Hello friend. I entirely agree with your point of view. By the way, what you wrote is what I read most of the time. It is no exaggeration to say that the aircraft came first, precisely because, at least from what I read, the requirement for a CAS aircraft to have been made first. I think the cannon was added later. So much so, that they studied many existing attack aircraft, including those from World War II to be able to produce a good CAS aircraft. Yes, there was the thought of making a turboprop aircraft but then they changed precisely because of fragility. So, I believe the aircraft has been modified to accommodate the cannon and tub. The landing gears have also undergone change, including the landing gear near the nose that is not positioned exactly on the centerline. The position of the engines also I think has changed due to the move to lower the infrared signature.
