Precision Guidance Kit (PGK) technology is state of the art and provides a first-of-its-kind capability. PGK contains a Global Positioning System (GPS) guidance kit with fuze functions and an integrated GPS receiver to correct the inherent errors associated with ballistic firing solutions, reducing the number of artillery projectiles required to attack targets. The increase in efficiency that PGK’s capability provides allows operational commanders to engage assigned targets and rapidly achieve desired effects while minimizing collateral damage. PGK currently has two Department of Defense Identification Codes (DODIC), NA28 and NA29. The 2,399 kits that were procured for early fielding under an Urgent Materiel Release to Operation Enduring Freedom have the NA28 DODIC. The PGK currently being procured has the NA29 DODIC. PGK is also developing an increased capability in a GPS-degraded environment and will be compatible with the future M-Code GPS architecture.


PGK provides improved fire support to the maneuver force commander through effectively reducing target delivery error of conventional artillery munitions, and reduces the number of projectiles required to execute a fire mission.

The next generation PGK-AJ (anti-jam) will contain new technology that modernizes PGK. Additionally, PGK-AJ will provide compatibility with developmental artillery projectiles and platforms to achieve the Long Range Precision Fires Cross Function Team goals of lethality at extended ranges.


  • Demonstrated accuracy: Less than 20 meters circular error probable
  • Compatible with the M795 and M549A1 155 mm high-explosive projectiles
  • Mission-critical flight data is inductively loaded into PGK using the Enhanced Portable Inductive Artillery Fuze Setter


3QFY16: Full Rate Production Decision
2QFY19: 28 consecutive production Lot Acceptance Tests completed to date


FY19-beyond: On-going Tech Maturation and Risk Reduction (TMRR) in support of material solutions for PGK-AJ and transition to Engineering and Manufacturing and Development (EMD).
