The Bell X-9 Shrike was a prototype surface-to-air, liquid-fueled guided missile designed by Bell Aircraft as a testbed for the nuclear-armed GAM-63 RASCAL.
It is named after the shrike, a family of birds.
Thirty-one X-9 rockets were delivered, flying from April 1949 to January 1953.
The program was used to gather aerodynamic and stability data, and to test guidance and propulsion systems for the RASCAL.
The only known remaining fragment of an X-9 is part of a vertical stabilizer, at the Larry Bell Museum in Mentone, Indiana.
