USNS Chauvenet (T-AGS-29) was a multi-function (littoral, coastal and deep ocean) survey ship laid down on 24 May 1967, at Upper Clyde Shipbuilding Corp., Glasgow, Scotland.

The ship conducted coastal hydrographic and topographic surveys under the technical direction of the Oceanographer of the Navy through the U.S.

Chauvenet was the first Navy vessel specifically designed and built to conduct coastal hydrographic surveys.

The launches themselves were 36 foot fiber glass, diesel powered, "sports sedans" capable of 30 kn (35 mph; 56 km/h) smooth water speed and modified for survey operation.

[11][12] Chauvenet grounded two hours before midnight 8 May 1982 on Dauisan Reef (09°47′0″N 121°13′30″W / 9.78333°N 121.22500°W / 9.78333; -121.22500) in the Sulu Sea while transiting from Subic Bay to survey areas in Indonesia.

In 1999 the cruise visited the ports of the Canary Islands and Lisbon, Portugal, Cork, Ireland and Le Havre, France.

On 26 July 2005 the ship entered the agency's Beaumont Reserve Fleet but was reactivated 7 October for Hurricane Rita relief at Lake Charles, Louisiana.

During 2006 the ship was converted with the name changed to Pacific Collector for use by the DOD Missile Defense Agency.

Along with Pacific Tracker the ship is one of the agency's sea based platforms collecting and recording critical test data.
