yes and no. they had an active program (lead by Werner Heisenberg) that started well before the Manhattan Project, but made several mistakes. British bombing and Norwegian partisan sabotage of the Norsk Hydro heavy water enrichment plant severely set the schedule back. this ultimately resulted in Albert Speer ordering the program scaled back before 1944 to only prototype reactor development with the intention of making power reactors after German won the war.
Note: there has been some suggestion that Heisenberg was not actually seriously working on the bomb, but only using the program to obtain draft deferments for promising German physicists. this cannot be confirmed however. if true though, some of the mistakes may have been partly intentional.
No, China has several hundred nuclear bombs and has had bombs since 1964.
Neither the US nor Russia are making nuclear weapons of any kind at this time. Other countries however are making nuclear weapons; some are North Korea, India, and Pakistan.
No
They used nuclear and atomic bombs.
Japan has no nuclear weapons.
Making more bombs or bigger bombs.
The U.S. began work on making nuclear bombs (atomic bombs) in WW2 out of fear that Nazi Germany might be working on them and use them to win the war, we needed to 1) determine if they could be made and 2) if they could try to make them before Nazi Germany did. After WW2 the U.S. continued making them and began work on hydrogen bombs out of fear that the USSR might attack the U.S. and/or western Europe.
They feared Germany had the technology to build nuclear bombs
Some bombs are nuclear. But most bombs are not nuclear.
For making the nuclear reactor and other items like the nuclear bombs and other stuff
Beacause millions of lives were taken by the nuclear bombs
No, China has several hundred nuclear bombs and has had bombs since 1964.
At this time the US builds no nuclear bombs. A small number of existing bombs are refurbished as needed.
Nuclear bombs before the 60s were referred to as atom bombs, because the term Nuclear hadn't been discover yet. Nuclear bombs today, are generally Hydrogen bombs, or fusion bombs. They are significantly more powerful, able to places about the size of Rhode Island. Atom bombs,which were mostly uranium and plutonium, lack the destructive power of Nuclear or Fusion bombs.
Yes, there is nuclear energy in nuclear bombs. It is released in a few microseconds when they are detonated.
Yes, nuclear bombs are real and have been developed and tested by several countries. These weapons derive their explosive power from nuclear reactions, which release enormous amounts of energy. The use of nuclear bombs is highly destructive and devastating, making them a major concern for global security.
Defense against the possibility that Nazi Germany might make one first.
