A Naval Airship is a type of lighter-than-air craft used by navies for reconnaissance, surveillance, and anti-submarine warfare. These airships are typically filled with helium or hydrogen, allowing them to float and maneuver in the sky. They can carry various sensors and equipment, making them valuable for monitoring large areas of ocean and coastline. Historically, Naval Airships played a significant role during World War I and World War II, providing a strategic advantage in maritime operations. Their ability to remain airborne for extended periods allowed for continuous observation and intelligence gathering, contributing to naval tactics and safety.
