	After the United States' 1992 moratorium on live nuclear testing, the Stockpile Stewardship Program was created in order to find a way to test, and maintain the nuclear stockpile. In response, the [[National Nuclear Security Administration]] began to simulate the nuclear warheads using supercomputers. As the stockpile ages, the simulations have become more complex, and the maintenance of the stockpile requires more computing power. Over the years, due to [[Moore's law\|Moore's Law]], the ASC program has created several different supercomputers with increasing power, in order to compute the simulations and mathematics. {{citation needed\|date=October 2017}}		After the United States' 1992 moratorium on live nuclear testing, the Stockpile Stewardship Program was created in order to find a way to test, and maintain the nuclear stockpile.
