So to put your post in context? would you be so kind as to link the advertisement you are referencing? if LockMart is citing the max detection range as 50 nautical? would you suppose DOD would allow them to post the actual detection range of their most classifed 5th Generation aircraft.....

50 nautical is outstanding, but I'm rather certain that LockMart would be not reveal the actual detection range, which is likely in the 20 to 30 nautical mile range? that is entirely conjecture, but I imagine that LockMart's figure is very conservative.

So if you could link that advertisement, the wording would help us understand what LockMart is actually saying to their potential customers.

I don't believe LM would make such specific comments and if it did it would be widely quoted. That said, AWST did published some figures on what it considered to be the engagement distance of the S-400 against both the F-35 and F-22.

Yes, especially this one

Like how does a missile 'navigate around sensors' ?? Huh, didn't know that a radio wave can be physically evaded once you're in range. And also this..
I suggest you read up any book on electronic warfare pertaining to how ESM actually works.

How does sensor fusion of many used for targeting can cause a countering defense' system 'swarmed and overwhelmed' due to the said targeting sensors? Based on your writings here it seems to me that this LRASM missile is only using those sensors to help it target or perhaps an evasive move against anti-missile defense, though with the subsonic speed I wonder how effective it can be. However it's not swarming anything. It's not disrupting the defense' sensors, at the end of the day it's only a single missile..
It is about maneuvering to avoid detection, the collective fusion of networked sensors to address issues like aspect angle targeting and relying on passive sensors when appropriate. It is the collective effort of a group delivering on the principle that the sum of the parts is greater than the individual parts.

Sharing information and acting collaboratively, with what? Other missiles? If so then it goes back to the same old tactics of missile swarming..

Traditional saturation is simply each missile being pre-designated with targets or with re-targeting for those with data links to host sensors. The swarming technology that we are talking about in the 21st century as with the LRASM is not just re-targeting autonomously (not controlled through host sensors) but also the decision making on targeting and profiling of attacks are collectively determined within the swarm. Cooperative by definition means two way data exchange and in the case of swarms is multi data exchanges within the swarm. The so called swarming of the P-700 is simply a one way communication.

I would disagree that an LRASM is virtually undetectable.

We can see small control surfaces like fins, and indeed the smallish missile body would generate UHF radar returns

So we can expect to see multiple AWACs and destroyers operating UHF Aesa radars at different angles. Then sharing the results with CEC and generating missile tracks.

The US has already demonstrated this with with NIFC-CA using Aegis and E-2s.

And if there is a competition between AI and ECM, it is the defending destroyer fleet which has much greater capability than a bunch of small missiles.

But just for argument's sake, let's say LRASM is as stealthy, effective and as smart as you say.

There is nothing stopping the Chinese military from developing an LRASM equivalent.

And if both US and Chinese LRASMs make the Western Pacific a no-go areas for ships, that suits the Chinese military just fine.

China has the use of land based aircraft and missiles to achieve its objectives next to the Chinese mainland in the Western Pacific, whilst the US only has Guam some 3000km away.


Is the LRASM virtually undetectable? It is the context that is important. The F-22 is generally considered to be an order of magnitude more stealthy than the F-35. According to the AWST pictorial, the S-400 has a engagement range of 34 kms for the f-35 as opposed 21 kms for the F-22. This is a function of their RCS difference

. upload_2019-9-17_10-54-29.png

The LRASM's RCS is classified and so I don't know how stealthy it really is. Given that the F-22 is at least one order of magnitude lower than the F-35, it is not inconceivable that the LRASM has two order of magnitude or even three lower than the F-35. Translated this means the following engagement range :
2 X = 11 kms
3 X = 7 kms

At this range, the engagement window is extremely small. The prospect of collateral damage on the target is very high even if the LRASM is destroyed prior to impact.

No reason to believe that LRASM has lower RCS than even an F-35. A missile does not have enough space for sufficient RAM. RAM effectiveness is dependent on its thickness because the matrix or honeycombs within it, as well as ferrite particles embedded would need to be of a certain size to resonate against a particular radio frequency. No missile can afford the thickness required even for C-band or much less S-band. Thus a missile, solely optimized against X-band, will have increasing RCS against bands that have a lower frequency VHF > L band > S band > C band > X band < Ku band. A navy ship is equipped to cover an extensive spectrum. Something that can be detected first by VHF, L and S bands from a distance, even for a VLO object, will have the search radars queue the X-bands FCR right at its direction, and the result of this the X-bands will have a longer dwell time upon the target.

Optimum RCS is also frontal, and RCS changes and increases depending on the viewpoint. Search radars from a set of ships can also illuminate the target from all directions, CEC can gather all these dots, and the CMS will bring them all together.

Ship ESM can also pick up the missile's radar as it targets the ship, as well as the missile's datalink communication with its source.

To be fair, similar techniques can be employed as well against a Chinese LRASM.

Why is the F-22 "at least one order of magnitude lower than the F-35" instead just partially better and why should "it is not inconceivable that the LRASM has two order of magnitude or even three lower than the F-35" so people will come to their conclusion based on some hearsay from some "AWST pictorial" from some amateur hobby magazine as gospel bible of perfectly spied military spec intel of S-400 vs F-22/35? Thats a lot of chains made up of lots unsubstantiated very weak logical reasoning links jumping to hypothetical inference just like so called " the collective fusion of networked sensors" and then "maneuvering to avoid detection" and then "aspect angle targeting and relying on passive sensors" and then "It is the collective effort of a group delivering on the principle that the sum of the parts is greater than the individual parts" all the while we all know Russia have very capable if not the best in electronic warfare jamming and China is leading in 5G and AI too and they will just do nothing and let all this complex network fusion operation" happen in perfect Mozart like symphony without bother to disrupt any kill chain

You're still writing random crap like this? LOLOL That's like saying, "MiG-29 can reach mach 2.25; MiG-31 can get to mach 3.1, so even though Su-57's speed is classified, it's not inconceivable that it can reach mach 4.5 or 6!" After a sentence like that, the rest of the conclusions are founded solidly on your imagination.

Huh? The Russian P-700 Granit pioneered automatic coordination & target deconfliction between individual missiles in a salvo and ECM has been deployed at least since the P-500 Bazalt.

The P-700 was developed in the 70's. Do you seriously think that that we talking about the same technology and capabilities? The P-700 basically adopts a sequential instruction set in allocating an Alpha missile for target distribution in an attrition scenario. The communication and instructions is one way. This is entirely different to that of the LRASM as it is AI driven algorithm with no pre-assigned Alpha but rather operating in a swarm like manner with action sets driven by algorithm based on real time assessment of the electronic order of battle (EOB) as gathered through their collective ESM..


this:
is a pathetic sales talk, Brumby, as if you announced now the US should be able to fly to the Moon if such a program was started (while the US has flown to the Moon rather long time ago, and the Soviet Navy had operated swarms of supersonic AShMs for a rather long time:

LOL now noticed what the debater right above said

Do you have any evidence that the product is just sales talk or the technology itself is somehow unattainable? Is it the miniaturization of the ESM? Is it the use of AI.instruction sets? Is it the networking of data? What is it?

No reason to believe that LRASM has lower RCS than even an F-35. A missile does not have enough space for sufficient RAM. RAM effectiveness is dependent on its thickness because the matrix or honeycombs within it, as well as ferrite particles embedded would need to be of a certain size to resonate against a particular radio frequency.

Firstly do you have any evidence that the LRASM is highly dependent on RAM for its RCS reduction because 90 % of reduction is by way of shaping?

Secondly, missiles by nature has a lower RCS than fighter plane as a starting point. For example, a conical non VLO ballistic missile has a 0.01m2 RCS Can you nominate any fighter plane that is not dependent on shaping but simply RAM to have such level of RCS? You are simply making up an argument without reference to the technology or the context.
