How to Draw a Submarine
Learning how to draw a submarine is a practical way to practice perspective, industrial design, and clean line work.
This guide breaks the process into simple steps so you can build a recognizable submarine sketch without guesswork.
Submarines are visually interesting because they combine basic geometry with detailed engineering features like a periscope, propeller, hatches, and fins.
By starting with an oval body and adding structured details, you can create a drawing that looks believable and polished.
What You Need Before You Start
You do not need advanced tools to draw a submarine.
A pencil, eraser, and plain paper are enough for a beginner-friendly sketch.
- Pencil for sketching the base shape
- Eraser for correcting proportions
- Black pen or fineliner for outlining
- Colored pencils, markers, or digital brushes for shading
If you are drawing traditionally, use light pencil pressure in the first stage.
That makes it easier to adjust the hull shape, which is the most important part of the submarine design.
Step 1: Draw the Main Body
Start with a long horizontal oval or capsule shape.
This will form the hull, which is the main body of the submarine.
Keep the front slightly rounded and the back a little narrower to suggest movement through water.
Think of the body as a streamlined shape rather than a perfect tube.
Real submarines are designed to reduce drag, so smooth curves will make your drawing feel more realistic.
Step 2: Add the Front Section
Submarines usually have a rounded nose at the front.
Refine the front end by softening the curve and making it slightly thicker than the back.
This helps the submarine look sturdy and engineered for underwater travel.
You can add a thin line near the front to indicate a seam, viewport, or structural panel.
Keep it subtle so the drawing remains clean and readable.
Step 3: Sketch the Sail or Conning Tower
The sail, also called the conning tower, is the raised structure on top of the submarine.
Draw a tall rounded rectangle or a slightly curved block near the middle-upper section of the hull.
This feature is important because it instantly identifies the object as a submarine.
Place it slightly forward of center for a balanced silhouette, then connect it smoothly to the hull so it does not look pasted on.
Step 4: Add the Periscope and Antennas
From the top of the sail, draw one or two thin vertical lines to represent the periscope or antennas.
These details add technical realism and help the submarine appear active and functional.
If you want a more modern submarine look, keep the top details minimal.
If you want a classic military submarine style, make the periscope more noticeable and add a second small mast beside it.
Step 5: Draw the Tail Section
At the rear of the submarine, narrow the body slightly and add the tail assembly.
This usually includes fins or stabilizers arranged around the back end.
Sketch two side fins and a lower fin to create the impression of control surfaces.
Then add a circular propeller or a simple propeller hub at the very back.
Even if you do not draw every blade, a visible rear propulsion area makes the design feel complete.
Step 6: Add Hatches, Windows, and Panels
Once the major shape is in place, add surface details.
These may include circular hatches, small windows, panel lines, or access ports.
Use light, simple lines so the hull does not become too busy.
- Draw a few evenly spaced panel lines along the body
- Add one or two small portholes if you want a cartoon or explorer style
- Include a hatch ring on the sail for a more technical look
Industrial vehicles look convincing when details follow the surface form.
Curve your panel lines slightly around the hull instead of keeping everything perfectly straight.
How to Draw a Submarine with Better Proportions
Good proportions make a submarine sketch look accurate.
The hull should usually be much longer than it is tall, while the sail should remain smaller than the body it sits on.
A useful guideline is to keep the sail about one-fifth to one-quarter of the hull height.
The tail should also taper gently rather than ending abruptly.
These proportion choices help the submarine look functional instead of cartoonish unless that is the style you want.
How to Add Shading and Depth
Shading transforms a basic outline into a more dimensional drawing.
Decide where your light source is coming from, then shade the opposite side of the hull more heavily.
Use soft gradients on the rounded body to show its cylindrical form.
Darken the underside slightly to suggest underwater shadow, and add a stronger shadow beneath the sail where surfaces overlap.
- Use lighter shading on the top curve of the hull
- Darken recessed lines, seams, and panel gaps
- Add a reflected highlight along one side for a polished metal effect
If you are using color, muted gray, navy, olive green, and blue tones work well for submarine drawings.
A darker background can make the vessel stand out even more.
How to Draw a Cartoon Submarine
If you want a friendlier style, simplify the shapes and exaggerate the features.
Make the body rounder, the windows larger, and the sail shorter and more playful.
You can also add a smiling face, bright colors, or decorative stripes.
Cartoon submarines are popular in children’s illustrations because they are easy to recognize and fun to customize.
How to Draw a Realistic Submarine
For a realistic approach, focus on clean construction and restrained detail.
Real submarines have smooth hulls, limited external features, and carefully placed control structures.
Study reference images of naval submarines, research vessels, or underwater exploration submersibles.
Pay attention to the difference between a military submarine, a deep-sea submersible, and a cartoon version so you can match the design style accurately.
Realistic drawings often benefit from these details:
- Minimal external clutter
- Smooth tapered hulls
- Functional fins and control surfaces
- Subtle surface paneling
- Controlled shading for metal texture
Common Mistakes to Avoid
Many beginners make the submarine too boxy or place the sail too high on the hull.
Others add too many details too early, which can make the drawing feel crowded.
Keep the main body simple first, then build outward from the largest shape to the smallest.
This method is especially useful if you are learning how to draw a submarine for the first time.
- Do not make the hull perfectly straight
- Do not place the sail off-center without intention
- Do not overdraw the propeller area
- Do not use heavy lines before checking proportions
Ways to Customize Your Submarine Drawing
Once you know the basic structure, you can adapt the submarine for different scenes.
Add underwater plants, bubbles, fish, sonar pings, or a seabed to turn the sketch into a full illustration.
You can also change the design to fit a specific theme, such as a military vessel, a scientific research submarine, or a fantasy underwater craft.
Small changes in shape, color, and surface detail can dramatically change the final result.
If you are drawing for a story, game, or classroom project, consider adding a mission insignia, viewing port, or equipment bay.
These elements help your submarine design feel unique while still staying recognizable.
