| Description: |
|---|
| The projectile is a hollow steel forging with a streamlined ogive, gilding metal roating band, and pinned base plug. The projectile is assembled with an MTSQ fuze threaded into the nose of the projectile. The projectile cavity contains the expelling charge, illuminating canister, and parachute assembly. The expelling charge consists of 0.11 of black powder contained in a cloth bag. The illuminating canister contains the illuminate and 0.15 lb of first-fire composition. The parachute assembly is attached to the illuminating cansiter body. The base plug is inserted into opening at the base of the projectile and held in place by three shear pins and three twis pins. The complete projectile is free-fitted to a cartridge case. The cartridge case contains a percussion primer assembly and seven individually bagged and numbered propelling charge increments. The base of the cartirdge case is drilled and the primer assembly is pressed into the base. The percussion primer assembly consists of a percussion ignition element and a perforated flash tube containing black powder. The seven numbered increments bags are tied together, in numerical order, with acrylic cord. Thease are assembled into the cartridge case, around the primer flash tube, with Increment 1 at the base of the cartridge case and Increment 7 toward the mouth of the cartridge case. |

| This cartridge is intended for illuminating a designated target area. |
| Functioning: |
|---|
| If the projectile is unfuzed, both the closing plug and the fuze assembly to the projectile are removed prior to adjusting the charge and loading the cartridge into the weapon. Impact of the weapon firing pin result in the initiation of the percussion primer which, in turn, ignites the black powder in the flash tube. The flash tube provides for uniform ignition of the propelling charge producing a rapid expansion of the propellant gas which propels the projectile out of the weapon tube, Engagement of the projectile roating band with the rifling of the weapon tube imparts spin to the projectile providing inflight stability. The MTSQ fuze functions and ignites the expelling charge, and in turn ignites the first-fire composition. The expelling charge ejects the illumination canister and parachute assembly from the projectile by blowing off the base plug. Concurrently, the parachute deloys and infates, and the illuminant is ignited by the first-firing composition. Average luminosity is 450,000 candlepowder with a burning time of 60 seconds. |
