As a response to his point #4 – Building something out of ice and wood pulp is far less complex and cheaper than building a ship made of steel. And in total war, it would have been made.

As for everyone else, over analysing the idea. There’s a reason why massive icebergs don’t melt after a week.

^^ This is the ice ship to which he is referring. Technically its not “ice” it's pykrete which is a mixture of wood pulp and ice. And yes the walls had to be about 40 feet thick according to the article.

“the Admiralty wanted it to be torpedo-proof, which meant that the hull had to be at least 40 ft (12 m) thick.”

2. It doesn't fucking matter if the Atlantic Ocean is cold, it's an ocean. The mere fact that it isn't all iced over would mean that the amount of salt in the seawater SURROUNDING the ship would cause all of that ice to melt. Also, testing a ship designed to withstand salt water [not to mention torpedoes and bombings from sea and air] in a FRESHWATER lake just makes absolutely no sense.

3. 35 FOOT THICK WALLS?! ARE YOU KIDDING ME? Even the best battleships of their day, along with all existing ships today, had armor roughly a foot thick; with an armor belt those would have been two feet at the very most, assuming they would have paired a thick wall with that thick of an armor belt.

4. No but seriously, 35 foot thick walls? And 4,000 feet long? Even the longest aircraft carrier ever built, the largest of supertankers on the earth today, max out at 1,500 ft.

This would mean the construction of a ridiculous machine on absolutely epic proportions; there's no way that a single letter of that is reasonable. Ice boats.. wonderful.

Also, you are all forgetting one of the strangest weapons ever created, and what I think is the most crazy sounding and successful weapon of WW2… The Bat Bomb. Which was basically a large bomb carrying thousands of Mexican-free tailed bats. After being released, the bomb (while still in the air) would deploy a shoot and release the bats. Attached to each bat was an incendiary bomb. After being released (in the daylight) the bats would fly from the original casing (activating the bomb timer) and the bats would take refuge in the dark places in rooftops. As the bomb was detonated, it would set buildings on fire. It was first used, quite successfully, on a mock Japanese village, to test its efficiency.

The Bat Bomb was set to be used in the event of an invasion of Japan. However, before it could be used, it was rendered obsolete with the completion of the Atomic Bomb.
