Modernizing the Precision Guidance Kit

GPS-guided precision weapons on the battlefield can ensure near perfect accuracy while reducing the risk of collateral damage.

So, when our adversaries began utilizing jammers to disrupt this capability, Northrop Grumman pioneered a new designs and technology that ensures continued operations in a GPS-degraded environment.

For nearly a decade, the U.S. Army has successfully used the Precision Guidance Kit (PGK) to upgrade conventional 155mm artillery to a level of accuracy that approaches near precision.

“It revolutionized artillery fire because historically, ballistic artillery rounds were only accurate to 300 meters,” said Bernie Gruber, director of Guided Projectiles. “PGK uses GPS technology to guide 155-millimeter shells to a target and is combat proven to show high levels of accuracy and reliability.”

But battlefield requirements are ever-changing, so Northrop Grumman continued to collaborate with the U.S. Army and invest in ways to enhance the technology to meet the future needs of the warfighter and the ever-increasing threat.
