Bomb Nose Fuzes T32 (M118), T33 (M119) - Bomb Nose Fuze T32 was standardized as the M118 but has subsequently been destandardized to its previous T32 designation. The bomb Nose Fuze T33 has never been standardized. Neither of these fuzes is suit-able for Navy use.

Characteristics

Modification - AN-M120A1 differs from the AN-M120 only in requiring a shorter time to arm.

Status - AN-M120 - Obsolesent; AN-M120A1 - Service. A new fuze, the M170, is similar to the AN-M120A1 except that it requires a still shorter arming time (1.5 ± 0.3 sec.).

Restriction on Use - None. Because this fuze requires no air travel to arm and is ex-tremely sensitive when armed, extreme care should be taken when handling bombs con-taining this fuze. See page 8 for special precautions.

Air Travel to Arm - None required. AN-M120 arms by clockwork in 2.5 ± 0.3 sec. and AN-M120A1 arms in 1.9 ± 0.3 sec. after release of the arming pin.
