The 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-ranged 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.
