American channel: Bombs with the JDAM system in Ukraine often do not work lately due to the impact of Russian electronic warfare

The Western press continues to publish fragments of the so-called "large-scale Pentagon leak" on the Ukrainian conflict. The authenticity of this leak raises many questions, but the US military says it is investigating, claiming that "this is the largest leak of classified data in recent years."

These statements can be treated as realistic, you can - as an attempt to throw in disinformation, but the fact remains: the topic diverges on the network.

One of the American media that publishes "excerpts from classified documents" is NBC News. The material of this American media claims that the “Pentagon documents” that have become publicly available contain an analysis of the use of the so-called “smart” JDAM bombs in Ukraine.

From the report of the American channel:

One of the documents released by the Pentagon under the heading “secret” states that recently the bombs supplied to Ukraine with the JDAM system often do not work. It is assumed that this may be due to the fact that their fuses were not properly cocked, and also to the fact that due to the use of electronic warfare by the Russians, there are problems with the GPS signal.

Recall that a set of JDAM equipment is able to turn, in fact, any free-falling bomb into a "smart" weapon. The kit includes a GPS-receiver of high accuracy. Depending on the modification, such bombs can hit targets at a distance of up to 75 km (in horizontal projection) from the drop point.

Comments

[blackGRAIL]

Leaving aside the question of the authenticity of this leak, the leaked documents speak of 9 facts of the use of JDAM:
In 3 cases the bombs hit the targets.
In 4 cases, there was a loss of signal due to the effect of electronic warfare.
In 2 cases the bombs did not detonate due to a defect.
The US recommends that EW systems be destroyed by artillery prior to the use of JDAM and that bombs not be dropped if there are problems with the stability of the GPS signal.

[Orange Bigg]

JDAM, like a wunderwaffle, followed Javelin, Bayraktar, M777, HIMARS along the path of oblivion of the superweapon myth. Leopards 2, Challengers 2 and Abrams are next in line.

All the systems you listed are not "superweapons", but simply modern, effective weapons. Which "plows" every day.

[drone-expert]

In fact, 40 pieces destroyed only by the M777 Lancet in the video. If you think that this is the "success" of the M777 when 40% of NATO howitzers, worth as much as 3 of our tanks, were burned, then go to the doctor. Moreover, the main fire performance of the Armed Forces of Ukraine is now artillery of the calibers of the USSR and just the M777. There are few other howitzers in the Armed Forces of Ukraine or they are below the M777 class in terms of ammunition. In fact, if the GMLRS showed enchanting effectiveness, then the main NATO artillery suffered a crushing defeat. I generally doubt that after such an Epic Fail, the M777 has a future

[Woroshilow]

I read your thoughts here, immediately remembered the phrase from the movie Gangs of New York "What are you talking about ?!". How is the effectiveness of towed howitzers M777 and their destruction by kamikaze drones connected? If an UAV reconnaissance can detect a howitzer behind enemy lines and direct a kamikaze drone at it, this first of all speaks of the enemy’s shitty air defense / electronic warfare system. Hypothetically, if suddenly the Armed Forces of Ukraine with the help of the Switchblade 600 were able to destroy 40% of our Msta-B howitzers, would you say the same thing that they are shit? The effectiveness of field artillery is determined by completely different parameters, and not by the possibility of hitting it with the help of UAVs.

[Denis812]

I can't answer for my colleague, but I believe he was referring to the ability of Type 777 artillery to operate on a modern battlefield.
If drones like the Lancet are able to clear multi-million dollar systems the way they do with NATO art, then this does NOT mean that the art does not work well.
Yes, she is still capable of shooting somewhere. But its survival rate is below the plinth. The accuracy or hitting power of artillery has not decreased, but survivability is exactly the same parameter in combat.
This means that the people who are responsible for ensuring the operation of the artillery need to think very hard. It takes a lot of effort to merge dozens of artillery systems from drones in a month, you know. No West can withstand such a load.

[terms]

We all know this very well, the problem is something else, salophiles, as is typical of the Untermensch, hope for this technique as a miracle weapon, you don’t need to do anything, just press the button and it will do everything by itself)))

[blackGRAIL]

We were all looking forward to the appearance of the UMPC in the hands of our pilots and sincerely applaud it. And, let's admit that we really hope that the UMPC will finally allow our aviation to start operating / hitting targets in greater depth behind the front line. I don't know if you can call it a prodigy. And this is our analogue of JDAM. And the extent to which we or the enemy will be able to effectively use it depends on a whole range of things, including reconnaissance and countermeasures and the work of air defense.

[solar]

Nobody positioned JDAM as a superweapon. They said it was relatively cheap.

[topol717]

If there is no Internet, then the smartphone is looking for satellites for about 3 minutes. I don’t think that something is done differently in bombs. How long does it take for the bomb to drop?

[solar]

the bomb finds the satellites before being dropped.

[dementor873]

And in free fall, does it fly along gyroscopes or what? At the final stretch of km 10, shift the signal and it will fall in an open field.

[iljael]

Yes, it flies along the gyroscopes and checks with the gyro if the discrepancy with the gyro is more than 30m, then the correction from the gyro is ignored.

[Jafar]

Do you really think that when you load targets, you can't load ephemeris either?

[Ilya-spb]

I give a recommendation: do not give the "smart" bomb into the hands of the Krivoruk Bandera people. She may die. Or get captured.

PS I remembered a phrase from the movie "Wedding in Malinovka": - do not open it, it contains bonbas!)))

[drone-expert]

In any case, this points to the extremely crooked design of the JDAM. In comparison, GMLRS is practically indifferent to EW due to the high-precision laser gyroscope and a special modified GPS antenna that can receive the so-called amplified GPS signal, i.e. the place of attack is transmitted to the satellite and the radar of the satellite illuminates with all its power a circle of several kilometers where the GMLRS flies. This increases the requirements for the power of the EW signal by orders of magnitude.

Obviously, the JDAM was seen as an anti-Papuan weapon. There is most likely a bad gyroscope and GPS with protection only from spoofing. This can be suppressed even by Orlan-10 with TsN5

[terms]

In fact, in the West, all equipment is an anti-Papuan weapon, and in a serious war against a country with something more serious than sticks and slings in their hands, which has its own design school and factory (that is, its own physical production capacities), they are economically unable to pull out , because the entire military-industrial complex and the entire design school with a bunch of requirements and standards will need to be transferred to the production of balanced equipment. To be quite technologically advanced, with sufficient performance characteristics, but at the same time quite cheap, maintainable and cost-effective for quick assembly. Remember the lessons of the Tiger - the Germans became very uncomfortable when for each tiger ours produced dozens of 34-k both in terms of time and labor costs. Yes, 34 was worse than the Tiger, but not dozens of times. The tactics of application were improved, along the way, the 34 itself was finalized. Tigers have learned to break. The Germans, on the other hand, became generally sad when the allied plants began to be bombed, and the volume of tigers greatly decreased in terms of output. As well as quality. And he also needed a wide range of fuels and lubricants, which you can’t always bring up in full force, and the range of damage in which the tank had to be removed from the battlefield was much wider. This is all the economy of war, and we must not forget about it. But people do not change, just as the principles of the designed equipment and the school have not changed. Their machinery is efficient, but very expensive and requires a huge number of people per unit of product, material, operations, and a complex branching supply chain. That is, you can produce the coolest and most sophisticated equipment for 1000 rubles a unit, or you can produce a sufficiently solid one, but for 100 rubles. That classic case when 90% of efforts are spent on 10% of the way to achieve the goal, and 10% of efforts are spent on the remaining 90% of the way.

And by the way, it's pretty good. Even if you remove 2 bombs that did not detonate due to fuses, it’s still more than 50%. Quite good.

[your1970]

I wonder how realistic it is at all?
How much area can be covered in this case?
Where do the bombs fall if there is no Jeepies signal at all, in principle?

[EMMM]

Not much, this is a highly specialized weapon

[Napayz]

Probably, like drones - in case of signal loss, they fly "to the base"))))

[Cayz kfgby]

That is, if the external source of interference is strong, does the accuracy of the GPS signal really fall or be distorted?

[KCA]

It is distorted and very much, I won’t say about the military GPS, but the neighing carrier, the navigator handed me over, said that we were driving in the village of Sheremetevsky, it was, and we were driving along Manezhnaya Square

[Johnson Smithson]

can be completely drowned out, the coordinates can be distorted

[Boniface]

Only in the General Staff of the Armed Forces of the Russian Federation will they confirm whether this is misinformation or not! After all, they know where and what and when electronic warfare systems are used in our positions
They won't tell us about it.

Tests of the latest bomb with artificial intelligence ended in complete failure. The smart bomb categorically refused to leave the plane, clinging to the edges of the bomb bay with stabilizers and cursing.

JDAM smart bombs have suddenly gone stupid.
Who would have thought?
It will be interesting with the start of a full-scale third world war, when the entire satellite constellation of the United States and NATO as a whole fails ...

With the start of a full-scale third world war, ICBMs will not care what and how it is with satellite constellations. And to call interesting the time when the living envy the dead ...

1. The Pentagon has not officially confirmed the transfer of JDAM to Kyiv. The department said that they would supply (!!!) Ukraine with “precision-precision aviation ammunition”
2. From what carriers are they used?
3. Air Force General James Hecker caused a blizzard

shipped GBU-62

However, the only previously known GBU-62 variant appears to be the GBU-62(V)1/B, also known as the Quickstrike-ER, which combines the JDAM-ER kit with the Mk 2000 Quickstrike (Mk .64)
Naturally, they do not “explode”, those shallow waters are needed, dropping from a height of no more than 300 m and activation of the explosion only when an acoustic / seismic / magnetic signature of certain vessels is detected

[drone-expert]

HARM deliveries recognized only the "affected" Shell. True, there are rumors that the Shell was successfully hit by a cowardly contract driver. The Shell has a high center of gravity. If anti-aircraft gunners are usually guys with iron balls and see radar and anti-radar missiles, then the driver taken from Yandex Taxi is usually so pissed that he tries to get away from the rocket like Schumacher, as if speed decides something there. One way or another, only after this Shell on the side of the United States recognized the supply of HARM

[Sergey3]

I’m not catching up with something, but what about our super publicized air defense, which has no analogues in the world, if the enemy flies on outdated aircraft models near the front and still manages to bomb !!!! Where is our air defense anyway ?!

[drone-expert]

If you missed it, then in the previous series it was how the Ukrainians bombed our airfields with strategists))

With air defense, everything is OK, not OK with those who command not only them

[Sergey3]

Launching a drone and actually bombing are two completely different things.

[Beetle1991]

Are you talking about the unparalleled S-400 with a target range of up to 400 km?
And how do Ukrainians bomb with bombs with a maximum drop range of 75 km from the target (with an aircraft height of more than 10 km)?

[bessonov932]

The best air defense is tanks that break into enemy airfields! Questions to the tanker V.V. Gerasimov.

[ForWar34]

It turns out that JDAM and GLSDB are very vulnerable, since satellites can be jammed / distorted not only near the target, where it can reach the gyroscope, but throughout its range of 70 km. Conventionally, the radar detects an attack aircraft (for JDAM) or a MLRS launch (for GLSDB), then the jammer turns on and the JDAM / GLSDB flies in the wrong direction. That is, one radar and one jammer can cover a whole sector of the front and there is no need to put electronic warfare on every possible target. Moreover, electronic warfare does not need to work constantly when it can interfere with its own launches, but only respond to strangers.

As a result, this weapon is only against those countries that cannot pull off relatively simple electronic warfare and radars for detecting launches.

[Diger]

Quote from: ForWar34

since it is possible to jam / distort satellites not only near the target, where it can reach on the gyroscope, but throughout its range of 70 km

Please: draw a schematic diagram of how a "jammer" standing on the ground jams the signal of satellites (4x minimum, orbiting ~ 30000 km, some of them at the zenith, some towards the horizon) .... Moreover, it jams them for an object gliding at a speed of ~ 150 m / s from a height of > 10000 m and at a distance of > 50000 m ..
Just draw and think with your brains, even for your own development.

I repeat, once again for children who have passed the exam:
1. Jammer on the ground
2. Satellites in orbit at 30000 km
3. At an altitude of 15 km and at a distance of ~ 70 km, a reset occurs
4. The antenna on the bonba is located at the top of the la and receives a signal in the UPPER hemisphere.
5. Inverse square law + basic radar level.

Efficiency is the "result/cost" ratio. With this, modern Western weapons still have problems, which clearly shows the course of the database.

Silencing a civilian signal is one thing, but a military signal is probably another, otherwise HIMARS would not have been able to gouge the Antonovsky bridge in Kherson. The shells fell literally a meter apart.

Very simple: it creates a hemisphere, a zone of continuous interference with a radius of several tens of kilometers, in which the signal from the satellites is simply lost or becomes illegible. The whole question is in the energy supply of this "white noise". There is enough power - everything is a bundle.

I hope you have already applied for the Nobel Prize in Physics?
I understand that you have already passed the exam?
And the idea in your head about an electromagnetic wave (EMW) is like a jet of water from a hose?
Right?
That is, someone from 10 floors will pour water down from a hose (on a flying object with gps), and here you are such a baggy BOTTOM standing with a hose and knocking down the water jet of that enemy, preventing the consumer from getting a jet of water from above?

You think (without alcohol) at your leisure:
1. From above, a signal is emitted from the satellite (there is timing, time standard, distance to the marker, etc., etc. and all this in PRN)
2. You shine up on the RADIANT antenna “even to the point of a carrot spell”, she doesn’t care: she radiates, but does not receive
3. The receiving antenna or headlight monitor ONLY receives a signal from a known direction to the marker.
You can at least be irradiated with gamma rays (together with the ruby, located on the territory of the Russian Federation)
Gos doesn't care about that, she receives Markel's signal from uncontrolled Europe, the USA and Africa.

This is the usual aerodynamics,! If from a height of 10 km something planned for 75 km, it means that it has an aerodynamic quality of 7,5. (This is if the initial speed \u0d 7.5) And if it is, then it is lower than these 21) If my sclerosis does not change me, then the MiG-7 has it XNUMX (?) / delves into extensive memory gaps / :)

[Daishi]

Even 1 bomb out of 10 hits, it's no good, right

And now, in fact, if in Ukraine I still use aviation, why don’t we track it?
Yes, the plane can fly low, but the AWACS plane, what the hell is needed
And to drop a bomb, you need a height, the question is why we don’t shoot down before the bomb is thrown

[Denis812]

I am "pleased" how, in the talented hands of our journalists, the maximum range becomes a working distance.
In order to launch this charge at 75 km, the carrier must fly at a height of 10 km.
And in Ukraine, the Armed Forces of Ukraine fly at low level. So these jdams are like a cross to a Jew. It seems to be on the topic, but you can’t dress.
