The VSTOL Support Ship (VSS) was a proposed light aircraft carrier design for the United States Navy in the late 1970s that would be smaller and less expensive than the Navy`s existing aircraft carriers such as the Nimitz-class. The design would cost one-quarter as much, although the V/STOL aircraft it would carry would have reduced performance. The United States Senate and others supported the design, but it was ultimately rejected by the Navy.
