BAE, Thales and lot of other companies sell off the shelf mission computers. You just can google it.
The companies that sell mission computer also offer servies to develop flight control law. Also third part servies are aviable for the same.
It doesn't matter how you do what matters is the end result. The fact remains Tejas still not mass deployed.
This hold true for all our projects be it drones (DRDO Rustom) or aircraft where we have still failed to operationalize our project with end user while our adversaries have be it Turks with their drones or Pakistan with JF-17 or PRC with whole plethora of aircraft and drones.
Even Pakistani have developed their UCAV and we are still stuck in Taxi trails for our UAV/UCAV and at the same time buying IAI Heron.
As per you mission computers and fly-by-wire control laws are small part then was it worth wasting a decade on that rather that working with Americans and have incremental development cycle there by reducing development time.
Same goes for Kaveri engine. We coupled Kaveri engine program with Tejas. These caused delays when the Kaveri engine project failed we went to GE404 and took more time.
You are not getting extra point for reinventing the wheel. You are getting the project delayed.
You can't be in a perpetual cycle of endless development and no product to show for.
We are almost at the end of 2021 yet the aircraft is not mass deployed. Remember one thing in real life only results matter and not the process. Yes we learnt a lot but what we gained from it. How will you quantify the lives of Pilots lost in Mig-21, the aircraft that was supposed to be replaced with Tejas? The aircraft that can't be phased out until equivalent number of Tejas are available.
Remember the goal of Tejas is to replace Mig-21 and be one of the mass deployed supersonic fighter aircraft in our forward airbases and not be academic project for our government agencies.
1.mission computer has nothing to do with fly by wire control laws software and hardware,
It took 5 years just to build the Iron Bird test rig that ran Tejas fly by wire , watch hamara Tejas part 5.
2. offshore assistance fr fly by wire means you hv to go to them every time , when you want some config redesign , pay what ever they charge. like $2 billion fr integrating india specific upgrade, you will pay again when you want to upgrade something ten years later, no one will know the real cost of ownership of ownership.
3. Spending tax payer money to upgrade MNCs' R&D will always make india a client state. Because the people infra and know how to develop a future fly by wire software and hardware comes from atleast one fully locally developed local effort like tejas.
3.fly by wire is refined continuously based on pilot input even after FOC,
4. fly by wire tech is the core of any relaxed static stability fighter , no small part.
5. If IAF gave orders fr pure air to air version of Tejas ,that are to be deployed in our punjab , rajasthan, Gujarath borders, it could hv ordered 100 tejas in 2011 itself, because tejas proved HMDS and rdr cued R73E firing in 2009 itself. IAF cd hv asked ADA to just prove derby and gun certification,
and we cd hv had 100 tejas flying by now , all can be upgraded to Tejas mk1A level at mid life upgrade,
If this was done IAF wd hv reired all its migs by now. It was IAF's insistence on proving tejas in all theaters and all roles beyond doubt that delayed tejas, SO blaming loss of mig21 pilots in the past decade on Tejas is unfair
lotof people dont understand that while tejas is a mig21 replacement in squadron numbers, it is mirage 2000 successor in terms of tech. only other fighter that has equivalent fly by RSS tech in IAF is rafale, the mirage 2000 successor, In the same way solid fly by wire 4 channel all digital RSS fly by wire tech fr AMCA will make it rafale successor in terms of aerodynamics, that comes from tejas base, I dont know which firm will gives us such tech
but IAF wanted it to be customized fr multi role, LEH operation , refuelling etc, etc, Till 2019 couple of all typhoons that flew needed other fighters to assist them in ground bombing, That didnt stop Europeans from building 100s of pure air to air certified Typhoon and inducting them,
Same with F35 even without an FOC USAF has added 100s in fleet,
SO "lack of mass production is due to the fact IAF set a different gold standard fr inducting Tejas" diametrically opposite to world standards and even its own standards fr SU 30mki, mig29, mirage 2000, which were all added with minimum capacity upfront.
but these are all irrelvant to AMCA project.
What AMCA has is a solid base for flawless fly by wire that has been proved over 10000 event free flight hours of tejas program,
Even the last mirage2000 upgrade that crashed oh HAL runway crashed due to fly by wire defect, that too after 50 years of this type in service.
depending upon a foreign entity fr such a crucial R&D is not a good strategy
