Northrop Grumman to build kits that convert 155-millimeter artillery shells into GPS-guided smart munitions
NEWARK, N.J. – U.S. Army explosives experts are asking Northrop Grumman Corp. to provide precision-guidance kits to transform conventional 155-millimeter artillery shells into GPS-guided smart munitions.
Officials of the Army Contracting command in Newark, N.J., announced an $40.6 million order last week to the Northrop Grumman Armament Systems and Ammunition segment in Plymouth, Minn., for M1156E4 precision guidance kits for the Army.
The Northrop Grumman precision guidance kit (PGK) transforms existing 155-millimeter high-explosive artillery projectiles into affordable satellite-guided precision weapons.
The PGK conversion kit uses signals from the Global Positioning System (GPS) to guide artillery shells to their targets with accuracy of less than 10 meters.
The low-cost reliable, fuze-sized guidance kit installs in the artillery shell's fuze well and also provides traditional fuze functions for height-of-burst and point detonation.
PGK conversion kit provides maneuver forces with precision capability that works in all weather conditions, and fills a gap between conventional unguided artillery and smart munitions.
On this contract modification Northrop Grumman will do the work in Plymouth, Minn., and should be finished March 2026.
