The 2nd Battalion, 59th Air Defense Artillery Regiment (2/59th ADA) traces its origins to the 59th Coast Artillery, which was constituted in the early 20th century to provide coastal defense. During World War II, the unit participated in the defense of the Philippines and saw action during the Bataan campaign. Reactivated during the Cold War era, 2/59th ADA was stationed in Europe, where it provided air defense coverage as part of NATO forces, operating systems such as the HAWK missile. The battalion was eventually inactivated as part of post-Cold War force reductions, but its legacy continues through the lineage of the 59th ADA Regiment.
