1 A premier aerospace and defense company 44 th Annual Gun & Missile Systems Conference & Exhibition Kansas City, Missouri 9 April 2009 PGK Precision Guidance Kit Affordable Precision for Future Artillery Doug Storsved Chief Systems Engineer ATK Advanced Weapons Approved for Public Release, POA 29-09, dated 24 Oct 2008,22 CFR 125.4(b)(13) applicable PGK Approved for Public Release, Precision Guidance PAO Kit #291-09, 22 CFR 125.4(b)(13) applicable Slide 1

2 Types of Precision s 100 X 10 X Current Paradigm: Order of magnitude cost increase from: Unguided to Precision Precision to Autonomous Non-Precision Precision Precision Guided Precision Smart Non-Precision (Area) /submunitions subject to all ballistic conditions on the way to the AIMPOINT. Precision Kits corrects for ballistic conditions using guidance and control up to the AIMPOINT or submunitions dispense with terminal accuracy Precision Guided senses guides coded to energy TARGET reflected with <10m from a target accuracy and uses delivering guidance and control to the unitary TARGET. or submunition A laser warhead. designator Submunitions in the loop is are required subject for to target ballistic conditions designation. to the AIMPOINT. No inertial navigation or Precision Smart /submunitions autonomously searches, detects, classifies, selects, and engages TARGET(s). Has a limited target discrimination capability. 1 X Mortars Artillery (Cannon, Rocket) Air-Delivered s 120mm Mortar Ammunition 105mm/155mm Cannon Fired Artillery Ammunition Relative Cost 1X 3-5X ~10-100X ~100X 120mm M934 XM395 PGMM Unguided 155mm 155mm GPS-Guided PGK XM982 Excalibur 1a (100X) 221mm Rocket-Launch Artillery Ammunition 178mm Rocket-Launch Artillery Ammunition 105mm GPS-Guided PGK XM982 Excalibur 1b (30X) GMLRS - Guided Multiple-Launch Rocket System (>100X) PAM - Precision Attack Slide 2

3 Precision Guidance Kit (PGK) Operational Benefits Transforms existing artillery inventory into affordable precision weapons Improves combat effectiveness Reduces collateral damage Reduces logistics footprint What is PGK? GPS Guidance Kit with Fuzing Functions Replaces the standard 155mm artillery projectile fuze PGK GPS guidance greatly improves the accuracy of conventional artillery in the inventory <50m CEP vs. >200m CEP at max range Maintains >90% of range capability of conventional projectile Requires no battery Has no one-shots or canard deployments Reliable - one moving part Uses COTS inertial sensors Full 2D Guidance to Impact Slide 3
