Navy battleship strategy in the 1920s and 30s envisioned 10 large dirigibles stationed in Hawaii to provide strategic recon in advance of the fleet. Five dirigibles at a time, equipped with five F9C-2 Sparrowhawk "parasitic" fighters could form a moving recon line over 1000 miles wide, advancing at 80 knots... five times the speed of a light cruiser screen. The dirigibles had a flight duration capability of over 9000 miles. By the mid 1930's,the Sparrowhawks were equipped with both keyed & voice radio communications as well as radio homing back to the carrier ship. With two .30 caliber machine guns firing through the propeller and a 50-75 knot speed advantage over float planes of the period, the F9C-2 was capable of taking care of itself.
USS Akron and USS Macon were the first two (and only) purpose built lighter than air aircraft carriers. Both were lost at sea, Akron crashed into the Atlantic on 04 April 1933, taking 72 crewman down with her, including RADM William Moffett, Chief of the Navy Bureau of Aeronautics. There were only three survivors. The general practice was for the airship to takeoff without her aircraft, and then embark them later on the "trapeze". Fog grounded the Akron's aircraft on the day of departure (April 3) and all aircraft and pilots survived.
As DDP59 mentions, USS Macon, crashed into the Pacific, two years later. Macon had just completed fleet excercises and was returning to Naval Air Station Sunnyvale, when high winds damaged her aft dorsal fin (due to a known design defect that was due for correction) and she was set down into the water off of Point Sur. 83 of 85 crewmembers, including all of her Heavier than Air group, survived. The four Sparrowhawks on board went down with her.
Interestingly, the Navy chose not to replace the Akron and Macon, or continue with the construction of the other eight dirigibles, not because of the perceived supremacy of CVs, but because of the rapid advancements in flying boat technologies. Two months after Macon's loss the Consolidated PBY-1 made its first flight. With a flight duration of over 4000 miles, a unit cost of $90,000, and the ability to carry offensive weapons, hundreds of Catalinas were a much better bargain than spending $40,000,000 on ten dirigibles.
