IAI / MALAM Division general manager Jacob Galifat said: “Following years of challenging technological development effort and multiple resources, we witness a unique technology that has matured so it can be further customised for the operational requirements of IDF.

“This project has faced us with new technological challenges, including protecting the survivability of electronic and mechanical components in a difficult firing environment and miniaturisation of the entire avionics into the size of a fuse.”

IAI’s TopGun course correction fuse can accurately calculate its location in space and plan the optimal course required for the shell to engage with the predefined target.

It has been designed to convert standard artillery ammunition into a precision-guided weapon, which can be used for future warfare arenas, both in Israel and globally.

The fuse also facilitates the expansion of the task range allocated to artillery and the more efficient performance of artillery assignments, IAI stated.
