The warhead 9N51 (Fig. 99) consists of a steel case 4 with two bushings 8 of a corrugated metal sheet pressed into it, a bursting charge 7 with a detonator block 6 of tetril. Warheads are filled with  the composition A-IX-2  or TGAG-5.

From the side of the head cut, the body has an internal thread, into which the fuse 1 is screwed in and locked with a screw 5. The cylindrical part of the body has an internal thread for connecting to the body of the missile part. A plug 10 is screwed into the body of the warhead, which protects the explosive charge 7 from damage. A cardboard spacer is placed between the explosive charge and the plug.

On the ogival part of the body there is a cylindrical groove on which a brake ring 2 with a spring 3 (large or small) is put on.

A plastic plug is screwed into the threaded point under the fuse before bringing the projectile into its final form. The body of the warhead is painted with XB-124 gray enamel or wild gray oil paint.
