Engine Supply and Production Roadmap

India is proactively addressing engine supply challenges and scaling up indigenous production for current and future Tejas variants.

The HAL Tejas Story—Innovation, Power & Export Potential » DefenceXP - Indian Defence Network.pdf

F404 Engine Supply for Mk-1A

Engine delivery for Tejas Mk-1A is back on track, with GE supplying two F404 engines per month until March 2026 to support current production.

The HAL Tejas Story—Innovation, Power & Export Potential » DefenceXP - Indian Defence Network.pdf

F414 Engine Co-production for Mk-2/AMCA

HAL and GE Aerospace signed an MoU in June 2023 to jointly manufacture F414 engines in India with up to 80% Transfer of Technology (ToT).

The HAL Tejas Story—Innovation, Power & Export Potential » DefenceXP - Indian Defence Network.pdf

F414 Cost

GE F414 engines for Tejas Mk-2/AMCA cost $9–10 million per unit, reflecting higher thrust and newer technology.

The HAL Tejas Story—Innovation, Power & Export Potential » DefenceXP - Indian Defence Network.pdf

Local Production Timeline

HAL is preparing a new production plant near Bangalore, operational in about two years, with first indigenous F414 deliveries targeted by mid-2028.

The HAL Tejas Story—Innovation, Power & Export Potential » DefenceXP - Indian Defence Network.pdf

Planned Production Rates

Initial production rate of one engine per month will scale to two engines per month, supporting roughly 24 Tejas Mk2 aircraft annually by 2030–31.

The HAL Tejas Story—Innovation, Power & Export Potential » DefenceXP - Indian Defence Network.pdf

Long-Term Production

Long-term projections indicate over 400 F414 engines could be produced in India for Tejas Mk-2, TEDBF, and AMCA Mark-1.

The HAL Tejas Story—Innovation, Power & Export Potential » DefenceXP - Indian Defence Network.pdf

Long-Term Security via Indigenization

Tejas Mk-2/AMCA (F414 local production) ensures long-term security via indigenization, making it insulated from tariffs and most supply-chain shocks.

The HAL Tejas Story—Innovation, Power & Export Potential » DefenceXP - Indian Defence Network.pdf

Engine Agreement Resilience

The GE-HAL engine agreement is strategic, involves existing orders, and represents long-term industrial cooperation, making it resilient to tariffs.

The HAL Tejas Story—Innovation, Power & Export Potential » DefenceXP - Indian Defence Network.pdf

Engine Supply Risk Matrix (2025-2030)

A risk matrix compares supply risks for Tejas Mk-1A (F404 imports) and Tejas Mk-2/AMCA (F414 co-production) across various factors.

The HAL Tejas Story—Innovation, Power & Export Potential » DefenceXP - Indian Defence Network.pdf

Factor	Tejas Mk-1A (F404 imports)	Tejas Mk-2/AMCA (F414, co-production)	Risk Level
Tariffs on U.S. aerospace exports	Raises per-engine cost (short-term, import dependent); HAL may absorb or renegotiate.	Minimal exposure, engines produced in India under ToT; tariffs largely irrelevant.	High risk (Mk-1A) / Low risk (Mk-2/AMCA)
Existing Contracts	Binding contracts for 97 additional Tejas Mk-1A; deliveries restarted July 2025.	Strategic ToT & JV agreements with HAL-GE for 80% local content production.	Stable (both)
Supply Chain Bottlenecks	Vulnerable F404 line was dormant, restart caused delays (Korean supplier bottleneck); any hiccup could delay batches.	Better resilience, new line in India builds long-term redundancy; local supplier ecosystem to be created.	Medium (Mk-1A) / Low (Mk-2/AMCA)
Cost Escalation	Tariffs + supply issues could increase program cost for IAF.	Local production reduces forex outflow and tariff risk; upfront JV investment required.	Moderate (Mk-1A) / Low (Mk-2/AMCA)
Political / Strategic Risk	Low - U.S. unlikely to block F404 supplies given strategic partnership.	Very low - F414 co-production is centerpiece of Indo-U.S. defense ties.	Low (both)

Export Market Potential and Strategy

Tejas has moderate short-term export potential, with stronger prospects for Mk-2 and beyond if supported by co-production and marketing.

The HAL Tejas Story—Innovation, Power & Export Potential » DefenceXP - Indian Defence Network.pdf

Tejas as Attractive Export Option

Tejas is an attractive export option due to its cost-effectiveness, absence of geopolitical restrictions, and India's offer of customized support and technology transfers.

A risk matrix compares supply risks for Tejas Mk-1A (F404 imports) and Tejas Mk-2/AMCA (F414 co-production) across various factors.

The HAL Tejas Story—Innovation, Power & Export Potential » DefenceXP - Indian Defence Network.pdf

Factor	Tejas Mk-1A (F404 imports)	Tejas Mk-2/AMCA (F414, co-production)	Risk Level
Tariffs on U.S. aerospace exports	Raises per-engine cost (short-term, import dependent); HAL may absorb or renegotiate.	Minimal exposure, engines produced in India under ToT; tariffs largely irrelevant.	High risk (Mk-1A) / Low risk (Mk-2/AMCA)
Existing Contracts	Binding contracts for 97 additional Tejas Mk-1A; deliveries restarted July 2025.	Strategic ToT & JV agreements with HAL-GE for 80% local content production.	Stable (both)
Supply Chain Bottlenecks	Vulnerable F404 line was dormant, restart caused delays (Korean supplier bottleneck); any hiccup could delay batches.	Better resilience, new line in India builds long-term redundancy; local supplier ecosystem to be created.	Medium (Mk-1A) / Low (Mk-2/AMCA)
Cost Escalation	Tariffs + supply issues could increase program cost for IAF.	Local production reduces forex outflow and tariff risk; upfront JV investment required.	Moderate (Mk-1A) / Low (Mk-2/AMCA)
Political / Strategic Risk	Low - U.S. unlikely to block F404 supplies given strategic partnership.	Very low - F414 co-production is centerpiece of Indo-U.S. defense ties.	Low (both)
