OVERVIEW: The KMG‑U dispenser loaded with PTAB‑1M submunitions is an air‑launched cluster munition system containing 248 anti‑tank bomblets. It is designed to engage armored and soft‑skinned vehicles through massed HEAT bomblet dispersion.

DETAILS: KMG‑U (КМГУ) stands for “Unified Container for Small‑sized Load” and is a Soviet‑developed aerial dispenser used on tactical aircraft and helicopters. The PTAB‑1M is a fin‑stabilized, shaped‑charge HEAT submunition weighing approximately 0.94 kg, with PIBD fuze and armor‑penetration capability of ≥200 mm RHA. Eight BKF‑PTAB‑1M cassette units, each with 31 bomblets, are loaded into the KMG‑U for a total of 248 submunitions. The dispenser open pneumatically and releases the bomblets, which are spin‑deployed to enhance area coverage.

FUNCTION: After release, the KMG‑U opens and disperses BKF cassettes. Each PTAB‑1M bomblet deploys fins, arms in flight, and on impact uses its shaped charge to penetrate vehicle top armor. The cluster design enables saturation over practical engagement areas for anti‑armor effects.
