Multi-Mission Railgun
Warfighting Payoff • Responsive, Wide Area Coverage • Precision fires via guided munitions • Deep magazines – cost effective • Enhanced safety with Low Collateral Damage • Multi-mission, Multi-Barrel Hyper Velocity Projectile (HVP)
HVP & Gun Systems equates to Distance • 20 MJ Railgun → 50 nautical miles • 32 MJ Railgun → 110 nautical miles
Railgun Development Focus • Technology Proven at 32MJ Muzzle Energy Focus shifting to rep rate operations Tactical Barrel & Mount Compatibility
• Rep Rate 32MJ Launcher & Test Stand Establish Manufacturing with BAE Systems Validate Bore Life during Rep Rate Ops
• Rep Rate 32MJ Gun Mount (100NM capable) Leverage Navy Gun Mount Experience Integrate HVP Handling & Initialization Design for Pulsed Power Transfer & Cabling

Advanced Energy Systems
System / Ship Integration
High Density Power Electronics Pulsed Forming Network
• Charging Power Supplies for Advanced Energy Systems • Converting Ship’s Power to High Voltage for Electric Weapons • Supports Electric Drive, Railguns, Lasers & Radars
Battery Energy Storage
• Capacitor based PFN • Higher Energy Density lowers shipboard volume/footprint • Rep rate operation & thermal management
• Dynamic power sharing across platform • Designing with Space and Weight Constraints • Assessing Thermal and EM Field management
Actively Cooled Rep-Rate Pulsed Power Module
Pulsed Power in ISO Container for Mobility & Demo Platform Flexibility
• Energy Storage to buffer Prime Generators • Ready Reserve Energy for response to “quick” threats • Requires close Ship Safety Design, Test & Monitoring

UNCLASSIFIED – DISTRIBUTION A
AT-Sea Testing Update
• The U.S. Navy will fire it’s first-ever Railgun at sea on the Eglin Air Force Base Maritime Test Range in late Summer of 2016 aboard JHSV5, USNS TRENTON
• The test will fire a GPS-Guided Hypervelocity Projectile from a Railgun at a fixed over-the-horizon target
• Further, it will validate system performance models for a dynamic Railguns

Not a New Concept
• Louis Octave Fauchon-Villeplee submitted first patent for a Railgun on 1 April 1919 for an “Electric Apparatus for Propelling Projectiles” – Patent no. 1,421,435 issued 4 July 1922
• UK, Russia, China and U.S. Army (among others) have been working on Railguns for decades – Current U.S. Navy program began in earnest in 2005
