Constructing the Javelin SDZConstruct the SDZ for a Javelin guided missile firing an HE warhead into steel.

Information about this weapon system and its SDZ can be found by referring to DA-PAM 385-63, Chapter 15, paragraph 3 and Figures 15-10, 15-11 and 15-12.

The trajectory limit angle = 21°

At the launch point, measure 21° from the left and right of the missile target line.

Draw tic marks.

From the launch point, draw straight lines through the tic marks out through Distance X.

This establishes the left and right Trajectory Limits and defines the Impact Area.
