3UOF19-1 replaces the conventional point-detonating fuse of the 3UOF19 with a proximity fuse. The new 9E154 fuse is designed to detonate the shell at an altitude of around 3 meters above the ground, enabling it to defeat targets located behind cover or entrenched in foxholes or reinforced trenches. Thanks to the large casualty area produced by the airbursting effect, it is particularly useful when engaging hidden problematic targets such as ATGM teams or snipers. It becomes somewhat useless against IFVs, however, as the fragments are not nearly heavy enough to defeat even the thinnest roof armour, seeing as most IFVs are designed to withstand 155mm artillery air burst fragments. The proximity fuse also gives this shell the ability to engage moving aerial targets, as a direct hit is no longer necessary to achieve the desired effect.
