US nuclear weapon plans to cost $355 billion over a decade - CBO report

WASHINGTON (Reuters) - The Obama administration's plans for the U.S. nuclear weapons complex, including modernization of bombs, delivery systems and laboratories, will cost the country about $355 billion over the next decade, the Congressional Budget Office said on Friday.

That is nearly $150 billion more than administration's $208.5 billion estimate in a report to Congress last year, an analyst at an arms control group said, and since the modernization effort is just beginning, costs are expected to greatly increase after 2023.
