The radar figures are taken from here. but we dont know what year that figures are published.Su-30SME specs.
110KM detection range agains 3m^2 RCS object in “free space” means lookup detection range?
Also, is the max speed of 1.75 Mach at altitude the speed while carrying missiles on hard point? This seems lackluster compared with legacy flankers.
regardless of specifications Su-30SM aka MKI is hugely successful export. total export figures may approach 450.
