The USS Kittiwake (ASR-13) was a 251 foot (76.5 m) long, US Navy Chanticleer class submarine rescue and salvage vessel built in 1945. The vessel was named after the species of gull Kittiwake, named for its shrill cry 'kittee-wa-aaake, kittee-wa-aaake.' It had a long and illustrious career culminating with the recovery, in 1986, of a section of the solid rocket booster from the US NASA' Space Shuttle Challenger disaster. It is commonly reported that the Kittiwake recovered the black box, or flight data recorder, but this could not be because the Challenger had no such device. After decommissioning in 1994 the Kittiwake was placed in the MARAD James River Group Reserve Fleet. On February 10, 2010 it was towed to Dominion Marine in Norfolk, VA where it was cleaned of toxic materials. The ship was then towed to the Cayman Islands. On 05 January 2011 it was deliberately scuttled at the northern end of Seven Mile Beach to serve as an artificial reef. On October 6, 2017 wave action from passing Tropical Storm Nate moved the wreck towards a nearby natural reef, where it fell on its port side. More information about the vessel's history can be found at USS Kittiwake. Incidentally, the name Kittiwake lives on as the US Coast Guard cutter Kittiwake (WPB 87316).
There are five open decks that can be explored, including the two decompression chambers. The following YouTube video from Whalen Productions is definitely worth watching.
And, a short YouTube video of the sinking of the Kittiwake.
