| Description: |
|---|
| The grenade consists of a rubber cylindrical body and a metal base. The rubber body contains 360 grams of red phosphorous/butyl rubber in a 95/5 proportion and a central plastic burster tube containing a burster charge of 15 grams of black powder. The metal base contains the electrical clips, F92 squib type electric fuze, propellant charge (3.0 grams of black powder), and the delay assembly with delay composition (0.26 grams of black powder). The metal base contains eight gas propulsion holes covered by a metal foil diaphragm. |
| Use: |
|---|
| Used with the M239 and similar Grenade Launchers to provide a self-screening smoke capability for armored/tactical vehicles. |
| Functioning: |
|---|
| The L8A1 grenade is propelled from the launching device when electrical current at the firing clip activates the electrical squib type fuze which ignites the propellant charge and simultaneously ignites the delay composition. Pressure builds up in the metal base, escapes through the propulsion holes and propels the grenade from the launching device. During flight of the grenade, the delay composition burns for approximately 3/4 of a second and ignites the burster charge. The burster charge ignites the red phosphorous/butyl rubber smoke composition and ruptures the rubber grenade body. The ignited smoke composition disperses to produce a white smoke cloud within 2 to 6 seconds after firing at approximately 98 feet (30 m) from the launching device. |
