The Department of Defense finalized agreements with Lockheed Martin and Northrop Grumman to increase output of Patriot PAC-3 and THAAD missile interceptors. The deals include a seven-year, $58 billion contract for Lockheed Martin that converts a prior one-year agreement and aims to triple Patriot and quadruple THAAD production. Officials cited the need to strengthen industrial supply chains for national defense requirements.
