The missile crossed Japan at a sub-orbital altitude, and the Japanese authorities knew that it would as soon as the boost phase ended.
Though still on the drawing board, space weapons will someday be able to target intercontinental ballistic missiles during their initial boost phase, when the large plume of their engines makes them easiest to detect and their slow upward ascent makes them most vulnerable.
During the boost phase, the missile remains in one piece and gives off a large plume, making it easier to identify and target, experts noted.
The YAL-1 Airborne Laser Testbed, as the aircraft came to be known, was used by the US Department of Defence's (DOD) Missile Defence Agency, and carried a chemical oxygen iodine laser that could track and destroy a ballistic missile during its boost phase, after the missile has been launched, but before the missile reached its peak velocity.
Ballistic missiles follow a three phase trajectory; boost phase, midcourse or exo-atmospheric phase, and terminal or endo-atmospheric phase.

To attack mobile targets, a medium-range ballistic missile (MRBM) (or one with longer range) must maneuver after boost phase to remove the differences in a target's position due to unpredictable motion between time of launch and target impact.
These included now-defunct Pentagon programs to hit a missile shortly after launch, in its so-called boost phase.
