[context: comment in relation to the original title, which has been changed, listing the drones as using 40mm warheads. No negativity meant to the original poster, I was just trying to be more factually accurate.]
I believe those are PG-7VL warheads, which makes them 93mm.
The 40mm number comes from the fact that all RPG-7 rounds have 40mm bodies for their tubes. The warheads are usually over caliber of 40mm though, except for a few anti-personnel rounds.
This picture looks a Kristoffer Zetterstrand painting. (This sounds like I'm very cultured until you realize that is the guy who did the Minecraft paintings)
Ukrainians literally built nearly everything the Soviet Union flaunted as their highest tech innovation. The retards up in St Petersburg and Moscovia are all useless politicians, grifters, and wealthy elite all did nothing for decades and claimed they did the work.
My proof is witnessing the current Russian Federation attempting to invade Ukraine and all failing because they all relied too much on Ukraine to fucking carry them on their shoulders.
Ukrainians literally built nearly everything the Soviet Union flaunted as their highest tech innovation.
Yet another supporting point to your statement. Sergei Korolev, the father of the Soviet Union's space program was born in Ukraine in Zhytomyr, a town just west of Kyiv. He was the innovator that came up with the engines and the rocket that put the first human in space.
