Proximity fuse MK53 removed from shell, circa 1950s. A Proximity Fuse (also VT fuse [1] [2] [3] or "variable time fuze") is a fuse that detonates an explosive device automatically when it approaches within a certain distance of its target.
However, VT fuzes went far deeper into the shell than other fuzes because they had a battery that was activated by the shock of firing. This meant the fuze recess had to be deeper, so to enable shorter non-VT fuzes the deep recess was filled with removable supplementary HE canisters. After the war the next generation of proximity fuze included ...
M734 fuze cross section Amplifier (top) and oscillator. The M734 multi-option fuze [1] is a rangefinder and collision detection system used on 60 mm, 81 mm, and 120 mm mortar shells as a trigger to detonate the shells at the most damaging heights of burst when combating four types of battlefield threats:
An aerial shell loaded with many such pieces results in a myriad of pieces flying and sparking high in the air. A spolette is a delay fuse consisting of a hollow wooden dowel or a paper tube rammed full of black powder. A spolette is glued into the wall of a fireworks shell and ignited by the lift charge that launches the shell into the air.
The M982 Excalibur was fielded as a guided shell that effectively hit within 6 m (20 ft) of a target, but the Army developed the XM1156 as a cheaper alternative. The PGK fuse can be screwed onto existing M549A1 and M795 projectiles, be fired from M109A6 Paladin and M777A2 Howitzer artillery systems, and hits within 50 m (160 ft) of the target ...
In the United States and some military forces, [10] fuze [11] is used [12] [13] [unreliable source?] [14] to denote a sophisticated ignition device incorporating mechanical and/or electronic components (for example a proximity fuze for an artillery shell, magnetic/acoustic fuze on a sea mine, spring-loaded grenade fuze, [15] [16] [17] pencil ...
The three main parts of the rocket. The rocket consists essentially of three parts: The drive unit with the solid rocket fuel inside and four tail fins and two mounting devices with which the rocket is attached to the weapon carrier.
The technique involves a howitzer firing a high explosive (HE) shell using a mechanical time–super quick (MTSQ) artillery fuze set to cause an airburst over a target in very close proximity to the firing gun's position. Set properly, the shell would detonate approximately 10 meters (33 feet) above the ground at ranges of 200 to 1,000 m (660 ...
