General

An up-scaled revision of 115mm 3BM-6 APFSDS round, the 3BM-9 was the first APFSDS round fielded for the 125mm D-81T gun. With a unitary penetrator of maraging steel, large full caliber stabilizing fins, and poor performance involving angled impacts, the round offers only modest penetration despite its high muzzle velocity. Relegated to practice and trial use only, the 3BM-9 round was supplied to users of the export T-72M and produced under license in several countries.
