The U.S. Navy has at least tested small hydrofoil boat based on the VT Halter Marine Mk Mod 2 High Speed Assault Craft, a predecessor to the service's stealthy Combatant Craft Assault special operations watercraft, or CCA. The revelation comes more than 25 years after the service retired its six Pegasus-class missile boats, the last of its operational hydrofoils.
The existence of the hydrofoil design first emerged in a video that the Naval Surface Warfare Center, Carderock Division, or NSWC Carderock, posted on YouTube on Mar. 12, 2019. A clip showing the small boat moving at high speed is part of a larger montage of clips of the center's work attached to the Navy's “Forged by the Sea” recruitment commercial.
