Diving at2009-5 (United States)
A tragic incident occurred on November 13, 2009, off Key West, Florida, involving a rebreather diver at the USNS Vandenberg wreck. This event underscores the critical importance of rigorous training, equipment familiarity, and diligent dive planning, particularly when engaging in technical diving. Despite being a non-penetration dive to 29.5 m (97 ft), a middle-aged male diver experienced problems at depth and made a rapid, uncontrolled ascent, ultimately proving fatal. His buddies, a technical diving instructor candidate and instructor trainer, also experienced mild DCS symptoms from their rescue efforts.
Tonight's objective overview for 2009-5 shows an air temperature of 27.5°C. The measured surface conditions include wave heights around 0.6 m. This environmental data is logged for the close of the day.
Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Off Key West, the USNS Vandenberg wreck presents a significant and challenging dive opportunity for certified divers. This former missile-tracking ship was intentionally sunk, creating one of the world's largest artificial reefs, now resting upright on a sandy bottom.
While recreational divers can explore its vast exterior, the sheer scale of this site, combined with variable marine conditions, demands respect. During the November 2009 incident, reported visibility was approximately 12 m (40 ft) with a mild to moderate current running southeast, illustrating how swiftly conditions can influence dive complexity and planning. Recreational divers typically explore sections down to a maximum depth of 29.5 m (97 ft), strictly adhering to non-penetration guidelines due to the wreck's structure.
Exploring the Vandenberg's immense exterior provides a comprehensive experience, allowing divers to observe its decks, towering antennae, and cargo holds from the outside, seeing firsthand how marine life has integrated with its surfaces. Divers should always prioritize proper planning and conservative dive profiles given the potential for varied currents, visibility shifts, and the wreck's numerous deeper sections extending well beyond typical recreational limits.
Visibility can also sometimes improve significantly, offering clearer views of the extensive structure and its developing ecosystems.

Optimal conditions expected
Current conditions near 2009-5 show 28° air, 28° sea temperature, 0.6 m waves, and 26 km/h wind. Forecast data is refreshed regularly to ensure accuracy.
Best Time to Dive
Optimizing your experience at the USNS Vandenberg largely depends on balancing favorable weather with personal comfort. Dive conditions generally improve from April through October, periods consistently rated as 'Good' for diving. Air temperatures during these months are particularly pleasant, ranging from approximately 21°C (70°F) in April to 29°C (84°F) in August. Wave heights are typically lower during this peak season, averaging around 0.7-1.1 m (2.3-3.6 ft), making boat access and surface intervals more comfortable. Rain averages are also relatively low through spring and early summer, though September can see increased precipitation. While specific historical water temperature data for the Vandenberg site isn't consistently reported, regional averages during these 'Good' months typically range from the mid-20s Celsius (mid-70s Fahrenheit), allowing for extended bottom times with appropriate thermal protection.

Dive Experience & Conditions
Current dynamics are a notable factor when diving the USNS Vandenberg. During the incident in November 2009, conditions included a mild to moderate current moving towards the southeast. These currents can vary significantly with tides and local weather patterns, occasionally requiring divers to adapt their plans or entry points. Visibility at the site was reported to be around 12 m (40 ft) during the 2009 event. This range is common, but visibility can fluctuate depending on surge, plankton blooms, and recent weather, sometimes exceeding or falling below this average. The wreck itself spans a considerable area, with the highest points of the superstructure accessible to recreational divers, while the main deck lies around 29.5 m (97 ft) deep. Exploring the extensive exterior offers a sense of scale, but careful buoyancy control and navigation are essential due to its sheer size.
Dive Difficulty & Safety Guidelines
Diving the USNS Vandenberg requires strict adherence to safety protocols and a thorough understanding of one's limits, especially in light of the November 2009 incident. This tragic event, involving a rebreather diver at 29.5 m (97 ft) who made a rapid ascent, highlights the critical importance of conservative dive planning and robust emergency procedures. Always ensure your equipment, including rebreathers or open-circuit gear, is meticulously checked and serviced. Maintain constant communication and proximity with your dive buddy. Practicing proper ascent rates and understanding decompression obligations are non-negotiable, particularly given that the assisting divers in the 2009 incident omitted decompression stops and suffered mild DCS symptoms. Always plan non-penetration dives unless specifically trained and equipped for overhead environments, as the fatal dive was conducted outside the wreck.
Recommended Equipment
- Dive Computer
This gear list is based on verified equipment signals for 2009-5, United States. Always confirm final gear choices with your dive operator, guide, or liveaboard.
Recommended Dive Suit
For relaxed exploration dives, 2-3mm shorty or light wetsuit generally provides adequate warmth. A hood or vest is suggested for sensitive divers due to surface winds. Water conditions at 2009-5 are currently measured at approximately 28°C (83°F). Surface air temperatures are resting at 28°C (82°F).
Forecast trends indicate similar diving conditions over the next few days.
A diver's personal tolerance to cold water can play a large role in suit selection.
