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.
