As weapons evolve tactics evolves with it.
I don't know about guided missiles but anti personnel canisters and /or high explosive shells can be handed on to other mobile artillery mechanism as tanks sheds their most heavy armor to obtain better mobility. I believe rain guns are also considering a shot gun type shells.

Specialist tanks was tried before back in WW2 with Infantry support tanks and the like it never really worked. Sure there are other platforms, Mortar vehicles, IFVs but tanks need to be able to multi role. If a rail gun can fire a canaster round "Shotgun" shell as you put it then a HE or other round could be worked but fist it has to be proven.
I to do believe that future tanks will get lighter but there are still going to be other threats necessitating at least a medium armor size. Anything under 30 tons is going to start having issues as infantry and infantry weapons as well as other armored vehicles with conventional and advanced weapons are here to stay. As to will there be means and methods developed to try and counter Railgun and advanced penetrators. What? You got me but for every advance in offence there is always a push ahead in defense. Perhaps the electronic armor system that the British were looking into.

Not every nation is going to adopt lighter tanks some are going to feel the need to maintain heavier tanks the Altay and K2 for example. South Korea feels the need of heavy MBT's as North Korea has something like 3-4x the number of MBT's mind you the North Korean MBT's are dated at best primarily T55's, Type 59's, T62's, T62 clones and A T62/T72/T90 hybrid but numbers count for something.

I certainly do see the reason for SK or Israel not needing a deployable tank. The ability to survive multiple hits, just because there's so many OPFOR, is their prime concern. I wonder if some kind of "smart armor" innovation is viable. If a tank is hit and the ERA plate in that space is expanded, may the tank can rearange the ERA plates mounted on the hull via a appropriate mechanism. ..


2) RPG's are common but dated more and more ATGM's are moving to the fore front, Look at Syria and Iraq where Groups whether AQ, ISIS,other islamist and non-islamist are widely using ATGM's widely. and many are top attack which is unprotected by ERA or Slat.
[...]
another feature that seems to be coming into vogue is remote or Unmanned Turrets. This offers a nice option for a number of reasons. by making the Turret unmanned in the event of a top attack ATGM the Turret my be disabled but the Crew is in the Hull this means you only really have to focus on armoring the hull as that's where all the most valuable mission needs are. The Human crew.

Then again, if the turret becomes unmaned, it could at least partly be ERAed or caged, I suppose.

I'm also wondering if a front mounted engine provides benefits for other designes as well. That would require a far back mounted turret to allow the drive space to see via non optronic means. And while it may provide additional protection from the front, any hit there will right away immobilize the tank.

Mounting the Turret to the rear has better recoil characteristics. That's why most tracked SPH do it. I favor the Hybrid drive as you can mount your engine just about anywhere on the vehicle and use smaller engines. Dual mounted small engines placed above the rear portion of the track opens a space in the rear for the crew to egress as the turret would lack hatches if its unmanned. Additionally could allow easier loading of the magazine via a hatch mounted between the hull and turret and repair of the engines from the interior of the vehicle.
Adding era tiles to the top of a unmanned turret sounds more reasonable then Slat. Although Slat would likely be mounted around the tanks optics.

Within the next decade we will be seeing rail gun technology adopted into main guns of MTB since the gas turbine generators can generate more than sufficient amount of electricity to power the guns.
With these guns armor will become less relevant since no matter how thick you make them the rail guns will rip right through it.

Railgun is governed by electric storage, which improves very little over time. The electric energy density of current tech is very low compare to explosive or gasoline (two orders of magnitude lower).

Here are some maths: 10MJ muzzle energy for a normal gun, accelerated in under 10ms, so power requirement is at least 1000MW. Power density of ultracapacitor is 15kW/kg, now, calculate the weight of storage device: 67 tonnes. That is not counting the efficiency of the system, and the storage requires for future gun tank could easily reach several hundred tonnes.

Even if somehow magic happens in electric storage device (which is unlikely), the problem of penetrating armor is not power alone. Most modern armor uses some kind of active armor (even the so called passive armor), which the armor attacks the penetrator, e.g. from side. And the penetrator must survive the attack to penetrate armor. The faster the penetrator goes, the higher the impact is, and the harder it is for surviving the attack of the armor.

That is not counting other type of APS that can destroy penetrator before it contacts armor. You guys here seem know very little on the advancement of the armor tech.

The reason why the Navy is investing in new technology like EMAL, rail guns and/or high power lasers which requires high energy density storage is because of the technological break through that are being made.
As for active armors there weakness is they can't withstand constant hits and their limit is there chemical reactions so a faster incoming perpetrator than the active armor can react makes the active armor useless.

Re: Russian military news thread

No bar it can't. Abrams uses a compartmentalized ammunition system. The only ammo in the crew compartment is being loaded into the breach otherwise the ammo magazine is only open to the crew compartments when the doors are open and the loader is grabbing a round and a set of guillotine doors separate the the two compartments the doors are only open for about a second when the loader places weight on the leaver the enemy would have to strike at that exact time. Otherwise the Blow off panels would prevent the spread the explosive force. If a Opfor tank hit the ammo which is in a magazine located in the back of the turret. The crew compartment and the turret ring would remain intact.
For what ever reason you choose to claim, the fact is in combat the T72 failed and failed spectacularly against western tanks and ATGMs including turret separation.
. T90 was meant to correct this with APS and improvements in armor for the intermediate period until the next great Russian tank design which was to be T14 armada which would have featured a totally unmanned turret. Isolating the crew from the Ammo and upping the protection, this hull would also be the basis for heavy IFVs, howitzers and other platforms and have a weight of 55 tons.

Which never happened in real life.

There was no single western tank that ever has engaged against Ural T-72's - offensive language removed -, Iraqis downgraded RHA steel or Asad Babils that were not even made on WW2 standards due embargoes, as an accomplishment or for any argueing reasons. The T-72 and the capsuled autoloader are all around safer than any western tank.

Bar is right the real problem is the ammunition stored in the turret around the crew which is exposed and the ammunition is made of a Paper like material that vaporizes in the barrel when the the ammunition is fired, this material catches fire fairly easily, that is also the reason why all fuel is external on russian tanks and not internal to decrease creatley the fluids of oil and diesel that can overtime leak through and would cover the floor,walls and what not inside a tank which is the case and a bad thing that is known to plague the Abrams.

The bustles on Abrams like on any other tank are not armored and can be penetrated by almost any weapon bigger than 14.5mm. The tank is even frontally very vulnureable, when the Gunner looks around with the Turret the ammunition bustles are exposed from the front and that is a combat relevant "tank kill".

If the enemy shoots and hits the ammunition bustle in this position from the frontal sphere that is a "kill", the crew probably survives but the tank is gone and that is the only thing the enemy needs to achieve, to destruct the enemies armored capabilities and obliterate the danger.

Ammunition bustle is also not a garante for crew protection but it increases it still. If the under any situation urban warfare or anythign similiar the ammunition bustle is penetrated by a RPG from behind and the jet stream punshes a hole through ammunition bustle and the backside of the poorly armored turret there is a direct entrance for the exploding and burning ammunition right into the loaders crew space and following the physical principle of "Path of least Resistance" the burning ammunition will search for a direct path with the least resistance. The flames will be definatley bigger through the blow out panels because they are bigger but the loader will still be roasted. Slim and very specific situation i descrip but not impossible.

Black Shark, watch your language on SD Forum.

READ THE RULES.

Also, I would advise dialing down the emotion and pointed verbosity a few notches.

I consider the Abrams to be a better design than the T-72/T-90. But that doesn't change the fact that the carousel system is better for protection than the separated compartment system on the Abrams.

In the Abrams, if the ammo compartment is hit, it is over for the tank as a fighting force. In the T-90, unless the shell penetrates and kill or injures the crew, the tank is still a fighting force. The probability of hitting the ammo in the carousel is extremely low compared to hitting the back of the turret. And the ammo cooking off in the separated compartment doesn't mean the crew could be safe.

If we only talk about the Abrams, then it is true that it is a better protected tank than every other tank out there, but if we classify all the western tanks as being better protected, then that is wrong. For eg: The Leo2 carries only 15 protected shells, the rest are not protected. The Challenger 2 has no protected shells, the same as the Merkava Mk4. Leclerc too has 18 unprotected shells. Point being I wasn't referring to the Abrams in particular. I just pointed out that even the Abrams can have its turret blow up if the ammo is sticking out.

The turret of their Challenger is reported to have been blown off in the attack, which happened in pitch darkness.

This was blue on blue, but the result was the same as the T-72.

As for the T-72, it did not fail. What failed was Iraqi armor tactics, training and the fact that the tanks were 20-30 years behind their time compared to the latest in technology for the blue forces. Bring in a M1A1 Gulf War model against a T-90A, even with an equally trained crew rather than the lopsided crews of the Gulf War. The result will be the exact opposite of the Gulf War. The Iraqis fielded very old shells of the post-WW2 vintage which were made of steel. They never had a chance.

The T-72 would never have had its top blown off had the crew not been sitting next to unprotected live ammo. They made that mistake again and again.

BTW, the Obj 195 was 55 tonnes, the Armata family will be less than 50 tonnes.

Absolute pure conjecture.

I have no doubts that the latest Russian tanks vs the latest US tanks would produce different results than the Gulf War absolute slaughter of Iraqi armor (meaning it would be a tough battle with the US taking losses).

However, nonetheless, given the overall advantages in Joint Force fighting experience and tactics, overall battlefield sensory advantages, and advantages in certain western technologies to this day, to say that the results would be the exact opposite of those Gulf Wars (which would mean that the US forces would suffer greater than 100 to 1 losses), is just pure fantasy.
