Russian defence against drone swarms

Which carrier based fighter aircraft has a radius of 1,000km? wrote:

Each drone could carry hundreds of grenades and could be bigger and faster than these tiny drones and could fly in their own swarms of hundreds of craft individually hunting Russian airspace for drones to shoot down... it could take high res video of the target and the kill and the location so a ground unit could be sent out to recover the pieces and determine if there is a UXO danger and also determine who was attacking Russian territory.

It could be very cheap as those grenades would be very cheap to develop as on firing it could ignite a short fuse like in a hand grenade to detonate the round automatically at a fixed distance from the gun muzzle. If you wanted to get smart you could have a rotary counter on each grenade so you could set the time fuse time so you could set it to explode at any distance you like before firing it though you would probably be better off with an induction coil around the muzzle that automatically sets an electronic fuse on firing the weapon. Simply lase the target and a fairly basic ballistics computer could calculate the time of flight of the grenade to the target... minus 5-10 metres and then work out the flight time and pulse that code to the grenade as it leaves the muzzle on its way to the target...

F-18 Super Hornet is near radius of 1000km. Cirkon is still  develop.

They are also adding to their satellite network too, but really the only carriers that matter are the ones within striking distance of Russia... which puts them well within range of ground based OTH radar and sensor equipment... aircraft carriers have no where to hide. wrote:

Russia needs a new global satellite system for ship detection. Legenda successor. Without it, it will be difficult to shoot targets beyond the horizon at 1000km. There is currently no successor to the Legend system.

nty. Liana will enable them to track carriers anywhere on the planet when it is fully operational wrote:

But now Russia has only 3 satellites of this type? What coverage does it give? Is the OTH radar able to give accurate indications for anti-ship missiles?

They need to control norther sea and pacific sea against Us carriers. Few satelittes, some OTH radars, SOSUS detectors around their coast and maritim patrol planes is enough.

OTH radars have horrible accuracy I think. But you can know if something is coming by and send your air force to investigate.

Some promising Russian means of fighting unmanned aerial vehicles

According to a vector issued by JSC Research Institute Vektor (part of the Vega Concern of the holding Roselektronika), the company took part in the VII All-Russian Scientific and Practical Conference Russian Technologies of Anti-Terrorism Protection, Security and Defense, which is held in Kaluga potentially dangerous objects. "

At the venue of the event, the Scientific Research Institute “Vector” presents the key developments of the enterprise in the field of monitoring the environment of critical objects in order to identify unauthorized UAVs and counteract them - passive coherent location complex (PCL), Cheremukha control channel detection module and small UAV radio-electronic suppression module “ Sickle".

PKL provides the location and tracking of UAVs in a guarded zone, and also controls the drone's movement path when it is suppressed. At the same time, the product uses third-party sources of radio signals to illuminate the targets and is a passive system that does not emit unmasking signals.

The “Bird cherry” module provides the ability to detect, direction finding and positioning both the drone itself and its control panel, while having the ability to simultaneously operate on several UAVs.

The “Sickle” electronic suppression module provides suppression of small UAVs in the angle sector ± 45º and at a distance of up to 20 km, providing continuous frequency overlap in the range from 400 to 6200 MG, currently used for UAV control, as well as all frequencies of global navigation satellite systems. The module creates interference, aimed in frequency and direction, upon command from detection and radio monitoring equipment. An arbitrary number of suppression modules can be included in the counteraction system, thereby solving the tasks of protecting against UAV flying from several directions at the same time, and protecting extended and area objects.

“All the described modules can be combined into a single complex that solves the problem of protection against UAVs. A specific solution - the choice of modification, the determination of the required number of modules, their distribution over the territory of the protected facility, the allocation of each module of its area of ​​responsibility - is made at the stage of project development according to customer requirements, taking into account the configuration of the facility and the threat model. At the same time, the undoubted advantages of our system are the ability to ensure stealth of use, detection of stealth objects, the absence of interference with other radio engineering devices, and the need to obtain permission to use radio frequency channels, ”said Sergey Skorykh, Director General of Research Institute Vektor.

Russians use UAVs with a UHF receiver and optical camera to locate and jam Ukrainian counter-artillery radars, then call in mortar strike on radar location. In 2019, two Ukrainian UAV jammers were shelled using this method but they survived.
