What type of rocket motor does the AIM-120 utilize?

The AIM-120 missile utilizes a dual thrust rocket motor. This means that it has two different stages of thrust: a boost stage for initial acceleration and a sustain stage that provides ongoing thrust throughout most of its flight. The dual thrust design allows the missile to achieve high speeds quickly while maintaining sustained propulsion over longer ranges, which enhances its overall performance and effectiveness in engaging targets.

In addition, this design is particularly beneficial for modern air-to-air missiles like the AIM-120, as it supports the missile's ability to maneuver and adjust its course effectively during flight while maximizing speed. The boost phase propels the missile quickly to a significant altitude and speed, while the sustain phase maintains its velocity and allows for continued adjustments towards the target.
