  Objective:  Develop and evaluate candidate novel materials for small and medium caliber projectiles that demonstrate increased target damage, improved lethality, and enhanced battle damage indicators.
  Description:  The current small and medium caliber weapon systems utilize projectiles that rely strictly on kinetic energy to provide damage to the target. The ability to couple that kinetic energy with a material that provides a significant chemical energy release (such as a reactive material) is desirable for increased weapon performance in addition to the potential for enhanced battle damage indicators. There are several challenges associated with this tasking such as: material strength, material density, and energy release over the velocity range of 2500 ft/s - 3500 ft/s. Research and development is required to develop novel materials and innovative processes to achieve the mechanical properties (of the projectile) necessary to survive launch, penetrate the target, and deliver the chemical energy in a way that improves the lethality of the round.

  PHASE I: Conduct research and development pertaining to the investigation of the structural, mechanical, and chemical properties of candidate novel materials. Begin modeling effort to characterize material survivability during gun launch, material break up, and energy release on target impact.
  PHASE II: Generate scaled samples of materials identified in Phase I to evaluate and measure the chemical energy output and the ability of the candidate materials to withstand gun launch. Perform ballistic and target impact analysis of candidate solutions. Update launch and impact model to reflect test data. Perform an assessment of each materials ability to increase battle damage indicators over status quo.

  PHASE III: Build full scale assets from the most promising candidate solutions. Provide samples for further testing at a Navy facility. Test launch survivability, ballistics, target damage and BDI compared to existing assets. Transition will be contingent upon the choice of the most appropriate caliber(s) for technology transition. The contractor will work with the applicable Navy Program Office in qualifying new projectile configurations. Qualification will include Manufacturing Readiness Level (MRL) assessments, test firings, and Insensitive Munitions (IM) assessments and/or testing, as required. Any impact to IM will be coordinated with the PEO IWS IM Coordinator. This technology could potentially be applied to large caliber weapons but will require investigation of the impact of a scaled up approach from the small/med caliber size to larger projectiles. An analysis will need to be conducted that address performance of larger projectiles, cost of larger masses of the novel materials, and the costs to scale the manufacturing processes.
