USS Kittiwake was a submarine support and rescue ship, in service from 1946 through 1994. In 1986, it recovered the black box from shuttle Challenger disaster. It was decommissioned in 1994. In 2009, US Navy sold USS Kittiwake to Cayman Islands for $1. The group of dive shops then chimed in and arranged to strip the ship of all items that could be dangerous to the Cayman Reef system. USS Kittiwake was finally sunk off Seven Mile Beach, Grand Cayman on 5 January 2011.
Kittiwake is a wreck dive although it was sunk on purpose, not accidentally. The deepest point, near the propelling screws is at 20 meters, the top of the bow is at 6 meters. All in all, it is a pretty deep dive, especially for young divers like Anna. It was her deepest dive to date!
