USS Juneau (CL-52) was a United States Navy Atlanta-class light cruiser torpedoed and sunk at the Naval Battle of Guadalcanal on 13 November 1942. In total, 687 officers and sailors, including the five Sullivan brothers, were killed in action as a result of her sinking. Only 10 survivors were rescued after eight days in the water. To honor the five Sullivan brothers and Juneau, the U.S. Navy has since commissioned two ships named USS The Sullivans and two ships named USS Juneau. On 17 March 2018, Paul Allen's research crew on board RV Petrel located the wreck of Juneau at a depth of about 4,200 m (13,800 ft) off the Solomon Islands.

RV Petrel, or R/V Petrel, is a 76.45 m (250.8 ft) research vessel sailing under the UK flag and owned by the United States Navy and once owned by Microsoft co-founder Paul Allen. The ship is named after the petrel, a sea bird. The ship was completed by Brattvaag Skipsverft, Norway in 2003 as the deepwater offshore inspection vessel Seaway Petrel for service with Stolt Offshore. She was later renamed Acergy Petrel, then Seven Petrel with Subsea 7.
