Indigenous Arjun MBT has Only 42% Indigenous Content

Anything about n "Indigenous", thread is my concern:D, don't you see I am "indigenous myth buster"^TM??


hahaha...carry on ur busting while we happily keep producing those Arjuns. :wave:

And do u know a secret abt Arjun : In war if u stand in front of Arjun and say "Stop firing..ur only 42% indigenous" it will stop firing..
Dont say this secret to any one....:lol:
 
So to recap "Indigenous" Arjun tank

  • Designed by Karuss -west German
  • Tank Gun - Rifled, British
  • Engine -- MTU, German
  • Transmission -- Renk, German
  • Main Gunner Sights-- Assorted, International vendors
  • Tracks --Again German

  • Whats left Machine gun not even that:lol:
  • Armour,-- untested mass of metal.:pop:

Maybe you are right:D, but this thread is not about that:sniper:

By raising un-related topic, you are trolling on this thread.


I hope this is not repeated.

If you still interested about AL-Khalid, open a thread for the same:pdf:
 
How much indigenous components can be used is dependent on the order size. If you have huge orders, you can try to manufacture most of the parts as your investment for building up facilities for those components will be compensated by the large number of units you are manufacturing. But if you have smaller order, you can not try to manufacture each and every components as you wont be able to cover up the cost you have incurred for building facilities for those. It is simple rule of economies of scale and true for almost all nations.

Thanks, But DRDO was tasked with "developing" Arjun.

Talk about manufacturing comes when only systems were already developed, which is not the case.

:rofl: Clear way of ranting!!! dude you don't know ABC of a tank. Ok take this.... Do you know except name there is nothing in Al Khalid that is Pakistan. French and US tanks also have lots of foriegn staffs.

lol Educate yourself.....

Armor :

Kanchan, best in the world, proved in live fire from point blank range.


Kanchan Armour is the name informally given to a modular Composite armour indigeneuosly developed by India. The Kanchan Armour got its name from Kanchan Bagh, Hyderabad, Andhra Pradesh, India where the Defence Metallurgical Research Laboratory (DMRL) is located.

Although the construction details of the armour remain a secret, it has been described as being made by sandwiching composite panels between Rolled homogeneous armour (RHA). The number of layers may vary based on the user requirements. This armour is able to defeat APDS and HEAT rounds and is believed to withstand APFSDS.

120 Millimetre MBT Arjun Armament System

A state-of-the-art weapon and ammunition system has been developed by the DRDO for the Main Battle Tank (MBT) Arjun by adopting novel design concepts and latest technological advancement at par with the industrially advanced countries. The system is capable of destroying modern heavy targets up to a range of 5000 m. All aspects leading to ergonomics, product reliability, maintenance, ease of operation, and futuristic performance enhancement have been incorporated in the design of the system.

The following indigenous technologies have been developed and established during the course of the system development.

*

Electro slag refined (ESR) steel for gun barrels
*

Partial length autofrettaging of gun barrels
*

High pressure packing rings for recoil system
*

Tungsten alloy penetrators
*

Fin stabilised kinetic energy shot
*

Special alloy steel obturating cups for cartridge cases
*

Semi-combustible cartridge case and primer

Armament System

clip.gif (1016 bytes)Gun System

The 120 mm rifled gun for MBT Arjun is made of special steel produced by the latest 120 mm rifled gunESR/Vacuum Arc Remelting process. This has enhanced the performance and fatigue life of the gun barrel. The gun barrel has been partially autofrettaged to a pressure of 800 MPa to achieve a proof pressure of the order of 612 MPa. This is the first indigenously developed gun capable of firing at such a high service pressure achieving muzzle velocity of 1650 m/s and above. Efficient fume extractor of the gun ensures that no toxic fumes are left in the crew compartment. The gun is fitted with FRP Thermal Insulating Jacket to obviate differential thermal effect, thereby enhancing the accuracy of the weapon system.

clip.gif (1016 bytes)Recoil System

The Arjun recoil system is a compact, lightweight, short recoil hydro-spring type, capable Arjun recoil systemof absorbing the thrust of high pressure and high velocity gun. The system consists of two hydro-spring buffers mounted diagonally to meet the stringent space requirement inside the fighting compartment. The innovative design of taper control rod gives uniform recoil and run-out, thereby enhancing the accuracy and life of the system and the high rate of fire. The high pressure and durable packing rings coupled with high surface-finish of mating components ensure longer life and high reliability. This is a sealed system, which requires practically no maintenance.

clip.gif (1016 bytes)Ammunition System

Two types of ammunition, namely, Fin Stabilised Armour Piercing Discarding Sabot (FSAPDS) and High Explosive Squash Head (HESH) have been fully developed and productionised for MBT Arjun.

The complete round of Arjun ammunition system consists of a semi-combustible cartridge case with steel obturating cup, semi-combustible primer, propellant, additive liner for wear reduction of gun and FSAPDS shot/HESH shell. The semi-combustible cartridge case (SCCC) ammunition has the advantage of reduction of round and chamber length, weight of the round, ease of handling, higher muzzle velocity, higher rate of fire, longer barrel life, and logistics.

clip.gif (1016 bytes)Steel Obturating Cup

Steel obturating cupThe SCCC technology is being used in the contemporary tanks. Steel cup is a major component of SCCC technology used for indigenous development of the ammunition for the Arjun tank, and has been designed, developed and productionised by the DRDO for the first time in the country. This component provides effective obturation during firing of the ammunition.



clip.gif (1016 bytes)FSAPDS

FSAPDS is the primary antitank ammunition for Arjun. The complete FSAPDS round consists of fsapds1.JPG (91860 bytes)semi-combustible cartridge case, semi-combustible primer with steel obturating cup, triple-base propellant, and wear-reducing additive liner. The sub-calibre kinetic energy projectile has a very high-density long rod tungsten alloy penetrator enclosed in a three-piece sabot segment and a tail unit for in-flight stability with tracer. The shot is machined to a very high degree of precision with best CNC machines and online inspection to achieve the high standard of accuracy. This hyper velocity ammunition can defeat all the modern targets at a range of 5000 m and above. The accuracy and consistency of the shot is of the order of 0.2 mil standard deviation.

clip.gif (1016 bytes)HESH

hesh1.JPG (84520 bytes)High Explosive Squash Head (HESH) is the secondary ammunition for Arjun and is effective against a variety of soft targets, tanks, fortifications, etc. The complete HESH round consists of a semi-combustible cartridge case, primer with steel obturating cup, and a single-base propellant. The optimised explosive composition of HESH defeats rolled homogenous armour plate detaching a scab of about 9 kg mass moving with a velocity of 100 to 120 m/s. Besides the scabbing effect, blast and shock imparts a tremendous jolt to the enemy tank stripping off explosive reactive armour and incapacitating the crew severely, thereby affecting their fighting capabilities. The accuracy of the HESH is of the order of 0.25 mil standard deviation.



The gun/ammunition system has been fully optimised and integrated with the MBT Arjun, meeting the stringent GSQR for consistency, penetration, lethality and high rate of fire. The production in ordnance factories has been well established. Strict quality control measures in the production stage and the final inspection stage are being maintained by DGQA/SQAE to ensure highest standard of quality.

Developing and more developing since 1973:wave:

Atleast we didn't name a foreign tank with 'indigenous' name! On the other hand much better than anything China can produce.

BTW where did you got the info that the gun is from UK and the armor is of metal? BS, isn't it? Just troll.
:lol:

Indigenous name....?!?!?!

Al Khalid is named after an Arab general Khalid-ibn Walid...Not even that is Pakistani. :lol:

You took my words. Believe me, I was just thinking about that. :lol: They are always ready to talk about Indian systems but why don't they think about themselves? It seems like Pakistanis spends more time thinking about India than the Indian themselves. :rolleyes:

Its like the foreign systems will not fire when there is a Pakistani tank comes in Arjun's sights.

Its earlier posted that how much systems are in Al Khalid from China and Ukraine. How much systems are there in Merkava, Abrams, Lecrec and other tanks from other countries.
