2026-07-15 Laser-produced tin-plasma EUV light sourceNo capability · No Indian entity or programme attempting development; technology entirely imported via ASML's global monopoly. status
2026-07-15 Turboprop engineEmerging · HAL is adapting existing helicopter turboshaft engines into turboprop variants for UAVs and conducting local assembly of imported engines, but no full-cycle indigenous turboprop design is in production. status
2026-07-15 Aerospace-grade aluminium alloys and CFRP compositesEmerging · Hindalco-Almex manufactures aerospace-grade aluminium alloys at scale (12,000 TPA); CFRP component manufacturing exists but India fully imports raw carbon fibre; major investments announced by Reliance and Jindal remain in development/early production phases. status
2026-07-15 Integrated commercial avionics suiteEmerging · R&D exists in military avionics components through BEL/DRDO/HAL, but no integrated commercial avionics suite has been completed or certified for civilian use. status
2026-07-15 Large-aircraft final assembly lineDemonstrated · India has successfully assembled and test-flown indigenous C-295 aircraft and inaugurated two operating FALs, but remains dependent on foreign OEM partnership and design. status
2026-07-15 Wide-chord composite fan bladesNo capability · No evidence of indigenous Indian capability; India imports all aero-engine fan blades and depends entirely on foreign suppliers. status
2026-07-15 Process integration and yield engineering expertiseEmerging · India has government-backed fab projects underway with international technology partners (PSMC, equipment vendors) and academic training programs launching, but no independent operational fab demonstrating indigenous process integration capability yet. status
2026-07-15 GaN RF semiconductorDemonstrated · DRDO achieved prototype GaN MMIC devices by March 2023 and demonstrated MMICs with 40W power at X-band frequencies; Agnit moved to initial wafer production in 2022; no large-scale commercial RF manufacturing yet operational. status
2026-07-15 MOCVD reactor equipmentNo capability · No evidence of indigenous MOCVD reactor equipment manufacturing in India; academic labs import foreign equipment; Taiyo Nippon Sanso has supply presence only, not manufacturing. status
2026-07-15 Compound semiconductor wafer fabEmerging · First commercial SiC fab (SiCSem) under construction with August 2025 government approval; DRDO lab demonstrations of GaAs/GaN/SiC; no production-scale manufacturing yet operational. status
2026-07-15 Vacuum induction melting and remeltingDemonstrated · MIDHANI has achieved CEMILAC certification for VIM-produced superalloys (March 2026) and delivered certified cast sticks to HAL, but production remains limited and downstream processes (VAR/ESR) are less developed domestically. status
2026-07-15 Large marine diesel engineEmerging · A government-funded R&D programme with Kirloskar Oil Engines (announced April 2025) is developing a 6 MW prototype with >50% indigenous content, targeting delivery by April 2028; no production scale capability yet exists. status
2026-07-15 Indigenous avionics-grade microprocessorEmerging · SHAKTI 64-bit RISC-V aerospace chip successfully booted in Feb 2025 by IIT Madras & ISRO, but remains in prototype/demonstration phase; no production aircraft avionics systems use indigenous core processors. status
2026-07-15 SiC substrate manufacturingEmerging · SiCSem and RIR Power Electronics have government approval and funding; SiCSem groundbreaking occurred November 2025, RIR targeting epitaxy by December 2025, but neither has yet begun production at scale. status

2026-07-15 Process 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
2026-07-15 GaN 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
2026-07-15 Full-scale flight test & certification infrastructureEmerging · 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
2026-07-15 Aerostructure composite manufacturingProducing · 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
2026-07-15 Aerospace-grade superalloy & titanium manufacturingDemonstrated · 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
