1:55th ADA

• Origins in World War II: The 1st Battalion, 55th Air Defense Artillery (1/55th ADA) traces its lineage back to the 55th Coast Artillery Regiment, activated in 1918 and later reconstituted during World War II for anti-aircraft duties. • Coast Artillery Roots: The unit originally served as part of the Coast Artillery Corps, manning coastal defenses and anti-aircraft batteries to protect strategic locations in the US and overseas. • Redesignation and Modernization: The 55th was redesignated multiple times, reflecting changes in military doctrine—from coast artillery to anti-aircraft artillery, and eventually to air defense artillery in the 1950s. • Nike Missile Era: During the Cold War, elements of the 1/55th ADA operated the Nike Ajax and Nike Hercules missile systems, providing a vital layer of air defense against potential Soviet bomber attacks. • Vietnam War Service: While not deployed as a whole unit, members of the 55th ADA served in Vietnam, providing critical air defense and artillery support. • European Deployments: The battalion was stationed in Germany during the Cold War, helping to protect NATO allies from air threats with advanced missile systems. • Operation Desert Storm: In the 1990-1991 Gulf War, 1/55th ADA elements participated in air defense operations, protecting coalition forces from Iraqi Scud missile attacks. • Patriot Missile System: The battalion transitioned to the Patriot missile system, becoming a key part of America’s modern air and missile defense capability. • Distinctive Unit Insignia: The 55th ADA's insignia features a red shield and a gold artillery shell, symbolizing its artillery heritage and mission to "Guard the Skies." • Deactivation and Legacy: While the 1/55th ADA has undergone periods of inactivation and reactivation, its lineage and honors continue to be carried by successor air defense units in the US Army.
