DiamondBack is a TF-51 Mustang built in 1945 as a P-51D. After serving in the United States military from 1945 to 1958, the aircraft was sold to private owners in 1958. She raced from 1964 until 1993 under several names including the Reno racer "Stiletto" and won Unlimited Gold in 1984. DiamondBack was restored to a "stock" TF-51 Mustang in 1997.

Today, DiamondBack is owned by Mark Peterson and based in Boise, Idaho. She is available for static and flying displays at airshows and fly-ins.
