Function: The USNS Stalwart (TAGOS 1), USNS Indomitable (TAGOS 7) and USNS Capable (TAGOS 16) are monohull ocean surveillance ships originally designed to gather underwater acoustical data.





History: Stalwart, along with two sister ships, was deactivated in the early 1990s when the end of the Cold War signaled a reduced submarine threat from the former Soviet Union, however, the Atlantic commander decided to convert the three ships for a new mission ? finding narcotics traffickers. They now support the Joint Interagency Task Force, East. The three Stalwart class ships have been modified for a drug interdiction mission. The underwater acoustic array was removed, and an air search radar, integrated display system, sophisticated communications suite and other special mission equipment were installed to detect and monitor suspected drug traffickers.
