The DoD US Navy NAVSEA NSWC Carderock has operated the William B Morgan Large Cavitation Channel (LCC) since 1991. The LCC is one of the world's largest and most technically advanced high speed, variable-pressure closed-loop water tunnel facilities. This facility is designed for a wide variety of hydrodynamic and hydro-acoustic tests. Its overall size and capabilities allow test model Reynolds numbers to approach, or even achieve, those of full-scale air or water-borne transportation systems.
