US Navy sailors man a light anti-aircraft gun mount, likely a 20mm Oerlikon cannon, aboard a WWII-era vessel. Crews like this stood ready around the clock to defend ships from air attack, particularly during the Pacific campaigns when kamikaze and enemy aircraft threats were constant. Though this photograph was originally associated with the escort carrier USS Petrof Bay, further review indicates the vessel pictured is not confirmed to be that ship, and its precise identity remains unverified.
