2.25-Inch SCAR

The 2.25-Inch SCAR (Sub-Caliber Aircraft Rocket) was a family of air-to-ground training rockets used for air-to-ground rocket firing practice by fighter-bomber pilots in the 2nd World War. The SCAR was developed by the National Defense Research Committee (NDRC) and the U.S. Navy's Bureau of Ordnance.

The rockets were similar to the 3.5-Inch and 5-Inch FFARs (Forward Firing Aircraft Rockets), but used a solid-propellant rocket motor of only 2.25-inch diameter (hence the "sub-caliber" name). By varying the amount of propellant, the flight characteristics of different FFAR types could be approximated.
