USS Valley Forge (CV-45)
Crewmen use flight deck tractors with power brooms to sweep snow from the carrier's flight deck, during operations off Korea, circa early 1951.
Photo is dated 8 May 1951, but Valley Forge ended her second Korean War deployment in late March of that year.
Plane parked in the foreground is a F4U-4 "Corsair" fighter. Those on the forward flight deck are an AD "Skyraider" attack plane and a HO3S helicopter.
