The Littoral Combat Ship (LCS) concept boat was studied for the U.S. Navy.  The LCS is intended to operate in coastal areas of the globe, and the ship will be fast, highly maneuverable, and geared to support mine detection/elimination, anti-submarine warfare, and surface warfare, particularly against small surface craft.

Alden performed a 1:5 scale physical model study for the air intake and the uptake for one of the 2 gas turbine enclosures.  The main objectives of the model study were to provide velocity distributions and pressure loss data within the intake, uptake, and enclosure as well as the mixing of the enclosure cooling air with the turbine exhaust gas and the exhaust plume flow characteristics.
