I don’t understand why the author has such a narrow definition of FPV drones.

He talks as if reusable drones are a completely different category, that they are all toys designed for enthusiast racers… Generally he implies that a myriad arbitrary technical details are fundamental limitations of this paradigm, it’s a strange mindset.

Also, as others commenters state, isn’t a 43% success rate exceedingly high? Even if it’s 20% accounting for environmental factors and faults in manufacturing. How likely is it that a mortar does anything? Or a soldier with a rifle? Or anything else?

> When I joined the team, I was excited to work with a cutting-edge tool.

It sounds like he was imagining some kind of scifi adventure, but it’s always been clear that they are using cheap drones with tech that has been commonplace for a decade. And that’s completely fine, it’s intentional.

That's the whole question, and that's kind of the point that the article raises: the success rate does not matter. What matters is the cost. At the same cost, can you do more damage with other weapons or not?

A hit does not equal a kill. Killing a tank or an apc, takes a lot of hits from an FPV drone due to the small payload. I have heard quoted an average of 16 hits.

That's why you see videos trying to go in open hatches and the like. And that's why you are seeing cope cages. It doesnt matter how many chains or steel plates you weld on to your tank if you are hit by a TOW or a Javelin, it's still going to get you. They can penetrate more than a meter of steel.

But the FPV is carrying a DPCIM or a small RPG it's much less likely to penetrate a tanks or an apc armor.

> What matters is the cost.

Logistics matter too. How many FPVs can a company carry? How many fit in a pickup? Do you need a truck load to kill a tank? If you need like 10 to kill a tank, you need to do 10 attacks, either 10 people attacking the same target in quick succession or one guy 10 times.

A Javelin is pretty much one hit one kill, and the hit rate is supposedly at about 89%. So you need like one or two to kill a tank.

From what I have heard, bigger heavier reusable drones, that release their bigger payload are more effective than FPVs.

Ofc but javelin launchers and missiles cost $250k a piece. You get a lot of drones for that price.

And you need to be in a line of sight close to the target and not get hit by an enemy drone. And it requires some time to boot if I am not mistaken.

You need to be in line of sight, but not very close, it has a max range of 2 to 4 km depending on the version. Missiles in the spike family can also acquire targets after launch.
