  - Future mobile launcher configurations

Operational Concept:
  1. SPY-1 radar detects and tracks threat
  2. Aegis weapon system calculates intercept geometry
  3. SM-3 launches vertically from Mk 41 VLS
  4. First stage boosts missile above atmosphere
  5. Second stage accelerates to hypersonic speed
  6. Third stage provides final velocity boost
  7. Kill vehicle separates and homes on target
  8. Direct collision destroys warhead in space
