'Tanker 48' built in 1961 and operated by Minden Air Corp. Now deployed here due to a high posibility that one of the forest fires in Arizona reach Ft. Huachuca!
Unlike other Yak-3 variants, the Yak-3U is fitted with a large radial engine, in an attempt to increase performance while avoiding the overheating problems of the VK-107 and VK-108 engines.
