Main Battle Tanks and Armour Technology

[darklabor]

Yup, you are right. It is curious turret design I must say.

Two-men turret concept.
The intention is to reduce the frontal surface, without loosing gun depression.
Basically the central part of the turret is a regular turret height. Since there is no tandem positionning, the two guys are set lower (gunner a little more than the commander), their roofs are lowered and so their frontal armor follows.

It's a compromise between a conventionnal turret and a fully super structural armement.

I have a question about Relikt ERA:
How does it against tandem charge HEAT?

Check this topis since scirca 194 page
Or find lindsky posts when he is claiming that relikt casette on T-72/T-90 roof is able to ptect against Javelin or Spike warhed.

More or less - Relikt have comfirmed some abilities to be anti-tandem SC warhed protection. But all is depend angle of hit, protected area, and type of warhed.
IMHO it's unable to protect tank roof against diving double SC ATGM (Spike, Javelin).

Live fire testing validates APS maturity for combat vehicle protection

MCKINNEY, Texas, Jan. 9, 2013 /PRNewswire/ -- As the U.S. Army prepares for formal testing to evaluate a system to protect combat vehicles from shoulder-fired and tube-launched Rocket Propelled Grenades (RPGs), Raytheon Company's (NYSE: RTN) Quick Killâ„¢ Active Protection System (APS) has again shown its maturity and accuracy in a series of tests.

In a recent test, held in December 2012, the Quick Kill APS demonstrated its protective capability by successfully defeating an extended set of threats, including one of the most lethal RPG threats by destroying it in mid-flight. All testing is in preparation for formal government evaluations in early 2013 to demonstrate the system's unique RPG-defeat capabilities.

"Raytheon's APS is based on the same radar technology deployed to perform sense and warn operations at active Forward Operating Bases. It has been extremely successful in providing timely warning against rocket and mortar attacks," said Jeff Miller, vice president of Combat and Sensing Systems for Raytheon's Network Centric Systems business.

"With Quick Kill," he added, "Raytheon has matured a highly advanced system, offering our forces an unprecedented force protection capability that is essential to the future survivability of combat vehicles. This technology is ready and could begin fielding within a year."

The Quick Kill system consists of a multi-mission, fire-control radar that detects and tracks incoming threats, combined with hard-kill countermeasures that serve as a hit avoidance system, enabling multi-tracking and multi-engagement of enemy fire for vehicle and squad protection.

The system's vertical launch countermeasure is unique in its ability to engage threats fired from any angle or elevation, providing all weather, full 360 degree hemispherical vehicle and crew protection with each countermeasure.

In previous tests, the system demonstrated its ability to defeat multiple threat types both from a stationary and an on-the-move platform – and it showed its multi-threat capability by defeating two simultaneous threats.

Seems that Quick Kill is not "dead" and there is progress in development, good news.

All Armour and ERA depends on Hit angle ,protected area and type of warhead for its effectiveness and Relikt is no difference.

Top Attack exploits the weak area in tank defence and Relkt would just make tandem warhead job more difficult exploiting that weak area due to its anti-tandem properties , the best protection against top attack is Active Protection System with ERA like Relikt to make it that much harder.

A new "eye" for the Leopard

M1A1FEP used by USMC after modernization, new SCWS (Stabilized Commander Weapon Station) cupola clearly visible.

 

[STGN]

Just to clarify the SCWS is really more of a upgraded CWS than something entirely new. The old CWS has have its manual MG rotor replaced by a electric stabilised rotor and a armoured shield for the commander bolted on top of the CWS.
STGN

 

[Damian]

I do not think that this is simple modernization, whole machine gun mount had been replaced, sights also are new (day + thermal), also I still don't know how it looks like from the interior point of view.

Of course it uses elements from the CWS, but many were replaced and of course new elements were added. Interesting design I must say.

 

[Damian]

And some more.

INDIAN EXPRESS: Interview with Oleg V. Sienko, CEO, Uralvagonzavod

"Modernized T-90S tank is the next step in development of Russian tank- building"

Some specs of Armata Project reveled link

"By the year 2015 the "Armata" project will be completed. It's not an armored fighting vehicle in the conventional sense, but rather a cutting edge multipurpose base for infantry fighting vehicles, accident rescue vehicles and others. They will have a modular system and repairing them will take very little time and effort even in field conditions. The damaged item will be easily removed and replaced," he said.

Nice! A very rare version of M4 Sherman.

.

This is a really good protection for the commander handling the HMG and imho its much better than any remote controlled device.
Wish we came with something like this on our MBT but I believe our top brass doesn't believe we shall be engaging urban combat rather all out war.

 

[STGN]

That is just so the commander can stick his head out and look around in relatively safety from snipers he is gonna be down inside the turret when he fires the gun just like the old CWS. While its great for urban combat it does make the tank rather tall and easier to see at distance in open terrain. But looking at the M1A2 SEP V2 its not something the Americans really worry about.
STGN

 

[Damian]

Protection on SCWS is jut bolted to the cupola, if nececary it can be deinstalled. Every part of up armor kits recently added to M1's were designed as fully modular, so every part can be installed, or only some specific ones.

 

[STGN]

Off cause anything mounted can be demounted. Was merely thinking about when it is mounted. Though looking at the A2 and the CROWS making the tank low seems not to be a top priority at the moment?
STGN

 

[Damian]

CROWS is high when in combat position, it can be lowered to stowed position. However photos of such are rare.

Also CROWS acts like a second CITV, it is fully connected to TC controls, do not require separate display anymore, uses CITV display. However I do not know th extend of connection, if it is only partial or complete to the vehicle FCS.

CROWS definetely improves situatioal awareness, it is extremely fast when it comes to rotate 360 degrees and in elevation, and optics are not worse of these in CITV and GPS (Gunner Primary Sight).

Although yeah, it seems that overall height of vehicle is not considered as a problem. However it is planned to install additional RWS for loader as well. It will be modified machine gun mount currently used, smart idea, and does not need any deeper modifications.



Here you can see a folding mechanism and storage rest on turret roof. So CROWS folds to the side and then it have only slightly more height than CITV.

 

[Damian]

Here folding mechanism and storage rest for CROWS are better visible.

And here better photos of folding mechanism.

And USMC M1A1's are scheduled to receive reometely controlled ILWS (Improved Loaders Weapon Station).

 

[JBH22]

I have 1question regarding anti tank rocket launchers why would one use a one shot launcher (RPG-30) instead of a reusable rocket launcher (RPG-29).

Both of the rocket launchers mentioned above are considered to be in the heavyweights in Indian army they use SHIPON,RPG-7 and Carl Gustav which are essentially medium if not light rockets. In foreign armies do they have heavy anti-tank teams distributed across regiments/battalions if yes then how and which numbers?
