Picture the inside of a modern fighter jet, a transport aircraft or a satellite programme — not the gleaming airframe, but the nervous system tucked behind the panels: kilometres of wiring, carefully routed, tested and connected so that power, data and signals reach exactly where they are needed, every single time. That hidden, high-stakes work is what Bengaluru-based Rossell Techsys has spent 15 years mastering, and it has just given itself a much bigger home in which to do it.
Inside Rossell Techsys’s Bengaluru facility, where technicians build wiring systems for aerospace and defence programmes.
A second Bengaluru factory, three minutes from the first
On 2 November 2026, Rossell Techsys inaugurated a new 210,000 sq ft facility in Bengaluru, marking 15 years in business. The company says the new site will strengthen its manufacturing capacity to meet evolving customer requirements and support its next phase of growth. It sits in the same industrial park as the company’s existing 225,000 sq ft facility in Bengaluru’s Aerospace Defence Park, a few minutes away — effectively doubling the footprint from which Rossell Techsys serves the world’s aerospace and defence industry.
Rossell Techsys describes itself as a provider of high-reliability engineering and manufacturing solutions to global aerospace and defence original equipment manufacturers (OEMs). Today, the company says, it serves more than 30 global customers. Its work spans aerospace and defence, and it is now extending the same discipline into space programmes and semiconductor manufacturing, while a recently acquired maintenance, repair and overhaul (MRO) licence opens up the aviation aftermarket as well.
The wiring, panels and test systems behind global platforms
At the heart of Rossell Techsys’s work is the electrical wiring interconnection system — EWIS for short. The company builds high-complexity power, radio-frequency, control, data and signal harnesses, integrated with active and passive components, along with integrated electrical panels and fibre optics. Around that core, it offers electronic assemblies and a full range of test solutions and system integration, from design, prototyping and testing through installation, commissioning, repair and end-of-life support.

That is build-to-specification and build-to-print work at its most demanding: every harness and panel is made to a customer’s exact design, in low volumes and high complexity, where a single fault is not an option. The company says its centres of excellence, adaptability to customer processes and rigorous quality systems are what have kept global OEMs coming back — and what its new capacity is built to scale.
A Boeing relationship that began in 2013
Nowhere is that trust clearer than in Rossell Techsys’s long-standing relationship with Boeing, which the company says began in 2013 with a single platform and has since expanded to cover almost all of Boeing’s defence platforms. In September 2025, the company signed a long-term contract with Boeing to manufacture electrical panel assemblies for the T-7A Red Hawk, Boeing’s advanced pilot training system, under which it can produce up to 1,200 shipsets through 2033. The company says it has been associated with the T-7A programme since its engineering and manufacturing development and early flight-test stages, building on an earlier contract for wire harness assemblies for the same aircraft.
Beyond the T-7A, the company says its work touches several of Boeing’s major defence platforms, including the F/A-18 Super Hornet, F-15 Eagle, AH-64 Apache, CH-47 Chinook, V-22 Osprey, P-8 Poseidon and KC-46 Pegasus. The company says it has delivered more than 160,000 critical assemblies to Boeing, and that its consistent performance has been recognised with two Boeing Supplier of the Year awards. Its customer list also includes Lockheed Martin, Honeywell and other global OEMs, alongside Indian organisations such as HAL, BEL and the Indian Air Force.
Building the workforce behind the factory
A factory is only as good as the people inside it, and Rossell Techsys has invested in that side of the story too. Through the Boeing Kaushal Program, the company says it has contributed to India’s aerospace talent ecosystem since 2014, with nearly 95% employment continuity and 100% absorption for its most recent graduating cohort. The programme also promotes inclusive employment, including opportunities for specially abled talent.
Managing director Rishab Gupta said the 15-year journey reflects the trust customers have placed in the company and its commitment to evolving with the industries it serves. “From our roots in aerospace and defence to our growing presence in emerging sectors, we have continued to build on our experience while staying true to our philosophy of ‘Transforming While Performing’,” he said. “The inauguration of this facility marks an important milestone in this journey and reinforces our commitment to building lasting partnerships and creating long-term value.”
That commitment has also earned external recognition: Rossell Techsys was recognised as the ET Edge Best Manufacturing Brand 2026 and among the ET Edge Best Organizations to Work 2026. With a new 210,000 sq ft facility, a growing space and semiconductor business and a new MRO arm, the Bengaluru maker that wires the world’s aircraft is now building the capacity to take on considerably more of them.
