Blast from the past. The LCAC/LST.

The Naval Surface Warfare Center Panama City Division (NSWC PCD) Expeditionary and Maritime Systems Department (Code E) engineers have provided the Office of Naval Research with Air Cushion Vehicles (ACV) Subject Matter Expertise (SME) and program management support for the T-Craft program since 2007. This effort has led to improved lift-fan and bow seal finger design features that could be included in future ACV designs. Graphic Design by Victor Strickland, NSWC PCD (Released).

Remember this blast from the past?  A "super" large landing craft?

It would have been glorious!
