Description
Electronic Time (ET) Fuze M767 Series is used with fragmentation (HE loaded) and burster type 105mm cartridges and 155 and 8-inch projectiles. The M767A1 fuze is not authorized for use with 8 inch projectiles.
The fuze contains an electronic timing system that may be set to function from 0.5 to 199.9 seconds in increments of tenths of a second. When used with weapons equipped with auto-setters, the fuze will be automatically remote set prior to launch via an inductive communication link between the fuzed ammunition and the weapon fire control system. The fuze can also be set via inductive communication link with a portable hand-held fuze setter. In addition, the fuze can be hand set (without the need of any tool) by rotating the OGIVE while depressing a thumb operated selector and cocking button until the desired time appears in the liquid crystal display (LCD) window. The ogive of the M767A1 can be rotated bidirectionally to provide quicker manual setting. The fuze is powered by a reserve lithium battery.
In the time mode, overhead safety is provided by an S&A that arms at 50 milliseconds prior to set time. When set for PD, the fuze is armed at 0.5 seconds in flight.
The M767A1 functions the same as the M767 but contains improved capabilities. The fuze ogive can be rotated bi-directionally to provide quicker manual setting. The LCD readout for PD is simplified to diminish the probability for manual setting errors. A battery bleed-down circuitry is added to facilitate render safe procedures. The fuze electronics is improved to provide more robustness in the operational environment and faster power on rise time for quicker response to autoset commands. The fuze can be passively interrogated by an autosetter to ascertain battery status and previously loaded setting data. For the M767A1, the booster pellet composition is changed from Comp A5 to PBXN-5.
