Airborne aircraft carrier

An airborne aircraft carrier is a type of mother ship aircraft which can carry, launch, retrieve and support other smaller aircraft.

The only examples to have been built were airships.

Airborne aircraft carriers also appear in fiction.

USS Akron and Macon[edit]

USS Akron (ZRS-4) and USS Macon (ZRS-5) were two rigid airships built for scouting duties for the U.S. Navy and operational between 1931 and 1933.

Following experiments with launching and recovering small aeroplanes using the USS Los Angeles (ZR-3), the USA designed the Akron and Macon with internal hangars able to house a number of Curtiss F9C Sparrowhawk biplane fighters. The fighters were launched and recovered using a "trapeze" mechanism.[1]

With lengths of 785 ft (239 m), Akron and Macon were among the largest flying objects in the world and still hold the world record for helium-filled airships.[citation needed] They were just 20 ft (6.1 m) shorter than the German hydrogen-filled airship Hindenburg.

Akron first flew on 8 August 1931 and Macon followed on 21 April 1933. The Sparrowhawk fighters became operational in September 1932. Akron was destroyed on 4 April 1934 and Macon on 12 February 1935.[2]

During her accident-prone 18-month term of service, the Akron served as an airborne aircraft carrier for launching and recovering F9C Sparrowhawk fighter planes. Akron was destroyed[3] in a thunderstorm off the coast of New Jersey on the morning of 4 April 1933, killing 73 of her 76 crewmen and passengers. This accident was the largest loss of life for any known airship crash.[4]

Macon was designed to carry biplane parasite aircraft, five single-seat Curtiss F9C Sparrowhawk for scouting or two-seat Fleet N2Y-1 for training. In service for less than two years, in 1935 Macon was damaged in a storm and lost off California's Big Sur coast, though most of the crew were saved. The wreckage is listed as "USS Macon Airship Remains" on the U.S. National Register of Historic Places.

Airship projects[edit]

The British Imperial Airship Scheme of 1924 initially envisaged an airship that could carry five fighter aircraft in military use, but this requirement was abandoned and the project saw only the civilian R100 and R101 airships to completion.[5]

During the 1940s alternate plans were drawn that were not realized.[citation needed] One proposal was for a rigid runway situated on the top of the airship for both take off and landings of planes, and an elevator to move the aircraft into the hangar located inside the main hull.[citation needed] This would allow an airship to field a large amount of aircraft. These plans were abandoned due to weight/lift ratio of the airship and the lost internal gas space (thus reducing the lift) due to the installation of a large hangar.
