When you compare it to JF-17, it is costly - about twice as much per plane.
No comparison in capability though.
True.
But with all due respect, Gripen and JF-17 are not in the same league as far as maturity. Like you said- not only in capability, but also in so many other areas such as design, reliability, MTBF and maintenance options. JF-17 is a great fighter but it needs to mature in operations and is yet unproven in daily use.
SAAB started with Lansens back in the fifties (four generation of fighters ago, Lansen->Draken->Viggen->Gripen), and all of them were about twenty years ahead of their respective contemporary fighter offerings at the times of their induction.
As far as capability to operate from two-lane roads in wartime (Runways bombed out), tough engine reliability in minus sixty degree weather (I know, probably not as important for us but good to know), design of maintenance points and regime, modular weapons change-out and many other factors appreciated by hardened operations people to keep these birds operational, SAAB fighters know no parallel. That is what counts and matters in day-to-day operations, not slim marginal claims of superior performance or flashy claims of obscure features not important in actual use.
Scandinavian planning and thinking are on another level compared to thinking from other countries. And don't forget how they always supported us, with our NGOs, our civil society values, our industry and our economy. We owe the Scandinavians (especially Swedes) something in return to support their economy.
If someone asks me - I will always pay a few dollars extra and go with Gripen. The question is (as mentioned already) whether they will sell the fighters to us with as little strings attached (and with support fulfillment as promised). Other than Brazil, the Thais have these and are reportedly happy with them as you can see in the video below.
First,second or even third hand.
It still costs more than cars in India.
Due to the high price of cars and heavy traffic people are reluctant in buying cars.
Well these are just simple logic which you lack.
What is telling is that Bangladeshis would rather buy a refurbished five year old Premio rather than the best brand new Indian sedan which has been available in Bangladesh for four decades. At twice the cost for a used Premio. Now what does that tell about the quality of Indian cars. In Bangladesh yearly sale of Indian sedans are under a hundred (a few dozen is my best guess).
No Bangladeshi would be caught DEAD being seen in any Indian-made car. No offense but it is what it is.
j-10 can fight very well against jf-17, mig-29, su-30, mirage
With all due respect - we do not know it yet. Especially against Su-30....
We have money. we will buy everything we want. we will buy at least 2 or 3 sq for AF and 2 sq for naval strike. just a few billion dollar does not matter for BD. BD have strong economy and 3.5 x GDP than Myanmar. blah blah blah. lol yes. BD STRONK.
