IS4S is a growing small business with experience in all of the fundamental research disciplines required to support ordnance technology development. These disciplines include structural mechanics, material science, explosives/energetic materials, and advanced weapon development. IS4S employees have engaged in R&D activities for AFRL, DTRA, DARPA, and other agencies of the DoD, for many years on ordnance development programs. IS4S is currently the prime contractor on AFRLs Enhanced Lethality Ordnance and Modeling (ELOM) contract. This contract has efforts underway conducting R&D on technologies focused on high-speed-strike weapons, close-combat-support weapons, selectable-effects weapons, agent-defeat weapons (addressing targets containing chem and bio agents), as well as related modeling and simulation. These projects include both fundamental investigations, such as experimental characterization and modeling of blast propagation in structures, to weapon development activities, such as conducting arena tests and participating in live drop tests of prototype warhead concepts. IS4S was just recently awarded the Agile Acquisition IDIQ Contract by the Air Force Life Cycle Management Center. The IS4S staff is a diverse mix of scientists and engineers, most with advanced degrees, who are committed to helping DoD customers develop solutions to some of the militarys most complex challenges.
