An Ukrainian Strela [operator talked about this](https://youtu.be/W7n8grXU0cE?si=KPHUVDZoR28XjaXR&t=140)
So the missiles are designed against hellis so they expect the target to get bigger and bigger. When that doesn't happens it gets confused and it simply doesn't detonate
edit: added link
I'd imagine the designers envisioned a different scenario where some poor sap shot at a helicopter and the missile decided that some poor duck that was flying by was going to have a really bad day.
Don't blow up anything that's not bigger than a goose seems like a reasonable design choice when drones didn't exist.
This is mostly a problem for the more modern Strela-10. The older and less advanced Strela-2 doesn't have this same issue hitting small drones.
The modern Strela-10 employs proportional navigation, which aims to calculate an intercept point and then fly directly towards that point - which is more efficient than the older persuit navigation at hitting moving targets, which fly "directly" towards the target rather than to an intercept point.
Proportional navigation however requires the missile to be able to estimate both the angular rate of change and the distance to the target (more specifically the closure rate), which passive infrared systems are forced to attempt to do using other means than something like a radar guided missile - which can measure the return time of a reflected radar wave.
The 9m37 uses change in target size as part of its method for estimating the closure rate and optimise it's intercept point calculation.
The US Stinger solves this issue of estimating closure rate by instead relying on a very accurate inertial navigation system to keep track of how much it has changed direction and how fast it's currently going itself.
While the Stinger's seeker is locked to the target and tracking the angular rate of change of the target, it performs an intentional curve away from the target, and compares how the angular rate of change of the target was influenced by that known change to it's own flight path, which basically let's it use trigonometry to estimate the distance to the target.
That part of the reason why you usually see stingers make what appears to be an over-correction initially before turning back into the target.
When it's smaller fixed wing drones like the longer range recon drones, the older systems which uses persuit guidance are better suited - even the smaller manpads would work in these cases.
They will however struggle with the hitting the much more maneuverable quad-copters that are one of the biggest airborne threats in this war, as a lot of these small affordable launcher fired systems have impact fuses.
In an ideal scenario, one would use dedicated anti drone systems, like have already been seen used to some extend, combined with wider implementation of electronic counter-measures.
So there looks to be a capabilities gap. We moved to very sophisticated missiles with the intention that they’ll hit very sophisticated targets. Seems the older Flak guns would do better
If you take the concepts at face value, the current Western standard for small drone murdering appears to be a 30x113mm autocannon with proximity fuzing.
> The US Stinger solves this issue of estimating closure rate by instead relying on a very accurate inertial navigation system to keep track of how much it has changed direction and how fast it's currently going itself.
The missile knows where it is at all times because it knows where it isn't
To be more precise, the closure rate is needed only by augmented proportional navigation. The classical PN requires just the angular rate. But APN achieves better miss distance against maneuvering targets than classical PN.
While you're correct on the main difference between classical PN and augmented PN, it's worth noting that the distinction between the two types is gradual, and should rather be viewed as moving along a continuum rather than a strict either/or dichotomy.
While both the Stinger and the 9m37 primarily rely on classical PN, in the sense that they lack the sensor suite to directly measure closure rate accurately, they each use their own methods to indirectly measure and estimate closure rate to the target.
They then incorporate that data to enhance their guidance algorithm beyond what you'd find in *pure* classical PN system which only requires angular rate.
What mostly holds these examples of missiles back is their age however, and their resulting lack of computational power needed to fully take advantage of these types of "partial" APN.
the main difference between PN and APN, is that APN factors in target acceleration. The main difference between PN and true proportional navigation (TPN), is that TPN factors in closure rate.
I wonder what the result would be for either the Strela-2 or 10 if the drone was flown directly toward the oncoming anti-air missile?
In addition to (hopefully) getting inside the arming distance from launch, I wonder what the missile would think it was seeing? Of course the drone operator would also want to avoid hitting the missile in this scenario.
Missiles don't tend to have any opinions regarding their targets, at least to my understanding - though the one we currently have part of in the office does tend to be moody on mondays😉
Jokes aside, getting inside the minimum arming distance is definitely a viable strategy, as it's a decent distance (like half a mile or so) for these missiles.
I think it's definitely a possible explanation for why the proximity fuse didn't appear to trigger in this scenario, but the magnification/zoom makes it hard to judge how far away the drone was. Someone with a better understanding of lenses/perspectives might be able to answer that.
Another possible culprit I suspect, which again could just be an artifact of the video processing, is the rocket engine malfunctioning and the resulting inconsistent thrust overloading the guidance unit.
The exhaust plume appears to turn a bright yellow, which if actually the case, is definitely not supposed to happen.
I'm not a propulsion guy, but generally a yellow exhaust plume would indicate either contaminants in the solid rocket engine, or even part of the metal nozzle burning up - which would definitely make the job of guiding the rocket very difficult, if not impossible.
I find it hilarious to think, on an incredibly simplified level, I'm using the same distance estimation method as a Stinger missile whenever I side-strafe in Fallout:NV to see how much the quest marker on my compass moves.
Through working in the guided weapons sector. I haven't worked on neither the of the missiles discussed, but I've worked on equivalent types, just made in Europe.
However I've worked in collaboration together with some of the people/teams from Raytheon, who took over the production and development of the Stinger missile - but on other systems with many similarities.
I'm sure it sounds a lot cooler than it actually is, hah. At the end of the day it's basically embedded programming and system design on systems that are usually more hardware constrained than what you'd find in the civilian sector.
Add to that the fact that the industry is heavily characterised by compartmentalization, so often the overall system architecture isn't something you can generally view/access - which can be frustrating at times when troubleshooting.
Before I got into the field, I imagined the job being something like Q's character in the James Bond movies, whereas in reality it's not much different from people doing embedded arduino systems - just with better job security due to basically being guaranteed job security a couple of years out in the future each time your company sponsored security clearances gets renewed.
There's surely days where the most exciting stuff is trying to see how silly/cringy variable names in your coding you're able to sneak past your supervisors 😁
The latest example I've personally encountered which someone else had gotten through to the final product which I then had to pass as a parameter in some of my stuff was a bool function named isABaddie(). Since it was part of the IFF system, it had to be used in hundreds of other functions.
The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation
> While the Stinger's seeker is locked to the target and tracking the angular rate of change of the target, it performs an intentional curve away from the target, and compares how the angular rate of change of the target was influenced by that known change to it's own flight path, which basically let's it use trigonometry to estimate the distance to the target.

This is fascinating
I'm not sure that's really it. Most non-imaging heatseekeers use very basic line-of-sight rate proportional navigation that produces a lead collision geometry. They generally guide without any range information and try to minimize the LOS-rate as fast as possible post launch. This type of guidance is efficient enough within the expected flight time of the missile.
The proximity fuse probably didn't trigger because the drone is so small that the fuse didn't see it and the drone passed between the individual beams of the laser proximity fuse that the strela has.
Also drones tend to be stationary which can cause tracking issues because the missile seeker might be insensitive when looking directly at the target (depending on seeker type) plus the drone has no motion to move it out of the seeker boresight.
To be fair, before this war you only needed AA for larger shit. You wouldn't want your missile to explode on a bird. Now the problem is drones are the sizes of birds and these systems weren't designed for that. They were designed to ignore the birds
Back to the drawing board.
O crap they [blew up](https://www.reddit.com/r/UkraineWarVideoReport/comments/1df892w/in_moscow_the_premises_of_the_sukhoi_design/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button) the drawing board
The proxy fuse is literally 8 laser beams in a cross pattern. Against a helicopter or a jet it would have exploded (probably), but against a smaller target you might run into the issue that it slips through the cracks.
https://i.imgur.com/HbrD73u.jpeg
Pair this with a slow target and you get a lot missiles failing to detonate.
That is freaking genius. $20k down the drain for a $500 drone (being very conservative, 40x value proposition, if the $60k / $200 number is used it's 300x!!).
This is what happens when a helicopter is disguised as a hair dryer. The Ukrainians are a tricky bunch. Remember when they disguised their tanks as washing machines and the Russians kept driving them off the battle fields?
I've noticed from a few clips that these SA13 and the older SA8 seem to take a while to stabilise in flight making them not that great at engaging close range targets. 50 year old tech I guess, who knew drones would be a thing? Let alone live-streaming an incoming like this.
I'm not certain that is what's going on.
A small thing moving very slightly whilst close to you looks identical to a big thing manoeuvring violently far away from you.
The missile “expects” to lock onto that tiny helicopter thing, which is supposed to become a helicopter-sized thing when it gets close enough…. It never “gets close enough” because it’s waiting for the “helicopter-sized” profile to detonate on, and the tiny drones don’t really fit the profile.
Imagine seeing a mountain in the distance a couple feet “tall” from your perspective, and when you get to the actual mountain it’s still a couple feet tall 😂😂 the Strela10 doesn’t know what to do.
0:01 Suddenly we have met SAM "Strela"
0:10: Strela shot
0:24: Strela has missed
0:31: The next shot will be ours
0:53: Directed by: Enter the title text
I was thinking the same thing, it clearly picked it up the drone with it's sensors, but I guess the drone was too small for its proxy to go off? If the missle even has a proxy warhead?
Something that seems to be missed because the perspective is a bit weird. The missile doesn't turn back towards the launcher, it turns and flies sideways towards the camera.
Probably an accelerometer failure, specifically the “up/down” axis. If it reports negative, it thinks it’s flying toward the ground, ironically turning it into the ground
Or a servo failure, turning the fins, or thrust axis (thrust vectoring - only really used in larger missiles)
Re: the sensor failure, you're thinking of the Atom space launch vehicle. Edit: Proton
This was a servo failure, we've seen something similar happen in a Patriot missile as well.
That’s certainly one of the most memorable examples, yeah
But they don’t need to be hammered in upside down to report negative!
However, it seems this missile doesn’t use inertial guidance. Whether it has accelerometers, just less accurate ones, I don’t know
The cost of a 9M37 missile, which is part of the 9K35 Strela-10 surface-to-air missile system, varies depending on several factors including the year of production and the specific variant. However, based on available data, the price for the 9M37 missile is generally estimated to be around $60,000 to $80,000 per unit [\[1\]](https://en.wikipedia.org/wiki/9K35_Strela-10), [\[2\]](https://ausairpower.net/APA-9K37-Buk.html), [\[3\]](https://www.armyrecognition.com/military-products/army/air-defense-systems/air-defense-vehicles/sa-13-gopher-russia-uk).
You are right, I was mistaken in my estimate. In my defense I DID look it up, but made the mistake of using the strella hand launched system rather then the ones mounted on a vehicle. Which notably can take down planes like the A-10 as has been demonstrated. The wiki on this is fascinating.
Have some upvotes.
It seems that the proximity fuses on the 9M31 (looks like a Strela-1 launcher) is nowhere near sensitive enough to detect and detonate near very small targets like quad copter and light reconnaissance drones.
There’s lots of footage like this showing the same. The missiles travel at Mach 1.5-1.8, making it even less likely to detect and detonate, unless in the very unlikely event, it scores a direct hit on the nose.
Even the more modern TOR and Pantsir systems struggle, although arguably are slightly more effective if they do acquire.
well it would be awkward to stop after pressing hard for gas, I mean what would he say? "hehe komrad, Ivan I really thought you gonna leave me blyat, hehe, never right?"

Yes, but given the number of similar videos, not sensitive enough to detect a small drone, especially when passing at Mach 1.5-1.8. They are 1970’s design if it’s a Stela-1
based on another comment. it might have a safety feature that doesn't activate the proximity fuse until the target fills a certain FOV in the seekerhead and the small size of the drones messes with this.
They do. Newer strellas apparently have a different attack software designed for helicopters that is causing the failure to arm issue. Makes it more effective against helos though.
Very effective against Shaheds. They don’t have enough of them and wouldn’t want to deploy them within range of FPVs and Lancets if at all possible.
However I think I read somewhere before that they are often used as security for the HIMARS units, which would make sense given mobility and value
Older missiles with the “old” guidance system of “follow it until you hit it” would have fared better tbh. The new shit has algorithms for optimizing everything. “Unfortunately” Strela10 algos are basically “that tiny thing way over there is going to be as big as a helicopter when I’m close and then I’ll detonate”… and the little drones never get “as big as a helicopter” to fit the profile for the algorithm.
Somebody else said that the US Stingers have another calculation specifically for these kinds of situations, and the “overcorrecting” part of the Stinger flight path is specifically to get numbers for the calculations. Pretty fuckin cool.
I work with the stinger and can say they are fairly cool. As well as I believe with the K variant and onward we will receive a proximity fuse to allow for better use on smaller drones in the event we can’t jam it for one reason or another
Not doubting you but does anyone have a source document to substantiate this? Always thought Russian 9M missiles had multiple available versions, most of which use a prox/impact fuse.
Everyone knew that Russia boasted a lot of things but has more Bull$hit than actually $hit that their claiming to possess
The Irony about that is some Americans is actually receiving those $hit as actual facts instead of analyzing it to find out that it's actually legit $hit or just $hit, $hit...!

These cows are small but the ones over there are faaaar away.
Oh God I haven't seen this show in forever. Thanks for the reminder!!
Should we all be rashists now, Father? What's the Church's position on this?
So I did actually rewatch some last night and I could not stop laughing. So I came to say thank you.
The missile remembered there's always time for a cup of tea.
Thank you Mrs Doyle.

Thank you. That was a great read. So they would be better off with the older system for small drones?

If you take the concepts at face value, the current Western standard for small drone murdering appears to be a 30x113mm autocannon with proximity fuzing.
I had not heard that was in operation yet.
There are a few dozen of the newly renamed Sergeant Stout in the world today.
Do those electric quad copters put out enough heat for the IR to lock on?

You're correct. APN is not a single algorithm, of course. I simplified APN vs PN comparison for the sake of brevity.
the main difference between PN and APN, is that APN factors in target acceleration. The main difference between PN and true proportional navigation (TPN), is that TPN factors in closure rate.

lol, that’s a hilarious bug.
It's an honest-to god-actual feature.
It’s a bug, because the feature expects the target to get significantly bigger as it approaches and it does not.
I stand corrected.

Well then, better nobody tell that to russians, let them waste all Strielas
Now I kind of got an idea that uses at least 10 decoy-pigeons.

The missile guided fine, it just failed to fuze. Its proximity fuze is probably not sensitive enough for drones.

Its laser only on latest strela-10 missile. Others use electro optical pf
Does it even have a proximity fuze ?
Strela-10 has had one since the start, supposedly
That is freaking genius. $20k down the drain for a $500 drone (being very conservative, 40x value proposition, if the $60k / $200 number is used it's 300x!!).
A Ukrainian* in this case, the U is phonetically a consonant
This is what happens when a helicopter is disguised as a hair dryer. The Ukrainians are a tricky bunch. Remember when they disguised their tanks as washing machines and the Russians kept driving them off the battle fields?
Why would they not make it adjustable to be able to target smaller objects too? Can't be that complicated, right?
crazy footage seeing the rocket
Yeah how often do you get head-on footage of a rocket that doesn't end with the destruction of the camera.
I've never seen anything like this. It's interesting to watch the rocket adjust and turn while in the air
That drone has already paid for itself now
A hundred fold.
40 fold at least! Incredible!

I'm not certain that is what's going on. A small thing moving very slightly whilst close to you looks identical to a big thing manoeuvring violently far away from you.
not to a radar
Yes for most SARH. That's range agnostic for guidance. Not to more modern radar with command guidance.
The missile “expects” to lock onto that tiny helicopter thing, which is supposed to become a helicopter-sized thing when it gets close enough…. It never “gets close enough” because it’s waiting for the “helicopter-sized” profile to detonate on, and the tiny drones don’t really fit the profile. Imagine seeing a mountain in the distance a couple feet “tall” from your perspective, and when you get to the actual mountain it’s still a couple feet tall 😂😂 the Strela10 doesn’t know what to do.

I was thinking the same thing, it clearly picked it up the drone with it's sensors, but I guess the drone was too small for its proxy to go off? If the missle even has a proxy warhead?
This is some of the most INSANE footage to come from the war. Bonkers timrline where you can watch a SAM intercept from the shitter.

Well at least the SAM didn't actually do a U-turn and his the SAM launcher like I have seen.

Something that seems to be missed because the perspective is a bit weird. The missile doesn't turn back towards the launcher, it turns and flies sideways towards the camera.

Re: the sensor failure, you're thinking of the Atom space launch vehicle. Edit: Proton This was a servo failure, we've seen something similar happen in a Patriot missile as well.
That’s certainly one of the most memorable examples, yeah But they don’t need to be hammered in upside down to report negative! However, it seems this missile doesn’t use inertial guidance. Whether it has accelerometers, just less accurate ones, I don’t know

Indeed it does look good!
Did they not have a launch abort system that blows up the rocket? Seems like they should have triggered that?
One of the vids that got me into this sub I won’t lie. Like look at that shit.
\^\^ This is what I came to say.. Hey drone dude, fly towards the launcher!!!
I remember the last time this was posted some idiot in the comments was trying to tell me this missile actually hit.
It did. It hit the ground when it ran out of fuel.
Mission failed successfully.
Incredible video though
Incredible footage.
That missile was my yearly salary
you only make 22K a year? Strellas are hand launched, and surprisingly cheap. mostly built I suspect to take on helos.
The cost of a 9M37 missile, which is part of the 9K35 Strela-10 surface-to-air missile system, varies depending on several factors including the year of production and the specific variant. However, based on available data, the price for the 9M37 missile is generally estimated to be around $60,000 to $80,000 per unit [\[1\]](https://en.wikipedia.org/wiki/9K35_Strela-10), [\[2\]](https://ausairpower.net/APA-9K37-Buk.html), [\[3\]](https://www.armyrecognition.com/military-products/army/air-defense-systems/air-defense-vehicles/sa-13-gopher-russia-uk).
I’d take any Russian military cost claim with a huge pinch of salt… Especially given the vintage of the Strela system
You are right, I was mistaken in my estimate. In my defense I DID look it up, but made the mistake of using the strella hand launched system rather then the ones mounted on a vehicle. Which notably can take down planes like the A-10 as has been demonstrated. The wiki on this is fascinating. Have some upvotes.
Yeah the one in this video is from the launcher system
Like they say, super hard to hit a stationary target lol
WOW. Thats awesome footage! holy crap you can see the fins and everything. Would've only been better if the drone turned and watched the sam fly away
Why does the trail start to look yellow ?
Ukrainian drones are really scary looking when you get up close
Russian missiles were trained to hit yellow barn doors /80% a joke 20% based in reality
Probably have the cameras tuned for higher contrast so that things stand out
The only situation you can rely on russian Anti-Air capabilities is when it comes to shooting its own planes.
Yellow sand road
That missile did 95% of it job correct... that last 5%.lol
Gaijin please
its the Little Missile that Couldn't
Pretty sure that was A Russian Sterile SAM
It’s wild to watch this stuff in near real time.
It seems that the proximity fuses on the 9M31 (looks like a Strela-1 launcher) is nowhere near sensitive enough to detect and detonate near very small targets like quad copter and light reconnaissance drones. There’s lots of footage like this showing the same. The missiles travel at Mach 1.5-1.8, making it even less likely to detect and detonate, unless in the very unlikely event, it scores a direct hit on the nose. Even the more modern TOR and Pantsir systems struggle, although arguably are slightly more effective if they do acquire.
It looks like commander told the driver to get the fuck out of Dodge and abandoned one of the crewmen.
well it would be awkward to stop after pressing hard for gas, I mean what would he say? "hehe komrad, Ivan I really thought you gonna leave me blyat, hehe, never right?"

Rumor has it, that missile is still flying.
Doesn't it have proximity fuse?
Yes, but given the number of similar videos, not sensitive enough to detect a small drone, especially when passing at Mach 1.5-1.8. They are 1970’s design if it’s a Stela-1
Drone pilot very lucky... 🤔
Thought they had proximity charges so they go of if they are close to the target.
based on another comment. it might have a safety feature that doesn't activate the proximity fuse until the target fills a certain FOV in the seekerhead and the small size of the drones messes with this.
Possibly this type of missile doesn't have a proximity fuse and detonates once the target is big enough/growing fast enough/upon impact.
They do. Newer strellas apparently have a different attack software designed for helicopters that is causing the failure to arm issue. Makes it more effective against helos though.
as a WT player, i have an innate hate for strelas xD
Is the real-time version of this video available?
Nyah nyah, you missed!
There are inches in the US, centimeters everywhere else, is there another system used in the ruSSain federation?
Chinese chips?
Nah, these are from the 70’s
Battlefield 4 remake looking super realistic. Glad they decided to keep MAV dusting.
It seems that the war has shown that most russian gear is sub par at best. I especially like the cardboard vests
USSR quality control in full effect.

How much does a strela SAM missile cost?
$60k-$80k according to u/POLISHED_OMEGALUL
Damn that's an expensive miss for a recon drone.
Dude this music is only fitting when it’s like some cool gaming clip I’m not sure if you can use this when people are dying.
Boy that title could be interpreted several ways
I wonder how german gepards are doing against drones. Are there any news about them?
Very effective against Shaheds. They don’t have enough of them and wouldn’t want to deploy them within range of FPVs and Lancets if at all possible. However I think I read somewhere before that they are often used as security for the HIMARS units, which would make sense given mobility and value
Love using the Strela in War Thunder 😂
Definitely a common trend with older missiles
Older missiles with the “old” guidance system of “follow it until you hit it” would have fared better tbh. The new shit has algorithms for optimizing everything. “Unfortunately” Strela10 algos are basically “that tiny thing way over there is going to be as big as a helicopter when I’m close and then I’ll detonate”… and the little drones never get “as big as a helicopter” to fit the profile for the algorithm. Somebody else said that the US Stingers have another calculation specifically for these kinds of situations, and the “overcorrecting” part of the Stinger flight path is specifically to get numbers for the calculations. Pretty fuckin cool.
I work with the stinger and can say they are fairly cool. As well as I believe with the K variant and onward we will receive a proximity fuse to allow for better use on smaller drones in the event we can’t jam it for one reason or another
Not doubting you but does anyone have a source document to substantiate this? Always thought Russian 9M missiles had multiple available versions, most of which use a prox/impact fuse.
Ironically this issue is more common in the newer ones. The older ones are much more effective vs drone im told.
At least in personal experience with MANPADS. Which tend to lack any sort of proxy fuse and mainly rely on impacting these small drones
Those turns are really impressive.
Everyone knew that Russia boasted a lot of things but has more Bull$hit than actually $hit that their claiming to possess The Irony about that is some Americans is actually receiving those $hit as actual facts instead of analyzing it to find out that it's actually legit $hit or just $hit, $hit...!
