The MC-1 bomb was the first U.S. non-clustered air-dropped chemical munition. The MC-1 was first produced in 1959 and carried the nerve agent sarin.

History The MC-1 chemical bomb was first brought into regular mass-production in 1959. A modified general purpose demolition bomb, the MC-1 was the first non-clustered chemical munition in the U.S. arsenal.Smart, Jeffery K.

The MC-1 was designed to be delivered via U.S. Air Force aircraft.Mauroni, Albert J. Chemical Demilitarization: Public Policy Aspects, (Google Books), Greenwood Publishing Group, 2003 pp. 18-19, (). The MC-1 was never used against enemy targets.

Specifications The MC-1 was a munition. The weapon had a diameter of and a length of . The MC-1 was filled with about of sarin (GB) nerve agent. The MC-1 was designed to be air-dropped via the F-4 Phantom II and was unable to fit that aircraft's replacement, the F-16.Duke, Simon (Stockholm International Peace Research Institute).

Demilitarization operations Umatilla Chemical Depot stored about 2,400 MC-1 bombs until the final one was demilitarized and destroyed on June 9, 2006.Hendrickson, Bruce.

Another 3,047 MC-1s were stored at Johnston Atoll when demilitarization operations began there in 1990.Cashman, John R. Emergency Response Handbook for Chemical and Biological Agents and Weapons, (Google Books), CRC Press, 2008, pp. 107-08, (). Those weapons were destroyed during the ensuing decade and operations at Johnston Atoll Chemical Agent Disposal System ended in 2000."Chemical Weapons Destruction Complete on Johnston Atoll", (Press release), U.S. Department of Defense, November 30, 2000, accessed December 29, 2008.

Test involving the MC-1 Tests were conducted using the MC-1 from July-November 1971 at Dugway Proving Ground in Utah. The aim of these tests, which were part of Project 112,"Project 112/SHAD Fact Sheets ", Force Health Protection & Readiness Policy & Programs, The Chemical-Biological Warfare Exposures Site, accessed December 29, 2008. was twofold. One goal was to determine hazards associated with the accidental release or damage from hostile fire of the MC-1 during takeoff or landing. A second goal was to determine if leak suppressant and disposal procedures for damaged bombs were adequate. For the purpose of the tests the MC-1 was filled with water and a sarin simulant, di(2-ethylhexyl) phthalate (DEHP). The bombs were dropped from an F-4 during the tests."Fact Sheet — DTC Test 69-14 ", Office of the Assistant Secretary of Defense (Health Affairs), Deployment Health Support Directorate, accessed November 12, 2008.
