Farmplinker said:The only reason we have black powder produced in the US is because a model rocket company wanted to guarantee their fuel supply!
Ah, good old Estes. Used to launch their model rockets all the time as a kid. Later, around 6-7th grade, we would scrape out the black powder from the rocket engines for making our own firecrackers. Good times.
Happy they're still around. Had no idea they were the sole source of BP in the US now.

Uff black powder is quite temperamental shit ,and manufacturing plants blowing up is not question of IF but when.
A month or so ago a local 'fireworks' plant that was just getting ready to start 9mm production, blew up , the powder drying facilty disappeared one man killed, owner and his son were 80+ m away behind a storage building , father suffered 60% burns and son 8% , old man is still in induced coma and its not quite certain he will make it meanwhile they have been grafting tissue on him from the start. I met the guy last year when i went to buy some blanks for 'mole pistols' and a friend of mine used to work as head marketing in the company.(he mentioned to me that the industry average for a factory blow-up is 40 years or so ). Company was actualy only making custom fireworks like those used on big celebrations othervise they mostly did r&d for Chinese fireworks manufacturers.
Interestingly enough, their mentor,that taught them business, man from Italy , blew up a year ago , forensics say a stone lodged in his shoe likely caused a spark.
I imagine drones will put fireworks manufacturers out of business.

An interesting explanation about the increasing popularity of the 'FPV' style kamikaze drones.
I had thought it was mostly about having a bigger bang then the grenade dropping Quadcopters.
However it seems another factor is the very fast FPV drones are less susceptible to being stopped by Russian EW 'drone guns' as theres not enough time to aim at them and deploy the jammer / microwave.

Elon restricting Starlink usage, which among other things explains why we haven't seen more exploding drone boats used.

FPV drones are by leaps and bounds easiest to jam , hardest to fly , lose contact on their own when flying between trees and buildings, only really work LOS and in practice have very high failure rates , i would be suprised if 1 in 10 make it onto the target ,but they are cheap and DIY aspect is very important
What makes them difficult targets is a profile of use , reconnaissance or even grenade dropping drones fly high loiter on the spot and stay in the air for 20-30 minutes long enough for someone to use an EW gun on them. FPV drone has 3-5minute endurance so is typically done before anyone tries to stop it with EW guns.
DIY kamikaze drone is by far best bang for the buck , chinese recce drone is 6-10+K$(depending on the camera and size) and it might drop some bomblets + has a average life span of 2-5missions before EW takes it down , kamikaze drone is 500-700$ for one mission and has an RPG warhead. FPV drone offers much more bang for the buck than Switchblade300 even if 1;10 hits
Note the FPV kamikaze drone lost a signal about 50m before the impact as LOS was interrupted by a building in front of the target , the operator used a far too low angle approach where a steep dive could be used to ensure FPV LOS literally to last meter , that is why in heat of the moment many FPV drones are probably lost to pilot error. By the way same problem is inherent to miltary drones like switchblade , lancet, hero ....that is why they mostly have a simple AI to do the attack run even if the radio link is broken at the last couple of seconds.

When it comes to drone guidance over long ranges, Starlink enabled low-level approaches like that used on Strizh jet drones that attacked airbases that are harder to detect and fight (couple of Stizh drones actually hit trees and were lost due to flying so low to avoid radars), but commercial stuff enables 400+km deep guidance and telemetry, big problem is just that all these systems are line of sight , so further you fly higher you need to be to maintain LOS , which is a big problem for naval drones that need a flying repeater drone to provide a link.
One alternative is using a LTE/4G/5G network, which enables intercontinental range but not on the sea where there is no network coverage. Long story short enterprising individuals can for about 1000$ control drones from their couch anywhere on the planet where there is mobile networks, and if just using long-range radio link 500km is probably doable on sub 1000$ system , the problem is actually hitting anything of value as the radio link will break once plane drops below LOS (that might be hundreds of meters or even multiple kilometers from the target where the drone would need to continue the attack on autopilot.) , that can be augmented with use of an NVIDIA Jetson AI module, those are not expensive but know how to create targeting and controlling AI to fit your needs is another problem.
Starlink is not crucial to use of drones.

It seems that the Ukrainian naval drones don't need Elon Musk's Starlink to attack Russki ships.
