But the S-400 is the real game changer. The reason is the multiple intercept missiles the S-400 system can fire. The S-400 supports four different missiles – the very long range 40N6E-series (400 km), the long-range 48N6 (250 km), the 9M96e2 (120 km) and the short-range 9m96e (40 km). By comparison, the US Patriot system supports only one interceptor missile with a range of 96 km.But there is more. The 9M96E2 is one of the jewels of the S-400 system. It flies at Mach 15 (around 5,000 meters per second or 18,500 kph), it can engage targets as low as 5 meters off the ground, and it can maneuver pulling up to 20 Gs (a human can withstand no more than 9 Gs with special pressure suits and helmets and for only a few seconds). It is designed to knock out penetrating aircraft and missiles flying “off the deck” or just above the ground and neutralize cruise missiles.
