Advanced Counter-RPG Projectiles For Multigun Defense Systems Navy SBIR FY2004.2 - Quick Response Topics Sol No.: Navy SBIR FY2004.2 Topic No.: N04-902 Topic Title: Advanced Counter-RPG Projectiles For Multigun Defense Systems Proposal No.: N042-902-0430 Firm: Nomadics, Inc. 1024 S. Innovation Way Stillwater, Oklahoma 74074-1508 Contact: Marcus Grone Phone: (405) 372-9535 Web Site: www.nomadics.com Abstract: Under funding from DARPA, Nomadics has demonstrated the potential for deploying multi-gun fixtures as a means of defeating rocket-propelled grenades (RPGs). These early tests have created a database that will be invaluable in advancing the work toward optimization of the initial concept through enhancements in both the gun fixture and the projectiles as well as in the defeat strategies based on this approach. Under the currently proposed work, we will focus on optimization of the projectiles. By designing novel projectiles one can increase the probability of disrupting the warhead of an RPG or destroy the fuzing system such that the warhead does not high order. During Phase I, optimization enhancements will be demonstrated to show that these early prototypes should be further refined in Phase II. Nomadics' initial work in this area as well as the company's rapid prototyping efforts will help to ensure that the envisioned system moves quickly toward acquisition and deployment to meet this urgent need. Benefits: Disrupting the warhead or effectively defusing RPGs will defeat the device, reducing the attack to a simple kinetic one. While a 2.5 kg projectile at up to 300 m/s is a sizeable kinetic projectile, it can be defeated by the armor of Stryker and Bradley vehicles as well as other vehicles with add-on armor packs. Packs designed to try to defeat the shaped charge itself would be infeasible. Due to terrorist threats, the system will find crossover application for homeland security and protection of nonmilitary deployed assets, such as embassies. Integrated as part of a sensing and response system, the technology in less lethal configurations will find application in civilian security scenarios. Return
