ResheFuze AR175

Artillery Rocket Electronic Proximity Fuze

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

TECHNICAL SPECIFICATIONS
Open All

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.
