Vasco Nuñez De Balboa Naval Base

The Naval Base Panama Canal Zone was a series of United States Navy bases used during World War II to protect the Panama Canal and surrounding shipping lanes. The main base was Naval Station Coco Solo, which had been in operation since 1918, and was supported by a number of other bases and defenses, including anti-torpedo nets, naval mines, and anti-aircraft guns. The Canal Zone was a vital strategic location, and the US increased its defenses in response to the threat of Axis powers, including Japan's plan to bomb the Canal in 1943.learn more on wikipedia
