IMO F-3 is too small to replace F-15. It's only JF-17 sized plus only has two 11,000 lb engines.
The size of fighter does not equate to air combat capability.
In WWII, the Mitsubishi A6M Zero was considered small compared to the British, American, Dutch variants, but it dominated the skies in the Asia Pacific for the first 3 years of the war. Speed and maneuverability gave the Japanese Zero the fighting edge, as proven when the Imperial Air Force eradicated all Dutch air units in the Battle of Java, as well as crushing American Air Power during the Conquest of the Philippines in 1942. It was much later in the war when the Americans introduced the Chance Vought F4U Corsair, that it changed the tide of naval aviation warfare.

LOL, hold your horses cowboy. It will be a gradual shift, not an acute one.
