2.25-Inch Sub-Caliber Aircraft Rocket
The 2.25-Inch Sub-Caliber Aircraft Rocket, or SCAR, was an American unguided rocket developed by the United States Navy during World War II. Capable of simulating the aerial rockets then coming into operational service, the SCAR was used to train pilots in the use of the new type of weapon, and continued in service throughout the 1950s.
==Development==
With the introduction of the 3.5-Inch and 5-Inch Forward Firing Aircraft Rockets, a need arose to train aircraft pilots in the proper tactics for the use of the new weapons. This requirement resulted in the development of a dedicated training rocket by the U.S. Navy.〔Parsch 2004〕
Designated 2.25-Inch Sub-Caliber Aircraft Rocket, the resulting rocket was a joint project between the Bureau of Ordnance and the National Defense Research Committee.〔 As its name implied, the rocket was designed as a sub-calibre weapon compared to the FFAR, being only in diameter, but weighted to be ballistically similar to the larger operational weapons.〔 Varying the amount of propellant in the SCAR's motor could produce accurate simulations of either type of FFAR's flight characteristics.〔
