The M125 bomblet was a small U.S. chemical weapon designed to release sarin nerve agent. It was used with the M34 cluster bomb, the United States’ first air-delivered nerve agent weapon, which entered service in 1954. The M34 bomb carried 76 M125 bomblets, arranged in four groups. Each bomblet weighed about 10 pounds and contained sarin, an explosive charge, a fuze, and a parachute. The system had about 17 percent of its weight as agent, and it wasn’t the most efficient delivery method. Later, the military moved to spherical bomblets for wider coverage. In 1976, over 21,000 M125 bomblets inside M34 bombs were destroyed at the Rocky Mountain Arsenal.
