A slab of pykrete Pykrete is made of 14% sawdust and 86% water by mass.. Pykrete (/ ˈ p aɪ k r iː t /, PIE-creet) [1] is a frozen ice composite, [2] originally made of approximately 14% sawdust or some other form of wood pulp (such as paper) and 86% ice by weight (6 to 1 by weight).
Conceptual design of Project Habakkuk aircraft carrier with 600-metre (1,969 ft) runway. Project Habakkuk or Habbakuk (spelling varies) was a plan by the British during the Second World War to construct an aircraft carrier out of pykrete, a mixture of wood pulp and ice, for use against German U-boats in the mid-Atlantic, which were beyond the flight range of land-based planes at that time.
During the Second World War, the United Kingdom gave some serious thought to building virtually unsinkable aircraft carriers from ice reinforced with sawdust (Project Habakkuk). A model was made, and serious consideration was given to the project, with a design displacing 2.2 million tons and accommodating 150 twin-engined bombers on the ...
This is a list of icebreakers and other special icebreaking vessels (except cargo ships and tankers) capable of operating independently in ice-covered waters. Ships known to be in service are presented in bold. [1] [2
Pykrete is bulletproof. Confirmed The MythBusters demonstrated that pykrete is bulletproof by subjecting a wastebasket-sized chunk of ice and another of pykrete to a close range impact (approximately 10 ft or 3.0 m) by a .45 caliber round. The ice shattered upon impact, and the bullet easily penetrated it.

Twelve-year-old Elizabeth Itta submitted the winning essay, describing how the Walrus, "Aiviq" in the Inupiak language, use their tusks to break ice. She won a cash prize for her school and an invitation to attend the ship's launching ceremony on 24 March 2012. [15] [16] The vessel went for sea trials in April and was delivered on 20 April 2012 ...
Yamal can break ice while making way either forwards or backwards. Yamal is one of the Russian Arktika family of icebreakers, the most powerful icebreakers in the world. These ships must cruise in cold water to cool their reactors [failed verification], so they cannot pass through the tropics to undertake voyages in the Southern hemisphere. [3]
