Tonight, a remotely-operated vehicle (ROV) will shoot video 18,000 feet under the sea to take viewers on a live-streaming tour of the recently discovered USS Indianapolis.

Indianapolis sunk in the final days of World War II when it was hit by two Japanese torpedoes after delivering components of the “Little Boy” bomb dropped on Hiroshima.

The sunken battleship was discovered Aug. 18, 2017 by an expedition team led by Microsoft co-founder Paul Allen, using a research ship equipped with state-of-the-art subsea technology.

The research vessel RV Petrel is equipped with two subsea vehicles (an AUV and ROV), side scan sonar, interferometric bathymetry, HD cameras, LED lights and underwater positioning and navigation systems.

RV Petrel crews will take viewers on a live tour of the ruins which have been resting at the bottom of the North Pacific Ocean for 72 years.

Watch the live-stream on PBS.org, the PBS Facebook page, or PaulAllen.com at 10 p.m. EST or 7 p.m. PT.
