What is The Full History of This Wreck

Early Years

Construction and Purpose: The San Pablo was built in 1915 in Belfast, Ireland, as a refrigerated cargo ship. It was primarily used to transport bananas and other tropical fruits between Caribbean ports and the United States, operating under various shipping companies, including Balboa Shipping Co. by 1931.

World War II and Sinking

Target of German U-Boats: With the onset of World War II, the San Pablo became vulnerable to attacks from German submarines. In May 1942, while near the Yucatán Channel, it was fired upon by a U-boat. The crew managed to evade capture and reached safety in Puerto Limon, Costa Rica.
Final Attack and Sinking: While docked in Costa Rica, the San Pablo was struck by two torpedoes, which caused it to flood rapidly and sink, resulting in the loss of all 24 crew members aboard. The wreckage left only the superstructure and masts above water.

Recovery and Military Use

Refloating and Repairs: In March 1943, the San Pablo was raised and towed to Tampa, Florida, for repairs. However, the War Shipping Administration deemed it a total loss. In December 1943, it was relocated to Panama City, where it was slated for a top-secret military operation.
Project Campbell: The ship was repurposed as part of Project Campbell, a secret operation by the Office of Strategic Services (OSS), the precursor to the CIA. The project aimed to test a remote-controlled explosive-laden speedboat designed to target enemy vessels without risking human lives. The San Pablo was chosen as the target for this experiment.

The Destruction of the San Pablo

The Test: On August 11, 1944, the San Pablo was destroyed in a controlled explosion. A remote-controlled speedboat, disguised as a civilian fishing vessel, was loaded with over 3,000 pounds of explosives. The operation was successful, with the ship sinking within two minutes of the detonation.
