MC-1 bomb

[3] Umatilla Chemical Depot stored about 2,400 MC-1 bombs until the final one was demilitarized and destroyed on June 9, 2006.

[5] Those weapons were destroyed during the ensuing decade and operations at Johnston Atoll Chemical Agent Disposal System ended in 2000.

One goal was to determine hazards associated with the accidental release or damage from hostile fire of the MC-1 during takeoff or landing.

[7] A second goal was to determine if leak suppressant and disposal procedures for damaged bombs were adequate.

[7] For the purpose of the tests the MC-1 was filled with water and a sarin simulant, di(2-ethylhexyl) phthalate (DEHP).
