The Museum maintains and restores vintage aircraft used by the United States Marine Corps (USMC) through work performed by employees and volunteers. Current restoration projects include an iconic World War II-era Douglass Dauntless SBD bomber. Restoration work has been done for the USS Midway Museum and Air and Space Museum in San Diego.
In the San Diego Aircraft Museum there are 27 aircraft currently on display, including “Lady Ace”, the helicopter that evacuated the U.S. ambassador from the rooftop of the embassy in Saigon on April 30, 1975. The museum includes a total of eight galleries, each full of artifacts from World War I to present. Highlights of these galleries include that exhibit Marines in Space and Women Marines. The museum also includes one of the world's largest collection of military patches.
