Despite improvements over the P-39, the P-63 was inferior to other fighters and the vast majority of the 3,303 built were supplied to Russia. With its mid-mounted Allison engine exposed by a viewing panel, this Kingcobra dates back to 1943 when it was built for the USAAF, being sold to the Honduran AF in 1948. In 1960 it was repatriated as N9003R and ended up in open storage at Phoenix Sky Harbor Airport. In the early 1970s, now under the care of the USAF Museum, it was loaned to Pima and was painted in a Soviet scheme, before the restoration that saw it brought inside in the mid-1990s
