World War II aircraft carrier idea

During World War II, the United Kingdom considered building a massive aircraft carrier made of ice and wood pulp, as reported by Diario Uno. The project, named Habakkuk, was proposed in 1942 to help fight German submarines in the Atlantic Ocean.

Purpose of the carrier

The idea was developed by Geoffrey Pyke, a British researcher aiming to protect Allied convoys from submarine attacks. At the time, German submarines were targeting ships carrying food, fuel, and military supplies to Europe, and Allied aircraft struggled to cover parts of the central Atlantic.

Design of the carrier

The proposed structure would have been about 610 meters long and 90 meters wide, making it an extraordinary floating air base. Researchers created a material called pykrete, a mix of frozen water and wood pulp, to significantly increase the strength of regular ice. The project also included an insulation system and refrigeration devices to control melting.

Prototype built in Canada

A prototype of the project was built in 1943 near Patricia Lake in Alberta, Canada. The Alberta Aviation Museum states that this smaller model was about 18 meters long and 9 meters wide, weighing around 1,000 tons. The experiment showed that a pykrete platform could stay afloat, but mass production would have needed vast amounts of wood pulp and complex refrigeration systems.

Project abandoned

As the war continued, improvements in radar, longer-range aircraft, and better protection from escort ships reduced the need for such a large floating air base. The Habakkuk project was eventually abandoned, leaving only the prototype on a Canadian lake.
