The projectile is the munition or "bullet" fired downrange. The normal mission profile expended the stage in a high-speed splashdown some downrange. The spacecraft landed 3,500 kilometres downrange of the launch site. The vehicle flew nominally and landed within cross range and downrange of its intended target. Impact occurred only 700 miles downrange. When the pressure is released the projectile(s) are shot from the launcher sent downrange. The development of larger rockets necessitated a launch site with a big downrange. It would then be shut down, and the reactor cooled before impacting the Atlantic downrange. On December 18, AM-4 lost thrust T+117 seconds and fell into the ocean downrange. The downrange and crossrange dispersion of the targets remains classified. This time the Navy recovered it only from its planned splash down point downrange. Both vehicles plunged into the Atlantic Ocean downrange. NASA continued to list Ascension Island as a "downrange site" used for range safety instrumentation.
