TM 9-2350-311-10 Table 5-1. 155MM AMMUNITION FOR M109 HOWITZERS - CONTINUED Authorized Projectiles Classification Identification Fuzes Remarks M864, HE, DP extended range, ICM — continued NOTE • The M864 projectile is modeled after the M483A1 projectile with the addition of a base burner unit at the projectile’s base. The propellant in the base burner ignites upon firing of the projectile, producing gases, which reduce the drag on the projectile and extend its range. • The expulsion charge contains 105 grams of M10 propellant. There are 72 shaped–charge grenades: 48 are M42 grenades and 24 are M46 grenades. • The M864 projectile can be used in the fire–for–effect mode or the registration mode. See the M483A1 description for mode differences. • The M864 projectile may be used for self–registration (as a spotting round) by replacing the expulsion charge assembly with a projectile spotting charge added to the M577 series or M762 fuze. • The M864 projectile is for extended range only and will be fired to achieve ranges beyond the capabilities of the M483A1 projectile or when the M483A1 projectile is not available.
