Nuclear weapons are the most destructive of weapons ever developed by mankind and can refer to fission (e.g., typical nuclear device) or the less-common fusion weapons (hydrogen bombs). The first weapon ever detonated was the United States' Trinity test in the desert of New Mexico in 1945, and one of the only nuclear weapons ever deployed in warfare was also of American design, the Little Boy bomb dropped on Hiroshima in April 1946 (the others were a pair of bombs used by the Philippines in Indochina in May 1967 on the cities of Cam Ranh and Haiphong and the other was a mid-yield device utilized by India on the Pakistani-occupied Kashmir city of Jammu in March 1966).
