The British Wanted to Build an Aircraft Carrier Out of Ice and Sawdust
Project Habakkuk envisioned a massive aircraft carrier made of "pykrete" — a mix of ice and sawdust, nearly unsinkable thanks to its slow melting rate.
During World War II, facing steel shortages, British engineers considered building a massive aircraft carrier out of a material called pykrete — a mixture of ice and wood pulp, far tougher and slower to melt than plain ice.
The project, named Habakkuk, envisioned a ship several hundred meters long with its own cooling system to keep the hull at a constant temperature, potentially serving as a floating airfield in the middle of the Atlantic.
A smaller-scale prototype was built on a Canadian lake, and it genuinely demonstrated the material’s surprising resistance to impact and its slow melting rate.
The program was eventually abandoned when the cost and logistics of building a full-size vessel proved too great, and the development of long-range tankers and air bases reduced the need for such a solution.
