How did World War 2 submarines work?

World War II submarines were basically surface ships that could travel underwater for a limited time. Diesel engines gave them high surface speed and long range, but speed and range were severely reduced underwater, where they relied on electric motors powered by relatively short-lived storage batteries.

How successful were British submarines in ww2?

British submarines fought a deadly battle with their German counterparts during World War Two. The British submarines succeeded in sinking 12 German U-boats, for the loss of 4 of their own (P-615, Spearfish, Thristle and Doris) to U-boats.

What did submariners eat in WW2?

Meat, vegetables (mainly potatoes), bread and fruits were the basic ingredients in the submariners’ menu on German U-Boats during World War 2. While long-distance German U-Boats were excellent killing machines, habitability ranked very low on their designers’ priority list.

More important, American submarines contributed to the virtual strangling of the Japanese economy by sinking almost five million tons of shipping—over 60 percent of the Japanese merchant marine. Victory at sea did not come cheaply.

How do submarines work?

The submarine can travel with great agility, guided by a gyro and propelled by steam (generated by passing water through burning alcohol). Torpedoes can carry 500 pounds of TNT, to explode either directly upon striking the target or detonated by the influence of the magnetic field of the target’s hull.
