India’s defence manufacturing story is no longer limited to Bharat Electronics or Hindustan Aeronautics. A growing group of small and mid-sized companies is quietly supplying the components, systems, and specialised equipment that keep warships, fighter jets, and satellites operational. This guide covers 10 such names: Kaveri Defence, Jaykay Enterprises, Avantel, DCX Systems, TechEra Engineering, C2C Advanced Systems, Aequs, Digilogic Systems, Taneja Aerospace, and Shree Refrigerations.
Some are well-tracked mainboard companies. Others trade on the SME platform with thinner volumes. We examine what each company actually does, where it sits in the supply chain, and the key points investors should consider before adding any of them to a portfolio.
Why India’s Defence Stocks Are Drawing Attention
India’s defence budget has expanded sharply over the past decade — from roughly ₹2.53 lakh crore in FY2013-14 to about ₹7.85 lakh crore in FY2026-27. Capital expenditure for new equipment reached around ₹2.19 lakh crore in the latest year.
Private-sector participation has also risen meaningfully. Private players now account for close to 24% of India’s defence production, up from a much smaller share a decade earlier. Active defence industrial licences have increased from 258 in 2015 to 834 by March 2026.
Four rounds of positive indigenisation lists now mandate that hundreds of defence items be manufactured in India rather than imported. This policy backdrop, combined with rising order books, is driving investor interest in smaller defence-linked manufacturers alongside the traditional PSU giants.

FY 2025-26 Net Profit: Company-by-Company
“Last year” refers to FY 2025-26 (year ended 31 March 2026), the most recent completed and audited fiscal year. Figures below are net profit after tax as reported to the exchanges.
| Company | FY26 Net Profit | FY25 Net Profit | YoY Change |
|---|---|---|---|
| Kaveri Defence & Wireless Technologies | ₹1.24 Cr | ₹6.41 Cr | Down 80.7% |
| Jaykay Enterprises | ₹215.65 Cr* | ₹7.17 Cr | Up sharply* |
| Avantel Limited | ₹14.99 Cr | Higher base year | Down 73.4% |
| DCX Systems Limited | Net loss of ₹7.71 Cr | ₹38.88 Cr profit | Swung to loss |
| TechEra Engineering (India) Ltd | Approx. ₹3.08 Cr | ₹3.36 Cr | Roughly flat |
| C2C Advanced Systems Ltd | ₹18.33 Cr | ₹28.84 Cr | Down 36.4% |
| Aequs Limited | Net loss of ₹113.3 Cr | Loss-making in FY25 | Remained loss-making |
| Digilogic Systems Limited | ₹10.43 Cr | ₹7.79 Cr | Up 33.8% |
| Taneja Aerospace and Aviation Ltd | ₹16.81 Cr | ₹18.08 Cr | Down 7.0% |
| Shree Refrigerations Limited | ₹21.53 Cr | ₹12.61 Cr | Up 71.0% |
*Jaykay’s FY26 profit was heavily influenced by a one-time ₹262.66 crore investment valuation gain, not core operations. Treat it as an outlier.
Only three companies delivered genuine organic profit growth: Digilogic Systems, Shree Refrigerations, and (on paper) Jaykay. DCX Systems and Aequs both moved into losses despite higher revenue. The gap between rising sales and falling profitability deserves close attention.
1. Kaveri Defence & Wireless Technologies
Kaveri Defence (formerly Kavveri Telecom) has designed and manufactured RF and microwave components since 1996. The Bengaluru-based company produces antennas, filters, and signal combiners for telecom, defence, and space customers. Its portfolio includes defence communications, counter-drone systems, and satellite telemetry.
The stock trades on the NSE mainboard with a market capitalisation of roughly ₹340–360 crore. It remains debt-free as of FY2026, which lowers balance-sheet risk. However, the business is relatively small and order flows can be lumpy.

FY26 net profit fell sharply to ₹1.24 crore (down 80.7% from ₹6.41 crore in FY25). Revenue also declined over the same period. This is a company that requires close monitoring rather than one that can be assumed to be on autopilot.
2. Jaykay Enterprises
Jaykay Enterprises has a long corporate history as part of the 140-plus-year-old JK Organisation (formerly J.K. Synthetics). The company has pivoted strongly into defence and aerospace engineering, focusing on composite applications and underwater mine components.
Its subsidiary JK Defence & Aerospace acquired a Hyderabad-based composites firm to strengthen this shift. Jaykay has also secured orders from BrahMos Aerospace for PCB warhead casing assemblies. With a market capitalisation above ₹2,000 crore, it is one of the larger names on this list.
FY26 net profit jumped to ₹215.65 crore from ₹7.17 crore in FY25. Most of the increase came from a one-time ₹262.66 crore investment valuation gain rather than the core defence business. Investors should examine operating numbers separately.
3. Avantel Limited
Avantel is a Hyderabad-based satellite communication specialist founded in 1990. It develops software-defined radios, satellite and HF communication systems, and radar technology. The Indian Navy uses its satcom products across ships, submarines, and aircraft.
Recent orders include work for DRDO, HAL, and Larsen & Toubro. Despite this, FY26 revenue declined more than 10% year-on-year and profit fell sharply. The stock continues to trade at a high valuation (triple-digit P/E), so valuation risk remains elevated.
FY26 net profit stood at ₹14.99 crore, down 73.4% year-on-year — a steep drop for a stock still commanding a premium multiple.
4. DCX Systems Limited
DCX Systems, based in Bengaluru, has manufactured cable and wire harness assemblies for defence and aerospace clients since 2011. It acts as an Indian Offset Partner for global OEMs including ELTA Systems and Israel Aerospace Industries.
The company holds a Defence Industrial Licence and AS-9100 certification for aviation manufacturing. The stock has declined roughly 32% from its 2025 highs as of mid-2026. Rising receivables and slower cash conversion have been flagged as concerns by analysts.
DCX Systems reported a consolidated net loss of ₹7.71 crore in FY26, versus a ₹38.88 crore profit in FY25 — a meaningful reversal that prospective investors should weigh carefully.
5. TechEra Engineering (India) Limited
TechEra Engineering designs and builds precision tooling for aircraft assembly lines, including jigs, fixtures, and MRO tooling used on light combat aircraft, fighter jets, and helicopters. It listed on the NSE SME platform in October 2024.
Aerospace tooling accounted for about 59% of its FY2024 revenue, with automation solutions making up the balance. Market capitalisation remains under ₹310 crore. As an SME stock, trading volumes are typically thin, which can lead to sharper price swings.
Net profit for the trailing year was approximately ₹3.08 crore, broadly flat against FY25’s ₹3.36 crore. Profit growth has largely stalled even as the share price has remained volatile.
6. C2C Advanced Systems Limited
C2C Advanced Systems develops defence electronics for air, sea, and land platforms. Its offerings include Combat Management Systems, C4I systems, and anti-drone command-and-control technology. The Bengaluru firm has delivered combat management systems for two Malaysian navy frigates.
SBI Management Fund Stock Pre Analysis? https://dailystocks7.com/2026/07/19/sbi-funds-management-stock-a-deep-dive-analysis-for-investors/
It listed on NSE SME in December 2024 and has since won a Hindustan Shipyard order valued at ₹160–180 crore for naval display systems, along with multiple counter-drone contracts. High debtor days remain a watch point.
FY26 net profit declined to ₹18.33 crore from ₹28.84 crore in FY25, even though revenue rose 26.5%. Auditors have flagged liquidity concerns and going-concern doubts — a significant red flag that warrants careful reading of the full financial statements.
7. Aequs Limited
Aequs is by far the largest company on this list, with a market capitalisation near ₹17,000–17,700 crore. It operates a vertically integrated aerospace manufacturing SEZ producing engine, landing-gear, and structural components for Airbus, Boeing, and Safran.
An important distinction: Aequs is primarily a commercial aerospace supplier rather than a pure defence contractor. Around 89% of FY25 revenue came from aerospace, largely export-driven. It listed in December 2025 and has more than doubled from its issue price.
On a consolidated basis, Aequs posted a net loss of ₹113.3 crore in FY26 despite 33% revenue growth. Standalone (parent-only) results showed a ₹49.8 crore profit, aided by one-time gains and impairment reversals. The gap between standalone and consolidated numbers is worth understanding in detail.
8. Digilogic Systems Limited
Digilogic Systems, based in Hyderabad, designs Automated Test Equipment, radar simulators, and Electronic Warfare test systems. It has supplied DRDO, the Indian Air Force, and several defence PSUs for more than 18 years. The company listed on the BSE SME platform in January 2026.

The stock rose 56% in three trading days in August 2026 following fresh Ministry of Defence orders — a move that illustrates both the opportunity and the volatility typical of small, order-driven SME defence stocks.
FY26 net profit increased 33.8% to ₹10.43 crore from ₹7.79 crore in FY25. It was one of the few companies on this list that delivered genuine organic profit growth.
9. Taneja Aerospace and Aviation Limited
Taneja Aerospace (TAAL) has operated since 1988 from Tamil Nadu. It focuses on aircraft maintenance, repair and overhaul (MRO), helicopter testing, and aerospace component manufacturing. The company has been listed since the mid-1990s.
TAAL is a smaller, relatively steadier name compared with the newer IPO-driven stocks on this list. Market capitalisation is around ₹700–800 crore. The stock has been volatile through 2026, moving between roughly ₹190 and ₹455 over the past year.
Standalone net profit for FY26 was ₹16.81 crore, down slightly from ₹18.08 crore in FY25. Profitability has held up reasonably well relative to several newer names.
10. Shree Refrigerations Limited
Shree Refrigerations manufactures marine chillers and HVAC systems for warships and submarines from its facility in Karad, Maharashtra. Management claims a 60–70% share of India’s defence-marine cooling market, built over two decades of specialised naval work.
The company listed on BSE SME and has grown rapidly, with FY26 revenue rising approximately 50% year-on-year. Clients include Mazagon Dock, Hindustan Shipyard, and Goa Shipyard. It has also entered a data-centre cooling partnership to diversify beyond defence.
FY26 net profit rose 71% to ₹21.53 crore from ₹12.61 crore in FY25 — the strongest organic profit growth among the ten companies.
Where Each Company Fits in India’s Defence Supply Chain
Not every “defence stock” performs the same role. Here is how the ten companies map across the supply chain:
| Supply Chain Segment | Companies |
|---|---|
| Radar, EW & communications electronics | Avantel, Kaveri Defence, Digilogic Systems, C2C Advanced Systems |
| Aerostructures & precision manufacturing | Aequs, TechEra Engineering, DCX Systems, Jaykay Enterprises |
| Aircraft MRO & assembly services | Taneja Aerospace |
| Naval & marine support systems | Shree Refrigerations |
This mapping is important. A radar-electronics company and an aircraft-tooling company face very different demand cycles, even if both fall under the broad “defence” label.
Mainboard vs SME Defence Stocks: Know the Difference
Six of these companies trade on the NSE or BSE mainboard: Kaveri Defence, Jaykay Enterprises, Avantel, DCX Systems, Aequs, and Taneja Aerospace. Four trade on the SME platform: TechEra Engineering, C2C Advanced Systems, Digilogic Systems, and Shree Refrigerations.
SME stocks typically have smaller public floats and lower daily trading volumes. Price moves can be sharper on modest order flow, in both directions. Lot sizes are also larger, so the minimum investment tends to be higher than for mainboard stocks.
Mainboard stocks generally offer better liquidity and longer disclosure histories. That does not make them automatically safer — Avantel and DCX Systems, both mainboard names, have experienced sharp price swings through 2026 as well.
Bull Case and Bear Case
Bull case: India’s defence capital expenditure is rising rapidly, and indigenisation rules are forcing greater local sourcing. Order books across this group are expanding, with fresh contracts from the Navy, Air Force, DRDO, and defence PSUs arriving regularly.
Bear case: Several stocks trade at elevated valuations relative to current earnings. Order timing is unpredictable, and a single delayed contract can swing quarterly results significantly. SME names also carry liquidity risk that mainboard investors may not anticipate.
Key Risks to Watch
- Revenue is heavily dependent on government and defence PSU orders, which can slip in timing.
- Several stocks trade at high P/E ratios relative to current earnings.
- SME-listed names have lower liquidity and wider bid-ask spreads.
- Rising receivables and elevated debtor days appear across multiple companies.
- Smaller firms often carry concentration risk linked to a handful of large customers.

Frequently Asked Questions
No stock is risk-free. Small-cap defence names carry additional volatility arising from order-driven revenue, high valuations, and (in some cases) thin SME liquidity. Thorough fundamental research is essential before investing.
SME stocks trade on a separate platform with lower liquidity, larger lot sizes, and generally fewer disclosure requirements than mainboard stocks. Price swings tend to be sharper.
Avantel and Taneja Aerospace have declared dividends in recent quarters. Most of the other names, particularly the newer SME listings, do not currently pay dividends.
Higher capital expenditure and indigenisation rules generally support more domestic orders. However, budget allocation does not guarantee order timing, so revenue can remain lumpy from quarter to quarter.
