Launch, boost, sustain describes which missile characteristic?

• A. Engine thrust profile
• B. Flight path control
• C. UV missile plume phases as detected by AN/AVR-57 CMWS
• D. Sensor sensitivity during flight

Answer: (C)

Understanding how a missile’s UV plume evolves over time is what this item is about. The phrase Launch, boost, sustain refers to the typical progression of a missile’s exhaust plume as seen by ultraviolet detectors. In systems like the AN/AVR-57 Counter-Measures Warning System, UV sensors track the plume’s signature as it goes through ignition (launch), main propulsion burn (boost), and the continuing plume state (sustain). This temporal pattern is distinctive and is used to identify and classify a threat. Why this fits best: the description is about how the plume itself changes in the UV spectrum and how that change is detected by the CMWS. It’s not describing how much thrust the motor produces over time, which would be an engine thrust profile, nor a control or guidance mechanism (flight path control), nor merely how sensitive a sensor is (sensor sensitivity). So the phrase points to UV plume phases detected by the AN/AVR-57 CMWS.
