Between 1940 and 1996, the U.S. spent at least $8.75 trillion in present-day terms on nuclear weapons development, including platforms development (aircraft, rockets and facilities), command and control, maintenance, waste management and administrative costs.he United States is one of the five nuclear weapons states permitted to maintain a nuclear arsenal under the Nuclear Non-Proliferation Treaty, of which it was an original drafter and signatory on 1 July 1968 (ratified 5 March 1970).
