USNS Indomitable (T-AGOS-7)

USNS Indomitable (T-AGOS-7) was a United States Navy Stalwart class ocean surveillance ship in service from 1985 to 2002.

History
Indomitable was laid down by the Tacoma Boatbuilding Company at Tacoma, Washington on 26 January 1985 and launched on 16 July 1985. She was delivered to the U.S. Navy on 26 November 1985. She was placed in non-commissioned service in the U.S. Navy's Military Sealift Command as a United States Naval Ship with a mixed Navy and civilian crew on 1 December 1985.

Stalwart-class ships were originally designed to collect underwater acoustical data in support of Cold War anti-submarine warfare operations in the 1980s. Accordingly, Indomitable employed Surveillance Towed Array Sensor System (SURTASS) equipment on Cold War underwater surveillance duties.

After the end of the Cold War in 1991, requirements for such surveillance declined. By 1998, Indomitable's SURTASS gear had been removed, and she had received an AN/SPS-49 radar for use in counternarcotics surveillance.

Indomitable was retired from service on 2 December 2002 and stricken from the Naval Vessel Register the same day. On 9 December 2002, she was transferred to the National Oceanic and Atmospheric Administration (NOAA).

Later career
NOAA converted Indomitable into an oceanographic research ship. Renamed NOAAS McArthur II (R 330), she entered service in the NOAA fleet in May 2003. McArthur II is an active member of the NOAA Pacific Fleet.
