Description

This cluster is similar to the M1. The components differ, but in function it is similar except in the incorporation of a delay cartridge of 5 seconds. This cartridge permits the cluster to drop for 5 seconds before opening. This delay is essential because the fuzes used with the fragmentation bombs in this cluster arm after several rotations of the arming vane. This delay permits the bombs to be well out of the range of the bomb fragments in the event that the bombs accidentally function in the air upon arming of the fuze.
