Analyst Note:
This image shows the MK 136 Third Stage Rocket Motor of a U.S. RIM-161 Standard Missile 3 (SM-3) Blk I interceptor missile. The SM-3 Blk I variants share the same propulsion sections, but have differences in the kill vehicle section. The SM-3 Blk II variants are substantially different, including new, larger-diameter propulsion sections. SM-3 missiles have a booster, dual-thrust rocket motor, third-stage rocket motor, and an altitude control section in the kill vehicle. (ARES)
The munition has either partially or fully operated and the intended effect has occurred. For explosive munitions, this usually means a detonation.
