CFF Fluid Control is a defence manufacturer that has turned a single early contract - supplying mechanical components for India’s Scorpene submarine programme - into a position as a lifecycle systems integrator for the Indian Navy’s submarine and surface-ship fleet. Founded in 2012 by two marine-engineering veterans, the company has spent a decade moving up the value chain from parts to complete mission-critical systems, using technology transferred from European defence primes and then adapted in its own Indian factories. The recurring approach is straightforward: secure a framework agreement with a global leader such as Naval Group, Atlas Elektronik or NEREIDES, bring the know-how into its Maharashtra workshops, and then supply and maintain that equipment for the full 30-year life of a naval platform - so every new system installed today creates a maintenance revenue stream that can outlast the ship that carries it.
Business segments
A single engine built on one customer relationship - the Indian Navy and its shipbuilders - where every product, from a sonar array to a steering gear, is designed, manufactured and maintained under the same roof.
1. Naval platform systems: the Indian Navy’s single-source equipment partner
CFF designs, builds and services the mechanical, electronic and weapons systems that keep submarines and warships operational, and because it is the authorised manufacturer for those systems, it holds the maintenance mandate for the platform’s entire life.
- Turnkey systems, not just parts - the company delivers complete integrated solutions such as sonar arrays, torpedo-launching mechanisms, high-pressure air systems, steering gear and propulsion controls, functioning as a systems integrator rather than a component vendor.
- Authorised manufacturer status locks in the aftermarket - CFF is the Indian Navy’s Authorised Equipment Manufacturer for mechanical equipment and underwater communication gear on Scorpene-class submarines, which means that when those boats need spares or repairs over their roughly 30-year service life, the work flows back to CFF as the original equipment maker.
- Every major submarine class is on the client list - the company has supplied and serviced equipment for SSK, Kalveri and Kilo-class submarines, and holds orders across the current build programmes: P75, P75 AS, P75(I), SSN and P76 for submarines, plus P-17A frigates, next-generation destroyers and mine vessels for surface ships.
- Empanelment is a three-year barrier - getting approved as a trusted vendor by the Indian Navy typically takes three years of testing and inspection; once inside, the company becomes the default source for the equipment it has qualified on, which is how CFF has built an order book of over ₹590 crore, with 90% coming from defence public-sector undertakings and OEMs.
- Repair teams sit inside the dockyards - the company stations personnel at naval dockyards and shipyards on both coasts, handling everything from mechanical overhauls to electronics and weapon-system repairs, so maintenance revenue is earned on-site rather than waiting for equipment to be shipped back to the factory.
Technology partnerships and indigenisation
CFF’s product catalogue is built on technology-transfer agreements with three European defence houses, each giving it a domestic monopoly on a system the Indian Navy cannot buy off the shelf.
- Naval Group France provides the submarine DNA - a framework agreement covers the transfer of technology for components, equipment and systems, and CFF is now developing steering gear and weapon systems for the follow-on Scorpene boats (P75AS) under that umbrella, having graduated from an earlier technology-transfer licence that it has since completed and now operates independently under royalty.
- Atlas Elektronik opened anti-submarine warfare - a 2024 teaming agreement made CFF one of the only Indian companies manufacturing major anti-submarine warfare systems, starting with an order for 12 indigenous low-frequency variable-depth sonars, described as India’s first indigenised variable-depth sonar system.
- A domestic shipbuilder joins the sonar effort - in mid-2025 CFF signed an MoU with Garden Reach Shipbuilders & Engineers (GRSE) to co-develop subsea-based sonar and jointly bid for contracts, adding a government-owned shipyard to its partner network.
Manufacturing, facilities and workforce
Production happens across two Maharashtra sites approved by the Navy and its foreign partners, with a third facility being fitted out for advanced sonar manufacturing.
- Khopoli is the mother plant - the 6,000-square-metre facility is certified by the Indian Navy, Mazagon Dock and Naval Group France, holds ISO 9001:2015 quality accreditation, and houses the design department that prototypes equipment and systems in-house.
- Pune adds sonar and weapons capacity - a plant was operationalised for weapon systems and sensor production, and a second leased site in Chakan Industrial Area is being set up for future growth and expansion with an investment of ₹5 crore and a 24-month build-out timeline.
Group structure and partners
CFF is a standalone listed entity with no subsidiaries, and its technology moat rests on exclusive relationships with three European defence primes.
- The company has no subsidiaries, joint ventures or associate companies, and its shares trade on the BSE SME platform after an IPO in mid-2023 and a follow-on public offer in mid-2025.
- Its three cornerstone partners are Naval Group France (framework agreement for submarine systems), Atlas Elektronik Germany (teaming agreement for sonar and anti-submarine warfare) and NEREIDES France (technology transfer for towed-wire antenna systems), supplemented by a co-development MoU with GRSE for subsea sonar.
