Its capability to be launched from submerged submarines makes it a potent component of the US nuclear triad.
How long does it take for a ballistic missile to impact?
The time it takes for a ballistic missile to impact its target depends on several factors, including the type of missile, its range, and its trajectory. Here’s a general overview of the timeframes involved:
1. Launch to Apogee
The initial phase of a ballistic missile’s flight is the boost phase, during which it accelerates rapidly. This phase typically lasts for a few minutes, but the exact duration depends on the missile’s propulsion system and intended trajectory.
2. Midcourse Phase
After reaching its highest point, the missile enters the midcourse phase, during which it follows a ballistic trajectory through space. This phase can last anywhere from several minutes to over half an hour, depending on the missile’s range and trajectory.
3. Terminal Phase
The terminal phase occurs as the missile re-enters the Earth’s atmosphere and approaches its target. This phase is relatively short, typically lasting only a few minutes.
The total time it takes for a ballistic missile to impact its target varies widely based on the above factors. Short-range missiles may reach their targets within minutes, while intercontinental ballistic missiles (ICBMs) with longer ranges may take closer to half an hour or more to complete their trajectory. The exact timing can also be influenced by factors such as the missile’s speed, altitude, and launch location. It’s important to note that missile defense systems aim to intercept and destroy ballistic missiles during their flight, ideally in the boost or midcourse phases, to prevent them from reaching their intended targets.
