The IDF Ground Arm has decided to complete the development process and initiate procurement in the context of the "precision artillery shell" project.
MAFAT, IMOD's Weapon System & Future Technological Infrastructure Research & Development Administration, had initially supported two primary projects involving the manufacture of precision guidance fuzes for artillery shells: the fuze designated "Top Gun" by IAI and the fuze designated "Silver Bullet" by Rokar, a subsidiary of the BAE Systems Group.
The fuze is intended to convert any "dumb" artillery shell into a precision-guided munition.
The idea behind the development effort was to convert "standard" artillery layouts, that are part of every military organization around the world, into systems possessing the ability to launch precision-guided munitions with an accuracy radius of ten meters, for a price that may be regarded as relatively inexpensive, so that ground forces may be able to afford the acquisition of the new measure.
In the case of the Silver Bullet fuze, the shell leaves the muzzle of the gun with the fins already deployed. The location data of the shell are continuously transmitted and picked up by a two-way antenna. The uploading of target data into the computer inside the fuze is accomplished through wireless communication.
The Top Gun fuze by IAI also passed a series of trials in previous years. In the Top Gun fuze, the fins are deployed after the shell has left the muzzle of the gun. They are identical in size and function much like the wings of an aircraft.
The IDF Ground Arm made a decision to acquire "a precision guidance fuze" and will select one of the options being offered.
Converting "dumb" artillery shells into precision-guided munitions can be a significant force multiplier for any artillery unit. Converting standard shells into precision-guided munitions will also make it possible to engage targets in densely-populated combat zones that characterize the modern battlefield, as concerns about hitting uninvolved parties – as was the case during Operation Protective Edge – will be minimized.
