SUBMARINE BASE, COCO SOLO, CANAL ZONE.
The submarine base at Coco Solo was established 6 May 1918. The site corresponds with modern-day Cativá in Panama. It was on the Atlantic Ocean (northwest) side of the Panama Canal Zone, near Colón, Panama. Five C-class submarines were based there during 1914–1919.
On 7 December 1941, three V-Class submarines (Barracuda, Bass and Bonita) were stationed at Coco Solo. During World War II, Coco Solo also served as a Naval Aviation Facility, housing a squadron of P-38 Lightning aircraft.
By the 1960s, no U.S. Navy vessels remained, only some support staff and housing. After the turnover of the Panama Canal to Panamanians in 1999, US military activity ceased at Coco Solo.
