On this contract, Northrop Grumman will do the work at locations to be determined with each order, and should be finished by July 2027. forces must maintain in inventory, Army officials say. This multi-option capability reduces the number of artillery fuzes the U.S. MOFA incorporates a proven legacy safe-and-arm device to maintain required safety and reliability, and can be inductively set in the proximity, point detonating, delay, or time mode. They provide a more sophisticated trigger mechanism than the common contact fuze or timed fuze. Proximity fuzes are designed for targets such as planes, missiles, ships at sea, and ground forces. It employs state-of-the-art advanced electronic technologies, and replaces seven earlier fuzes to simplify logistics and training. A proximity fuze (or fuse) is a fuze that detonates an explosive device automatically when the distance to the target becomes smaller than a predetermined. A proximity fuze (or fuse) is a fuze that detonates an explosive device automatically when the distance to the target becomes smaller than a predetermined value. The M782 is the latest fuze artillery design and is compatible with all current 105- and 155-millimeter bursting artillery shells.

The proximity fuze screwed into the shell, with a portion fitting inside and the top portion forming the nose of the projectile.
#Proximity fuze portable#
The M782 fuze is remote-set automatically before firing via an inductive communication link like the TM 9-1290-210-12&P M1155 portable inductive fuze setter. It provides a more sophisticated trigger mechanism than the common contact fuze or timed fuze to increase artillery lethality by 5 to 10 times, compared to these other fuzes. This electronic ignition device detonates high explosive ammunition, above the ground, thus increasing the artillery system efficiency. The fuze is designated to initiate the warhead at the optimum height above the target providing. 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.Ī proximity fuze detonates an explosive device automatically to destroy or damage targets such as planes, missiles, ships at sea, and ground forces. The Proximity fuze AR-139 is a radio proximity fuze, utilizing the Doppler Effect. The AR-787 is Proximity fuze utilizing the Doppler Effect. The proximity fuze has four functional modes: variable time, time, point detonating, and delay.
