Armstrong Whitworth H.M.A. R.33, close up port side of front, emerging from shed, 1919

The R.33 was built by Armstrong Whitworth at Barlow, North Yorkshire, in 1919.

The airship was used in a number of trials carrying aircraft, including a Sopwith Camel, a De Havilland Humming Bird and Gloster Grebe fighters. It was badly damaged at its base in Pulham, Norfolk, but gained a reputation as a lucky airship. In 1926, however, it was discovered that her structure was getting weak. In 1928 the airship was dismantled and the control car preserved, though only the front part has survived.
