Multi-Application Drone Manufacturing Facility

Project Overview

An Indian aerospace startup consortium and a European drone navigation technology partner engaged IMARC Engineering to establish a greenfield multi-application drone manufacturing facility within the SAS Nagar (Mohali) Industrial Area in Punjab. The project was structured against the Government of India's PLI scheme for Drones and Drone Components, an INR 120 Crore corpus under which 23 manufacturers were approved across the 2022 application round, and within the broader policy context of the Drone Rules 2021 (which liberalised the Indian drone regulatory framework and introduced the Digital Sky platform), the Namo Drone Didi scheme (an INR 1,261 Crore programme deploying 15,000 drones through women self-help groups for agricultural spraying), the Kisan Drone framework for agricultural applications, and the SVAMITVA property survey programme.

The project involved establishing 12,000 drones per annum across three application segments — agricultural spraying drones for the Namo Drone Didi and Kisan Drone deployment programmes, surveillance and mapping drones for central government and state agency use cases including the SVAMITVA framework, and light logistics drones for the emerging commercial delivery market — with site infrastructure designed for Phase 2 expansion adding heavy-payload logistics drones and counter-drone systems.

Client's Challenges

The client faced several specific challenges in establishing greenfield drone manufacturing in India:

• Multi-application platform complexity: Engineering three distinct drone platforms sharing common frame and avionics architecture while accommodating application-specific payload requirements, chemical spray tanks for agricultural applications, gimballed camera and sensor payloads for surveillance and mapping, and lightweight cargo bays for logistics, within a single flexible manufacturing framework.
• DGCA Type Certification pathway: Securing DGCA Type Certification for each drone class under the Drone Rules 2021 framework, alongside BIS drone standard compliance and integration with the Digital Sky platform for the required unique identification and registration workflows.
• Component supply security: Managing supply of drone-grade brushless DC motors, high-energy-density lithium polymer batteries, flight controllers, GNSS receivers, and payload cameras, categories where specialty imports have historically dominated but where Indian supplier development is progressing under the parallel PLI framework for drone components.
• PLI DVA milestones: Meeting the PLI Drones scheme's Domestic Value Addition milestones over the scheme window, with the incentive of 20 percent of value addition rewarding deliberate localisation across the frame, motors, propulsion, and payload integration scope.
• Government and defence customer qualification: Achieving the qualification frameworks required by central government surveillance agencies, state agricultural departments, and the defence services, each with distinct product acceptance, cybersecurity, and supply-chain-trust requirements.
• Workforce build-up: Recruiting 260 personnel including drone systems engineers, avionics integration specialists, and skilled assembly technicians in the SAS Nagar and Chandigarh Tricity technology talent ecosystem that also serves the surrounding electronics and IT industry.

What We Did

• Pre-Investment and Strategic Advisory

Our feasibility study evaluated four candidate locations in India: SAS Nagar Mohali (Punjab), Bengaluru Electronic City Extension (Karnataka), Hyderabad Aerospace Park (Telangana), and Coimbatore (Tamil Nadu). Mohali was selected as the preferred location. The decision was based on the strength of the SAS Nagar-Chandigarh Tricity technology ecosystem, including STPI Mohali, Semiconductor Laboratory Mohali, and the broader electronics manufacturing supplier base.

The location also offers proximity to customer procurement offices in Delhi-NCR and Chandigarh International Airport. In addition, the Punjab Industrial and Business Development Policy 2022 provides attractive incentives. Access to engineering talent from Punjab Engineering College and neighbouring institutions further strengthened Mohali's position.

CapEx planning of INR 232 Crore covered the airframe fabrication and assembly halls, the avionics and electronics assembly area, the payload integration zone, the flight test area, the warehouse, and central utilities, with cumulative PLI eligibility of approximately INR 26 Crore modelled across the scheme window. Financial modelling demonstrated post-tax IRR of 22.4 percent at full ramp with a 5.2-year payback.

• Engineering and Design Services

IMARC designed a 14,000 sq.m built-up facility on a 6-acre plot. The facility includes an airframe fabrication and assembly hall for composite frame lay-up and machining. It also features an avionics and electronics assembly area equipped with Surface Mount Technology (SMT) and Automated Optical Inspection (AOI) systems for manufacturing flight controllers and telemetry boards. A dedicated payload integration zone accommodates agricultural spray systems, gimballed cameras, sensor assemblies, and light logistics cargo bays. The facility also includes an on-site flight test area for airworthiness validation, along with a warehouse and logistics block.

Process utility design covered 3 MW grid demand supplemented by a 0.8 MW captive rooftop solar array, ESD-controlled environment throughout the electronics assembly zones, controlled temperature and humidity HVAC for the composite lay-up and electronics areas, and integrated MES for lot traceability aligned with the aviation-grade recall management requirements.

• Procurement and Supply Chain Support

We executed a multi-geography procurement programme across 42 critical vendors. Composite fabrication equipment for the frame lay-up scope was sourced from European specialists with documented aerospace-grade references. Surface Mount Technology and electronics assembly equipment for the flight controller manufacturing was sourced from Japanese and German specialists. Payload integration test equipment was sourced from a combination of European and Indian specialists.

Component sourcing was structured to progress PLI DVA over the scheme window: composite frame materials and airframe hardware from Indian aerospace-grade suppliers, brushless DC motors from Indian and international specialists, lithium polymer battery packs from Indian battery assemblers under structured technology partnerships, flight controllers assembled in-house on locally-sourced PCBs, GNSS receivers and specialty payload cameras from European and East Asian suppliers under long-term agreements. PLI DVA reached 42 percent in Year-1 operations and 48 percent in Year-2.

• Project Execution and Site Management

Our turnkey project management delivered 18 months from groundbreaking to first commercial delivery, coordinating civil construction, mechanical and electrical erection, ESD-controlled environment fit-out, equipment integration, and phased commissioning across the airframe, avionics, and payload integration zones.

Phased commissioning ran the airframe fabrication line first, followed by the avionics and electronics assembly area, then the payload integration zone, and finally the on-site flight test area with DGCA-supervised Type Certification test flights across the three drone classes. Multi-vendor coordination across European, Japanese, and Indian contractors required a 12-strong owner's engineering team supplemented by 6 European resident engineers from the technology partner during the avionics commissioning and first flight test campaigns.

• Compliance, Quality and Sustainability

IMARC led certification readiness across DGCA Type Certification under the Drone Rules 2021 framework — secured across the three drone classes in Year-1 of commercial operations — BIS drone standard compliance, Digital Sky platform registration and unique identification workflow integration, ISO 9001:2015 quality management, AS9100D aerospace quality management system alignment for the defence and surveillance product family, and customer-specific supplier audit frameworks for central government surveillance agencies.

Environmental compliance covered Punjab Pollution Control Board Consent to Establish and Operate, Hazardous Waste Authorisation for composite manufacturing residues and end-of-life battery management, and Extended Producer Responsibility commitments for the lithium polymer battery lifecycle. The facility achieved IGBC Gold certification through 0.8 MW captive rooftop solar covering approximately 21 percent of facility daytime energy demand, 66 percent process water reclamation, and 16 percent lower facility energy intensity versus the Southeast Asian drone manufacturing industry benchmark.

Final Results

Operational Performance

The facility achieved mechanical completion in 18 months with first commercial delivery in month 19. Full 12,000-unit per annum nameplate capacity was reached at 78 percent utilisation by month 15 of operations, with sustained first-pass yield of 97.4 percent across the drone product portfolio.

DGCA Type Certification was secured across the three drone classes in Year-1, BIS drone standard compliance was completed, and successful supplier qualification audits were passed with central government surveillance agencies, state agricultural departments under the Namo Drone Didi framework, and two commercial mapping customers.

Financial Outcomes

Final CapEx of INR 220 Crore delivered 5.2 percent savings against the INR 232 Crore budget through optimised civil packaging, disciplined Indian-fabrication leverage across the composite frame and structural scope, and multi-vendor procurement under the PLI DVA framework.

PLI Drones disbursements commenced from Year-1 commercial production against the scheme's value-addition-based structure, with cumulative scheme benefit of approximately INR 26 Crore modelled across the scheme window. Year-2 revenue of INR 370 Crore was generated at an EBITDA margin of 13 percent, consistent with established Indian drone manufacturer reporting.

Market Access

Supply commitments were signed across the three drone application segments — agricultural spraying drones supplied under the Namo Drone Didi deployment programme via partnering women SHG cooperatives and the Kisan Drone framework via state agricultural departments, surveillance and mapping drones supplied to central government surveillance agencies and to state agencies under the SVAMITVA property survey programme, and light logistics drones supplied to commercial mapping and infrastructure inspection customers.

Export share reached 22 percent of revenue by Year-2 through entries into Southeast Asian and African agricultural drone markets, with the Middle East surveillance drone market identified as the Phase 2 export expansion target.

Sustainability Impact

Our integrated design — combining 0.8 MW captive rooftop solar covering approximately 21 percent of facility daytime energy demand, closed-loop composite manufacturing offcut recovery, variable-frequency drives across HVAC and process systems, and LED lighting throughout — achieves 16 percent lower facility energy intensity versus the Southeast Asian drone manufacturing industry benchmark.

Process water reclamation reaches 66 percent through closed-loop cooling and cleaning cycles. The facility holds IGBC Gold certification and operates end-of-life drone and battery take-back partnerships with the supplied customer base, aligned with the Extended Producer Responsibility framework for lithium polymer batteries under the Battery Waste Management Rules 2022.

Strategic Impact

The project established a meaningful greenfield multi-application drone manufacturing capability under the PLI Drones and Drone Components framework, positioned across the three highest-growth Indian drone application segments, agriculture, government and defence surveillance, and commercial mapping and light logistics.

Year-2 revenue of INR 370 Crore, three DGCA Type Certifications secured, and government-programme customer qualifications established led the client to approve Phase 2 expansion comprising heavy-payload logistics drones aligned with the emerging commercial delivery market and counter-drone systems for the defence sector.

IMARC Engineering's end-to-end EPCM advisory, combining drone platform and payload engineering, DGCA Type Certification pathway support, PLI Drones scheme navigation, and Digital Sky platform integration readiness, enabled the client to anchor a strategically important Indian aerospace industrial asset in an emerging sector where regulatory pathway navigation and multi-customer qualification complexity have historically raised the entry barrier for first-time drone manufacturers.
