# To Break the Ice (DD-318)

> Icebreakers are ships built to clear paths through sea ice. Their sloped, reinforced bows let them ride up onto the ice so the ship's weight breaks it, and strengthened hulls protect them from damage. They keep polar shipping routes and research expeditions moving. The footage shows a red-hulled icebreaker pushing through pack ice.

## Quick facts

- **DD-318-F01**: Icebreakers clear paths through ice. _(Write-up · Exhibit A (Purpose))_
- **DD-318-F02**: Sloped bows ride up onto ice. _(Write-up · Exhibit B (Bow))_

## Write-up

Icebreakers ride up onto the ice and crush it with their weight. Their reinforced bows are built to take the strain.

1. **Purpose**: Icebreakers clear paths through ice.
2. **Bow**: Sloped bows ride up onto ice.
3. **Weight**: The ship's weight breaks the ice.
4. **Hull**: Hulls are strengthened.
5. **Polar**: They support polar routes.

## Reel vs. record

- **Note**: The Reel calls the bow features 'icebreaker bulbs' or 'ice horns'; I could not confirm those terms. Icebreakers mainly rely on a sloped, reinforced bow.

### Transcript

Did you know, icebreaker ships are equipped with specially designed icebreaker bulbs at the bow to help them navigate through icy waters? These bulbs, often referred to as icebreaking or ice horns, are reinforced extensions of the hull that allow the ship to push up onto thick ice sheets, breaking them under the vessel's weight. The bulb's rounded shape also helps reduce resistance by cutting through ice more efficiently, protecting the ship's hull from damage. This design is critical for polar expeditions and shipping routes in icy conditions, ensuring that essential supplies and research missions can continue, even in harsh, frozen environments. NOW YOU KNOW!
