March Field (today’s March Air Reserve Base, located immediately adjacent to the March Field Air Museum) is the West Coast’s oldest continuously operating military airfield - and a birthplace of the modern Air Force. Established in 1918 as the U.S. was embroiled in World War I, it began life as part of the U.S. Army Signal Corps. Following several sleepy years in the 1920s, March Field was expanded in the 1930s as the world again prepared for war. As March Field passed the quarter-century mark, it was busily protecting West Coast skies and training U.S. Army Air Forces personnel for deployment to all Combat Theaters during WWII. Following the war—as the Cold War began—and then continuing for nearly 50 years, March Air Force Base became the U.S. Air Force Strategic Air Command 15th Air Force headquarters and home to a massive nuclear deterrent force.
In 1993, as March Field celebrated its 75th anniversary, it was selected for realignment and subsequently re-designated March Air Reserve Base. Today March Field is home to the Air Force Reserve Command’s 4th Air Force Headquarters and the 452nd Air Mobility Wing, the largest air mobility wing of the 4th Air Force. In addition to multiple units of the Air Force Reserve Command, March ARB is also home to units from the U.S. Air Force, Army Reserve, Navy Reserve, Marine Corps Reserve, California Air National Guard, California Army National Guard and the Department of Homeland Security. As it begins its second century as a military airfield in 2018, March Air Reserve Base is expanding to encompass new missions in service to, and in protection of, our great nation.
