The Iceberg Aircraft Carrier: Churchill's Secret Plan to Build Warships Out of Frozen Water

from Weird History

In 1942, as Nazi U-boats threatened Britain's survival, Winston Churchill greenlit one of history's most outlandish military projects - building massive aircraft carriers made of ice. Project Habakkuk proposed creating unsinkable 2,000-foot vessels by mixing ice with wood pulp to create "pykrete," a bizarre material that was bulletproof, slow to melt, and could be repaired mid-ocean using seawater. The eccentric British inventor behind the plan famously demonstrated pykrete's potential by shooting a block of it in front of shocked Allied commanders - nearly killing an admiral with the ricocheting bullet. Engineers built a prototype on a Canadian lake, and the full-sized ships would have been larger than the Titanic, carried 200 aircraft, and had 40-foot thick hulls impervious to torpedoes. Discover why this seemingly absurd frozen fleet was seriously considered, how far it actually progressed, and why the massive ice ships never made it to battle against Hitler's submarines.Support the show here:https://www.paypal.com/paypalme/theAIwriter
