Keep it on Arjun, discuss your personal vandetta somewhere else.

The AT in LAHAT stands for Anti Tank.

LAser Homing ATtack Missile, or LAHAT, is an advanced missile developed and manufactured by the MBT Division of Israel Aerospace Industries (IAI). It is a light weight missile suitable for precision attack missions

really??

High Explosive Anti Tank rounds are used at long ranges against conventional steel or rolled homogenous armour but their effect is questionable against relatively thick armour. They are useless against a composite layered armour.

The missile uses a tandem warhead which is capable of defeating all types of modern armour, including add-on reactive armour. High penetration capability of the main warhead allows the missile to penetrate the armour of major armoured vehicles at high impact angles.

Modern anti-tank missiles such as AGM-114R, Spike, Javelin and TOW provide armed forces with the capability to stop a heavily armoured tank in its tracks

Spike missiles are fitted with tandem-charge high-explosive, anti-tank (HEAT) warhead

Javelin is considered the world's best shoulder fired anti-tank weapon. It carries a tandem shaped charge enabling a maximum range of 2,500m.

The PARS 3 LR missile can carry a tandem shaped-charge warhead covering a range of 7km.

Kornet EM is an anti-tank guided missile fitted with a tandem HEAT warhead to penetrate 1,100mm to 1,300mm of armour.

The high-performance armour piercing warhead ensures the LAHAT can penetrate even add-on reactive armour.

The MILAN ER is fitted with a tandem charge warhead to neutralise new generation explosive reactive armour used by some main battle tanks.

The single shape charge warhead of the NLAW has been designed to defeat modern MBTs fitted with ERA.

The world’s deadliest anti-tank missiles - Army Technology

The 9M119 Svir and 9M119M Refleks are laser beam riding, guided anti-tank missiles developed in the former Soviet Union Both are designed to be fired from smooth bore 125 mm tank and anti-tank guns The tandem warhead can penetrate up to 900mm of armor (35.4 inches).[.

If HEAT rounds are so useless, why are we still seeing to many of them? Why are they still in the newest of anti-armour missiles?

If HEAT rounds are so useless, why are we still seeing to many of them? Why are they still in the newest of anti-armour missiles?

they are not useless, but they are not aimed specifically for anti tank role. For example, a apfsds penetrator has its limitations in range, usual range varies between 1.5-2.5 or 3 km in some cases at best. a atgm usually has longer engagement range so it mightwork beyond 3km. Regarding tandem warhead, it depends what threat is it used against. a high quality composite armour such as burlington was aimed to take multiple hits from all threats, more so from heat rounds.

In essence, modern composite armour modules based on multiple layers with different materials is a hard nut to crack for any heat round, be it a tandem or single warhead.

There are few if any APFSDS rounds for use by infrantry. Hence, most RPG ad ATGWs use a heat warhead, some with precursor charge.

Tank gun fired ATGW tend to be inferior to infantry ATGWs due to the limitation the barrel poses on missile and warhead diameter, and hence penetration. Javelin is 127mm. Kornet and TOW missiles for example have 152mm diameter, Spike 170mm, Hellfire 178mm. Lahat can be no more than 120mm. AT11 no more than 125mm.

Missiles that use tandem charges include the BGM-71 TOW, FGM-148 Javelin, Brimstone and the MBT LAW.

Wich ApFsds round being used by our Arjun MBT's??? What is the penatration power of that round???

not sufficient to penetrate composite armour..

The Rheinmetall DM33 for the LEO2's 120L44 has a three-part aluminum sabot and a two-part tungsten penetrator, and is said to be able to penetrate 560 millimetres (22 in) of steel armor at a range of 2,000 meters (2,200 yd).

To one question the writer also answered. "New 120mm & 125mm APFSDS rounds with 600mm RHA penetration capability is now in an advanced stage of development. 125mm APFSDS round with 500mm RHA penetration capability is already under bulk production."

arjun cant fire them, 125mm ammo

dm33 is obsolete intodays battlefield

dm33 is obsolete into days battlefield

Where did I says it was the most modern? I posted for purpose of comparison of penetration at same range. What is the problem?

One of the most prestigious and ambitious weapon system project undertaken at ARDE is the 120mm Main Armament and Ammunition system for the ARJUN MBT. This is a high-technology program involving a number of disciplines. ARDE has developed a super velocity gun and a family of ammunition with FSAPDS as the primary kinetic energy kill mechanism. It can be confidently stated that the fire power of ARJUN would be comparable with the contemporary MBTs available in the world. It may be noted that only four gun systems in this performance class have been developed abroad namely in UK, Federal Republic of Germany, France and Russia. Even the US and Japan have opted to adopt and licence produce the German 120mm Rheinmetall gun. Our Scientists and engineers, therefore, are justifiably proud to have joined this exclusive `club" with totally indigenous technology. The armament and ammunition system are under current production at OFB.

DRDO

arjun cant fire them, 125mm ammo

Please read the bold part again, it clearly says new 120mm APFSDS rounds with 600mm RHA penetration capability is now in an advanced stage of development.

Why DRDO adopted 120mm Rheinmetall gun for Arjun?

it is Yet to be developed, tested and deployed, which means it is notin service, which means Arjun cant fire an underdevelopment round. Hope you got it.

Where did I says it was the most modern? I posted for purpose of comparison of penetration at same range. What is the problem?

i fail to grasp the comparison, if it was in service with Arjun, if it could be fired with a rifled gun, it would make sense.

They didn't adopt a Rheinmetall smoothbore 120mm. They developed their own 120mm rifled gun.

Does it mean that T72's ammo have more penetration than this T-1?

What does the highlighted part mean? Isn't it related to penetration.
