Description: |
---|
The 155mm Smoke WP, M110, and M110E1 projectiles consist essentially of a steel shell (casing) containing an M6 burster loaded with tetrytol running through the center of the shell, and an explosive filler of 15. 6 lb WP (white phosphorous). An adapter in the nose of the projectile is threaded to receive the fuze. For shipping and handling, a lifting plug is installed in the nose fuze cavity. A rotating band encircles the projectile case near the base and is protected by a grommet for shipment and handling, The grommet is to be removed before loading the projectile in the weapon. A PD fuze is normally used with these projectiles. Except for the WP contents, these projectiles are exactly the same as the projectile H/HD. M110, and the ballistics and configuration are the same as the HE, M107 projectile. |
Use: |
---|
These projectiles are fired from 155mm howitzers to produce screening smoke. The projectiles also have a slight incendiary effect. |
Functioning: |
---|
When the weapon is fired, the burning propellant charge generates rapidly expanding gases to propel the projectile through the barrel and to the velocity required to reach the target. The rotating band engages the barrel rotating band also provides a seal to prevent leakage of gas pressure past the projectile. When the fuze functions, the burster is detonated to rupture the projectile case and disperse the contents. White phosphorous ignites spontaneously upon contact with air and produces a dense white smoke. |
