This is a first-principles primer, not a broker initiation note with an industry preamble bolted on front. The order is deliberate: the physical and regulatory reasons a part is hard to make come first; every commercial fact that follows — margin, order book, valuation — is presented as a consequence of that difficulty, not as a separate story. If you finish Sections 1–4 and cannot explain why a landing- gear bracket and a cabin bracket cost ten times apart despite being the same metal, the primer has not done its job yet.
Cutting a piece of titanium to the right shape is a scaling problem: buy the machine, hire the operator, hit the tolerance. Proving that the same piece of titanium will survive thirty years of flight, and documenting that proof to a stranger's satisfaction, is a different kind of problem entirely — and it is the one almost no published statistic about "India's aerospace opportunity" actually measures. Every company report in this document is really answering one question: how far up that second, harder ladder has this company actually climbed, versus how far the story about it has climbed.
A note on sourcing: every figure in this report carries a source and a date next to it. Where published estimates disagree — and in this sector they disagree often — we show the disagreement rather than picking a number silently. Where we could not verify something, we say so. See the closing Notes section for the full methodology and data caveats.
