The Disruptive Deep Fluting (DDF) is an external barrel structure designed to significantly reduce primary (blast compression and expansion) and secondary (sinusoidal resonance) wave events in barrels, improving accuracy, reducing heat, and extending barrel life. Using data from the 2024 TACOM HO Finite Element Analysis (FEA) study. Noveske’s Combat Systems Development & Support program launched an R&D project. The goal was to determine the optimal surface area per linear inch to effectively disrupt these wave events while maintaining the lightweight barrel contour already used by U.S. Special Operations personnel.
