The Mirages 2000 also have the GMTI since the 80's, if the Rafale didn't have it it was because it wasn't important, the Americans do everything it is possible to do and the French do what is most useful to their mission and over time add less useful functions according to their order of priority. The result is that at the beginning the American system is very complex and doesn't work unlike the French system. Anyway, now the Indian Rafales already have the GMTI and it will be introduced on the French Rafales with F4.1. And there is no function of the F-18 SH that makes the Rafale owners envious.
