Quick Answer

SIDA Defence Expo 2026 takes place on 25–26 September 2026 at Rathinam Grand Hall, Pollachi Main Road, Coimbatore, from 10:00 AM to 6:00 PM daily. It is South India’s dedicated defence manufacturing, aerospace, and dual-use technology exhibition, organized by the South Indian Defence Suppliers and Startups Association (SIDA) to advance India’s Atmanirbhar Bharat (self-reliance) mission. Visitor entry is free; delegates can book a VIP pass online via Online. The expo covers 10 focus sectors — from UAVs and AI to cybersecurity and precision engineering and connects MSMEs, startups, and engineering firms directly with defence PSUs, DRDO, and tier-1 contractors.

What Is the SIDA Defence Expo 2026?

The SIDA Defence Expo 2026 is India’s premier South Indian defence, aerospace, and security exhibition, hosted in Coimbatore, Tamil Nadu. Organized by the South Indian Defence Suppliers and Startups Association, the event is built around a simple but powerful idea: India’s defence self-reliance won’t be achieved by a handful of national giants alone it depends on the thousands of MSMEs, engineering workshops, and startups scattered across the South Indian manufacturing corridor.

Unlike the mega international defence expos that primarily court global prime contractors, SIDA Defence Expo 2026 is deliberately regional and inclusive. Its stated goal “building a stronger, self-reliant India” translates into practical, on-ground access for smaller manufacturers who want to pivot into defence-grade production but don’t know where to start.

Over two days, 25–26 September 2026, the expo brings together defence Public Sector Undertakings, DRDO representatives, tier-1 contractors, startups, and engineering firms under one roof at Rathinam Grand Hall.

Dates, Timing & Venue

• Dates: Thursday 25 September – Friday 26 September 2026
• Timing: 10:00 AM to 6:00 PM on both days
• Venue: Rathinam Grand Hall, Pollachi Main Road, Coimbatore, Tamil Nadu

Coimbatore’s selection as the host city is strategic. The region already has an established base of precision engineering, textile, and automotive component manufacturers industries the expo specifically targets for diversification into defence-grade manufacturing.

Focus Sectors Covered at the Expo

SIDA Defence Expo 2026 is organized around ten focus areas, giving visitors and exhibitors a clear map of where opportunity lies:

1. Defence Manufacturing — core production and component supply
2. Aerospace Technologies — components, systems, and MRO capability
3. UAV & Drone Systems — a fast-growing segment covered in dedicated Day 2 sessions
4. Defence Electronics — sensors, communication, and embedded systems
5. Artificial Intelligence — AI in modern defence operations, a headline Day 2 workshop
6. Robotics & Automation — unmanned ground systems and automated manufacturing
7. Cyber Security — protecting digital defence infrastructure and info-warfare readiness
8. Precision Engineering — high-tolerance manufacturing for defence-grade parts
9. Textile — technical and ballistic textiles for defence applications
10. Export Opportunities — pathways for Indian manufacturers into global defence supply chains

This breadth means the expo isn’t limited to traditional “defence” companies. Automotive component makers, textile mills, electronics assemblers, and software/AI teams all have a realistic entry point.

How to Register: Visitors vs Delegates

Visitors get free exhibition-hall access for both days, including direct interaction with 200+ exhibitors and an Innovation Hub focused on MSMEs and startups. Spot registration is available exclusively at the venue, but pre-registering online is recommended to skip queues.

Delegates seeking deeper access — VIP networking, priority seating at panels, and closer engagement with PSU and DRDO representatives can book a paid VIP pass through on the expo’s registration.

Why MSMEs and Startups Should Attend

If your business operates in engineering, automotive, textiles, or electronics, this expo is positioned as a direct pathway into defence-grade production. Attendees get face-to-face access to defence PSUs and DRDO representatives, learn actual vendor registration and certification requirements, and can access subsidized stall pricing if registered as an MSME or Startup India-certified entity. While contracts aren’t signed on the show floor, the procurement knowledge gained here is often the missing link between a civilian manufacturing unit and its first defence supply contract.

Why Exhibiting Makes Commercial Sense

Booking a stall puts your company in front of defence procurement officers, tier-1 contractors, and policymakers actively scouting reliable subcontractors. Combined with subsidized MSME/Startup pricing, the cost-to-visibility ratio is difficult to match at larger national-scale defence expos where smaller vendors get lost in the noise.
