Karrar is either a reversed engineer T90 that Iran got her hands on in Syria , they some how got the blue prints , or the Russians gave Iran the blueprints in some back door deal.

Production version of the Karrar MBT unveiled (updated)

The new main battle tank (MBT) of the Iranian armed forces has finally been revealed to the public in March 2017. The original tank revealed as the so-called "Karrar" was an upgraded version of the T-72S Shilden, the last Soviet export version of the T-72 main battle tank.

T-72 being upgraded to Karrar

The Karrar is inspired by the latest Russian T-90MS tank, an enhanced version of the T-90. Unfortunately finding detailed information in English about Iranian tanks is rather problematic, so that the exact relationship between the T-90MS and the Karrar remains uncertain. According to Iranian news websites, the army tested the T-90S or T-90MS in or before 2015, but penultimately rejected buying the tank in favour for a local alternative. This lead to the development of the Karrar, but it is not entirely clear if it is meant to be a copy of the T-90MS or the similarities between the two tanks are result of the a cooperation with the Russian industry. Both versions have been mentioned in different forums and blogs.

The Karrar features a new welded turret

The Karrar tank is still an upgraded T-72S, but it is fitted with a completely new, welded turret as newly released video footages shows. It is also fitted with digital control panels and a battlefield management system. The base armor package of the Karrar's turret was improved, offering a higher level of protection compared to the older composite armor in the cast T-72S turret.

The Karrar provides digital control panels for the crew

Compared to the T-72S Shilden, the current MBT of the Iranian Army, the Karrar offers improvments to armor protection, firepower and electronics. There is no indication that the engine was altered, so the mobility appears to be equal to that of the original T-72S, maybe a bit worse as result of the weight increase.

Not the extruding steel casing at the gun mount

The tank features a new polygonal metal sleeve at the base of the gun barrel. The purpose of this design has not been revealed yet, but it might be an attempt to reduce oscillations when firing on the move. On some combat vehicles, such as the German Puma infantry fighting vehicle (IFV) and the Ukranian BTR-4, the gun barrel is enclosed in a metal casing in order to provide better stabilization when firing multiple rounds on the move.

Karrar MBT prototype: new armor is colored black, while the vehicle is painted grey

The armor protection has been improved by fitting a more modern ERA package to the tank. Previoulsy the T-72S was fitted with the Soviet-made Kontakt-1 armor. The new explosive reactive armor (ERA) covers the frontal aspects of turret and hull, while also protection the hull sides along the crew compartment. At the engine compartment and turret rear section, slat armor is utilized for protection against rocket-propelled grenades (RPGs). The turret sides are fitted with spaced composite armor modules.
837279_304.jpg

Note the odd shaped ERA the glacis, LED headlights, driver's optics and the new gunner's sight

While the explosive reactive armor at the turret front and hull sides appears to be very similar to the Relikt ERA solution used on the T-90MS, the ERA package mounted at the glacis uses oddly-shaped ERA tiles, that are very thick, but have a rather small overall size. It is about twice as thick as the normal Kontakt-1 ERA used on the T-72S Shilden. This type of armor is somewhat reminiscent to the ERA used on Iranian M60 tank.

Most likely the reactive armor of the Karrar provides protection against RPGs, anti-tank guided missiles (ATGMs) with single-stage shaped charge warhead, as well as some degree of reduction in the penetration capabilities of APFSDS ammunition. It might also provide some limited protection against tandem shaped charge warheads, but that is not confirmed.

The T-90MS features ERA also at the turret sides

It must be noted that the latest version of the T-90MS also features explosive reactive armor covering the spaced side armor modules of the turret. On the Karrar such armor is not found, suggesting that it might be reverse-engineered by the Iranian military industry based on older photographs of the tank instead of being a proper cooperation between Iran and Russia. Alternatively Russia might have only offered the older version of the tank, which lacked the enhanced side protection. Two banks of six smoke grenade launchers allow the tank to hide while retreating.

RWS and coommander's sight of the Karrar MBT

The Karrar is fitted with a remote weapon station (RWS), which is coupled to an independent optic for the commander. It includes a thermal imager, a day sight optic (probably a CCD camera with zoom functionality) and a laser rangefinder. The weapon station is armed with a 7.62 mm machine gun and also includes a secondary camera located left to the armament.
This RWS desgin is also used on the T-90MS and on some products of the German company Rheinmetall, where it is known as main sensor slaved armament (MSSA), consisting of a heavy machine gun and a SEOSS sight.
837791_938.jpg

Prototype fitted with the older generation RWS

Older photographs show the Karrar being fitted with a different RWS, which usually is armed with a Soviet-designed PKT machine gun, but it seems to lack the same advanced optronics of the newer design. This remote weapon station is also a lot more bulky, because the ammunition container is located at the side of the gun.

The Karrar MBT features an upgraded fire control system

The fire control system (FCS) of the Karrar has been significantly enhanced. Aside of the new indepent sight for the tank's commander, the main optics for the gunner have been replaced. The gunner's sight now features not only a day sight, but also a thermal imager for enhanced target detection and acquistion at night and in situations with reduced visbility. The origin of the new FCS is unknown, but the local industry has utilized the EFCS-3 from the Solvenian company Fotona in the past to upgrade the dated M60A1 and T-54 tanks. The Defense Industries Organization (DIOMIL) of Iran also offered the KAT-72 FCS as upgrade for older generations of T-72 tanks. Both these systems however lack thermal imagers and independent sights for the tank commander, suggesting that the Karrar utilizes a newly developed system - probably incorporating imported technology. Iran has been supporting the Syrian government, which operates T-72 tanks fitted with the advanced Italian TURMS system. Iran also has good relations with North Korea, from which Syria imported components of thermal imagers for upgrading older T-55 tanks.
A small searchlight, which probably can be rotated, is located next the gunner's hatch. The driver is provided with a new camera system next to his vision block, which contains two optics - probably a daysight CCD camera and a night vision optic. The tank also features new LED headlights.

Suprisingly the Karrar appears to be one of the most advanced modernizations of the T-72 tank, albeit the performance and specifications of most components are currently unknown. If the engine was replaced - but there currently is no sources suggesting that this happned - the tank could be even better. It might be able it compare favourable to tanks such as the Russian T-72B3 and the Polish PT-91 Twardy in many aspects (such armor protection and firepower) - but in the end the crew performances matters just as much as the equipment.

Some pro and contra:

Pro

- The compact design of the T-72/90/Karrar keeps it under 50T hence less material used and less cost.


- The compact design allows it to concentrate more armor at the critical fronts. at 10-20 tons lighter weight it can reach equal protection levels as western designs and higher.


- The compact and geometric design makes it less exposed than western tanks such a M1/Leo2, especially at the sides of angled turret up to 30° off-boresight (realistic battlefield flanking conditions). Typical western design already expose weakpoints of critical areas at <10°.


- It has one less crewmember than western tanks. For 3 western tanks you can crew 4 Karrars. Autoloader need no training and makes no errors.


- Compared to western tanks like Leo2/Challenger 2 its ammo is inside the well protected hull sealed inside a carousel as well as spare rounds inside the turret bustle, isolated from the crew. It’s possible that extra rounds are stored outside the carousel inside the hull. All of these solutions are worse than the M1 design, but if spare rounds are not stored inside the hull like T-72/T-90/T-55/Leo2/Challenger 2, the chances of a penetration into the carousel (positioned at the bottom of the hull where a hit is least likely) are reduced.

- A high performance TI sight for gunner identification and engagement and a less powerful but flexible commanders sight for target detection. This offers hunter-killer capability as well as system redundancy. It has two axis freedom/stabilization which enables it to employ a laser range finder to get better more information during detection.

- Barrel shroud could improve thermal signature management in the heat of a battle.

- Side and hence off boresight protection due to ERA is only rivaled by lastest "urban warfare" western tank designs.

- Typical for later T- tanks it has a laser beam riding barrel launched missile which is effective to extended ranges of 4km and even useful against helicopters.

contra

- APFSDS ammo needs to be on pair and of high performance for anti-tank performance against modern tanks. Irans shown ammo are short rod penetrators. Autoloader would need to be modified to accept long rod penetrators if available. The 125mm gun version given to Iran is not the lastest high pressure variant and hence would have lower penetration performance. No muzzle reference system as on modern western designs and T-90MS (good for long range engagements).

- Iranian armor technology and ERA development are unknown, hence performance could be lower. The T-72B turret armour is the same as Iranian T-72S and had very good performance against KE threats in the 80's) Against new threats the hull armor, beside ERA needs to be improved as well because it protects the carousel with the ammo.

- If Iran managed to copy the Soviet 840HP engine it would be a huge achievement. As the Karrar is probably up to 5 tons heavier than the T-72S its power to weight ratio would not be on pair with modern tanks. Help on engines via Ukrain or Belarus could be possible to have something in >1000HP range. Probably Russian made 840HP engines are used for now, until a Iranian engine is ready.

- Crew survivability remains below that of the M1 and T-14 as ammo or crew are not in isolated compartments. However costs and size would rise steeply if such a design would be required. If ammo is only stored in the carousel and turret bustle, ammo ignition and catastrophic loose are relatively unlikely, especially if hull front armor is improved.
 
How does a few welding and a paint job make this tank an Iranian one?! The lies, oh the lies.
Several pages of discussion went right through you. You clearly know little to nothing about tank technology. There are many significant differences between this tank and the T-72s that Iran got in the 1990s.

Say all you want... be as facetious as you want, the truth remains the same: Once again IRI is taking credit where credit is not due.

OK, we have an in-house tank expert here, lets play a game of spot the difference.

Ran out of fingers yet?

Give up. You know nothing about this subject. All you want to do is bash the IR. You are nothing but a troll in this thread.
