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

Legend for the Javelin 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: August 2003

Establish the missile target line.
Plot the target. Establish the missile target line. Plot the launch point and the firing line. August 2003

Annotate Distance X on the legend.
From Figure 15-10, Chapter 15-3 find Distance X for the Javelin missile. Distance X = 4000m Annotate Distance X on the legend. Distance X August 2003

The trajectory limit angle = 21°
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. Distance X Impact Area 21° Left and Right Trajectory Limits August 2003

From the firing line, measure 1000m downrange.
Area A is 500m wide for HE warhead rounds from the launch point to a point 1000m downrange. 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 Impact Area Left and Right Trajectory Limits 1000m August 2003

Draw tic marks at 500m as shown.
Lightly draw lines perpendicular to the trajectory limits between the firing line and 1000m downrange. Draw tic marks at 500m as shown. Distance X Draw straight lines through the tic marks from the firing line out past the 1000m measurement. Impact Area 1000m Left and Right Trajectory Limits August 2003

At Distance X, measure 200m out from the trajectory limits and draw tic marks.
Draw straight lines from where the last line drawn intersects the 1000m line out through the tic marks as shown. Distance X Impact Area 1000m August 2003

Annotate Area A on the legend.
Place needle of the compass at the launch point and scribe an arc between the trajectory limits. Use Distance X as the radius. Distance X This completes Area A. Area A Impact Area Annotate Area A on the legend. 1000m Left and Right Trajectory Limits Erase unnecessary lines. August 2003

In Chapter 15-3, the measurement stated for Area B =
Lightly draw a line extending the missile target line. Place a tic mark at the measurement for Area B. Distance X Area A Impact Area Place needle of the compass at the launch point and scribe an arc through the tic marks between the trajectory limits. 1000m Left and Right Trajectory Limits August 2003

Annotate Area B on the legend.
This completes Area B. Annotate Area B on the legend. Erase unnecessary lines. Distance X Area A Impact Area 1000m Left and Right Trajectory Limits August 2003

Annotate Area B on the legend.
This completes Area B. Annotate Area B on the legend. Erase unnecessary lines. Distance X Area A This SDZ requires an Area F to the rear of the launch point. Impact Area 1000m Left and Right Trajectory Limits August 2003

Locate the launch point and the baseline.
100m 25m Note: Scale for Area F is 1:750 Locate the launch point and the baseline. 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. August 2003

100m 25m 30° 30° 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. Draw tic marks. August 2003

Draw straight lines through the tic marks.
30° 30° Draw straight lines through the tic marks. 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 2003

100m 35m 25m 30° 30° 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.
Caution Area 1 100m Caution Area 2 Caution Area 3 Annotate the Primary Danger Zone. Annotate Caution Area 1. Annotate Caution Area 2. Annotate Caution Area 3. August 2003
