DAHLGREN, Va. – The spin rate and velocity of a projectile shot from a five-inch gun are so fast only a camera capturing 75,000 frames per second can freeze it mid-flight. At this speed, unseen phenomena become visible, revealing critical data that underpins the precision and impact of modern weapon systems. At the Naval Surface Warfare Center Dahlgren Division (NSWCDD), these specialized cameras are essential for analyzing hypersonic projectiles and monitoring explosive dispersals. High-speed imaging transforms how we test, refine, and deploy advanced military systems, ultimately safeguarding lives and empowering the Navy with precision and lethality.
