War

Mass producing FPV drones isn't hard or expensive, just order the parts from China by the container load, some assembly required, and batteries not included, even the Russians can do it. Ukraine needs 2.4 gHz and 800 to 900 mHz jammers ASAP, 5.8 gHz jammers too. Commercial fishing nets and chain link fence can help with defenses too. Anti drone guns are less effective, because spotting an FPV drone before it hits is hard to do, you hear them before you see them.

If I know the Russians, a lot of drones or parts are stolen and sold on the black market and Ukraine is probably buying them!

300 lbs. of HE might be able to take down or damage a rail bridge enough and the range looks like it is sufficient. Kerch bridge perhaps or with something western, since it's Ukrainian territory after all and the Germans will soon be delivering the means to take that out, but no targets inside Russia, they geofenced them.

HP will like this one.

Especially the second half.

Putin's toys?

Yep, tens of millions of dollars' worth of military planes for the cost of a dozen cardboard drones, and they are grossly overpaying for them! This will make Russian aviation pull back its horns quite a bit, it doesn't take that much HE to take out a plane. They obviously have a way to defeat GPS jamming, but they do have a lot of help from Uncle Sam too. The payload numbers in the video did seem a bit high, for that size wing, 45 kg is 90 fucking pounds! maybe 4.5kg?

I heard “four to five”
also, 45 kg is 99+ pounds

I know, I was just generalizing and thought I heard 45kg and said WTF!

99+ ≠ 90
that was the point

These are electrically powered stock, but could be fitted with petrol engines for greatly extended range I suppose. Electric aviation is reliable, easy to deploy in the field and convenient, can be computer controlled easier for things like auto launch and terminal runs into the target. From what I've read in the past they are expensive compared to the BOM for making them, any plant that can make card board cartons can crank them out by the thousands and even school kids can assemble them with hot glue guns for the most part. The propulsion system with a 7" prop costs about $20 and can be bought from China as a kit, the servos cost a couple of bucks a piece etc. Replace the FC with your own hardened custom one with your own programing, I imagine Uncle Sam is allowing them un-jammable highly accurate encrypted GPS access too.

The price point of suicide drones like this could be as low as $500 with custom electronics and extras, yet they can take out a military plane on the ground hundreds of kilometers away. 4Kg of HE landing on a fighter or bomber pretty well writes it off and they were accurate because they took out AA missile batteries too. This was a very significant attack and caused a lot of damage, especially when you consider what did the attacking and what it cost.

I guess I should have said over 90 lbs, in Canada it has been known that 1 kg=2.2 lbs for a long time, since the 70's when we went metric.

I caught that and figure the decimal point might have fallen away. That is why I always write 0.5 rather than .5, which could easily end up as 5.

The Ukrainians will be ready with artillery, HIMARS, minefields and cluster munitions for any human wave attacks, most will be dead before they get in sight of the Ukrainian lines.
