Aerospace Component Manufacturing & MRO
Forgings, composites, landing gear and engine components - and the MRO hangars that keep fleets flying
What this is
- Forgings and castings feed precision structures, engines and landing gear.
- Avionics are designed in, and primes assemble finished platforms.
- Every platform then comes back for decades of maintenance (MRO).
Why now
- Global plane makers are diversifying sourcing beyond China.
- Indian defence programmes (Tejas, engine localisation, drones) are ramping up at the same time.
What to watch
- New OEM qualification wins and order-book disclosures
- Capacity/foundry expansion announcements
- Defence platform programme milestones (Tejas, C-295, engine JVs)
- Civil MRO capacity additions and hangar announcements
- Global OEM China+1 sourcing allocations to India
Major areas
The map groups the anatomy into these areas before you drop into individual components.
Materials & Forgings
Raw titanium, superalloy and special-alloy forgings and castings that feed every structural, engine and landing-gear component maker downstream.
Structures & Landing Systems
Machined structural parts, composite aerostructures and the undercarriage/actuation systems that make up the physical airframe.
Engine & Propulsion
Turbine/compressor blades and hot-section forgings that go into the jet engines and gas turbines powering the aircraft.
Avionics & Mission Systems
Radar, avionics, EW and mission electronics designed into the cockpit, nose and mission bays.
MRO & Sustainment
Hangars and repair lines that maintain, overhaul and life-extend aircraft, engines and components across their operating life.
Systems Integration & Primes
The primes that integrate structures, engines and electronics into a complete flying platform and deliver the finished aircraft or system.
End manufacturers & integrators
The companies that assemble the finished product from everything else in this chain — systems integration, assembly EPC & primes.
