| Description: |
|---|
| The steel body of the projectile is fitted with a plastic obturator and seal, a threaded standoff spike assembly covered by an impact switch assembly (held in place with a collar), a tin and boom assembly and a point-initiating point-detonating fuze. A funnel-shaped copper liner within the body shapes the explosive charge of Composition B. A power supply retained by the impact to the spike assembly, switch assembly is fitted and is connected to the base-detonating fuze in the bod.y. The addition of the impact switch assembly provides for a higher functioning reliability in that initiation can occur upon contact with any part of the standoff spike assembly, i.e., improved performance on irregular surfaces and graze functioning. The fin is threaded to receive a tracer. |
| Use: |
|---|
| This cartridge is a high-explosive antitank cartridge and is intended for use on 105mm guns M68 against armored targets. |
| Functioning: |
|---|
| The electrically initiated primer ignites the propelling charge. Gases produced by the burning propellant propel the projectile from the gun and ignite the tracer which burns for a minimum of 2.5 seconds. Upon impact, fuze functioning detonates the projectile and the cone collapses, creating a high velocity focused shock wave and a jet of metal particles that penetrate the target. |
