M1128 projectile

The M1128 "Insensitive Munition High Explosive Base Burn Projectile" is a 155 mm boosted artillery round designed to achieve a maximum range of 30–40 km. It is used for fragmentation and blast effect against personnel and/or materiel. The development of this round follows testing of (and is based on aspects of) boosted M795-series test projectiles. The M1128 is not yet in production, but the first successful test firings have already taken place.

The M1128 is expected to be compatible with a nose-mounted guidance system—specifically, the XM1156 Precision Guidance Kit, which fits the standard fuse threading common to several types of rounds.
