USS Vandenberg

The USS Vandenberg is a deliberately scuttled 524-foot former U.S. military ship (USNS General Hoyt S. Vandenberg) that rests upright on a sandy bottom seven miles south of Key West. The wreck provides broad, multi-level exploration with large open bridge, hangar bays, decks and exposed features such as radar platforms and railings; numerous large cut-outs allow horizontal swim-throughs and panoramic views through intact corridors. It is widely regarded as one of Key West’s most popular and iconic dive sites. The site is boat-access only, with dive boats deploying a mooring line and divers entering from the surface above the wreck. Depths range from just under 50 ft at the topmost decks down to about 145 ft at the hull, with the main deck near 100 ft. Water temperatures average around 80°F and visibility on calm days is generally good, often in the tens of feet. Open-ocean currents can be moderate to strong, so dives are commonly scheduled for morning or slack tide; because of depth and possible currents divers must carefully manage gas and bottom time. Advanced Open Water or equivalent deep certification is recommended for full-depth exploration, though Open Water-certified divers may be allowed to visit the shallower superstructure (around 45–50 ft) under professional guidance. Penetration of tight interior spaces is generally avoided for safety. The vessel was intentionally sunk in May 2009 to create an artificial reef; its large scale and intact features make it notable for both historical interest and recreational wreck diving.
