Construction

Atlantis was built by Halter Marine Inc., Gulfport, Mississippi.[3] She was laid down in August 1994 and launched in February 1996.[4] She was delivered to the U.S. Navy on 25 February 1998, as R/V Atlantis (AGOR-25) a Thomas G. Thompson-class oceanographic research ship.

The R/V Atlantis docked in Gulfport, Mississippi on a foggy winter day in 2020.

Atlantis is scheduled for midlife maintenance and refitting starting in 2020, with an expected release in 2021.[5]
