Figure 15
A line graph titled 'High Angle RV - Gravity' displays the trajectories of two interceptors and an RV. The x-axis represents distance in kilometers ranging from 0 to 200 kilometers, and the y-axis represents altitude in kilometers ranging from 0 to 150 kilometers. The RV trajectory, represented by a yellow line, starts at the right, peaks at around 150 kilometers altitude, and descends. Two interceptor trajectories are shown: one with a 110-second time delay (blue line) and another with a 50-second time delay (green line). Both interceptors start from the left, with the green line showing a more erratic path compared to the smoother blue line. The interceptors meet the RV at different points along its trajectory. All values are approximated.Feasible ballistic trajectory intercept for two interceptor launch delay times with gravity. Interceptor speed is MACH 4 from left to right and RV speed is MACH 5 from right to left
