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.
