WASHINGTON — The Obama administration is weighing options for sharp new cuts to the U.S. nuclear force, including a reduction of up to 80 percent in the number of deployed weapons, The Associated Press has learned.

Even the most modest option now under consideration would be an historic and politically bold disarmament step in a presidential election year, although the plan is in line with President Barack Obama's 2009 pledge to pursue the elimination of nuclear weapons.

No final decision has been made, but the administration is considering at least three options for lower total numbers of deployed strategic nuclear weapons cutting to: 1,000 to 1,100; 700 to 800, and 300 to 400, according to a former government official and a congressional staffer. Both spoke on condition of anonymity in order to reveal internal administration deliberations.

The potential cuts would be from a current treaty limit of 1,550 deployed strategic warheads.
