Republicans on the House Appropriations Committee are making significant cuts to an ambitious Pentagon goal to ramp up production of missiles as it seeks to arm Ukraine while preparing for a potential conflict with China.

Appropriators exacted more than $2.5 billion in reductions to sections of their Pentagon spending bill that deal with missile procurement across the military services, according to a draft committee report obtained by POLITICO that includes funding tables to accompany the legislation.

The shift in funding to other accounts by the influential spending committee is a blow to a major pillar of President Joe Biden’s defense plans laid out in his most recent budget proposal. Billions of dollars worth of weapons poured into Ukraine, forcing military planners to reconsider how it buys munitions to be prepared for another conflict. The result was a first-ever request by the Pentagon for Congress to fund multiyear purchases of munitions in a bid to kick production into high gear to be ready for a future fight.
