3MISSLE BATALION 21 ARTILLARY

The 3rd Missile Battalion, 21st Artillery (3-21 ADA), was an integral part of the United States Army Air Defense Artillery branch during the Cold War era. Originally constituted in the mid-20th century, the battalion was equipped with surface-to-air missile systems such as the Nike Hercules to protect critical areas from potential aerial threats. Stationed at various locations in the United States and abroad, 3-21 ADA played a vital role in strengthening NATO’s defensive posture in Europe. The unit’s mission focused on airspace defense until advancements in missile technology and changing strategic needs eventually led to its inactivation.
