The AR175 is a Radio-Operated Proximity Fuze. This fuze
initiates the artillery rocket warhead above the target,
thus maximizing its effectiveness.

COMPATIBILITY
To be used with: high explosive (HE) warheads. The basic fuze is the
same for all calibers. Mechanical and explosive adaptors define the fuze
for each application.
OPERATION MODES
Proximity (PRX): Detonates the warhead at optimum height above the
target. Point detonating (PD). Also back-up on proximity mode.

POWER SUPPLY
Air driven (turbine) alternator.
ARMING
Arming of the fuze occurs only after two independent conditions
are sensed:
• Set-back force for a minimum duration.
• Sustained air flow.
