To intercept an ICBM, an S-400 missile would need to exceed Mach 20 (24,000 km/h) to catch the hypersonic re-entry vehicle. The current 40N6E missile peaks at Mach 14, forcing Russia to build the S-500 Prometheus for true intercontinental defence.

How fast would an S-400 missile need to be to intercept an ICBM?

An ICBM is significantly faster than any S-400 missile. Strategic ICBMs reach staggering velocities of Mach 20 to Mach 25 (30,000 km/h) in space, easily outpacing the S-400's fastest interceptor, the 40N6E, which peaks at Mach 14 (17,000 km/h).

ICBM vs S-400 missile: Which one is actually faster?

The S-400's famous 400-km range only applies to aircraft. Against ballistic missiles, its protection envelope shrinks to a 60-km radius (11,300 sq km) due to the extreme speed of incoming threats, forcing it into a strict point-defence role.

How much territory could an S-400 actually protect from a ballistic missile?

From the wrestling mat and hockey field to the cricket pitch, swimming pool and running track, these films have celebrated sporting heroes who dared to dream and persevered until they turned those dreams into reality.&nbsp;
