March Air Base's history traces back to the 1910s. It began as a fledgling air strip (which temporarily shut down), and came back to life in 1927. March Air Base became an important site during WWII as many pilots and crews did final phases of training there before deploying to the Pacific Theater. At its peak, the base supported approximately 75,000 troops. March remained active after the war and through the 1980s until its realignment began in 1993. By 1996, March had been designated a Reserve base.
