I do not understand The J 10 was replaced by pictures of Indian planes by user 59 94 128 224 who is from India This leads me to think as to why he or she did so Both the Su 27 and 30 are Russian The F 2 and F CK 1 are Japan United States and Republic of China United States co produced planes They are representative of American jets not planes from Japan or Republic of China Taiwan Both the J 10 and Tejas are equipped with foreign engines thus not fully indigenous Even some parts of the Typhoon is subcontracted to the United States If you wish to remove planes then remove all except for American Russian planes
