These great images from MCAS Beaufort, SC, showing a vintage squadron line up around an F4U Corsair, likely in WWII, and a newer image of a squadron with F/A-18 Charlies.
The unit in question is Marine Fighter Attack Squadron 312 (VMFA-312). Formed 1 June 1943 at Page Field, Parris Island, they fought at Okinawa and in the Japanese Home Islands then continued flying Corsairs off Jeep carriers in Korea. Flying Phantoms from 1966 through 1987, they switched to Hornets and haven’t looked back yet.
Their motto is “Fights on.”
