It is the biggest obstacle.AMCA can come sooner, technology is not problem here but funding and govt attitude is. If you feed peanuts to the developmental agencies then you get peanuts in return.
India has completely avoided R&D on stealth-associated technologies for years.
The only right thing the Govt has done was to ask for a private partnership, given astronomically funding that is required for stealth R&D
Anechoic Chamber is the only technology we possess and maybe over time software designed for reduced observables can be built
Israel possesses every one of the below technologies. If Adani can fund and obtain the ToT from them, we may get lucky.
Then comes the challenges of integrating them and getting a functional fighter jet.
- Devices for reduced observables such as radar reflectivity, ultraviolet/infrared signatures and acoustic signatures (i.e. stealth technology)
- Radar absorbing material foams
- low-dielectric foam (epoxy)
- lightweight lossy foam (urethane)
- sprayable lightweight foam (urethane)
- thermoplastic foam (polytherimide)
- Resistive Cards
- Loaded ceramic spray tiles
- Absorbing honeycomb
- Radar absorbing material foams
- Systems, specially designed for radar cross section measurement
- Anechoic Chamber
- Target Support Devices
- Bidirectional Arches
- Materials for reduced observables such as radar reflectivity, ultraviolet/infrared signatures and acoustic signatures (i.e. stealth technology)
- Magnetic Radar Absorbing Material
- Transparent Radar Absorbent Material (T-RAM)
- Infrared (IR) Treatments
- "Software" specially designed for reduced observables such as radar reflectivity,ultraviolet/infrared signatures and acoustic signatures
