Aerospace & defencemanufacturing, MRO, India indigenisation

Commercial aerostructures and engines, defence platforms (aircraft, missiles, ammunition, naval), precision components (castings, forgings, machining) and maintenance, repair & overhaul (MRO). A record ~17,000-aircraft commercial backlog (~12 years of output) is throttled by castings/forgings and engine supply; European rearmament (ReArm Europe, ~EUR 800bn) and India's indigenisation (defence production INR 1.78 lakh cr in FY26, exports INR 38,424 cr) drive new plant capex in ammunition, missiles, electronics and MRO.

How Capibud uses this pack

A pack is a starting position, not a forecast. When a aerospace & defence decision opens in Capibud, pack v1.0.0 is copied in and pinned to that decision. The 15 parameters, 9 swing factors and templates the committee saw stay attached to the decision record, even after the pack is next refreshed.

Parameter ranges and WBS durations seed the P50, P80 and P90 for capex, schedule and value. Your own estimates, vendor quotes and actuals replace pack defaults line by line, and the record shows which numbers are still defaults.

Each swing factor is wired to shared factors; here the heaviest are policy, labour, electrical equipment and steel. A move in one factor hits every exposed project in the same scenario, which is how the capital committee sees concentration across a book rather than project by project.

The 7 price feeds and 20 listed tickers feed the brain, which watches for drivers moving outside their pack range and drafts the change for a person to review.
