Boost Phase
The boost phase is the initial part of a missile's flight path where its main rocket engines fire, propelling it from the launch site with significant thrust. During this phase, the missile rapidly gains speed and altitude.
TECHNICAL DEFINITION
The boost phase constitutes the initial, propulsive flight segment of a ballistic missile or space launch vehicle, characterized by the active firing of its primary rocket motors to achieve high acceleration and overcome gravity. This critical stage, occurring immediately after launch, is often considered the most vulnerable for missile defense systems due to the missile's intense infrared signature, relatively slow velocity, and predictable trajectory.
BACKGROUND
Missile defense is a system, weapon, or technology involved in the detection, tracking, interception, and also the destruction of attacking missiles. Conceived as a defense against nuclear-armed intercontinental ballistic missiles (ICBMs), its application has broadened to include shorter-ranged non-nuclear tactical and theater missiles.

USAGE NOTE
Missile defense systems often prioritize intercepting threats during the boost phase due to the target's large infrared signature and lower speed, maximizing the probability of a successful engagement before warhead deployment or maneuverability increases.
