M728 and M514 Series Variable Time Proximity Fuze

The M728 and M514 series fuzes are not to be used with the M203 and M203A1 propelling

charge.

The M728 and M514 series fuzes (8) are long intrusion proximity variable time (VT) fuzes used with deep cavity

projectiles and are essentially self-powered radio and transmitting units. The fuzes can be set from 5 to 100 seconds.

The nose of the M728 fuze has been painted black to reduce static electricity.

h. M732 Series

NOTE

The PD setting of the M732 series VT fuzes, when fired into soft impact areas, will produce less

lethality than the superquick setting of the M739 series PD fuze.

The M732 fuze (9) and M732A2 fuze (10) are proximity variable time (VT), short-intrusion fuzes of the same overall

length as the standard impact or mechanical time fuze. The supplementary charge must be left in the fuze well for

proper functioning of the M732 series fuze. The M732 series fuze has a time ring that can be set from 5 to 150 seconds.

The M732A2 fuze can be set from 4 to 156 seconds. Time settings are used to arm these fuzes 3 to 5 seconds prior to

set time for proximity function. The fuzes can also function PD as an option or proximity mode back-up and are always

armed for PD at 400 calibers, The M732A2 was especially designed for compatibility with rocket-assisted rounds. The

M732A2 is set by simultaneously depressing two pushbuttons (11) and rotating the setting ring to the desired position.

When the two pushbuttons are released, the setting ring is locked into position.
