In the 1970s and 1980s, during the military regime, Brazil had a secret program intended to develop nuclear weapons.^{[1][2][3][4][5][6][7]} The program was dismantled in 1990, five years after the military regime ended. Brazil is considered to possess no weapons of mass destruction but does have some of the key technologies needed to produce nuclear weapons.^{[8][7][9][10]}

Brazil is one of many countries (and one of the last) to forswear nuclear weapons under the terms of the Non-Proliferation Treaty.^[11]
