Kinetic Kill Vehicle Divert & Attitude Control Thrusters

Exoatmospheric and upper-atmosphere missile defense dispenses with explosive warheads entirely, relying on the sheer kinetic energy of hit-to-kill collisions at closing speeds exceeding 15,000 miles per hour. Missile guidance systems in the hypersonic missile defense Golden Dome space stocks playbook explore how Divert and Attitude Control Systems (DACS) provide terminal maneuvering authority.

A Kinetic Kill Vehicle (KKV) carries a central divert propulsion assembly consisting of high-response solid or liquid rocket thrusters situated around its center of gravity. These thrusters fire in millisecond pulses to translate the kill vehicle laterally without altering its pointing angle.

Simultaneously, micro-attitude control thrusters positioned along the periphery slew the onboard cryogenically cooled infrared seeker to keep the maneuvering incoming target perfectly centered on the optical focal plane until direct kinetic collision obliterates the threat.
