There is something irresistibly charming about a little yellow submarine cruising through the deep blue sea. With its round porthole windows, tiny periscope, and spinning propeller, a cartoon submarine is the perfect subject for anyone who loves drawing vehicles with personality. The shapes involved are simple and forgiving, which makes this a great pick for beginners who want a fun, satisfying result.

How to Draw a Submarine for Beginners
What You Will Need
  • Pencil
  • Eraser
  • White paper
  • Black marker or fine-liner (optional)
  • Colored pencils, crayons, or markers
1

Draw the Body Outline

Step 1: Draw the Body Outline

Start in the center of your paper and draw a long, narrow oval shape — wider and rounder on the left side, tapering to a gentle point on the right. This elongated oval forms the main body of the submarine, so make sure it stretches comfortably across your page.

2

Add the Front Porthole

Step 2: Add the Front Porthole

On the rounded left end of the body, draw a small oval standing on its side. This will become the front window of the submarine, sitting right at the very front of the hull where the captain might peek out to see what is ahead.

3

Define the Front Window Edge

Step 3: Define the Front Window Edge

Just behind the small oval you drew in Step 2, add a curved line running from the top of the body down to the bottom, following the natural curve of the hull. This line separates the rounded nose section from the rest of the submarine's long body.

4

Draw the Periscope Base

Step 4: Draw the Periscope Base

On top of the body, slightly left of center, draw a small rounded rectangle shape sitting upright like a little tower. This base will support the periscope and acts as the entry hatch you often see on top of classic cartoon submarines.

5

Add the Periscope and Antenna

Step 5: Add the Periscope and Antenna

From the top of the periscope base, draw a thin bent pipe shape that goes up and then curves to one side, ending in a small oval — this is the periscope lens. Just beside it, add a thin straight line with a tiny circle on top to create a small radio antenna.

6

Draw the Side Portholes

Step 6: Draw the Side Portholes

Along the main body of the submarine, draw three evenly spaced circles in a row, each with a smaller circle inside it. These represent the round side windows, or portholes, that let light into the submarine's interior. Also add one more small circle on the front of the periscope base for a tiny window detail there too.

7

Add the Stripe and Tail Fin

Step 7: Add the Stripe and Tail Fin

Draw a long horizontal line running along the lower section of the body from the front all the way to the back — this creates the colored stripe band typically seen on cartoon submarines. At the back end of the body, draw a small triangular fin pointing upward, giving the submarine its tail structure.

8

Draw the Propeller

Step 8: Draw the Propeller

At the very back tip of the submarine, draw a small propeller made of two or three curved blade shapes meeting at a center point, like a little pinwheel. This propeller is what powers the submarine through the water, so it should sit right at the rear point of the body.

Color Your Submarine

Step 9: Color Your Submarine

Now for the most exciting part — bringing your submarine to life with color:

  • Main body: Bright golden yellow
  • Stripe band, periscope, antenna base, and fin: Deep blue
  • Portholes and front window: Light sky blue with a small white highlight for a glassy effect
  • Periscope lens and porthole rings: Deep blue outline around the light blue glass
  • Propeller: Deep blue

Your cheerful little submarine is ready to set sail beneath the waves!

Final Thoughts

Drawing a submarine is a great way to practice combining simple ovals and rectangles into something that feels like a real, functioning machine. Each small detail — the periscope, the portholes, the propeller — adds personality without requiring any complicated shapes. Once you've drawn one cute submarine, you'll find it gets faster and more confident every time you try it again.

Feel free to experiment with different colors for your submarine's body and stripe. A red and white version, or even a deep-sea green one, can look just as fun as the classic yellow!
