1:43rd ADA

The 1st Battalion, 43rd Air Defense Artillery Regiment (1-43rd ADA) traces its lineage back to the original 43rd Coast Artillery Regiment, constituted in 1918. Over the decades, the unit has participated in numerous key conflicts, including World War II, where it provided critical air defense in the Pacific Theater. Reactivated and redesignated multiple times, 1-43rd ADA has operated various air defense systems, most notably the PATRIOT missile system, providing protection against aerial and missile threats. Today, 1-43rd ADA continues to play a vital role in integrated air and missile defense, supporting U.S. and allied forces in regions such as the Middle East and the Indo-Pacific.
