$8.2M to ARM for Marine Corps Smoke Grenades

66mm Smoke Grenade American Rheinmetall Munitions (ARM) in Stafford, VA received an $8.2 million order from the Program Manager for Ammunition, Marine Corps Systems Command, in Quantico, VA, to deliver vehicle-launched 66mm visual and infrared screening smoke grenades. The Marines chose the ARM’s red phosphorous smoke MK 1 MOD 0 grenade over the brass flakes-based M76 grenade. Both the MK 1 MOD 0 and the M76 are armored-vehicle-launched grenades that provide masking for armored vehicles in the visible and thermal infrared wavebands, so-called bispectral obscurants. The obscurants make it difficult for the enemy to detect the vehicles by blocking the electromagnetic spectrum. However, the grenades provide masking in different ways. The MK 1 MOD 0 grenade uses red phosphorous pellets and wafers that, when burned, generate a thick smoke the blocks detection of the vehicle in the visible and infrared spectrum. The M76 grenade uses micropulverized flakes of brass that when dispersed by the grenade also block the infrared and visible spectrum. ARM argues that its MK 1 MOD 0 grenade provides better protection for armored vehicles because the red phosphorous smoke provides longer lasting coverage than the brass flakes in windy conditions and the smoke is less toxic to […]
