2026-07-15 High-bypass turbofan design and integrationNo capability · No indigenous high-bypass turbofan exists in India; all commercial and large transport aircraft depend entirely on foreign engines or licensed assembly. status
2026-07-15 Military turbofan engineEmerging · The dry Kaveri variant is in flight-testing certification phase with Godrej delivering limited serial production units (D1 September 2025, D2-D3 Q1 2026); the full-thrust afterburning variant passed a full-burner test in February 2026 but remains pre-operational and heavily import-dependent overall. status
2026-07-15 High-temperature superalloysEmerging · DMRL has demonstrated single-crystal blade casting capability at limited scale; MIDHANI and Aerolloy are establishing production facilities; no indigenous high-temperature superalloy engines fielded. status
2026-07-15 Carbon-fibre composite manufacturing for large aero structuresEmerging · India has demonstrated prototype and small-series CFRP manufacturing for aerospace components (wings, fuselage sections) and operates research facilities producing standard-modulus carbon fibre, but no large-scale commercial production of primary aerostructures and zero indigenous carbon fibre precursor capacity. status
2026-07-15 Quadruplex redundant flight control computer hardwareDemonstrated · India has successfully designed, built, and certified a quadruplex digital flight control computer for the HAL Tejas LCA, which is in operational service with the Indian Air Force; however, production remains limited to domestic platforms and has not achieved competitive export presence or industrial-scale manufacturing. status
2026-07-15 Real-time flight-certified sensor suiteEmerging · GTRE has integrated sensors for ground and altitude testing of Kaveri; infrastructure for flight testing (flying testbeds, NAETC) planned but not yet operational; no flight-certified indigenous suite in service. status
2026-07-15 Flight management systemEmerging · HAL and DRDO developing avionics subsystems (flight control, mission computers, displays) integrated into aircraft like Tejas, but no standalone indigenous FMS product for commercial or military scale deployment. status
2026-07-15 Vacuum investment castingDemonstrated · DMRL has delivered functional single-crystal HPT blade castings (60 units to HAL in 2021, ongoing vane production in 2024), meeting airworthiness certification, but production scale remains limited to research quantities and machining capability remains outsourced. status
2026-07-15 Reusable thermal protection systemDemonstrated · ISRO successfully flight-tested RLV-TD with ~600 indigenous heat-resistant tiles in 2016, exposed to hypersonic reentry; RLV-ORV program aims orbital-scale validation by 2027–28, but production maturity and multi-flight durability not yet established. status
2026-07-15 Electro-hydraulic flight control actuatorsDemonstrated · India has demonstrated indigenous secondary electro-hydraulic servo-actuators (leading-edge slats and airbrakes) for Tejas Mark 1A with successful flight trials completed as of April 2024; primary flight control actuators remain in integration testing phase. status
2026-07-15 Digital engine controlDemonstrated · HAL's indigenous FADEC passed ground evaluation and achieved flight test clearance in 2025; DRDO's Kaveri engine incorporated a FADEC derivative (KADECU); but no production deployment on operational fighter aircraft yet. status
2026-07-15 Deep-throttling liquid rocket engineEmerging · CE-20 demonstrates limited throttling (20-22 tonne range); LOX-methane engines in early testing; NGLV programme explicitly requires throttling for landing, but sub-scale tests only just begun in January 2026. status
2026-07-15 DO-178C flight software certification processNo capability · No evidence of indigenous Indian DO-178C certification infrastructure or completed projects; India uses domestic CEMILAC/IMAP certification processes for military airborne systems instead. status
2026-07-15 Aero gas turbine designEmerging · GTRE has working engine prototypes (Kaveri Dry Engine approved for inflight testing Dec 2024; Manik producing small engines in series) but neither has achieved production-scale military certification or operational service. status
2026-07-15 Advanced aluminium alloy melting and rolling processEmerging · HAAL casts aerospace-grade hard alloys; BALCO and NALCO operate rolling capacity but for commodity grades; extrusion press still under foundation (June 2026), rolling for flight-critical 2xxx/7xxx sheet/plate not in production. status
