national defense is based on kill enemy civilians!

how can we threaten to retaliate with nukes if attacked with nukes if we simultaneously say it is wrong to target civilians?

All governments in the world are hypocrites, who simply pick and choose who to hold to the rules and who to let break them and for some unknown reason (most likely oil) we consistently allow the truly evil ones to break the rules.

So a Shahed 136 uses rear props. It is 11 ft by 8.2 ft wide with a 110 lb (2,500 kg) warhead.

Range is 1,600 miles. Speed is 115 MPH.

Cost is $20,000.

It does not say what altitude. But low altitude.

These are not the quad-copter drones that the Uks are using.

The germans employed V1 rockets. They were 27.3 ft long and 17.6 foot wide. Their warhead was 1,870 lbs (850 kg).

- so about the new drones are smaller with a bomb 1/10th the size (excuse typo in prior post. 110 lb/50kg 2500 km was the range)

About 1/4 of the speed.

So how do we economically take down such drones.

Cost of each take down needs to be 1/10 to 1/100 the cost of the enemy drone ($20,000 => $200 to $2,000)

I wonder if one could take control of a drone and quide it to the al-Aqsa Mosque?

The way modern attacks work is you fire your long-range missile first. You coordinate with closer allies like Hezbollah to fire a saturation assault of lesser drones and missiles, so they all arrive at the same time. I haven’t followed it closely but apparently Hezbollah wasn’t involved. Either they said they’d sit this one out or Iran wanted to act alone to shield their proxies from retaliation.

The Iron Dome missiles are used against everything that appears to be headed for a vital target.

BTW, I’ve seen photos of an alleged Ukrainian version of the Iranian drone, and it has a small jet engine.

I studied the drone interception problem extensively after I retired and got with my old company, and they financed a trip to visit a startup that had the technology we needed to defeat drone swarms. Turns out the startup was funded by CCP princelings, so I had to drop it. But here’s the short part. It’s very, very hard to intercept a swarm attack with any of the current technology. The Iron Dome missiles work great, but they are pricey.

A drone swarm requires a counter drone storm.

The defense items that don’t intercept should be recoverable and relaunchable.

Something like the ducted fan RC jets would be the right cost.

The big question is what is the means to take down the enemy craft?

Too bad these pilots couldn't win in Vietnam.

We did. We just left before it was official.

sounds a lot like UK’s Chain Home plus Fighter Command system in WWII ...

Israel advances because of absence of DEI dragging them down.

110 lb or 2500 kg? Those are rather different..?

But these guys can easily be taken out with much cheaper AtA missiles, instead of burning a couple million each.

I know. Read the next line in post #7.

Israel is basically our battlefield laboratory.

If so, we have learned nothing. They have Iron Dome we have no effective air defenses here in the continental US. We are totally vulnerable to this type of attack.

Iron Dome got perfected because hamas continually launched rockets from Gaza - for years. How long would the US tolerate something like that if, say, Canada decided to just start launching missiles into our country? Would we “show restraint?” Would our response be “proportional?”

Hard to say. We haven't invaded Canada in a bit over 210 years...

Did you forget when they bombed The Baldwin Residence?

Fight the drones with drones.

How do you foul their propellers?

That would be a net gain, so to speak...

Look at the missile prices in the article,

Price isn't the issue at hand, replacement of used assets is. It will take months or even years to replace stockpiles used last night. Even that assumes there is no arms embargo from our professional war losing congresscritters.

And we know that because we have been attacked and couldn’t defend ourselves?

“Price isn’t the issue at hand, replacement of used assets is. “

If I recall, Israel is coproducing the missiles. I worked for Tadiran which was, at the time, the Israeli equivalent of GE. If the Israeli government decides, the Israeli production capacity will go to full auto. The holdup would be those items that are US only or limited by the ability of some supplier. Isarel will find substitutes. (They’ll just reverse engineer and steal the IP. Watched them do that.)

But here’s the issue. This will take time. Iran has demonstrated what they might be able to do. The other solution for the Israelis is to take out the Iranian capacity to build weapons while the Israelis work on replacement capacity. This can be done by, direct action, covert action, sabotage or convincing the Iranians that diversity is the key to defeating Israel.
