b) It travels at a hypersonic speed.
c) These missiles are guided by an inertial navigation system that is updated during flight using contour maps stored in the system’s computerized memory.
d) It uses a three-stage solid rocket booster to propel itself out of Earth’s atmosphere at near-hypersonic speed.
e) After reaching into space, it activates its sophisticated sensors to identify and track the incoming target.
