Скачать или смотреть America Had No Radar Tubes in 1940—So Bell Labs Invented Vacuum Electronics That Changed Air Warfare

When America entered WWII, we had a devastating problem: no radar tubes capable of fighting a modern air war. While the RAF battled for survival over Britain in 1940, Bell Labs engineers raced against time to master vacuum tube technology that didn't yet exist. This is the untold story of how a team of scientists in New Jersey invented microwave electronics that could detect bombers through darkness, hunt submarines in the Atlantic, and guide the D-Day invasion—turning the tide of WWII before most people knew radar existed. From burning Hurricanes over Dover to factory floors producing thousands of magnetrons daily, discover how American innovation weaponized physics and changed warfare forever. The Battle of Britain, the Atlantic campaign, and the strategic bombing offensive all depended on this one breakthrough. This is their story.
