When the M46 is stacked in a 155 mm carrier projectile, (circular array of seven, one center row, all stacked 11 high) the central row has a spacer around it, assembled of two white nylon halve scales (180 degrees) that fills up te space between the outer circular array and the center row. With these French submunitions that are wider at the base, the submunitions fill the total internal diameter of the carrier projectile, therefore the spacer halves around the center row are not needed anymore, as well as most other spacers that can be left away. The only three longitudal rows of spacers required are the spacers that fall into the longitudal slots in the inside of the carrier projectile and prevent the submuntion package inside the carrier projectile from rotating compared to the projectile body.
