Washington, September 23 (RHC)-- The United States plans to spend more than $1 trillion to revitalize its antiquated nuclear arsenal over the next three decades, according to a new report.

The Barack Obama administration has dedicated a "sprawling new plant" in Kansas City, Missouri -- bigger than the Pentagon -- to modernize "the aging weapons that the United States can fire from missiles, bombers and submarines," The New York Times reports.

The Kansas City National Security Campus is part of a "wave of atomic revitalization that includes plans for a new generation of weapon carriers," the report said. The new project, which will leave most of the U.S. nuclear arsenal intact, is in stark contrast to President Barack Obama's campaign promise in 2008 of "a nuclear-free world."

Instead, because of "political deals and geopolitical crises," the Obama administration is overseeing an extensive modernization of its atomic arsenal while implementing only modest arms reductions, according to The New York Times.
