How to Draw Torpedo — Free Practice Sheets

A torpedo drawing depends on a few clear shapes: a long horizontal body, a pointed nose, and a tail assembly with fins. This guide shows how to build those parts in order, then refine the outline. The practice sheets let you trace a reference outline first, then try the contour independently. Because drawings can vary, judge your work by visible features and proportions rather than an exact match.

Start with the body and nose

Begin with the largest shape. Draw a long horizontal oval or cylinder that tapers to a point at the left end. Keep the body level and elongated; a short, round shape will not read as a torpedo. The taper should be gradual, so the nose looks pointed rather than blunt.

Next, add a curved line near the left tip. This separates the dark nose cone from the rest of the body. The curve should follow the taper of the body, not cut straight across it. If you are tracing, follow the reference outline closely; if you are working independently, compare your contour with the separate full reference sheet after you finish.

1. Draw a long horizontal oval or cylinder for the main body.
2. Taper the left end to a point for the nose.
3. Add a curved line near the left tip to mark the nose cone.

Build the tail assembly

The tail is the second identifying feature. On the right end, draw a vertical fin above the body and a matching fin below it. Add a small horizontal fin or propeller hub at the rear. Keep the fins attached to the body and aligned with its axis.

Check that the upper and lower fins are both visible. A torpedo with only one fin looks incomplete. The tail should sit at the rear, not in the middle of the body. If you are using a grid sheet, place the tail where the reference places it, using matching grid intersections.

1. Draw a vertical fin above the right end of the body.
2. Draw a matching fin below the body.
3. Add a small horizontal fin or propeller hub at the rear.

Refine the outline and add guide lines

Once the main parts are placed, outline the body with clean contour lines. Remove stray construction marks if your sheet allows. Add a few horizontal guide lines along the side to define the cylindrical shape. These lines should run parallel to the body, not across it.

Use the bounding frame and center guide to check placement before adding details. The silhouette should sit within the frame, with the nose and tail in proportion. If you are completing a blank right-hand portion, use the full reference to match the tail position and fin size. Compare your finished drawing with the reference sheet and note which features are clear and which need adjustment.

1. Outline the body with clean contour lines.
2. Add horizontal guide lines along the side for shape definition.
3. Compare your drawing with the full reference sheet and adjust proportions.

Check your work

• The body is long, horizontal, and cylindrical.
• The left end tapers to a pointed nose.
• A curved line separates the dark nose cone from the body.
• The tail has a visible upper fin and a visible lower fin.
• A small horizontal fin or propeller hub appears at the rear.
• Horizontal guide lines run along the side to define the shape.
• The overall proportions match the reference closely enough to read as a torpedo.

Worked example

torpedo: Trace the reference outline, then practise the contour independently. Compare with the separate full reference sheet.

Common mistakes

• Drawing a short, round body instead of an elongated one. Lengthen the horizontal oval and keep the taper gradual so the nose stays pointed.
• Leaving out the lower tail fin. Draw both a vertical fin above the body and a matching fin below it.
• Placing the nose cone line straight across the tip. Curve the line so it follows the taper of the body.
