Split-second science: Dahlgren Division engineers capture first live data on projectile and shockwave interaction

DAHLGREN, Va. – Naval Surface Warfare Center Dahlgren Division scientists and engineers used a M110 Howitzer modified with a 155 mm barrel to launch projectiles traveling nearly four times the speed of sound toward controlled blasts of 30 to 100 pounds of dynamite. The groundbreaking test was used to study how shockwaves affect high-speed rounds. (NSWCDD Photo) By Kristin Davis, NSWCDD Corporate Communications, Nov. 21, 2025  DAHLGREN, Va.  –  N…

Naval Surface Warfare Center captures first live data on projectile and shockwave interaction in tests

“We took a high-speed projectile and did what Dahlgren does best — we shot it from a gun,” said Lyn Thomas, Distinguished Scientist for Surface Engagement Systems (Acting) at NSWCDD. “The new part was studying what happens when the projectile meets a blast wave mid-flight.” The test aimed to gather data that will improve computer models simulating missile and blast behaviour. Coordinating projectile flight and explosive detonation required preci…
