Kirloskar Brothers boosts naval capability with contribution to INS Taragiri
Kirloskar Brothers Limited, a major Indian engineering conglomerate, contributed key pumping systems to INS Taragiri (F41), India's fourth Project 17A stealth frigate, which was commissioned on April 3, 2026 at Visakhapatnam
INS Taragiri is a Nilgiri-class advanced stealth frigate built at Mazagon Dock Shipbuilders Ltd (MDL), Mumbai, with over 75% indigenous content
The ship features BrahMos missiles, advanced stealth features, and engaged over 200 MSMEs and 4,000 direct workers during construction — completing in ~81 months, faster than the lead ship's 93 months
Three more Project 17A frigates (one at MDL, two at GRSE) are scheduled for delivery by August 2026
Project 17A — India's Indigenous Advanced Stealth Frigate Programme
Project 17A is the Indian Navy's programme to build seven advanced stealth multi-role frigates — a follow-on to the three Project 17 (Shivalik-class) frigates. Designed by the Indian Navy's Directorate of Naval Design (DND), the Nilgiri-class frigates incorporate significant design improvements: better stealth, modular construction, and higher indigenous content. Two shipyards are building them in parallel: Mazagon Dock Shipbuilders Ltd (MDL), Mumbai (four ships) and Garden Reach Shipbuilders & Engineers (GRSE), Kolkata (three ships).
Key Details
- Programme: 7 frigates (4 at MDL, 3 at GRSE)
- Displacement: 6,670 tonnes
- Design: Indian Navy's Directorate of Naval Design — 100% Indian design
- Indigenous content: 75%+ (compared to ~30% in earlier frigates)
- Weapons: BrahMos supersonic cruise missiles, Surface-to-Air missiles (Barak-8), torpedo systems, guns
- Stealth features: hull shaping, infrared suppression, low-noise machinery
- MSME engagement: 200+ MSMEs; ~4,000 direct employees; 10,000+ indirect
- INS Taragiri (F41): 4th ship; commissioned April 3, 2026; built in 81 months (vs. 93 for INS Nilgiri)
Kirloskar Brothers supplying specialised naval pumping systems is an example of how established Indian industrial firms are integrating into the defence supply chain — part of the broader indigenisation mandate.
Defence Indigenisation — Policy Framework and Targets
India's defence indigenisation drive has accelerated under the 'Atmanirbhar Bharat' framework since 2020. The Ministry of Defence (MoD) issues Positive Indigenisation Lists (PIL) — items that cannot be imported; production must be domestic. The Defence Acquisition Procedure (DAP) 2020 categorises procurement to prioritise Indian vendors, with the 'Buy Indian-IDDM' (Indigenously Designed Developed and Manufactured) category at the top of the preference hierarchy. The target is to increase India's domestic defence production to ₹3 lakh crore by 2029.
Key Details
- Positive Indigenisation Lists: 509 items in three lists (2020 onwards) — cannot be imported
- Defence Acquisition Procedure (DAP) 2020: replaces DPP 2016; prioritises Indian vendors
- 'Buy IDDM' category: highest preference for Indian-designed-and-made platforms
- Defence Production & Export Promotion Policy (DPEPP) 2020: target ₹1.75 lakh crore production by 2025, ₹35,000 crore exports
- DPSUs (Defence Public Sector Undertakings): HAL, MDL, GRSE, BEML, BEL, Ordnance Factories (now 7 companies)
- iDEX (Innovations for Defence Excellence): startup engagement for defence technology
- Two Defence Industrial Corridors: Uttar Pradesh (Lucknow–Agra–Aligarh) and Tamil Nadu (Chennai–Coimbatore)
INS Taragiri's 75% indigenous content and MDL's construction capability represent a benchmark for the broader Atmanirbhar defence ecosystem; Kirloskar's pump supply is a model for MSME-to-defence integration.
Indian Navy's Maritime Security Role and Frigate Capabilities
Frigates are multi-role warships (3,000–10,000 tonnes) — suited for anti-submarine warfare (ASW), anti-air warfare (AAW), and surface strike. In India's maritime strategy, frigates are workhorses of the Indian Ocean patrol and response force. The Indian Ocean Region (IOR) is India's strategic sphere — India's 7,516 km coastline, exclusive economic zone (EEZ), and island territories require sustained naval presence. Project 17A frigates significantly enhance the Navy's ability to conduct sustained high-sea operations.
Key Details
- India's coastline: 7,516 km; EEZ: 2.37 million km² (6th largest in world)
- Indian Navy fleet (2026): 2 aircraft carriers, 6 destroyers, 13+ frigates (including new 17A ships), 16 conventional submarines
- BrahMos: India-Russia joint venture supersonic cruise missile (Mach 2.8–3); range ~300–500 km
- Barak-8: India-Israel jointly developed medium-range SAM system
- GRSE (Garden Reach Shipbuilders & Engineers): Kolkata-based; building 3 of 7 Project 17A ships
- MDL (Mazagon Dock Shipbuilders Ltd): Mumbai; primary builder of frigates and submarines
- QUAD naval cooperation: India-US-Japan-Australia maritime security alignment
Commissioning Project 17A ships at an accelerating pace (81 months vs. earlier 93 months) signals growing shipbuilding capacity — critical as China rapidly expands its naval fleet and IOR presence.
- INS Taragiri (F41): commissioned April 3, 2026 at Visakhapatnam

- Weapons: BrahMos missiles, Barak-8 SAMs, torpedo systems
- MSME involvement: 200+ firms; 4,000 direct / 10,000 indirect jobs
- Construction time: 81 months (vs. 93 months for lead ship INS Nilgiri)
- Remaining ships: 3 to be delivered by August 2026 (1 at MDL, 2 at GRSE)
