What is the difference between F404 and F414 engine?
As compared to its predecessor F404, F414 also promises significant improvements in aircraft performance, survivability and payload. Built with extra durability technologies, the F414 features 3d aerodynamics, an improved high pressure turbine, and an advanced cooling system (16 percent more airflow than the F404 fan). The question is not whether Tejas is better than MiG-21, it’s whether it is fully operational. That, only the present Air Chief can answer, he said, pointing out that Tejas has better airframe, engine, and avionics.Summary. While both aircraft serve as light multirole fighters, Tejas Mk2 outperforms the J-17 in engine power, payload, avionics, stealth features, and indigenous upgrade potential.The F404-IN20 is a proven, high-performance engine known for its reliability and is a critical component for the Light Combat Aircraft (LCA) Tejas Mk1A variant, which features enhanced avionics and combat capabilities compared to earlier versions.Engine and Performance Tejas Mk2 is powered by the GE F414‑INS6 engine, producing about 98 kN of thrust with afterburner and capable of reaching Mach 1. The F‑16 Block 50/52 typically uses the GE F110‑GE‑129 or Pratt & Whitney F100‑PW‑229 engines, offering up to 129 kN thrust and achieving speeds over Mach 2.
Which aircraft uses the F404 engine?
India’s Hindustan Aeronautics Limited (HAL) has announced that it will procure additional F404-IN20 engines from General Electric (GE) Aerospace for its proprietary single-engine Tejas Mk 1A light combat aircraft. GE Aerospace delivered the fourth F404-IN20 engine to HAL for India’s LCA Mark 1A fighter jets, with 12 expected by year-end. Despite a 2021 deal for 99 engines, supply chain disruptions pushed deliveries to March 2025.GE Aviation will supply the initial batch of F414-GE-INS6 engines and the rest will be manufactured in India under transfer of technology arrangement. The F414-GE-INS6 is the highest-thrust F414 model and includes state-of-the-art technology to meet India’s demanding Air Force and Naval requirements.
