| Description: |
|---|
| The M74 consists of a rocket warhead containing approximately 1.3 pounds of TPA, a base detonating (BD) fuze and an adapter which adapts the rocket motor to the warhead. The rockets are issued in four round clips. |
| Use: |
|---|
| The M74 incendiary thickened triethylaluminum (TPA) is used to defeat or neutralize hard, soft, or jungle targets |
| Functioning: |
|---|
| When the projectile is fired, acceleration acts upon the fuze sequential leaf arming mechanism. The fuze rotor assembly is then free to rotate to the armed position. When the rotor is in the armed position, the detonator is alined with the remainder of the explosive train. Rocket deceleration, due to impact, causes the graze element of the fuze to shift, thereby allowing the firing pin of the fuze to be driven into the primer. The primer flashes through the flash channel and initiates the detonator, then the trademark in the warhead; disseminating the warhead agent. |
