23-class airship
The 23 class were rigid airships produced in the United Kingdom during the First World War. They were designed by Vickers, who also built the first and last of the four ships, with the other two being built by William Beardmore and Company and Armstrong-Whitworth. While the 23 class airships were never used in combat, the four ships provided many hours of valuable training and experimental data for British airship crews and designers. Although a total of 17 of these ships were contemplated at one time, only four were ever built. The 23 class was found to be significantly overweight, leading to its cancellation in favour of the more-refined R23X class.
==Design and development==
Following proposals in July 1915 to order more airships to the same design as the 9r then being built by Vickers, on 28 August Vickers were asked to design a new class of airship based on the 9r. To facilitate rapid mass-production, the same transverse frame design as the 9r were used, but lift was increased by adding an extra bay and by making the nose and tail fuller to accommodate larger gasbags.〔Higham 1961, pp. 131–3〕 Power was provided by four Rolls-Royce Eagles.

Three gondolas were suspended from the keel. The forward gondola contained the control room and one engine driving a pair of swivelling propellors, a second amidships contained two engines each driving a fixed four-bladed pusher propeller on outriggers, and the aft gondola contained the fourth engine driving a single two-bladed pusher propeller and an emergency control car. Ballast and fuel were carried in tanks along the keel. Rudders and elevators were of the cruciform type. The design drawings were approved on 10 October 1915〔Higham 1961 p. 134-5〕
