The 17th Antiaircraft Artillery Battalion was an antiaircraft unit in the United States Marine Corps that served during World War II.

History
Organization
The 2d Airdrome Battalion was commissioned on October 28, 1942 at Camp Elliott, San Diego, California. It was one of two airdrome battalions formed by the Marine Corps specifically to defend airfields in the China Burma India Theater. Those airfields were overrun by the Japanese before the battalions deployed so the Marine Corps quickly changed their tasking to missions in the Pacific Theater.While organizing and training in Southern California the battalion spent extensive time at Camp Dunlap in the Imperial Valley. The 2d Airdrome Battalion departed the United States near the end of May 1943 onboard the USS Henderson and SS Cape Clear.
The battalion arrived in Oahu, Hawaii on May 31, 1943. It remained there for a few months of additional training as it waited for its initial deployment orders. In early August the battalion embarked on the USS Ormsby and the SS Whistler and sailed west for the Ellice Islands.
Nukefetau and Tarawa
After a short layover in Funafuti, the 2d Airdrome Battalion arrived at Nukufetau on August 25, 1943 along with the first elements of the Navy's 16th Naval Construction Battalion. Nukufetau was a small atoll 75 miles northwest of the airfield that had been established on Funafuti. The battalion was responsible for air defense of the area while the Seabees constructed Nukufetau Airfield. The airfield was opened on October 6, 1943.Half of the 2d Airdrome Battalion was detached from duty on Nukufetau and sailed for Tarawa. The detachment went ashore four days after the 2nd Marine Division assulted the beaches. The remainder of the battalion departed Nukufetau in March 1944 after being relieved by elements of the 51st Defense Battalion. The 2d Airdrome Battalion sailed for Hawaii landing at Nawiliwili Harbor on March 21, 1944.
Reorganization and Tinian
The 2d Airdrome Battalion was redesignated as the 17th Defense Battalion on March 22, 1944 and assigned to the V Amphibious Corps. On April 19, 1944 it was again re-designated as the 17th Antiaircraft Battalion. In Hawaii they trained for the occupation and defense of small islands in the Pacific. Between June 10–18 the battalion departed Hawaii in three echelons. The unit spent the next 54 days at sea en route to their final objective. While anchored in the harbor at Eniwetok on July 19 the battalion's moniker was changed for the final time, this time to the 17th Antiaircraft Artillery Battalion.The 17th Defense Battalion landed on Tinian on August 2, 1944. They established positions north of the airfield and in the harbor. The battalion remained on occupation duty on Tinian for the next year. During these months they conducted routine patrols and took a number of Japanese prisoners of war still on the island after the battle. Three Japanese aircraft bombed and strafed the island on November 3, 1944 however the battalions batteries were not able to successfully engage any of the aircraft. The battalion was guarding the airfield on August 6, 1945 when the Enola Gay launched to drop the first ever nuclear weapon against Hiroshima in mainland Japan. On August 15, 1945 the 17th Antiaircraft Artillery Battalion was relieved of its tactical duties on Tinian. It finally departed the island on November 1, 1945 on the USS Griggs. The battalion sailed back to the United States and was officially decommissioned on December 6, 1945 at Marine Corps Base Camp Pendleton, California.
