NAS blimp bases. NAS blimp bases, (Navy Air Stations Blimps bases), were United States Navy blimp bases built to protect coastal waters during World War II. Navy Blimps could stay in the air and patrol coastal waters much longer than airplanes. The bases were also called Naval Lighter-than-Air Bases.  The blimps (non-rigid airships) were built by Goodyear Aircraft Company of Akron, Ohio. The blimps were powered by two aircraft radial air-cooled engines, the crew worked and on long patrols lived in a car under the envelope. The Navy's anti-submarine warfare operation operated in both the Atlantic and Pacific Ocean. To protect the blimps from strong winds and thunderstorms on the ground most bases had one or more larger airship hangars. Due to the shortage of steel during the war, many hangars were built out of wood.

The start of World War II blimps use bgan on September 23, 1935, when the US Navy purchased the airship Defender from Goodyear. Defender was Goodyear's largest advertising and passenger airships. Defender was delivered to NAS Lakehurst on October 5, 1935. Defender was used for crew training and give the Navy designation G-1, the first G-class blimp. Defender was lost in a midair collision with the smaller L-2 on June 8, 1942, during a night flight. Seven G-class blimps were built. The L-class blimp were smaller blimps use mostly for training, with 10 built. Five L-class blimp were civil blimps of Goodyear fleet: Resolute, Enterprise, Reliance, Rainbow, and Ranger. M-class blimps was the largest anti-submarine warfare blimp, four were built for use in Latin America bases. In addition to anti-submarine warfare, the blimps did assist with Search and rescue missions. US Navy blimps did over 37,000 patrols during World War II. Long patrols could be up to 26 hours in the air. The K-class blimp had a crew of 10 and had radar and  Magnetic anomaly detector for sub hunting. Not used often but each blimp had up to four depth charges, naval mines or acoustic torpedoes and a .50-caliber machine gun
 Post World War II:
The N-class blimp was not retired till 1962, with 18 built.  The M-class blimp was retired in 1956.
