Orbital ATK s Innovative Approach Transforms Existing Artillery
Projectiles
DULLES, Va.Jun. 29, 2015--
Orbital ATK, Inc. (NYSE: OA), a global leader in aerospace and defense
technologies, announced today that the U.S. Army's Precision Guidance
Kit (PGK) for 155mm artillery achieved another major program milestone,
having successfully completed its first production Lot Acceptance Test,
demonstrating a median accuracy of less than 10 meters and passing all
safety and reliability requirements.
Extensive, rigorous testing continues to prove the maturity of PGK
technology in terms of reliability, performance and safety, said Dan
Olson, vice president and general manager for Orbital ATK s Armament
Systems division of the Defense Systems Group.
Two additional Lot Acceptance Tests will confirm production consistency
while also populating a reliability database that provides information
which leads to product improvements over the course of production.
Our precision guidance expertise is making a difference across multiple
platforms for our customers, said Mike Kahn, president, Orbital ATK
Defense Systems Group. Accuracy translates to effectiveness, an
important factor in support of the warfighter.
PGK is a guidance fuze that fits within the fuze well of 155mm
high-explosive artillery projectiles and performs in-flight course
corrections that greatly increases accuracy. Orbital ATK s design
features a fixed-canard guidance 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 the
projectile from detonation if it does not get close enough to the target.
Orbital ATK has demonstrated that PGK commonality provides a scalable
and affordable precision capability for multiple conventional platforms.
Today s battlefield is extremely complex and continually evolving.
Reducing the risk of civilian casualties and collateral damage to
infrastructure is critical. These constraints can restrict the
battlefield commander s options and limit artillery use to engage
critical targets. PGK provides commanders with additional options to use
all the tools at his disposal to achieve victory.
Orbital ATK Defense Systems Group is an industry leader in providing
innovative and affordable ammunition, precision and strike weapons,
electronic warfare systems, and missile components across air-, sea-,
and land-based systems.
