Once fielded to the warfighter, PGK will transform conventional 155mm artillery projectiles into a near precision weapon reliably reducing normal artillery dispersion of more than 200 meters to less than 30 meters. This transformation allows highly responsive and precise use of artillery on the modern battlefield.
The $120 million (USD), contract calls for the production, lot acceptance testing and delivery of the guidance fuzes for fielding to U.S. and select allied armies. Deliveries are scheduled to begin in early 2016 without a production break from the Low Rate Initial Production which began in January 2015.
“This contract signing marks another significant milestone for the PGK program. Fielding PGK for use with existing artillery projectiles provides soldiers with a distinct battlefield advantage by greatly reducing the inherent dispersion associated with conventional artillery. As a proven and qualified technology, the next step is growing PGK into future precision applications for either existing or new direct and indirect fire weapons systems,” said Dan Olson, Vice President and General Manager of Orbital ATK’s Armament Systems division of the Defense Systems Group.
PGK is a guidance fuze that fits within the fuze well of 155mm high-explosive artillery projectiles, performing in-flight course corrections to greatly reduce artillery dispersion. The Orbital ATK design features a fixed-canard guidance and control approach with gun-hardened electronics and a self-generated power supply. PGK performs all standard fuze functions while also incorporating a “fail-safe” option, preventing a PGK-equipped artillery round from detonating if it does not get close enough to the target.
Today’s battlefield is ever-changing in terms of terrain and engagement criteria. Reducing the risk of friendly and civilian casualties and collateral damage to infrastructure is critical. This combination of constraints often restricts ground commander’s options and sometimes limits use of artillery to engage critical targets.
PGK’s ability to reliably reduce artillery dispersion provides the warfighter a level of precision necessary to greatly reduce the risk of collateral damage and put artillery back into the fight.
Orbital ATK supplied PGK for use in Afghanistan for training and tactical operations via an urgent materiel release in March 2013. In December 2014, PGK passed First Article Acceptance Testing.
