155-mm HE-ER (High-Explosive Extended-Range) base-bleed projectile
The 155-mm HE-ER (High-Explosive Extended-Range) base-bleed projectile is operated primarily for blast and fragmentation against infantry troops and soft materiel targets.

This projectile can be fired from 39, 45, 52 -calibre 155-mm artillery guns using all types of propelling charges. The increased range is achieved by using a low-drag aerodynamic shape coupled with base bleed technology.
The projectile contains 12 kilograms of TNT in a thin-walled, high-strength, high-fragmentation steel- alloy body.

It has a deep-cavity fuze design that accepts Point-Detonating (PD) or proximity (VT) fuzes.

An aluminium liner in the deep fuze cavity contains a supplementary TNT charge. When proximity fuze is fitted, the supplementary charge is removed.

When a PD fuze is used, it detonates the supplementary charge upon impact, which in turn detonates the projectile filler. When a proximity fuze is used, detonation occurs when the projectile approaches the target (proximity action). The proximity fuze contains its own booster element to detonate the projectile filler.
