122mm 9M22 Grad Rocket for BM-21 grad multiple rocket launcher.
The 9M22 is the base model of the BM-21 Grad 9K51 series of 122mm rockets being a FRAG-HE fin-stabilised rocket with a steel tube body, a high-explosive (HE) fragmentation warhead in the front section and an electrically ignited rocket motor in the tail.
On the base 9M22 model the warhead is the M-21-OF containing 6.4kg of TAG-F high-explosive (HE) detonated by a 9A210 or MRV point-detonating (PD) fuze, which is inertially armed only after travelling some 150 to 400m from the launch point.
The warhead is double-skinned, with the outer skin only lightly scored, in order to avoid damaging its structural integrity during launch.
When detonated the internal scoring of the M-21-OF warhead creates approximately 3,150 fragments which are scattered over a lethal radius of about 28m.
