The fuze circuitry produces a lobe pattern. It
radiates a pattern at right angles (fig. 1-16) to the
longitudinal axis of the weapon.
When the Mk 43 is initiated by the conventional
method, fuze functioning occurs instantaneously when
a firing pulse is received from the thermal battery. If the
alternate method is used (striker rod), the fuze is set for
either of the two functioning delays—DLY 1 for
0.015-second delay or DLY 2 for 0.100-second delay.
Detonation of the bomb is delayed by either 0.015
second or 0.100 second, depending on the delay that is
selected.

M20 AND M20A1 SENSING ELEMENT
PROXIMITY FUZE
The M20 is identifiable by the tan color of its plastic
nose cone. The nose cone of the M20A1 is brick red.
