This statement is self contradictory. If the work can commence due to government waiver, then why wait for Congress approval? If the work cannot commence, then what was the point of the waiver? Work on the engine aspect could have commenced after the US congress approval anyways. What is the...

The article says and I quote "work cannot begin as the US government is yet to clear it" This basically means that once the US government clears it, the work can begin. Hence the problem should ideally go away. If the problem doesn't go away with US government clearance, the article is...

So you mean to say that there are other critical components that we need from US without which work cannot begin? Firstly, I don't think so, engine is the only tech where are badly dependent. On all other components, we have either indigenous solutions in pipeline or alternative vendors...

Yes, so on those things we should start the work right? Why are we waiting for US congress approval to start work on those?

Engine was the only thing where we needed US congress approval right?

The article is self contradictory, if the centre has removed the conditionality clause, why can't the work begin on LCA MK2 till US Congress clears the engine deal?

Probably for the F414 variant, considering the fact that they have assumed that thrust of GE414 will also reduce to 90 KN in Indian conditions, which explains how they came up with the number of 180 KN for total uninstalled thrust for AMCA. But if this yardstick is being applied, it should be...

The difference between MTOW is just of one tonne. So if we assume that the AMCA is indeed limited to 6.5 tonnes of fuel and 5 tonnes of external load+1.5 tonne of internal load, it would put the empty weight of AMCA at 17 tonne, which is around 4 tonne more than that of F35. There is no reason...

F35As total load carrying capacity is around 10 tonnes excluding the humongous amount of fuel it carries. And F35 achieves it with less thrust than AMCA.

Lots of things. 1. AMCAs thrust is given to be 180 KN, while it is well known that we want to develop 110 KN engine for it, which will put total thrust at 220 KN. Even with F414, its thrust will be 196 KN. 2. External load is just limited to 5000 kg. This is a joke considering that even Rafale...

Source? Some very basic math is incorrect in this slide

On the contrary, IAF has already said that they are ok with first two squadrons of AMCA to come with GE F414 so that DRDO can get additional time for engine development.

I did, you haven't written what would you like IAF to do instead.

So what should IAF do in your esteemed opinion?

There is nothing to be gained for India by asking for YF23 tech. India is already developing stealth tech for Ghatak UCAV. Same will be used for AMCA. The current AMCA design anyways borrows heavily from YF23. Seeing US treatment of turkey, India should continue its current strategy of buying...

Source for a universal truth? It is well known that hal has quoted about 50000 crore for 83mk1a which puts their cost to around 85 million per unit.

Really? A source for this delusional claim?

You want to build a 5th gen engine without deciding on which aircraft the engine will go?

Why is our testing period so long? PAK FA will enter service only in 6 years after the first flight. We would have gained experience on Tejas already.

But atleast the timeline isn't unrealistic anymore. Also, it mentions that the aircraft will be 20t. Does anyone know if they are talking about empty weight or MTOW?
