The T-80s future in the Russian Army

The problem with MMW radar is that it can be detected and triangulated.

Some other technology needs to be used like LIDAR.

Holly shit

Drones are very effective, but mobile gun platforms are necessary, so a combination of countermeasures will be applied to keep tanks useful and operational and in fact coordination of tanks using drones to spot ahead actually makes tanks more effective and more powerful.

Pretty soon those FPV will be targeted by active protection or specialized gun turrets. It is just a matter of time.

Lancet is - relatively of course - expensive loitering ammunition.
It is nothing new, has been there for a while.
The difference is that it is an inexpensive sensor that makes it explode from a distance allowing proper activation of the HEAT warhead.
What is dangerous, are dozens of inexpensive toys that can deliver precise punches, because those are so widely spread. You can rip off every subsystem that is not heavily armored. Optics, communication ...
With PG-7 round taped under belly, it can be used for attacking weak spots, ammunition magazine, hydraulics, power units etc.
You can't "explode" ammunition at any distance counting on it will be effective.
5-10 m is not too far for APS, while you can't expect a decent 2-3 kg warhead result from that distance.
There is a precise physical distance for any HEAT warhead combined with its diameter, so you can't just detonate it at a random distance and consider it effective. It won't properly accumulate, or will be already disrupted.

Jamming isn't a final solution because some models have image recognition.

Every drone is different so no single defence system is going to work against all drones, but the Russians are implimenting all sorts of systems and equipment from tank mounted jammers and cages and extra spaced layers of ERA, but also likely optical jammers and of course smoke and they have not finished yet.

There will likely also be EMP directed energy weapons (not lasers) and other systems to deal with drone attacks too, and of course an APS system that can detect an ATGM or tank fired kinetic round should also be able to detect a small drone and "intercept" that as well.

The fight against drones will be ongoing and Russia is getting lots of real experience on both sides of the drone war and appear to be rather good at using them too.

The most dangerous is going to be an AI controlled drone swarm that independently finds and kills enemy soldiers and destroys enemy vehicles and positions... and Russia seems to be getting rather closer to that than any Hollywood movie has managed.

Tanks already have small caliber guns mounted on the turret.   Why not turn these into automated anti-drone units?    The various videos of Lancets hitting Ukr
tanks tell me that a turret mounted gun could take them out.   They do not move all that fast.   FPV drones are not any faster.

Usually the drones are not visible till they are less than 50m away, they normally bob and weave at low altitude out of line of sight of the target till they get close and pop up and dive on the target... they don't need to see the target all the way because the other drone flying much higher that probably found the target in the first place is hovering overhead so the guy with the suicide drone knows exactly where the target is and what cover and protection it has around it so they can fly to gaps in trees and bushes and around any nets set out.

AI controlled drones are going to be far more effective than manually controlled drones because often there is lag in the video display which makes fine manouvering to hit a moving target not so easy... like landing on an aircraft carrier... not easy at all.

Vehicles have APS systems entering service to protect them from missiles and rockets, it just makes sense to extend that protection to include protection from drones as well. I would say a single gun would not be fast enough to be slewed in the direction of an incoming drone which could come from anywhere, so some sort of weapon that has a shotgun like effect that is ready to fire but can be angled slightly before firing for a better hit and wider range of fire including directly up to shoot grenades and light bombs released from above. Relatively light pellet loads would shatter propellers and components to make most drones crash before getting a hit but from directly above you might want heavier buckshot loads to detonate bombs and grenades and larger warheads.

Would love to work at such problems... lots of fun with shotguns and drones and APS systems.

Remember an APS system is already designed to operate with no warning from any angle and to solidly hit fast moving targets hard enough to either set them off or make them crash.

Some sort of directed EMP Weapon might also play a role and of course a dazzling laser or even a laser powerful enough to actually do physical damage might be interesting too... just blinding the optics of the drone and jamming its GPS signals could be part of the solution too, but I think a combination of all of these and rather more will be needed anyway.

Most of the drones we are talking about represent quite a serious threat because of being totally different type of a target.
First, those are very small inn both size and reflection.
Second, emit close to zero heat or EM, especially those that operate autonomously - which will be a standard very soon.
Third, those are almost noiseless.
Fourth, it operates at very low speed.

All of that combined makes it an extremely hard target to detect, lock, and destroy.
What's more, due it's low speed, it will be very difficult to separate them from other objects like birds etc.
It won't be an easy nut to crack folks, that's for sure.

The most serious attempt to make a tank with some serious AD was Slovakian Moderna, with one or two 20 mm Oerlikon cannons.
