Artillery Electronic Time Fuze

The RTN137 Electronic Time Artillery Fuze is highly accurate,
safe and reliable. Compatible with a wide range of calibers;
the RTN137 has an inductive time setting, as well a point
detonation that can be custom-set.


105mm – 155mm howitzers. Expelling mode (less booster): For smoke and illuminating projectiles. Detonating mode: For HE projectiles. For all charges, muzzle and terminal velocities.

Inductive setter operated, 3.0 to 199.5 seconds x 0.05 second increments.

Better than 0.1 seconds. Standard deviation time delay, less than 0.1 seconds.

Two independent arming mechanisms – Set-back force of 400g minimum; Spin rate of 1700 RPM minimum.

Expelling mode fuze: 258mg RDX. Detonating mode fuze: 27g CH-6 or A5.

Firing: From -40°c to +63°c Storage: From -46°c to +71°c

Overall length: Expelling mode fuze: 133.9mm max Detonation mode fuze: 151.6mm max Intrusion depth: Expelling mode fuze: 38.3mm max Detonation mode fuze: 56.1mm max Cross section diameter: 61.2mm Thread size: 2″-12 UNF-1A Weight: Expelling mode fuze: 0.70kg Detonation mode fuze 0.75kg

MIL-STD-331: Environmental and performance tests for fuze and fuze components. MIL-STD-333: Fuze, projectile and accessory contours. MIL-STD-1316: Fuze design, safety criteria. STANAG 4187: Fuzing system – safety design requirements.

Super quick function settable by inductive setter.
