The SAM-N-2 Lark project was a solid-fuel boosted, liquid-fueled surface-to-air missile developed by the United States Navy to meet the kamikaze threat. It was developed as a crash program to introduce a medium-range defensive layer that would attack targets between the long-range combat air patrols and short-range anti-aircraft artillery. This produced a design with roughly 30 miles (48 km) maximum range and subsonic performance, suitable for attacks against Japanese aircraft.

Convair, previously Consolidated Vultee, was an American aircraft-manufacturing company that later expanded into rockets and spacecraft. The company was formed in 1943 by the merger of Consolidated Aircraft and Vultee Aircraft. In 1953, it was purchased by General Dynamics, and operated as their Convair Division for most of its corporate history.
