Prospective Russian AWACS: Choosing a Platform

A view from heaven
One of the most important elements of the Air Force (VVS) / Aerospace Forces (VKS) are airborne early warning and control (AWACS) aircraft.
The Russian Aerospace Forces have a critical shortage of this type of weaponry, especially compared to the armed forces of other leading countries in the world. First of all, this is the United States, but they are quickly being caught up by China, which has many developments of AWACS aircraft, both manned and unmanned, and other countries are also trying to ensure the presence of these machines in the ranks of their Air Forces.
The problem is that the effective range of use has increased significantly in recent times. missiles "air-to-air" and anti-aircraft guided missiles (SAMs), and there is a tendency for it to increase further, which has increased the risks of destroying AWACS aircraft - we previously talked about this in the material "An Endangered Species: The Uncertain Future of AWACS Aircraft".

The American AIM-174B Gunslinger air-to-air missile has a range of about 240 kilometers
Given the complexity and cost of AWACS aircraft, the increased risks of their destruction are forcing the armed forces of the world's leading countries to seek new approaches to ensuring situational awareness from the air. One of them is distributing the AWACS function between several small-sized manned and/or unmanned carriers, and today we will talk about the capabilities that the Russian Aerospace Forces potentially have in this area.
Limited choice
Based on open data, the Russian Aerospace Forces have problems with the creation of AWACS aircraft not only in terms of the radar complex (RLK), but also in terms of the carrier. Earlier in the material Aircraft AWACS for the Russian Air Force: fast, a lot, inexpensive We considered the possibility of creating a "ersatz" AWACS aircraft based on the promising Il-114 aircraft and the Irbis radar system of the Su-35S aircraft, which has proven itself well in the special military operation (SVO) zone.

However, the development of the Il-114 aircraft is delayed, and when and in what quantities it will enter serial production is completely unknown. Of course, one can consider the possibility of using the Tu-214 aircraft as a carrier platform, but these machines are also produced in a fairly small series, and their large dimensions and low maneuverability make them vulnerable even to low-maneuverability air-to-air missiles and long-range SAMs.
What other options do we have?
There aren't that many of them. With a small aviation We have serious problems in general, to the point that we have not been able to create a replacement for the “maize” for several decades, so, in fact, there is not much to choose from, as a result, we cannot yet create something like the American Grumman E-2 Hawkeye.

The American E-2C Hawkeye AWACS aircraft and the Chinese KJ-600 – it’s a pity that we are unlikely to succeed in this, at least in the foreseeable future, both due to the lack of a comparable carrier aircraft and the lack of a radar system for it
Recently, the topic of using UAVs as a platform for placing AWACS equipment, that is, only the “detection” equipment, while “U” – “control” is taken out. In particular, in China, the AWACS UAV WZ-9 Divine Eagle is being developed, specially designed for detecting low-observable aircraft.

With unmanned technology, we have the opposite situation: while small UAVs are being actively developed and mass-produced, there are certain problems with medium and heavy ones.
The medium-altitude Orion UAVs have too little payload capacity – they can be used in combination with a low-power radar station to detect kamikaze UAVs or unmanned boats (UBK) of the enemy, but not to solve the tasks of seizing air superiority. The same will most likely apply to the heavier medium-altitude Altius / Sirius UAV.
There is a project of the Gelius-RLD UAV – a radar patrol, but, apparently, this machine exists only as a concept and a model. Nothing is known even about the creation of the first prototype – it can be assumed that the Gelius-RLD UAV will appear in the Russian Aerospace Forces when machines of this type in Western countries will already begin to become obsolete, since they are about to be replaced by low-observable machines capable of surviving in combat with a high-tech enemy.

Model / prototype of the UAV "Gelius-RLD"
For example, based on open data, in the US Air Force The RQ-4 Global Hawk strategic high-altitude reconnaissance aircraft will be replaced by the extremely stealthy RQ-180 White Bat UAV.

However, it is in the niche of stealth UAVs that the Russian Aerospace Forces have a compelling argument – this is the heavy stealth UAV S-70 Okhotnik, made according to the “flying wing” scheme. Based on open data, this UAV is in the final stage of development, accordingly, it should be closest to serial production. Thus, the S-70 Okhotnik UAV may be very interesting as a platform for the radar complex, which is part of the spatially distributed AWACS.
Can we consider the S-70 Okhotnik UAV as a platform for an AWACS aircraft or will these machines be in demand in the Russian Aerospace Forces to solve some other priority tasks?
UAV S-70 "Hunter"
The program to create the Sukhoi S-70 Okhotnik unmanned aerial vehicle is one of the most classified in the Russian Aerospace Forces. Based on the data published in open sources, two main scenarios for using the S-70 Okhotnik UAV can be considered.
The first is the autonomous use of the S-70 Okhotnik UAV to destroy any ground targets using guided weapons (I would like to hope that they do not plan to use this combat vehicle to work with unguided “iron”).

The second is the use of the S-70 Okhotnik UAV in conjunction with the Su-57 fifth-generation multi-role fighter as a “faithful wingman.”

High-intensity armed conflicts, such as a special military operation (in Ukraine) or the war between Iran and Israel, require combat aviation to exert enormous strain to employ thousands - tens of thousands of high-precision missiles. weapons long range.
In Ukraine, the main precision munition used by the Russian Aerospace Forces aviation is the unified planning and correction module (UMPK) aerial bomb. Using UMPK aerial bombs with the S-70 Okhotnik UAV is unlikely to be practical in terms of cost-effectiveness. For routine work on ground targets, a more promising solution seems to be the use of UAVs of the Grom type, developed by the Kronstadt company..

It seems more expedient to use the S-70 Okhotnik UAV with complex and effective high-precision munitions to hit especially important targets. However, it is worth making a reservation here - even the low-visibility S-70 Okhotnik UAV is not invisible and invulnerable to enemy SAMs and air-to-air missiles, while it itself will be a very desirable target for the enemy.
This means that when penetrating enemy airspace, the S-70 Okhotnik UAV can be detected and destroyed by enemy aircraft or anti-aircraft missile systems (SAM) operating in ambush mode. We should not forget about the risks of interception or suppression of the control signal - this problem will be extremely relevant for Russian unmanned aircraft until we have our own high-speed encrypted satellite communications.

According to unconfirmed reports, the remains of the S-70 Okhotnik UAV lost in Ukraine
As for the use of the S-70 Okhotnik UAV as a “faithful wingman” for the Su-57, there are also a number of questions here.
For example, the Su-57 fighter is capable of moving at supersonic cruising speed without using afterburners, while the S-70 Okhotnik UAV is, by all indications, a purely subsonic machine, meaning that when working in a group, the speed of the group will be limited by the capabilities of the slower machine.
There is also a question about the onboard radio-electronic equipment (avionics) of the S-70 Okhotnik UAV, primarily the radar. Of course, if the said UAV is equipped with a modern, highly effective radar, for example, based on the Belka radar of the Su-57 fighter with an active phased antenna array (AFAR), then the range of tasks solved by the S-70 Okhotnik UAV will increase significantly, but the cost of such a machine will also be high - the cost of a modern radar/avionics can be a third, or even half, of the cost of the entire combat vehicle.
Thus, it can be assumed that the joint use of the Su-57 and the S-70 Okhotnik UAV will be optimal and effective for missions to destroy especially important targets at a great distance from their bases, when the Su-57 in a group with the S-70 Okhotnik UAV will move at subsonic speeds, and the increased risk of losing the expensive S-70 Okhotnik UAV will be justified. In other cases, for example, for jamming or delivering additional ammunition in the LBS area, it is more practical to use the cheaper and simpler Grom UAV.
It is also worth remembering that the Su-57 is a single-seat combat aircraft. Will the pilot be able to simultaneously control his aircraft and the S-70 UAV? For the two-seat version of the Su-57, such a combination looks much more logical, but so far there is no reliable information about the creation of a two-seat version of the Su-57 and the order of such machines for the Russian Aerospace Forces.
We previously discussed these issues in the article “Hunter” is approaching: prospects for the use of the heavy stealthy S-70 UAV in Ukraine.
Conclusions
Based on the above, we can state with a high degree of confidence that the heavy UAV S-70 Okhotnik may enter serial production in the near future.
The operation of the S-70 Okhotnik UAV over enemy territory will be limited due to the high risk of losing these vehicles both from enemy air defense systems and fighter aircraft, and from the possibility of intercepting or jamming control channels.
On the combat contact line, to perform routine tasks such as dropping aerial bombs from the UMPK, a more promising solution seems to be the use of inexpensive Grom UAVs with simple avionics, which should be produced in large quantities.
As a “faithful wingman,” the use of the S-70 Okhotnik UAV will only be appropriate for a limited number of missions to destroy particularly important targets at a great distance from the base, taking into account the high risks of losing the latest combat vehicles and them falling into enemy hands.
As a "faithful follower" - a carrier of funds EW, anti-radar missiles (ARM) or air-to-air missiles, the optimal solution will most likely be the same Grom UAVs, especially in the stealthy configuration in which this UAV was originally planned to be created.
Thus, we can potentially consider the possibility of using the S-70 Okhotnik UAV as an aviation platform for the creation of a promising spatially and functionally distributed AWACS complex.
We will talk about the prospects and advantages of this solution in the next article.
