USNS Huntsville (T-AGM-7) was a Watertown-class missile range instrumentation ship acquired by the U.S. Navy in 1960 and converted from the SS Knox Victory Victory ship cargo configuration to a missile tracking ship, a role she retained for a number of years before being struck from the Navy List in 1974.

A tracking ship, also called a missile range instrumentation ship or range ship, is a ship equipped with antennas and electronics to support the launching and tracking of missiles and rockets. Since many missile ranges launch over ocean areas for safety reasons, range ships are used to extend the range of shore-based tracking facilities.
