The U. S. Navy’s first airship was the DN-1 which first flew in April 1917. The Navy flew dirigibles out of McCalla Field, Cuba which was operational from 1931-1970. I am not certain of the perspective because I can’t determine if photographer meant to depict his own entrance to the bay or the dirigible’s entrance. Judging by the ships visible in the distance, I can see at least four, the photographer could be northwest of the airfield.
This photograph was purchased from a Baltimore antique shop in November 2020.
