The Airship Development AD1 was a British non-rigid gas-filled advertising airship. The airship had a 60,000 cubic feet (1,700 m3) envelope made by the Reginald Foster Dagnall Company of Guildford. The airship, registered G-FAAX, was erected at the old Cramlington Airship Station near Newcastle where it was test flown on 6 November 1929. It was powered by a 100 hp (75 kW) ABC Hornet four-cylinder piston engine mounted on a three-seater underslung car.
The AD1 was used for advertising and had a 76 by 24 ft (23.2 by 7.3 m) panel on each side for messages. It was dismantled after an accident in June 1931 when a storm tore it from its moorings and damaged the envelope.
