Fuzes AN-M158 and AN-M159 are vane operated and delay armed. They detonate the bomb instantaneously upon impact. The air travel (1,200 feet) necessary to arm fuzes AN-M158 and AN-M159 makes them suitable for use with land-based and and carrier aircraft. Fuzes AN-M158 and AN-M159 differ only in that the former has a booster containing 0.6 ounce of tetryl, whereas the latter has a smaller metal holder containing a column of tetryl. This difference in booster volume has resulted in a variance in fuze length. Fuzes AN-M158 and AN-M159 do not have safety blocks under the striker. In the unarmed condition, the striker is snug against the vane nut.
