"Project Habakkuk Project Habakkuk or Habbakuk (a common misspelling) 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. The idea came from Geoffrey Pyke, who worked for Combined Operations Headquarters. After promising scale tests and the creation of a prototype on a lake in Alberta, Canada, the project was shelved due to rising costs, added requirements, and the availability of longer-range aircraft and"
"addition, Mountbatten himself withdrew from the project. The final meeting of the Habakkuk board took place in December 1943. It was officially concluded that ""The large Habbakuk II made of pykrete has been found to be impractical because of the enormous production resources required and technical difficulties involved."" The use of ice had actually been falling out of favour before that, and other ideas for ""floating islands"" had been considered, such as welding Liberty Ships or landing craft together (""Project TENTACLE""). It took three hot summers to completely melt the prototype constructed in Canada. Perutz wrote that he stayed in"
"the system does not float away in a storm event or create a hazard. During World War II, the British Project Habakkuk proposed the construction of aircraft carriers made of ice-like Pykrete. Its size and speed made it more of an artificial iceberg or island than a ship. Commercial development of floating islands has begun taking place. Floating habitat islands were installed with salicornia salt marsh plants at Sydney Olympic Park Authority in 2011 providing nesting sites for local and migratory birds including black swans, black-winged stilts, red-necked avocets, Pacific black ducks and chestnut teals, using the Aqua Biofilter product."

Another project that Mountbatten proposed to Churchill was Project Habakkuk. It was to be a massive and impregnable 600-metre aircraft carrier made from reinforced ice (""Pykrete""): Habakkuk was never carried out due to its enormous cost. As commander of Combined Operations, Mountbatten and his staff planned the highly successful Bruneval raid, which gained important information and also captured part of a German Würzburg radar installation and one of the machine's"
"1942 he and Zuckerman served as scientific advisers to Lord Louis Mountbatten, the Chief of Combined Operations. Bernal was able to argue on both sides of Project Habbakuk, Pyke's proposal to build huge aircraft landing platforms in the North Atlantic made of ice. He rescued Max Perutz from internment, getting him to perform experiments on ice related to Habbakuk in a meat store freezer below Smithfield Meat Market. This project indirectly marked his divergence from Zuckerman, when he was recalled from a joint tour of the Middle East investigating the cooperation of army and air force, although the tour established"

Bernal and had been recommended to Lord Mountbatten, Chief of Combined Operations, by the Cabinet minister Leopold Amery. Pyke worked at Combined Operations Headquarters (COHQ) alongside Bernal and was regarded as a genius by Mountbatten. Pyke conceived the idea of Habakkuk while he was in the United States organising the production of M29 Weasels for Project Plough, a scheme to assemble an elite unit for winter operations in Norway, Romania and the Italian Alps. He had been considering the"

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 drawing board, but it was never produced. Unsinkable aircraft carrier An unsinkable aircraft carrier is a term sometimes used to refer to a geographical or political island that is used to extend the power projection of a military force. Because such an entity is capable of acting as an airbase and is a physical landmass not easily destroyed, it is, in effect,"

The tests confirmed that pykrete is much stronger than pure ice and does not shatter, but also that it sags under its own weight at temperatures higher than .

Churchill had discussed the Operation Jupiter with Franklin D Roosevelt on several occasions, and did so again on 27 July 1943. Churchill managed to keep the Jupiter idea alive, even suggesting that Project Habakkuk, a plan for a giant aircraft carrier made from a mixture of ice and sawdust, might solve the air cover issue. He managed to get Jupiter inserted into resolution of the Quebec Conference in"
"Perutz was rounded up along with other persons of German or Austrian background, and sent to Newfoundland (on orders from Winston Churchill). After being interned for several months he returned to Cambridge. Because of his previous research into the changes in the arrangement of the crystals in the different layers of a glacier before the War he was asked for advice on whether if a battalion of commandos were landed in Norway, could they be hidden in shelters under glaciers. His knowledge on the subject of ice then led to him in 1942 being recruited for Project Habakkuk. This was"

According to Perutz's own account, however, the incident of a ricochetting bullet hitting an Admiral actually happened much earlier in London and the gun was fired by someone on the project—not Mountbatten. Despite these tests, the main Project Habakkuk was never put into action because of limitations in funds and the belief that the tides of the war were beginning to turn in favour of the Allies using more conventional methods.

Perutz's work, inspired by Geoffrey Pyke and part of Project Habakkuk, was meant to test the viability of pykrete as a material to construct floating airstrips in the Atlantic to allow refuelling of cargo planes in support of Admiral the Earl Mountbatten's operations. The experiments were carried out by Perutz and his colleagues in a refrigerated meat locker in a Smithfield Market butcher's basement, behind a protective screen of frozen animal carcasses. These experiments became obsolete with the development of longer-range aircraft, resulting in abandonment of the project. At the end of the Second World War,"

The Habakkuk design received criticism, notably from Sir Charles Goodeve, Assistant Controller of Research and Development for the Admiralty during the Second World War. In an article"

As plans for the great ship evolved, it soon became apparent that the requirement for a freeboard could only be achieved with a hollow vessel: a solid mass of pykrete would have had an unfeasibly deep draft. Even so, a ship long and wide with thick walls would require a draft of and would displace 2,200,000 tons. Its construction, from an untried material, would be a quite staggering undertaking.

This caused the cost estimate to increase to £2.5 million. In addition, the Canadians had decided that it was impractical to attempt the project ""this coming season"".
