GPS jamming may no longer be enough to throw 155mm artillery off target, thanks to Northrop Grumman’s next-generation Precision Guidance Kit (PGK).
The PGK E5 upgrades the existing M1156 PGK with advanced anti-jam technology and improved guidance, fuzing, and control systems while retaining the original form factor.
It delivers first-round accuracy with a circular error probable of less than 30 meters (98 feet), helping reduce collateral damage while increasing the likelihood of hitting the target.
Designed for existing artillery systems and howitzers, the kit requires minimal equipment modifications or operator retraining, allowing units to field it more quickly.
The device also uses a NATO-standard deep-intrusion fuze to support compatibility across a range of platforms and 155mm projectiles.
During recent trials in GPS-degraded conditions, the PGK E5 reportedly exceeded both threshold and objective accuracy requirements.
“This solution shows how our integrated scale, expertise, and speed come together to deliver trusted, mission-critical capabilities that empower the warfighter,” the company stated.
Path to Fielding
Northrop Grumman worked with the US Army to shape the PGK E5 around operational requirements.
Production is now underway at the company’s facility in Plymouth, Minnesota, with initial deliveries expected in early 2028.
“Today’s threat environment demands speed and innovation, and we’re working closely with the US Army to ensure the PGK E5 keeps maneuver forces ready to win in GPS-degraded environments,” said Dave Fine, vice president of armament systems at Northrop Grumman.
“With decades of proven performance and growing production, PGK continues to deliver reliable, mission-ready technology that warfighters can count on.”
