During the 2012 presidential campaign, Romney proposed to increase the size of the military by at least 100,000 troops. He called for spending priorities that include an expanded Naval armada estimated at $40 billion. But he did not specify how he would pay for this spending under the current tight Federal budget. John Lehman, a top adviser, said that the shipbuilding funds would come from cuts in the Pentagon. Romney said he would extend Obama administration's current plans of building two attack submarines a year to three submarines a year, and would split the current co-production of submarines into two independent operations.
