United States Department of Defense, a state-owned entity headquartered in the US, was founded in 1949 and employs approximately 67,850 individuals. The department's primary function is to provide military forces to protect the U.S. and U.S. interests abroad.
On March 28, 2026, reports alleged that US Defense Secretary Pete Hegseth blocked the promotions of two female officers and two officers from ethnic minority backgrounds. Earlier the same day, CBS News, citing sources, reported that the US is running out of Tomahawk cruise missiles, having used over 100 against Iran, a quantity several times its annual production volume. Previously, on March 27, the US Department of Defense proposed a $65 million initiative to integrate PAC-3 MSE interceptors onto US Navy Arleigh Burke-class destroyers equipped with the Aegis combat system. Concurrently, forensic video analysis suggested that a US-made missile was used in a deadly strike on an Iranian town. This followed a March 27 report by the Washington Post, which indicated that the US military had fired over 850 Tomahawk cruise missiles in four weeks of war with Iran, a rate that alarmed some Pentagon officials and prompted internal discussions about missile availability.
