Constructing the Javelin SDZ Construct 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 , Chapter 15, paragraph 3 and Figures 15-10, and
August 2003 Weapon: Ammo Type: Fly-out Probability Distance X: Trajectory Limit: Area A: Area B: PDA/CA1/CA2/CA3: Map Scale: SDZ/Area F Map Sheet: Map Series: Map Edition: Date: Name: Legend for the Javelin
August 2003 Plot the launch point and the firing line. Plot the target. Establish the missile target line.
August 2003 From Figure , Chapter 15-3 find Distance X for the Javelin missile. Distance X = 4000m Annotate Distance X on the legend. Distance X
August 2003 To establish the right and left trajectory limits, refer to Chapter 15-3 and find the angle for a missile with the fly out probabilities of 1 in 1,000,000. Distance X The trajectory limit angle = 21° At the launch point, measure 21° from the left and right of the missile target line. 21°
August 2003 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. Impact Area 21° Left and Right Trajectory Limits Distance X
August 2003 Area A is 500m wide for HE warhead rounds from the launch point to a point 1000m downrange. Impact Area Left and Right Trajectory Limits 1000m The remaining downrange portion of Area A tapers down to a 200m width for HE warhead rounds at Distance X. From the firing line, measure 1000m downrange. Distance X
August 2003 Lightly draw lines perpendicular to the trajectory limits between the firing line and 1000m downrange. Impact Area Draw tic marks at 500m as shown. Draw straight lines through the tic marks from the firing line out past the 1000m measurement. Left and Right Trajectory Limits 1000m Distance X
August 2003 At Distance X, measure 200m out from the trajectory limits and draw tic marks. Impact Area Draw straight lines from where the last line drawn intersects the 1000m line out through the tic marks as shown. 1000m Distance X
August 2003 Place needle of the compass at the launch point and scribe an arc between the trajectory limits. Use Distance X as the radius. Impact Area This completes Area A. Erase unnecessary lines. Area A Annotate Area A on the legend. Left and Right Trajectory Limits 1000m Distance X
August 2003 Impact Area Lightly draw a line extending the missile target line. Area A Place a tic mark at the measurement for Area B. In Chapter 15-3, the measurement stated for Area B = 500m Place needle of the compass at the launch point and scribe an arc through the tic marks between the trajectory limits. Left and Right Trajectory Limits 1000m Distance X
August 2003 Impact Area Area A This completes Area B. Erase unnecessary lines. Annotate Area B on the legend. Area B Left and Right Trajectory Limits 1000m Distance X
August 2003 Impact Area Area A This completes Area B. Erase unnecessary lines. Annotate Area B on the legend. Area B Left and Right Trajectory Limits This SDZ requires an Area F to the rear of the launch point. 1000m Distance X
August 2003 Locate the launch point and the baseline. 100m From the launch point, lightly extend the missile target line 100m, the measurement of Caution Area 3. From the launch point, place a tic mark at 25m from the baseline, the measurement of the Primary Danger Zone. 25m Note: Scale for Area F is 1:750
August 2003 Scribe an arc from the 25m tic mark to the left and right sides of the baseline. From the launch point, measure 30° from to the right and left of the extension of the missile target line. 25m Draw tic marks. 30° 100m
August ° Draw straight lines through the tic marks. 100m 25m 35m Measure 35m down from the launch point for Caution Area 2 and draw a tic mark. With the needle of the compass in the launch point scribe an arc through the tic mark as shown.
August ° 100m 25m 35m Place the needle of the compass in the launch point and using the length of Area F (100m) as the radius, scribe an arc as shown.
August 2003 Annotate the Primary Danger Zone. Annotate Caution Area 1. Annotate Caution Area m 25m 35m Annotate Caution Area 3. Primary Danger Zone Caution Area 1 Caution Area 2 Caution Area 3
