HELLFIRE Mod-K
Objective: Develop a Fragmentation Sleeve for Hellfire II Missile to Meet Urgent Operational Necessity
Objective: Develop a Fragmentation Sleeve for Hellfire II Missile to Meet Urgent Operational Necessity
Successful Fielding Resulted in Continuing Requests
Successful Fielding Resulted in Continuing Requests
• Development Concept– External Modification to
Current Fielded Missile System
– Ability to Modify Missiles and Containers in Field Locations
– Minimize Logistics Impact
– Ability to Ship Modified Missiles
– Field in Four Months
Purpose of the Program
• Add An Anti-Personnel / Anti-Material Capability for Hellfire Missile System
– Optimize Fragment Lethality Against Broad Range of Targets
– Minimize Shaped Charge Performance Degradation
– Meet Urgent Operational Necessity
– Mission Capable – Limited Qualification
Elements of Design
• Sleeve Design
– Attachment / Hinge
– Fragment Size and Material
– Internal Scoring
– Adhesive
– Missile Integration
• Adapt Shipping Container to Accommodate Missile Sleeve

Flight Test Results
• No Launch Rail Interference
• Aerodynamics Proven
• Flight Stability Proven
• Hit Accuracy Not Compromised
Mod-K Conclusions
• Significant Increase in Number of Lethal Fragments
• Provides Capability Against Personnel and Light Vehicle Targets
• Sleeve Design Has Minimal Effect on RHA Penetration
• Fragment Sleeve Expands the Role of HF Missile for Targets of Opportunity

TECHNICAL APPROACH
Semi-Active Laser (SAL) Lock On After Launch (LOAL)Engagement of individual targets with high probability of single shot hit requires terminal or command to line-of-sight
guidance. Low signature targets embedded in complex, cluttered environments can only be reliably engaged through visual
acquisition & operator designation.
