I don't know but $4.6 billion for 40 JF-17 Block 3s sounds too much, $4.6 bil for 64 sounds more plausible
It also doesn't mention that order was simply increased from 16 to 40, it says just a new contract for 40 aircraft, the previous deal for $1.6 bil was signed last year.
Yeah, that was the thought process, it probably has very massive AESA radars to identify AWACS and Refueling aircraft at ranges of 400 to 500 kms, pretty much a mini-AWACS itself.
I believe the 40 is the additional number on top of the current 24 on order, so total of 64 for $4.2 billion sounds more plausible than $4.2 billion for just 40, that would be more than $100 million per airframe. Although nothing is confirmed outside of the initial 24 currently on order.
Not sure how reliable this source is, but its reporting an additional possible sale of 40 JF-17s for $4.2 billion
