We have threads for tanks and aviation so I thought I would make one for ships and other watercraft. To kick things off , here is project Habakkuk. It was developed in ww2 by Britain because they needed a new aircraft carrier to protect merchant vessels in the atlantic.
At the time resources were scarce so the royal navy had an idea to make a ship made of a material called pykrete. This material was a mixture of wood and ice which proved to not melt and worked as reasonably good armour. The carrier was planned to be 610 meters long , the largest aircraft carrier ever planned. The project came to a downfall when the amount of steel needed for supports , engines and other mechanisms was greater than what was needed to build a normal aircraft carrier.
