The U.S. Navy's airship program began in the early 20th century, focusing on the development and use of lighter-than-air craft for reconnaissance and patrol missions. Airships, such as the USS Akron and USS Macon, were designed to carry out surveillance over vast ocean areas, providing valuable intelligence during both World Wars. Despite their initial promise, airships faced challenges, including vulnerability to weather and enemy attacks. The program gradually declined after World War II, as advancements in airplane technology offered more effective and safer alternatives for military operations. Today, airships are primarily used for research, advertising, and surveillance purposes.
