What project was a scientific effort led by Germany to develop and produce nuclear weapons during World War II, and was subject to the Norweigian heavy water sabotage to prevent it?
Norwegian heavy water sabotage The Norwegian heavy water sabotage (Bokmål: "Tungtvannsaksjonen" , Nynorsk: "Tungtvassaksjonen" ) was a series of operations undertaken by Norwegian saboteurs during World War II to prevent the German nuclear weapon project from acquiring heavy water (deuterium oxide), which could have been used by the Germans to produce nuclear weapons. In 1934, at Vemork, Norway, Norsk Hydro built the first commercial plant capable of producing heavy water as a byproduct of fertilizer production. It had a capacity of 12 tonnes per year. During World War II, the Allies decided to remove the heavy water supply and destroy the heavy water plant in order to inhibit the German development of nuclear weapons. Raids were aimed at the 60 MW Vemork power station at the Rjukan waterfall in Telemark, Norway.
Axis powers The Axis powers (German: "Achsenmächte" , Japanese: 枢軸国 "Sūjikukoku", Italian: "Potenze dell'Asse" ), also known as the Axis and the Rome–Berlin–Tokyo Axis, were the nations that fought in World War II against the Allied forces. The Axis powers agreed on their opposition to the Allies, but did not completely coordinate their activity.
