China's First Heavy Icebreaker: Advancing Polar Exploration and Scientific Capabilities

Wu Gang, Chief Expert at the No. 708 Research Institute of China State Shipbuilding Corporation (CSSC), recently shared updates on China’s ongoing project to design and build its first heavy icebreaker.

Once operational, this heavy icebreaker will be able to break through ice over 2 meters thick and endure the harshest polar conditions. It will also be highly intelligent, environmentally friendly, and powered by green fuel to ensure no pollutants are left behind during its operations.

25 Years of Progress: From Light to Medium Icebreakers
China has made significant strides in its polar exploration capabilities over the past 25 years. The International Maritime Organization (IMO) categorizes icebreakers from PC1 to PC7, with PC1 and PC2 being heavy icebreakers capable of breaking ice over 2 meters thick. So far, China has three operational polar research vessels:
- Xuelong (PC6): Light icebreaker
- Xuelong 2 (PC3): Medium icebreaker
- Jidi: Light icebreaker

The Road to Heavy Icebreakers: A Long-Term Mission
Wu Gang expressed confidence that China’s advancement from PC3 to PC2 and PC1—the top tier of icebreaking capabilities—will take less time, though it remains a long-term endeavor. Achieving such powerful icebreaking performance requires overcoming a series of technical challenges, including: High-strength, corrosion-resistant outer shells，reliable systems to crush through thick ice, Materials and technologies to withstand extreme temperatures, environmentally friendly coatings and propulsion systems and advanced navigation systems for precise polar operations

With this new heavy icebreaker, China is set to further strengthen its polar research, shipping, and governance capabilities, laying the foundation for future advancements in the“light-to-medium-to-heavy” icebreaking system.
