How Arrow 3 Steers Where There Is No Air | Grand Structures

When a ballistic missile is launched, its warhead spends the midcourse phase coasting through the vacuum of space at many times the speed of sound. To intercept it before it re-enters the atmosphere, Israel Aerospace Industries and Boeing developed Arrow 3—the outermost wall of Israel's defense array. In this documentary, we break down the extreme aerospace engineering and physics of the Arrow 3 interceptor. Discover how the Super Green Pine phased-array radar calculates a future meeting point in the sky, how the two-stage solid-fuel rocket reaches an altitude of over 100 kilometers, how a tiny kill vehicle steers itself in a vacuum using a thrust-vectoring nozzle, and why the system relies on the raw kinetic energy of a "hit-to-kill" collision instead of explosives.
