Abstract: An intercept missile testing method which includes the steps of launching a test missile threat from a first location on a substantially vertical trajectory, e.g., with a flight path angle greater than about 70.degree., towards an intercept point, and launching a test intercept missile from a second location on a substantially vertical trajectory, e.g., with a flight path angle greater than about 70.degree., towards the intercept point. The flight paths are selected so that the test intercept missile will intercept the test missile threat exoatmospherically, at an intercept (engagement crossing) angle of less than about 30.degree.. Preferably, the launch velocities and trajectories of the test intercept missile and the test missile threat are selected so that the intercept will occur exoatmospherically when the test missile threat is on a downward trajectory at a velocity of 5-8 km/sec, while the test intercept missile is on an upward trajectory at a velocity 5-9 km/sec.
