India's Defence Self-Reliance: INS Mangrol Delivered and AK-203 "Sher" Rifle Fully Indigenised
Two major Atmanirbhar Bharat milestones in India's defence sector: on August 21, 2026, Cochin Shipyard Limited delivered INS Mangrol, the third Mahe-class Anti-Submarine Warfare Shallow Water Craft, to the Indian Navy; and on August 23, 2026, Indo-Russian Rifles Private Limited (IRRPL) successfully test-fired the AK-203 "Sher" assault rifle made entirely from Indian components — the first 100% indigenised version of the rifle contracted for over 6 lakh Indian Army personnel.

Timeline
Why in News
Two significant milestones in India's defence indigenisation programme emerged in the week of August 23, 2026:
- INS Mangrol — the third vessel of the Mahe-class Anti-Submarine Warfare Shallow Water Craft (ASW-SWC) series built by Cochin Shipyard Limited (CSL), Kochi — was delivered to the Indian Navy on August 21, 2026.
- AK-203 "Sher" assault rifle — Indo-Russian Rifles Private Limited (IRRPL) at its Korwa, Amethi factory test-fired the first AK-203 prototype built with 100% Indian components and input materials on August 23, 2026, marking full indigenisation ahead of army user trials planned for September 2026.
Both developments are direct outputs of the Atmanirbhar Bharat Abhiyan and the Defence Production and Export Promotion Policy (DPEPP) 2020.
Background
India's Defence Indigenisation Journey
For decades, India ranked among the world's largest arms importers, importing 60–70% of its defence equipment from Russia, the US, Israel, and France. The structural shift began with the Defence Procurement Procedure (DPP) revisions from 2011 onward, culminating in the Defence Acquisition Procedure (DAP) 2020, which established priority categories favouring Indian procurement: "Buy Indian — IDDM" (Indigenously Designed, Developed, and Manufactured) at the top, followed by "Buy Indian," "Buy & Make (Indian)," and "Buy & Make." The DPEPP 2020 set a target of achieving a domestic defence production turnover of ₹1.75 lakh crore by 2025 and defence exports of ₹35,000 crore by 2025. Three Positive Indigenisation Lists (PILs) — announced in August 2020, May 2021, and April 2022 — prohibited imports of listed items, compelling India's armed forces to source them domestically.
Part I — INS Mangrol
The ASW-SWC Programme
The Indian Navy identified a capability gap in shallow-water and littoral Anti-Submarine Warfare (ASW). Blue-water ASW platforms (frigates, destroyers) are designed for deep-ocean operations and are less effective in the coastal, continental-shelf environment where submarine threats increasingly originate. To bridge this gap, the Ministry of Defence contracted for 16 ASW Shallow Water Craft split across two parallel programmes:
- Arnala-class (8 ships): Built by Garden Reach Shipbuilders and Engineers (GRSE), Kolkata, and Larsen & Toubro
- Mahe-class (8 ships): Built by Cochin Shipyard Limited (CSL), Kochi
By the time of INS Mangrol's delivery, four Arnala-class ships had already been commissioned. Within the CSL/Mahe-class series, INS Mangrol (Yard No. 525, Pennant P82) is the third vessel, after INS Mahe (commissioned November 24, 2025) and INS Malvan (commissioned July 22, 2026). INS Mangrol was launched on November 30, 2023.
Technical Specifications
| Parameter | Detail |
|---|---|
| Class | Mahe-class ASW Shallow Water Craft |
| Builder | Cochin Shipyard Limited (CSL), Kochi |
| Displacement | 896–1,100 tonnes |
| Length | 78 metres |
| Max Speed | 25 knots |

Armament and Sensors
- RBU-6000: Anti-submarine rocket launcher for shallow-water ASW engagements
- Triple 324mm torpedo launchers: Lightweight torpedoes for both surface and submarine targets
- 30mm Naval Surface Gun: Anti-surface and anti-air capability
- Abhay Sonar: Compact, active hull-mounted sonar designed for shallow-water acoustic performance
- Low-Frequency Variable-Depth Sonar (LFVDS): Can be deployed below the thermocline layer to detect quiet submarines

- Integrated Combat Management System (ICMS) with dedicated ASW processing complex
Strategic Significance
India's 7,516 km coastline spans the Arabian Sea, the Lakshadweep Sea, and the Bay of Bengal. The continental shelf — particularly in the Gulf of Mannar, Palk Strait, and the Andaman Sea — presents shallow-water environments that conventional deep-water ASW platforms cannot cover effectively. Adversary conventional submarines (diesel-electric, air-independent propulsion variants) operating in these waters pose an asymmetric threat disproportionate to their cost. INS Mangrol and its sister ships fill this operational niche while simultaneously demonstrating the capability of Indian public-sector shipbuilding (CSL is a Government of India company under the Ministry of Ports, Shipping and Waterways).
Part II — AK-203 "Sher" Assault Rifle: 100% Indigenisation
The IRRPL Joint Venture
Indo-Russian Rifles Private Limited (IRRPL) was incorporated in 2019 under an Inter-Governmental Agreement (IGA) between India and Russia, specifically to manufacture AK-203 Kalashnikov rifles in India for the Indian Army. The factory is located at the Korwa Ordnance Factory, Amethi district, Uttar Pradesh. Ownership:
| Partner | Stake |
|---|---|
| Advanced Weapons and Equipment India Limited (AWEIL) | 42.5% |
| Munitions India Limited (MIL) | 8% |
| Kalashnikov Concern, Russia | 42% |
| Rosoboronexport, Russia | 7.5% |
| Indian side total | 50.5% |
The supply contract was signed on December 6, 2021 between the Ministry of Defence and IRRPL: 6,01,427 rifles at a value of approximately ₹5,124 crore, with an original delivery deadline of October 2032. Production commenced on January 17, 2023.
The AK-203 Rifle
The AK-203 is a 7.62×39mm assault rifle from the Kalashnikov family. It is a modern variant of the AK-100 series, combining the reliability and ergonomics of the classic Kalashnikov platform with a Picatinny rail system, foldable polymer stock, modern pistol grip, and compatibility with NATO-standard accessories. The Indian Army selected the AK-203 to replace the ageing INSAS (Indian Small Arms System) rifle, which has been in service since 1998. Unlike the 5.56mm INSAS, the 7.62mm AK-203 offers superior penetration — critical in high-altitude and fortified terrain operations.
The Indigenisation Journey
| Phase | Indigenous Content | Notes |
|---|---|---|
| Initial (2022) | ~0% | Technology Transfer (ToT) phase; Russia delivered first batch January 2022 |
| June 2023 | ~5% | First India-assembled models with 5% Indian components |
| May 2024 | ~25% | 27,000 units delivered to Army |
| 2025 | ~30–50% | Component-by-component localisation programme |
| August 2026 | 100% | First prototype test-fired at Korwa; all components and input materials Indian |
The 100% indigenisation involved resolving supply chains for all ~50 major components, ~180 sub-components, and ~120 manufacturing processes. IRRPL developed domestic vendor sources for every element. A key marker of genuine indigenisation: GOST (Russian technical standards) specifications were replaced with Indian Standards (IS) equivalents, meaning the Indian version is not merely assembled from Russian-spec parts but manufactured to India's own specifications with full supply-chain ownership. IRRPL CEO and MD Maj. Gen. S.K. Sharma stated: "We have successfully produced and fired the first AK-203 (Sher) rifle made with 100% Indian components and input materials — a true, end-to-end genuine indigenisation of the rifle."
