Please dont take this as trolling
A little of perspective is needed with this JF17 semi stealth business or sino pak fifth gen project business.
JF17 is a low cost budget fighter. The totally development cost was very small in deed. The fly away cost of $15m reflects the time. energy and the technology in the project.
BY THE WAY I THINK ITS A FINE PLANE FOR SOUTH ASIAN NEEDS AT very little cost.
COMPARE the marginally bigger J10/FC20 project which has been in development longer 3 times the budget and costs $30m each. YET it is not in the same catagory as Typhoon or Rafale projects in terms of cockpit tech ,electronics radar and jammers.
To develope a REAL FIFTH gen fighter you need to compare time and cost with a similar project
PAK FA will cost upwards of $15 billion and will not enter service with Russia before 2018 and india 2020 and both these countries have huge advantages that are not open to either pakistan or china.
In india case access to open western Europe or israeli technology esp in cockpit sensor fusion and radar work
Russia vast aero space edge over china and succesful building projects and base in place already.
WITH THIS MIND BE CAREFUL OF EXPECTING A SUPER JF17 semi stleath fighter ever arriving and even if it did dont expect this before 2020
