British Engineers Tested U‑Boat Hull Steel — Then Proved Allied Charges Were Enough

Описание: What happens when careful lab science meets wartime assumptions? In November 1944 at Teddington, British engineers tested captured U‑boat hull steel—and uncovered a surprising truth. The material showed far lower toughness under pressure than expected, helping explain why Allied depth charges were often sufficient against submarines in the Atlantic. This video breaks down the test methods, the metallurgy behind the findings, and what it meant for World War II naval operations.

You’ll learn:
How British metallurgists evaluated U‑boat pressure hull steel at the National Physical Laboratory
Why factors like notch toughness, weld quality, and temperature mattered at depth
Rated crush depth vs. real-world performance
Why Allied anti-submarine charges proved effective in practice
The engineering lessons that still apply today
