    The aircraft the S-70 operates with don't need to "fly" the S-70, they just need to set up a link to swap information... the Su-35 could use its wing mounted L band AESA antenna to communicate in broadband to send enormous volumes of information if needed and having a similar antenna on the leading edge of the S-70s wing means it can also hunt stealthy targets and pass on target data too.

    The information they send to each other from IRST and IIR sensors and radar will not be too much different from the same data coming from the S-70, or going to HQ.

    What are the sources stating the S-70 has an L band antenna in each of the wing leading edges?

    You appear to be misreading what I wrote.

    I didn't say S-70 had the leading edge AESA radar antenna that the Su-35 and Su-57 have.

    I essentially said IF the Su-35 and Su-57 could use their L band AESA wing mounted radar antenna as an L band datalink (the same frequency area that HATO Link 12 datalink communications operate at so it should be suitable) then the S-70 could use the same existing equipment to communicate back.

    Which actually reminds me that on the Su-57 thread it mentions new high frequency communication and navigation equipment... well that might be something that operates through the higher frequency nose mounted AESA radar in the Ku and Ka band which would be compatible with any similar AESA on the S-70.

    It also mentions surface based antenna with 360 degree coverage which suggests to me that the new radar/communication antenna is actually the skin of the aircraft, so they could use the same skin on the S-70 for the same communication and radar coverage.

    @BenVaserlan
    Actually, they would need just a radio or a data link operating at the same frequency of a L band radar for this but I think it's just logical to put an L-band radar instead. S-70 wing are perfectly capable to host it and could be used as a way for get an early warning against stealth planes allowing the Flanker to begin the fine search and tracking phase from an advantage position.

    And given the the S-70 has a longer wing leading edge than the Su-57, it could likely host a larger L-band array.

    Are you saying the S-70 doesn't need an L band AESA to communicate back with the L band AESAs of the Su-35/Su-57?

    As far as I know the L band wing mounted AESAs of the 35 and 57 are used for detecting stealth targets. I have seen a lot of speculation that it operates in the same frequency range as the HATO Link 12 datalink band which it might use to help detect HATO communication between aircraft and to and from various weapons they might use that use datalinks for communication, but I have not seen any Russian sources confirm such things.

    As an AESA it would be able to transmit and receive signals, though also as an array of TR modules it should also be able to communicate over fairly significant distances, so things like controlling drones deep in enemy territory might become and option too.

    For the S-70 it does not need something as big as an L band AESA array just for datalink communications, though I would think the ability to scan for stealthy targets at ranges conventional targets would be detected would be useful enough to install them.

    Just speculation.

    S-70 wing are perfectly capable to host it and could be used as a way for get an early warning against stealth planes allowing the Flanker to begin the fine search and tracking phase from an advantage position.

    Another factor would be if you have a flight of four Su-57s or Su-35s and each Su-57/Su-35 has two S-70 wingmen operating with them then you have four large fighters with AESA arrays to detect stealth targets, but also 8 drones with similar arrays and all 12 platforms can be used together where one or two aircraft might transmit a scan signal with all 12 collecting the reflections and returns and processing them based on their location... L band is used because it is not effected by aircraft shaping so the reflections are not redirected in other directions like higher frequency signals are.

    If the S-70 has these arrays then using their stealth shaping means they could fly high and much closer to enemy territory while the non stealthy Su-35s scan with their L band arrays for targets... being much closer the S-70 arrays will pick up targets even further away than the Flankers might simply because they will be closer.

    And given the the S-70 has a longer wing leading edge than the Su-57, it could likely host a larger L-band array.

    I always thought a flying wing design with volume for internal space for weapons and fuel and avionics would lead to a quite thick profile while where the internal space transitions to the leading edge and trailing edge of the wing there is going to be space at the front and across the entire rear of the wing surface you could put a radar antenna array, so a straight rear antenna the full width of the aircraft with gaps for the engine exhausts of course, though if they are above the wing surface the antenna could be complete, and across the front of the wing leading edge perhaps swept back 40-50 degrees... those three AESA radar arrays should give almost 360 degree coverage without physically needing to turn.

    Perhaps even a different shape with a flat front and a more strongly swept wing area and a flat rear for four sides giving complete 360 degree coverage without an external radar array like the A-100.

    For the bomber design inside that could be fuel and bombs and engines and people and avionics, but for an inflight refuelling plane it could remove the weapons and just have fuel, and for an AWACS platform just fuel for endurance.

    I suspect they would want to give them a lot of testing to work out what sort of roles they could perform... it is pretty clear they use them with fighters so Su-57 and Su-35 and Su-30 and MiG-35/MiG-29KR would benefit from operating with them (perhaps RATO assistance for carrier use?), but then with strike aircraft like Su-24 and Su-34 it would be rather interesting to use them to support an attack.

    A low flying Su-34 manouvering along ridge lines and hills and river valleys at near mach 1 with a full weapon load could be escorted by a high flying S-70 providing over watch at near supersonic flight speed... it could carry ARMs and ARHs to hit ground based radar and aircraft near the incoming strike jets... the S-70 could fly straight direct paths which should allow them to keep up easily with low flying high subsonic aircraft or missiles penetrating air defences low and fast, with the high flying stealthy unmanned platforms mapping out air defences and enemy forces as they light up.

    With a flight range of 5,000km you could even use them to support Tu-22M3M attacks where they carry long range AAMs like R-37 and the new model R-77s including perhaps a scramjet powered model with very long flight range...

    They could even develop a model for controlling drones that operates high over the battlefield collecting signals from drones and routes them to HQs to manage the information collected in real time and transmit that map of the battlefield with enemy positions to friendly forces below them.

    Even more "Hunters": UAC will start assembling military drones
    The corporation will produce heavy airfield-based drones

    The United Aircraft Corporation (UAC) will produce an initial batch of military drones, said the head of the UAC, Yuri Slyusar. According to him, this is a new direction for the corporation.

    There are several directions, ranging from an air-launch drone to our airfield-based heavy attack drone
    Yuriy Slyusar

    The head of the corporation stressed that in accordance with the contract, UAC manufactured flight samples, conducted tests and is now starting to create an initial batch. Slyusar expressed hope that UAC drones will take their rightful place in the line of Russian drones.

    S-70 "Okhotnik" UCAV - Page 25 Empty Serial production to commence 2nd 1/2 2024

    Post  Gazputin Fri Jan 26, 2024 8:20 pm

    sounds about right.
    Pilot build is from off tool parts where you confirm that mass produced parts do in fact assemble correctly ... as opposed to hand made parts
    and pilot build also means design has been frozen (for the first series)
    6 months should sort that out
    in any case many common parts are already used in other fast jets in mass production anyway ....
    massively reducing risks .... they are onto a winner here


    The serial assembly of the Okhotnik heavy attack drones will be carried out by specialists from the Novosibirsk Chkalov Aircraft Plant, it will begin in the second half of 2024, said Vice-Governor of the Novosibirsk Region Sergey Semka.

    According to him, now the Hunters are at the final stage of testing. It is known that the first flight of the drone took place in 2019 and was accompanied by the Su-57, and its rollout took place in Novosibirsk at the end of 2021.

    The UAV was developed at the Sukhoi Design Bureau, and is produced at the Novosibirsk plant (part of the UAC). Presumably, the Hunters will carry guided missiles, bombs in the internal compartment, as well as on underwing hardpoints.

    The IMF of Russia plans to strengthen naval aviation with the help of Hunters. The leadership of the fleet pays great attention to this issue.

    Earlier, the UAC announced plans for the mass production of attack drones.

    Nice.

    These drones can of course carry unguided bombs with guided glide bomb kits and release weapons from significant altitudes to achieve rather decent attack ranges.

    These drones wont be super stealthy but I rather suspect they would be difficult targets for medium and long range air defence systems to engage before they release their attack weapons, whether they be Grom glide bombs or an FAB-1500 with a glide kit...

    They will probably want to test a few at one time so producing a dozen or more would make sense so you could test them paired with a fighter or strike aircraft, but you could also operate them in teams working together.

    They should be a cheap way of boosting the number of air carried weapons you can get into the air at once.

    If we look at Ukraines experience if they want to launch HARMs or Storm Shadows such weapons are more effective launched from altitude but climbing to altitude to launch such weapons can be suicide within the Russian Air Defence network, so having drones that can climb up and launch multiple weapons before diving down and perhaps landing on a nearby motorway to seek cover as quickly as possible might be easier and more effective with an S-70 than with a more complex and expensive aircraft like a MiG-29 or Su-27 or Su-25 or Su-24.

    So the earlier prototype of the s-70 was used in Ukraine but apparently Su-57 pilot lost comm with it as it started to go other route. Su-57 shot it down and it crashed in Ukraine.

    Good way to test it for sure.

    Guarantee we know when it goes up and we try our best to mess with it electronically. Sounds like it was the prototype which is made for tough tests and even combat tests. Stuff like this does happen on very complex weapon systems. Problem is propaganda war is so thick. Almost everyone that discusses this stuff either copes and posts delusional panygerics on one end, or posts blackpilled doomer nonsense on the other end. It is all so tiresome. I'm not even going to touch paralays site. You translate the comments on a place like that during little propaganda wins for globohomo and you will only see snide doomer posting.

    Edit: Added a thought.

    Waiting for Karl to pop up and say it is Putins fault for not loading the drone with nuclear weapons for a strike on HATO.

    They were operationally testing a drone and there was a problem so rather than let it fly deep into enemy territory and possibly be recovered by the enemy they shot it down.

    No big deal really.

    It is not like the drone went rogue and started a friendly fire spree or something... or was hacked and landed at an airfield in Poland.

    Perhaps more than a dozen S-70 has been produced thereby allowing the RuAF to carry out several tests including shooting down the S-70 if there is a need.

    S-70 type UCAVs is the future. Manned fighter, strike aircraft will be retired because humans cannot compete with machines.

    Look at the thousands of programmers, content writers who have been replaced by companies with Generative AI.

    Currently, only four S-70 prototypes are reportedly produced. As for unmanned combat aircraft. The road is very long.
