The Bharat ULH 155-mm/39 caliber (Ultra-Light [[Howitzer]]), created by Kalyani Strategic Systems, serves as the basis for the MaRG 155-BR, also known as the '''TS-20'''. Three versions of the ULH were created using various structural materials for the carriage and recoil devices: titanium (weight 4.8 tons), steel (all steel, total weight 6.8 tons), and mixed (Advance Hybrid). Based on the steel version of the ULH, the artillery unit was placed on the MaRG 155-BR. The four-by-four-wheel self-propelled vehicle is based on the [[Ashok Leyland]] Mark 4 military truck and has a five-person armored cabin. It has a contemporary fire control system installed.<ref>{{Cite web |last=Chacko |first=Joseph P. |date=2022-11-13 |title=Armenia buys the 155-mm / 39 self-propelled howitzers, Kalyani MArG 155 - BR, from India |url=https://frontierindia.com/armenia-buys-the-155-mm-39-self-propelled-howitzers-kalyani-marg-155-br-from-india/ |access-date=2026-02-15 |website=Frontier India |language=en}}</ref><ref>{{Cite web |last=Patel |first=Raghav |date=2025-02-12 |title=Bharat Forge Rolls Out MArG 155mm/45 Wheeled Self-Propelled Howitzer with Rapid Deployment, Extended Range and Precision Fire Capabilities |url=https://defence.in/threads/bharat-forge-rolls-out-marg-155mm-45-wheeled-self-propelled-howitzer-with-rapid-deployment-extended-range-and-precision-fire-capabilities.12850/ |access-date=2026-02-15 |website=Defence News India |language=en-US}}</ref>

On the advice of Indian [[Chief of Defence Staff (India)|Chief of Defence Staff]] [[Bipin Rawat]], '''MaRG 39''' was developed by Bharat Forge. At DefExpo 2020, it was showcased for the first time. Mounted on a 4x4 [[BEML]]-[[Tatra (company)|Tatra]] [[chassis]], the 7.8 tonne, 155 x 39 mm lightweight howitzer is known as the truck-mounted MaRG-Steel. With an overall weight of 18 tons, the system is developed for high altitude terrain like [[Ladakh]] and [[Arunachal Pradesh]], where it has proven logistically challenging to deploy heavy artillery. The [[Ilyushin Il-76]], and [[Boeing C-17 Globemaster III]] are capable of airlifting the MArG. One MaRG MGS can be flown by the IL-76, and the C-17 can airlift two MaRG MGS.<ref name=":1" />

Bharat Forge unveiled the Multi-terrain Artillery Gun (MaRG) 155-BR on 21 December 2021, in front of Indian [[Chief of the Army Staff (India)|Chief of the Army Staff]] [[General (India)|General]] [[MM Naravane]], and the [[Defence Minister of India|Defense Minister]] [[Rajnath Singh]].<ref>{{Cite web |date=2021-12-26 |title=Pune: Indigenous Multi-terrain Artillery Gun launched |url=https://indianexpress.com/article/cities/pune/pune-indigenous-multi-terrain-artillery-gun-launched-7690927/ |access-date=2026-02-15 |website=The Indian Express |language=en}}</ref> The MaRG 155-BR is one of the few 155mm/39 caliber gun systems installed on 4x4 High Mobility Vehicle (HMV). It has the capacity to [[shoot-and-scoot]]. The [[Indian Armed Forces]] offered assistance and direction for the project's development.<ref name=":0" /> With a typical [[high-explosive]] [[Fragmentation (weaponry)|fragmentation]] round, MaRG 39 can fire up to {{convert|24|km|mi|2|abbr=on}}.<ref>{{Cite web |title=Armenia Strengthens Defense With Indian Akash SAMs and Pinaka MLRS |url=https://militarnyi.com/en/news/armenia-strengthens-defense-with-indian-akash-sams-and-pinaka-mlrs/ |access-date=2026-02-15 |website=Militarnyi |language=en-US|date=2026-02-08|last=Pryhodko|first=Roman}}</ref>

In addition to offering a platform for the loader and room to store a spare wheel, the stabilizer aids in distributing the considerable forces that are imparted onto the vehicle during the gun's recoil.<ref name=":3">{{Cite web |last=Petrov |first=Christopher |date=2025-02-20 |title=IDEX 2025: Kalyani unveils longer-range 4×4 155 mm artillery system |url=https://www.janes.com/osint-insights/defence-news/land/idex-2025-kalyani-unveils-longer-range-44-155-mm-artillery-system |access-date=2026-02-15 |website=janes.com |language=en}}</ref>

== Variant ==

* The MaRG 45 variant is a 155mm/45 caliber system which is placed on a 4x4 all-terrain high-mobility vehicle. The MaRG 45 is made to deploy quickly. It is compatible with [[NATO]]-standard and Indian Army in-service rounds and can fire conventional ammunition more than {{convert|36|km|mi|2|abbr=on}} away. With Zone 6 firing capability, the system can carry 18 artillery rounds and weighs 23.5 tons in total. The chassis guarantees excellent maneuverability on a variety of terrains. It traverses 25° on both the left and right sides and ranges in elevation from -2° to +72°. For rapid-response operations in tough and inaccessible areas, the deployment time is 1.5 minutes during the day, and 2 minutes at night. MaRG can fire 10 rounds in 3 minutes at an intense rate and 42 shots in 60 minutes at a steady rate. The system was created by KSSL as a substitute for the [[K9 Thunder]], [[ATMOS 2000]], and [[CAESAR self-propelled howitzer]].<ref>{{Cite web |title=Kalyani Group unveils MArG 155mm/45 Cal MGS at IDEX 2025 |url=https://www.vayuaerospace.in/Issue/202504041055513540.pdf |access-date=2026-02-16 |website=vayuaerospace.in}}</ref><ref>{{Cite web |last=Sathe |first=Vipul |date=2025-02-19 |title=Kalyani Group Unveils MArG 155mm/45 Cal at IDEX 2025 |url=https://www.motoroids.com/interesting-humorous-and-others/kalyani-group-unveils-marg-155mm-45-cal-at-idex-2025/ |access-date=2026-02-15 |website=motoroids.com |language=en-GB}}</ref><ref name=":2" />

* The smallest 155 x 52 mm mounted gun system in the world, the '''MaRG 52''', was introduced by KSSL in 2026. It weighs 24 tons when mounted on a Kalyani 4x4 vehicle. It makes use of an [[autoloader]] and an aluminum [[gun carriage]]. It features [[shoot-and-scoot]] functionality and can fire five rounds per minute. It is a component of the progression that started with MaRG 39 and continued with MaRG 45. Since 155 x 52 mm howitzers are typically only installed on 6x6 or 8x8 trucks, the MaRG 52 is a compact weapon.<ref name=":1" />

== Export ==
An unidentified friendly foreign nation placed an export order with Kalyani Strategic Systems on 9 November 2022, for the production of 155-mm artillery gun platforms within three years. The deal is for $155.5 million.<ref>{{Cite web |last=Chacko |first=Joseph P. |date=2022-11-13 |title=Armenia buys the 155-mm / 39 self-propelled howitzers, Kalyani MArG 155 - BR, from India |url=https://frontierindia.com/armenia-buys-the-155-mm-39-self-propelled-howitzers-kalyani-marg-155-br-from-india/ |access-date=2026-02-15 |website=Frontier India |language=en}}</ref><ref>{{Cite web |date=2025-02-19 |title=IDEX: Bharat Forge eyes export market for artillery systems |url=https://aviationweek.com/aerospace/idex-bharat-forge-eyes-export-market-artillery-systems |access-date=2026-02-22 |website=aviationweek.com}}</ref>
