NOTE
•
The M483A1 projectile may be fired with or without an
obturating band. If the obturating band is broken, remove and
discard it. If it is dislodged, remove or reposition it.
•
The M483A1 projectile consists of a steel body with aluminum
base and ogive containing an expelling charge and 88
shaped–charge grenades.
•
The M483A1 projectile can be used in the fire–for–effect mode
or the registration mode.
•
In the fire–for–effect mode, the expelling charge ejects the 88
grenades from the projectile during flight and they actuate on
ground or target impact. A shaped charged jet it expelled
downward while the body bursts into a large number of high
velocity fragments.
•
The jet is capable of penetrating approximately 2.75 inches
(6.99 cm) of homogeneous armor plate. Antipersonnel effects
are obtained by fragmentation of the body.
•
In the self–registration mode, the expelling charge is removed,
a projectile spotting charge is attached to the time fuze and
installed into the projectile. Functioning of the fuze detonates
the entire projectile over the target, permitting observation of
the projectile as it functions in relation to the target. The
spotting charge will cause the projectile to detonate all 88
grenades inside the projectile, causing high fragmentation in
the same manner as a standard high–explosive projectile.
•
The M483A1 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 series fuze.
