Escalating tensions with Iran have heightened concerns over U.S. weapons stockpile shortages and capability gaps, prompting the Pentagon's second-in-command to call on major American defense contractors to accelerate the production and delivery of critical weapon systems.

Deputy Secretary of Defense Steve Feinberg stated that the department is pushing to expedite or expand procurement of key programs, including wide-area surveillance systems, air defense sensors and interceptors, as well as missile tracking systems. "Multi-year development cycles are unacceptable," Feinberg wrote in an August 5 letter to top defense firms such as Boeing, Lockheed Martin, and RTX Corporation. "We must immediately and significantly compress program timelines and expand production capacity."

Feinberg's letter highlighted specific needs, including satellite communications and next-generation air defense systems. Another priority is Lockheed Martin's "Next Generation Interceptor" program, aimed at helping the U.S. defend against intercontinental ballistic missiles. This new interceptor will replace the existing warheads currently deployed in missile defense systems in California and Alaska.

He requested that companies submit proposals by the end of August, detailing how they would support the listed key programs through "more aggressive delivery schedules and/or increased production capacity." The memorandum to industry outlined critical projects considered for "accelerated development or increased procurement" in the upcoming Fiscal Year 2028 defense plan. These projects primarily focus on sea-based and land-based radar systems, aimed at enhancing missile defense capabilities, rather than adding specific missiles for strikes against Iran.
