When steam propulsion began to be applied to warships, naval constructors renewed their interest in armor for their vessels. Experiments had been tried with armor during the Crimean War, just prior to the American Civil War,[15] and the British and French navies had each built armored ships and were planning to build others. In 1860, the French Navy commissioned La Gloire, the world’s first ocean-going ironclad warship. Great Britain followed a year later with HMS Warrior.[16][17] The use of armor remained controversial, however, and the United States Navy was generally reluctant to embrace the new technology.

Die Glocke (German for “The Bell”) is the name of a purported top secret Nazi scientific technological device. The only source for this is the books of Polish aerospace defence journalist[1] and military historian[2] Igor Witkowski, which claims it to be a secret weapon, or Wunderwaffe. The topic has been popularized by military journalist and author Nick Cook as well as by conspiracy theory writers such as Joseph P. Farrell. Farrell and others associate it with Nazi occultism and antigravity or free energy research. However, other researchers such as aerospace expert David Myhra view it merely as a rumor of a peculiar rocket design without a mystical background akin to the V-2 rocket program.[
