actually , It is designed to be cheap ( as possible ) and secure our sky , not to attack ground and sea targets ....
so it not need to be big and heavy ... our missile will do the offensive job ...
and it is our first fighter so don't compare it with F35 with 250 billion budget ....
and we can't make something with 150 million dollar price ( I mean if we produce expensive fighter , our air force and army can't buy and operate it ... ) .....

I'm happy , compare to spend more than 50 years with F5 , it is very good .... and now we have a design and we can improve it ....
