India’s Electromagnetic Railgun: The Future Of Artillery

The Indian Army is exploring one of the most advanced weapon systems ever developed by DRDO, the electromagnetic railgun. During a visit to ARDE Pune, the Consultative Committee of the Ministry of Defence was briefed on this ambitious project. Unlike conventional artillery that relies on chemical propellants, a railgun uses powerful electromagnetic force to launch a solid projectile at hypersonic speeds of nearly Mach 6. With this programme, India joins a small group of nations working on operational railgun technology. While challenges remain in power generation and material durability, DRDO says key enabling technologies are already in place, with battlefield integration expected in the coming decade.

May we know the questions?

Very noob questions, Ramana ji. Almost ashamed to ask here. Since I don't have any engineering background whatsoever.

But valuing knowledge more than shame here are a few...

Is it like an add-on 'kit' which can be added on to existing shells (not exactly alike but along the lines of the JDAM). If yes, can be done on the field? Also does it require any changes to the firing gun? If yes then can the gun be reconfigured quickly (in the field) to fire regular shells.

Or is it a modification which needs to be 'manufactured in' during the shell production stage.

What effect does it have on

a) storage - do these shells/the add on require special (additional) care in storage and transport (including packaging)?

b) shelf life - any difference in the shelf life of the shell and the add on kit (if they are different units). If yes can newer add on kit be added on to the older shells. And vice versa.

Added - my thoughts are that it is a very good development and very, very welcome. Hoping that all concerned stay on the R&D path to implementation and improvement. If it is a costly system then use it as tip of the spear, if not then use it as a volley of spears. But use it.

My 2 paisa..

- This will most likely not be an add on kit (like the excalibur guidance kits) there is most likely some kind of sealing needed to ensure the shell doesnt separate from the ramjet base immediately on firing.. would be interesting to know how this is actually done

- This would mean some special handling requirements with slightly stricter protection protocols for the rounds, like, better environmental seals for storage and transportation. Definitely some logistics change needed.

- Shelf life would be a factor too, IMHO, and as per my first statement, this would not be field replaceable...

Happy to be corrected on the above..

[Manish_P]

I think so too.

The images shared in earlier posts hint at it.

More info will come out in due course.

Exciting times for Indian artillery

[pravula]

Its likely similar to JDAM conversion kits. Needs to be mounted at a factory using existing shells. Not field modified like excalibur kits.

IIT-M variant is like that.

While there is another version from DRDO which is much more like a mini Brahmos ---> https://www.indiandefensenews.in/2025/0 ... wered.html

Below is the video that explains everything. This replaces the base bleed with the ramjet. The air scoop is at the rear. Essentially, you can screw the ramjet part onto any 155mm shell. Amazing !

India Leads the World in Ramjet Shell Technology

India may have just rewritten the future of artillery warfare. In this exclusive conversation with Chakra News, Lieutenant General P. R. Shankar reveals how India became the first country to successfully fire a ramjet-powered artillery shell. Unlike global designs that trade firepower for range, this breakthrough uses a rear-intake, modular ramjet attachment that fits existing 155 mm shells. Developed through a rare Army–IIT collaboration, this innovation could redefine long-range firepower, logistics, and battlefield dominance.

a)The current base bleed motor is factory-installed by the shell assembler. So this ramjet module is a plug-and-play replacement for the base bleed motor and will also be factory-installed.

Current base bleed motor cross section view.



The storage and transport will be similar to the base bleed motor, as the propellant is the same.
b)Should be the same as the base bleed shells for reasons already stated.

c)The module should cost the same as the base bleed shell. In fact, the cost of machining should be lower as there is no need for the intricate angle drilled nozzles and they can be replaced with a large nozzle for the ramjet.

[ramana]

Lt Gen Shankar says it's field modification and not factory installation.

I was incorrect.

[Manish_P]

Field modification

Wow. That's a proper game changer.

Hoping they stay the course to full implementation across the spectrum.

[Manish_P]

SSS defence founder had made a post referencing 'Jawab-e-hind'. An Indian answer. Referring to origins of excellent Damascus steel swords made by using ancient Indian metallurgy.

This Ramjet shell will go right to my personal list of 'Jawab-e-Hind'.

The SMART torpedo system is the other item in that list.

Hopefully the list will be a 'Navratna' list in the next few years

[sudhan]

Field modification is incredible!

when combined with a precision guided artillery shell and top notch ISR, we can dominate upto ~70 kms into the paki territory without sending a single soldier/jet or expending a costly missile

Kalyani Challenging DRDO! | Impressive Innovation

Kalyani is developing a 155/52 caliber mounted gun on a 4 wheel truck; weighing only 24 tons.

[Manish_P]

Text style article of the above news

Bharat Forge Unveils World’s First 155mm/52 Artillery Gun on 4×4 Chassis

In a breakthrough that could significantly reshape India’s artillery doctrine, Bharat Forge has unveiled what it describes as the world’s first 155mm/52-calibre artillery gun mounted on a 4×4 high-mobility chassis, achieving a combination of firepower, mobility and weight reduction previously considered impractical. Weighing just 24 tonnes, the system has completed initial development and internal trials and is now set to undergo formal testing at the Proof and Experimental Establishment (PXE), Balasore, Odisha.

A New Class of Mobile Heavy Artillery

The newly developed gun system represents a radical departure from conventional mounted artillery platforms. Traditionally, 155mm/52-calibre guns — the global benchmark for long-range tube artillery — require heavy 6×6 or 8×8 trucks to absorb recoil forces and maintain firing stability. By contrast, Bharat Forge’s platform compresses the same firepower onto a compact 4×4 chassis, reducing overall mass by nearly seven tonnes when compared to the mounted variant of the Advanced Towed Artillery Gun System (ATAGS), which weighs around 31 tonnes.

Strategic Mobility for the Himalayas

Military planners have long sought a heavy gun that can be rapidly deployed in high-altitude terrain, particularly along the Line of Actual Control (LAC), where road width, bridge load classifications and steep gradients restrict the movement of heavier platforms. The lighter 4×4 configuration allows the gun to traverse narrow mountain roads and bridges that are inaccessible to conventional mounted systems.

The reduced weight and footprint also enhance strategic airlift capability. The system can be transported more efficiently by Indian Air Force heavy-lift aircraft, such as the C-17 Globemaster, enabling faster redeployment between theatres — a key requirement in a two-front contingency.

Firepower Without Compromise

Officials familiar with the programme indicate that the gun is expected to achieve ranges of 40–45 kilometres with standard ammunition, with the potential to exceed 50 kilometres using advanced extended-range and ramjet-assisted projectiles currently under development in India.

The system incorporates a semi-automatic loading mechanism, maintaining a high rate of fire while reducing crew fatigue and exposure. This feature is particularly important in high-altitude conditions, where physical exertion significantly affects sustained operations.

Recoil Management: The Core Challenge

The central technical question surrounding the project has been whether a 4×4 platform can withstand the intense recoil forces generated by a 52-calibre gun during sustained firing. Bharat Forge has addressed this through a combination of patented soft-recoil technology, reinforced chassis architecture and advanced hydraulic stabilisers designed to anchor the vehicle during firing sequences.

Implications for India’s Artillery Modernisation

A successful 155mm/52-calibre gun on a 4×4 chassis would introduce an entirely new category of artillery — combining long-range firepower, rapid shoot-and-scoot capability and exceptional deployability.

As the prototype moves to Balasore for its most critical evaluations yet, defence observers view the programme as a high-risk, high-reward effort (# the risk is being taken by the private company on it's own). If validated, it could redefine how heavy artillery is designed, deployed and employed — not only for India, but for modern armies worldwide.

May they get a lot of export orders. Will help funding for their R&D program.

RAMJET powered Pinaka test in March | Range 240Km

Ramjet for Grad / Pinaka rockets (what the article says is NEXT). This is where things change. Rockets cannot use the exact same base-ramjet layout because: The base is occupied during boost. At launch, the rear is: Solid rocket motor. High-temperature exhaust plume. Structural thrust loads. So you can’t run a ramjet there at the same time. That means rocket ramjets must be staged propulsion systems.

[Aditya_V]

I also that like Rampage there is a variant which can be aircraft launched, should give it additional range and gives the ability to make Pakistan Nishastra fast.

There could be an aircraft launched variant of the Ramjet once it succeeds with Pinaka, going even greater range than the land launched Ramjet variant.

Kalyani should become a 100% export oriented country. Building for our DG Artillery is like casting pearls before a swine

[Manish_P]

Our arms sales are on upward trajectory. Check the new thread on Atmanirbhar Bharat.

IMHO we should have a full fledged Ministry of Arms & Ammunition Sales & Exports. Should be separate from the defence and industries ministry. Can be additional charge for Raksha Mantri but eventually have a cabinet level minister of its own.

DRDO Plans to Expand Pinaka Long-Range Guided Rocket Family with New 300 km and 450 km Precision Rockets
https://defence.in/threads/drdo-plans-t ... ets.17013/
28-2-2026

Following the successful validation of the 120 km variant in late 2025, DRDO is now focusing on extending this reach significantly.

Ankathi Raju, Director of the Armament Research and Development Establishment (ARDE), confirmed that the 300 km model is currently in the design phase.

This system is anticipated to begin initial trials within three years, with the goal of entering active service within five years.

Simultaneously, a 450 km version is being developed using the same core technology to become one of the longest-reaching guided rockets globally.

414 was the original plan for Dhanush- 114+300, ATAGS, MGS, Indian Light howitzers, more indigenized K-9, more mobile 105mm all are required.

I think right now we must be having 300 Original Bofors, ~100 Dhanush, 180-250 converted 130 mm, 145 M777, ~100 K-9, 100 K9 on order, 400 ATAGS in production, a far cry from 300 Bofors in 2014.

OFB has not finished the original order from the first batch. In light of this, ordering any more in the thousands is counter productive.

OFB should be thankful that the Army even ordered a follow on batch of 300 more. This is OFB we are talking about.

Placing order for parts and all takes time. So when the first lot is finished, the second lot part and all should be ready to continue production. We usually delay decision making and end up with nothing. This is the right way to do it. Either order together or even if ordered in batches, place order before the first lot production ends. This is the status of the first lot

In principle, yes.

The original order was supposed to be completed by March 2026. That will not happen, due to OFB's inefficiencies. Another poor showing by a Govt PSU. In light of this, it does not give the user much confidence in ordering these guns in the thousands.

A good measure of comparison would be Bharat Forge & TASL that received the order for 307 ATAGS on 26 March 2025. Lets see if the private manufacturer will meet their contractual obligations in delivery timeframes. These two companies are not Govt PSUs and thus there is sufficient in-house pressure to ensure that deliveries are met. Failure to meet those timelines, could result in Bharat Forge & TASL losing future contracts.

Understandable. That's why 300 lot is good order for defense PSU.

Hopefully, the follow on order for ATAGS follow on will be larger. ATAGS delivery has started as per one report.

Army’s first regiment of long-range ATAGS artillery guns to be ready by February 2027

“The first gun system is ready for the mandatory first of product model test. The first regiment of 18 ATAGS will be inducted within a year thereafter,” said RP Pandey, Project Director (PD) of ATAGS, speaking to The New Indian Express.

Since he said this in Jul 2025, we could expect the 18 within Jul 2026? probably one year after the product model test. Which must be taking about 6 months based on the February 2027 timeline.

[Rakesh]

Since he said this in Jul 2025, we could expect the 18 within Jul 2026?

That is the metric to watch out for. Pin your post and visit back at the end of July 2026, to see if the private manufacturer has met its obligation.

If they also fail, then Army HQ will import a gun.

The company's recent success in exporting nearly 100 artillery guns in 2024 highlights its growing international presence. This achievement demonstrates KSSL's capacity to deliver high-quality, combat-proven systems to foreign customers.

^^^
Not a single artillery gun needs to be imported. They have already exported six ATAGS to Armenia and got a follow on order of 84 ATAGS. Another order of 18 ATAGS from an European nation delivered. An order from West Asian nation also reported. Then there is the 72 mArG shipped to Armenia in 2026, The Indian Army is late in placing orders.

Atmanirbharata is the Govt's initiative. If the services are delaying orders of local maal, then it rests on the Govt's shoulder to enforce its own policy.

It take two hands to clap (import) ---> The service who "wants" the import and the Govt who "funds" the import. The services report to the Govt and not the other way around.

[ramana]

Rakesh and Uddu,
The Dhanish follow in order for 300 guns was stuck due to some scandal about bearings origin investigation.
The babus/ generals were saying let the investigation finish. PMO said let the investigation continue and meantime order the guns.

[Tanaji]

Am I right in saying that the confirmed orders so far are:

ATAGS: 307 split between 184 to Bharat Forge, 123 to Tata Advanced Systems
Dhanush: 114 units initially ordered. They may order 300 more
K9 Vajra: 100 delivered plus may order 100 more
M777: 145 delivered

No orders for mountain guns or truck mounted yet

If the above is correct then the ATAGS order speaks volumes.

To this you can also add 300 Sharang guns (130mm to 155mm upgrade by OFB) ordered. However, procurement was stopped after 159 guns due to quality issues. Soltam also upgraded 180 guns (130mm to 155mm) and these were delivered way back in 2008 or so.

DRDO’s ‘shoot and scoot’ mounted gun system ready for Indian Army trials
https://www.indiasentinels.com/defence- ... rials-6921
Cost edge and strategic significance
July 11, 2025.

The Defence Research and Development Organization, on Monday, announced that the 155mm/52 calibre truck-mounted howitzer has successfully completed internal trials and is ready for extensive field testing across diverse terrains and weather conditions. The system, weighing approximately 30 tonnes, has already fired over 100 rounds during rigorous testing at Balasore and Pokhran ranges, validating its operational reliability.

Senior DRDO officials confirmed that the mounted gun system has demonstrated exceptional mobility, transitioning from transport mode to firing position in just 80 seconds and relocating within 85 seconds after firing.

The indigenous mounted gun system offers exceptional value compared to international alternatives, with unit costs approximately ₹15 crore ($1.74 million) significantly undercutting foreign competitors. For perspective, the French Caesar system costs $4.26 million, the Serbian Nora B-52 requires $7.06 million, and the Swedish Archer demands $10.41 million per unit.

The trials are expected to conclude within the next six months, with potential induction into service following successful completion of all evaluation parameters.

This is interesting. The DRDO gun is 52 cal as compared to the MaRG one from Kalyani that is presumably lighter by at 6.5 tons but is 45 cal. However the MaRG can be carried on the C390 but DRDO one cannot… horses for courses but this one has a role.

Lets see how many orders any of these get.
