A particularly successful application was the 90 mm shell with VT fuze with the SCR-584 automatic tracking radar and the M9 Gun Director fire control computer. The combination of these three inventions was successful in shooting down many V-1 flying bombs aimed at London and Antwerp, otherwise difficult targets for anti-aircraft guns due to ...
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 ...
Igniferous time fuzes had a powder ring in an inverted 'U' metal channel, the fuze being set by rotating the upper part of the fuze. When the shell was fired the shock of firing set back a detonator onto a firing pin, which ignited the powder ring; when the burn reached the fuze setting, it flashed through a hole into the fuze magazine, which ...
A magnetic proximity fuse was patented by P.J. Eliomarkakis, (United States Patent US2434551 of January 13, 1948) [1] although similar devices had been in service for nearly a decade. It is a type of proximity fuze that initiates a detonator in a piece of ordnance such as a land mine , naval mine , depth charge , or shell when the fuse's ...
An APKWS-equipped rocket was fitted with a proximity fuze and destroyed a Class 2 UAS. The proximity fuze enables it to intercept UAS at a lower cost than other methods, and due to the rocket's laser guidance that activates on launch it does not require locking on to the target before launch.

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:
It was calculated that a fuze which would explode a projectile near a plane or at some height above a target on the surface would increase lethality. Diamond, through his vast knowledge in the field of electronics, contributed greatly to the fundamental concept and design of proximity fuzes. He held 16 patents for electronics-related inventions.
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.
