The Combat Tactical Vehicle Technology Demonstrator (CTV-TD) undergoes tests at the Sand Mountain Recreation Center located outside Fallon, Nev. Built under contract for the Office of Naval Research (ONR) at the Nevada Automotive test Center (NATC), the CTV-TD is a testbed for the Joint Light Tactical Vehicle (JLTV) family of vehicles. The CTV-TD offers several advantages and new technologies, including adjustable ride height, central tire inflation system, an integral rollover protection system (ROPS) and improved survivability over the current High Mobility Multipurpose Wheeled Vehicle (HMMWV).
