USNS Vandenberg

The Vandenberg tracked missiles and spacecraft through the Cold War, her giant parabolic radar dishes following launches downrange from Cape Canaveral. Scuttled south of Key West in 2009 as one of the largest artificial reefs ever created, she sits upright with those dishes still mounted - the most surreal photographic subject in the Keys, a satellite ship parked on the seabed. Structure starts around 14-20 m and the tour deepens from there, past kingposts, cranes, and swim-through passages prepped for trained divers. Barracuda and jacks own the superstructure, goliath groupers boom in the interior, and lionfish hunters work her constantly. Two dives minimum; she rewards ten.

Nitrox: Đáng dùng ở đây — các hồ sơ nằm trong khoảng độ sâu mà nitrox có thể kéo dài thời gian không dừng một cách thực sự có ý nghĩa (khi đã được đào tạo sử dụng).
