What Sika Interplant Systems does

Sika Interplant Systems Limited is a publicly listed Indian aerospace and defense engineering company (BSE code: 523606) headquartered in Bangalore, operating across the Aerospace, Defence & Space (A&D) and Automotive sectors. The company's platform is organized around four business lines: engineered projects and systems (including dipping sonar winches for anti-submarine warfare, landing gear assemblies, and handling systems); interconnect solutions and electrical module integration (cable assemblies, wiring harnesses, electro-mechanical assemblies, and electronic LRU integration); maintenance, repair and overhaul (MRO) services; and value-added distribution of international OEM products. Sika is the only company in South Asia to have developed helicopter-borne dipping sonar winches for anti-submarine warfare, and through its Aerotek Sika joint venture with Aerotek Aviation Engineering Ltd (UK), operates the first and only dedicated private-sector landing gear facility in India.

The company's underlying technology integrates hydraulics, electro-mechanics, and electronics across aerospace-qualified products manufactured and tested to AS 9100D, MIL-STD, CEMILAC, and EASA standards. Sika maintains a 6.5-acre Sika Technology Center campus in Bangalore with 48,000 sq.ft. of assembly, integration, testing, MRO, and inspection facilities, plus a newly constructed 21,000 sq.ft. Grade A expansion building and a 22,500 sq.ft. Aerotek Sika landing gear plant. Exclusive distribution and authorized service center agreements with international OEMs — including Breeze-Eastern (rescue hoists and cargo hooks), LMB France (aerospace fans/blowers), Fives Filling & Sealing (automotive fluid filling since 1997), Radiant Power Corp, and motion control and fluid control component manufacturers — provide additional revenue streams and India-market access for global aerospace suppliers.

Sika generates revenue through a combination of project-based, multi-year fixed-price turnkey contracts for complex aerospace and defense systems, hardware sales of interconnect solutions and distributed OEM products, professional services for MRO, and licensing/royalties from software distribution. The company serves primarily Indian government customers including the Ministry of Defence, HAL, Indian Military, and Indian Navy, with go-to-market executed through direct enterprise field sales, participation in major trade shows (Aero India, Paris Airshow, DSEI), and authorized service center channels. Five subsidiaries and one joint venture (Aerotek Sika) extend the operating perimeter into landing gear MRO, aviation systems, and adjacent engineering services.

Broad incumbents

• Hindustan Aeronautics Limited (HAL): India's largest state-owned aerospace and defense manufacturer — a key customer of Sika for landing gear, MRO and particle separators, but also a much broader incumbent operating across aircraft platforms, engines and systems. Relevant as both customer and macro benchmark.
• Bharat Electronics Limited (BEL): Large Indian state-owned defense electronics company supplying radars, communications, EW, avionics and electronic systems to the Indian armed forces. A broader incumbent in the same Indian defense electronics space where Sika operates, but with a much larger portfolio and PSU scale.
• Bharat Dynamics Limited (BDL): Indian state-owned manufacturer of guided missiles, underwater weapons and allied defense equipment for the Indian armed forces. Relevant broad incumbent given Sika's anti-submarine warfare dipping sonar exposure to the Indian Navy.
