USS Spiegel Grove: From Cold War Warship to Key Largo’s Diving Crown Jewel

A Warship’s Transformation: From the Cold War to Coral Reef

The USS Spiegel Grove (LSD-32), a Thomaston-class dock landing ship, stands as a remarkable example of transformation. Commissioned on June 8, 1956, this vessel bore witness to the tensions of the Cold War, serving with the 6th Fleet and even playing a role in the recovery efforts of the Apollo 14 mission. Decommissioned on October 2, 1989, and struck from the Navy list on December 13th of the same year, the Spiegel Grove began a new chapter in its life, destined for the waters off Key Largo, Florida, as an artificial reef.

The Dramatic Sinking and Unintentional Acrobatics

The Spiegel Grove‘s transition to artificial reef in May 2002 didn’t exactly go as planned. After being relocated from the James River “mothball fleet” in Newport News, Virginia, the ship sank prematurely, landing upside down the day before its scheduled sinking, with its bow defiantly jutting out of the water. This unexpected turn of events likely captured international attention. However, through a combination of ocean currents, surge, and a fortuitous dip in the seabed, the Spiegel Grove partially righted itself. Salvage crews later completed the job, finally settling the vessel in its intended upright position. This dramatic sinking, while unplanned, perhaps foreshadowed the ship’s resilience and its future as a vibrant, thriving reef.

Exploring the Depths: A Diver’s Paradise

Today, the Spiegel Grove rests approximately six miles off Key Largo at Dixie Shoal (25°04′N 80°24′W) within the Florida Keys National Marine Sanctuary, transformed into a world-renowned dive site. Accessible by chartered boat from Key Largo, the wreck offers a unique experience for divers of all skill levels. The main deck sits at a relatively shallow depth of around 60-65 feet, making it ideal for beginners. However, the seabed surrounding the wreck plunges to approximately 130 feet, providing a more challenging dive for experienced technical divers with proper training and certification for penetration dives.

Seven mooring balls mark various entry points to the wreck, each offering distinct dive routes. The amidships moorings are generally recommended for those seeking shallower explorations with maximum visual impact. Divers can expect to encounter an abundance of marine life, including Goliath groupers, sharks, colorful reef fish, and a vibrant tapestry of corals and sponges clinging to the ship’s structure.

While the Duane and Bibb offer exciting dives for more experienced divers, the Spiegel Grove, with its varying depths, caters to a broader range of experience levels. The Benwood provides a good starting point for newer divers.

An Ecological Oasis: The Ship’s Second Life

The Spiegel Grove‘s story doesn’t end with its military service or even its dramatic sinking. It continues as a vital part of the local ecosystem. The ship’s massive structure provides a complex habitat for a wide array of marine species. Fish populations thrive, finding shelter and food within the wreck. Corals and sponges encrust the metal surfaces, creating a living tapestry. While research is ongoing, some experts suggest that artificial reefs like the Spiegel Grove may contribute to increased fish populations and improved ocean health.

A Legacy Beneath the Waves

The Spiegel Grove offers a compelling narrative of transformation. From a Cold War warship to an underwater haven teeming with life, it continues to fascinate and inspire. Its presence on Dixie Shoal isn’t just a spectacle for divers; it’s a testament to the ship’s enduring legacy, both above and below the waves.

These, too, tell stories of human endeavor and the power of nature.
