U.S. defense contractor Northrop Grumman has reported successful deliveries of Precision Guidance Kit (PGK) units for the U.S. Army.

Here's What We Know

Northrop Grumman says the U.S. Army has received more than 100,000 Precision Guidance Kits for 155mm rounds. The manufacturer also stressed that it will continue to work on improving the PGK units to meet the Army's needs.

The Precision Guidance kit turns 155mm artillery shells into high-precision ones like the Excalibur. The kit is screwed into place of the fuse. And this procedure is done in the field without any special equipment.

After replacing the standard fuse with a PGK unit, a conventional projectile is transformed into a guided precision shot with a satellite guidance system. Northrop Grumman states that the deviation from the target is no more than 10 meters.


PGK has a very interesting history with four companies at once. The XM1156 debuted at the hands of Raytheon, the producer of the Excalibur high-accuracy missiles. However, the contract was awarded to BAE Systems.

At the same time, a third manufacturer, Alliant Techsystems Inc. was involved in completing the development of the PGK. In 2018 it was taken over by Northrop Grumman.
