What are the two motors within the FGM 148?

• A. Launch motor and propulsion motor
• B. Launch motor and flight motor
• C. Flight motor and propulsion motor
• D. Propulsion motor and guidance motor

Answer: (B)

The FGM-148 uses a two-stage propulsion system: a launch (boost) motor and a flight (sustain) motor. The launch motor provides the initial thrust to push the missile out of the launcher and accelerate to a stable speed. After it burns out, the flight motor takes over to provide sustained thrust during the rest of the flight, carrying the missile toward the target. This pairing—launch motor and flight motor—is the standard way to describe the propulsion stages inside the missile. The other options mix in a generic propulsion motor or reference a non-existent “guidance motor,” which doesn’t describe the actual propulsion stages.
