2026-07-15Process design kit (PDK) → Emerging · India has launched a silicon photonics PDK (April 2026) and operates an SCL 180nm PDK, but both are narrowly scoped; full competitiveness requires PDKs for multiple technology nodes and commercial-grade production readiness.status
2026-07-15GaN epitaxial growth (MOCVD) → Emerging · India has demonstrated prototype GaN HEMT design and small-volume device production via DRDO/GAETEC, plus one pre-commercial Crystal Matrix project approved for foundry services, but no production-scale MOCVD epitaxy facility operational domestically.status
2026-07-15Full-scale flight test & certification infrastructure → Emerging · India has operational flight-test centers (National Flight Test Centre, HAL facilities) supporting existing programmes like Tejas, and is actively building new integrated centres (Puttaparthi AIFTC) for next-gen aircraft, but certification processes remain dependent on external expertise.status
2026-07-15Aerostructure composite manufacturing → Producing · HAL, NAL, and private firms manufacture composite aerostructures for Tejas at real scale; L&T delivers composite wings, centre fuselages are produced with indigenous processes (Carbon-BMI), and systems like DRDO's quartz-composite radome are in production validation.status
2026-07-15Aerospace-grade superalloy & titanium manufacturing → Demonstrated · Working domestic production exists—MIDHANI delivers certified superalloys to HAL (March 2026); PTC/Aerolloy operates world's largest single-site titanium plant (6,000 t/a capacity, October 2025)—but at modest volumes and untested at full commercial scale against global competitors.status
2026-07-15High-pressure compressor aerodynamics → Emerging · DRDO has demonstrated HPC drum forging capability and component manufacturing, but full aerodynamic design and multi-stage transonic compressor performance remain unproven at combat engine scale; AHTCE HPC trials now underway.status
2026-07-15High-altitude engine test facility → Emerging · A 130 kN ground test facility nearing completion at Rajankunte (expected operational by October 2025) but lacks full high-altitude altitude-simulation capability; National Aero Engine Test Complex (NAETC) announced March 2026 as planned future facility with high-altitude component.status
