Arjun Main Battle Tank series (2 Viewers)

[fire starter]

Designed to meet Indian Army’s most stringent specification & operational conditions, Arjun MBT represents the translation of advanced design into a reliable and effective weapon system to meet the varied threats. Adopting most advanced technologies,Arjun MBT offers the troops in the battlefield, state-of-the-art tank with superior firepower, high mobility, and excellent protection.

Arjun MBT Mk IA is incorporated with much versatile and improved features over Mk-I like Track width mine plough, Roof mounted Driver’s seat, Advanced land navigation system and enhanced night vision capabilities. This tank is also incorporated with Explosive Reactive Armour for enhanced protection and modified Final Drive for improved mobility.

Arjun uses Elbit system's ELAWS LWR (Laser Warning Receiver).



A bigger system ALWACS (Advanced Laser Warning And Countermeasure System) was tested adding VIRCM (Vehicle mounted Infra Red Countermeasure System) but public demos don't seem to include the IRCM.

120mm FSAPDS Mk-2 Ammunition brochure (Origin Unknown)

120mm FSAPDS Mark-II is a DRDO designed prime ammunition for the indigenously developed 120mm ARJUN tank. It is the first time in India that a private sector company was entrusted with and has successfully manufactured this ammunition

120mm Fin Stabilised Armour Piercing Discarding Sabot Mark-II
Description of the technology :
Fin Stabilised Armour Piercing Discarding Sabot (FSAPDS) is the primary ammunitionwith any armoured regiment. 120mm Fin Stabilised Armour Piercing Discarding Sabot (FSAPDS) Mark-II is a single piece ammunition with combustible cartridge case for MBT Arjun. The penetrator is made up of high strength, high density tungsten alloy material. The projectile is fired at very high muzzle velocity. The sabot is discarded just after the muzzle and the penetrator, stabilised by Tail fin unit, travels to the target. On impact with the target, the enormous kinetic energy forces the penetrator to perforate the tank armour. This is sufficient to permanently damage the essentials of tank and harm the tank crew to achieve ‘Total Kill’.
The ammunition is extremely reliable and safe to use. The ammunition has got excellent first round hit probability. The consistency and accuracy of the ammunition are excellent and meet the stringent acceptance criteria of the Indian Army.
The ammunition utilises indigenous Triple Base Propellant with resin base combustible cartridge case. The lethality of the ammunition is much enhanced compared to its predecessor. The shelf life of ammunition is minimum 10 years.

Application Areas :
It is an anti-tank ammunition, which uses Kinetic Energy to defeat the tank armour. The ammunition can be effectively used against all present tanks in service worldwide. It can effectively engage targets at ranges even beyond 2000 meters.

Certifications and test results :
The ammunition has successfully met the stringent acceptance criteria of Indian Army during User Trials and is ready for induction in service

@randombully sir one doubt, what's the difference between ngmbt/fmbt and frcv program, are they two separate indigenous procurement program or different nomenclature for same program?

 

[randombully]

@randombully sir one doubt, what's the difference between ngmbt/fmbt and frcv program, are they two separate indigenous procurement program or different nomenclature for same program?

In simplied language, basically different nomenclature for same program.
It's just that with the new name " FRCV ", they are trying to show it as a more diversified vehicle that can be employed in many roles based on one common platform/chassis.
for example:- future tank, modified future heavy ifv, armoured recovery vehicle, combat engineering vehicle, bridge laying vehicle, SPAAG, command and control vehicle etc.
But it's nothing new, tank chassis has been modified & employed in above mentioned roles for decades.

So, just a fancy name.
But just like any other future tank, it will be designed to be lot more modular than past generation tanks.

so you mean to say frcv program is just a slight modification over arjun tank

and is in anyway ficv and frcv inter related? coz ficv drawing were out

Frcv=" Future ready combat vehicle" program previously known as FMBT&NGMBT.
A.K.A , future tank program.
Mainly to replace our t72 tanks, while upgraded t90s will act as low end tanks in a high low mix.
Here's a list of requirements for what kinda future tank indian army wants.

View: https://x.com/alpha_defense/status/1759619805403820326

FICV= future Infantry combat vehicle.
To replace our bmp2's and other roles.
Currently FICV program is somewhat running more ahead of FRCV program.

But the resulting end products on both program will enter service in 2030s, can even be delayed to ~2035 given our track record.

So what is the current status of FRCV?

it received a new name - project ranjeet

Pretty appropriate name tbh. Goes with the theme. But are there any news about prototype work?

only idrw is reporting about it, cannot trust them until and unless they quote a trusted source

ig saurav jha and sriram talked about it in one of the iah in the last couple of months, i dont remember that sorry

GSQR was only issued not long time ago, it's a document containing detailed requirement of what indian army wants which I showed in previous post, after gsqr is issued relevant parties start detailed design phase of the tank to meet those requirements, so the frcv project ( which was initiated in 2015, a decade ago) is stuck at design phase right now.
And with what Russo ukraine war showed and seeing continous very fast evolotion of tank and anti tank warfare, new modified gsqr can be issued again.

Hypothetically what new things they can add to the already existing design? Anti drone EW suite for tanks??

 

[randombully]

Hypothetically what new things they can add to the already existing design?

Making it Much more repairable.

Autonomous or remotely piloted mode.

Increased gun elevation angle, as lot of times tanks are being used as short range artillary in ukraine, tank on tank battles are still rare.

Probably increased gum size, from 120mm to 130mm gun, for increased range.

More stabilized gun at higher elevation angle, for rapid firing, shoot and scoot.
Which "maybe" also require more faster automatic loader.

Recoil sliding can be introduced, as to reduce the gun weight compared to conventional recoil handling design.



Modified Design so that crew can much easily escape the vehicle in case if they need to( They will need it).

Improved mobility, high mobility is important as shown in ukraine war.

Faster data bus maybe.

More aps launchers, than standard ( standard are 8 apse charges, in four launcher, 2 charges per launcher).

Bigger rciws, probably 30mm or 40mm with fragments ammo against drones.

Engine could be moved to front, to make space for faster entry and exist of crew from back.

Many other things, but these will already increase the weight a lot, and will require complete redesign.

Army will start crying if weight increases. Tbh they have a point. Those old bridges we have can't handle such heavy vehicles. I have an idea can't we fit micro-UAV/FPV launchers into a tank. How complicated that would be?

Already included in current design.
Atgm boxes on sides, can also house uavs.

Improve the infra then.
The problem comes at mountainous and high altitude terrain.

ezsasa sir was right, you are a gem in this field
