Launch of a SAM-N-2 <i>Lark</i> missile at the U.S. Navy Naval Ordnance Test Station China Lake, California (USA). The program was stopped in 1950 in favour of the later RIM-2 <i>Terrier</i> missile. Modified <i>Lark</i>s were later used for guidance system development testing by all three U.S. services through the early 1950s. The U.S. Bureau of Aeronautics <i>Sparrow</i> program began in 1950 using the <i>Lark</i> target seeker in air-to-air missiles. The U.S. Army used <i>Lark</i> components investigating guidance options for the MGM-18 <i>Lacrosse</i> surface-to-surface missile. Changing roles during a period of changing nomenclature created a confusing number of designations for the <i>Lark</i>. Fairchild production was identified as KAQ, SAM-N-2, and CTV-N-9. Convair production was identified as KAY, SAM-N-4, and CTV-N-10. Army test versions were designated RV-A-22.
