Hmm...what I see in the pic at the bottom looks like little to no delay, but I might be missing something else there. But looking back at some documentation, this is probably correct for the M1A2 cluster (6 frags). The M26 cluster (20 frags) could be fuzed for immediate separation from the cluster adapter occuring shortly after clearing the aircraft, or for mechanical time delay, with separation from the cluster adapter occuring after a specified period of time. Thus, setting a delay in the arming screen would affect separation from the cluster, not detonation of the individual frags on impact.
Quote:185. Cluster, Fragmentation Bomb, M26 Series
a. GENERAL. This series of clusters consists of the models M26, M26A1, and M26A2 and all contain twenty 20-pound fragmentation bombs. The Cluster M26 and M26A1 contain the AN-M41 fragmentation bomb and are shipped fuzed; the M26A2 contains the AN-M41A1 fragmentation bomb and is shipped unfuzed. The FUZE bomb, nose, AN-M158 is authorized for use in the bombs and FUZE, bomb, nose M110A1 (AN-M110A1) may be used in lieu of the AN-M158. This type cluster may be dropped for immediate opening or for delay opening. If delay opening is required, the cluster adapter must be fuzed with the mechanical time fuze M155. The cluster, which fits a 500-pound bomb station, is 52.56 inches long and weighs 416 pounds.
The three models differ as follows:
(1) The M26 consists of 20 fuzed fragmentation bombs AN-M41 assembled by means of the cluster adapter M13.
(2) The M26A1 consists of 20 fuzed fragmentation bombs AN-M41 assembled by means of the cluster adapter M13A1.
(3) The M26A2 consists of 20 unfuzed fragmentation bombs AN-M41A1 assembled by means of the cluster adapter M13A2.
b. FUNCTIONING.
(1) Delay opening. When released armed, the arming wire remains attached to the bomb shackle and is pulled out of the strap clamps and mechanical time fuze. No Fahnestock clips are used on the arming wire with mechanical time fuzes. The clamps remain closed because of the shear wires. At the expiration of the time set on the fuze, the fuze functions and drives the steel slug through the longitudinal member tube. This slug severs the shear wires which hold the clamps closed. The clamps then open and allow the bombs to be pushed out of the cluster adapter by the separator assemblies. Air stream arms the fuzes and the individual bombs detonate upon impact.
(2) Immediate opening. The mechanical time fuze is not used for immediate opening and the shear wires must be cut. When released armed, the arming wire is withdrawn from the clamps. They open and allow the individual bombs to be pushed out of the cluster adapter by the separator assemblies. Air stream then arms the fuzes and the bombs detonate upon impact.
