23r overflew the surrender of the German submarine fleet at Harwich in November 1918, before being modified for experiments with the three-wire mooring system in March 1919. In November, the experiment was successfully completed with two other manned Camels. First an unmanned, then a manned, Sopwith Camel were launched successfully. In July, experiments were made with parasite fighters, in the hope that they could defend the airship. The shells from the large gun caused the ground crew at Pullham some alarm when they ricochetted off the ground instead of exploding harmlessly. A record flight of 40 hours 8 minutes was made in May 1918, as well as experiments with defensive armament of a 2-pounder 40 mm (1.57 in) QF gun and three machine guns. Despite the airship's identification markings being clearly visible to millions of Londoners, the censors banned publication of the name of the ship. It flew over central London on 6 December, bringing the city to a standstill and generating a wave of patriotic fervour. A 240 hp (180 kW) Maybach engine from the crashed Zeppelin L 33 replaced the Rolls-Royce in a new rear car, this one without emergency controls.Ģ3r flew to RNAS Howden, Yorkshire, on 15 October 1917, and then to RNAS Pulham, Norfolk, on 29 October. The ship was found to have less than the rated lift so the dynamos, bomb gear and furniture were removed to save weight.

The trial flight took place at Barrow on 19 September 1917. Construction was delayed by material shortages (including the shortage of linen caused by the Easter rising in Ireland) and strikes. Operational history 23r Ĭonstruction was begun by Vickers on 1 January 1916. However at this point the Treasury intervened, refusing to allow construction of any more airships until there were sufficient sheds in which to house them. One more ship was ordered from Vickers and two from Beardmore and Armstrong.
In December the Treasury approved construction of sixteen more airships, also agreeing on Government loans for the construction of additional construction sheds. Many of the components for the ships were built by Beardmore and Armstrong. The third, 25r, was ordered from Armstrong-Whitworth at Barlow, North Yorkshire. A second, 24r, was ordered from William Beardmore and Company at Inchinnan, in Renfrewshire, Scotland. One was to be built by Vickers at Barrow-in-Furness, Cumbria. The design drawings were approved on 10 October 1915. Rudders and elevators were of the cruciform type. Ballast and fuel were carried in tanks along the keel. The forward gondola contained the control room and one engine driving a pair of swivelling propellers, 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. Three gondolas were suspended from the keel. The triangular section exterior keel had a widened section amidships incorporating a bomb bay, sleeping quarters, radio room and toilet. Power was provided by four 250 hp (190 kW) Rolls-Royce Eagle engines. The great portion of the 23 class structure was identical to the 9r's.
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. Photograph of 23r taken during the First World Warįollowing 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. The 23 class was found to be significantly overweight, leading to its cancellation in favour of the more-refined R23X class. Although a total of 17 of these ships were contemplated at one time, only four were ever built. 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. The other two were built by William Beardmore and Company and Armstrong-Whitworth. Vickers built the first and last of the four ships. Development of the 23 class began in August 1915 when Vickers was asked to improve the 9r design by increasing its gas capacity by adding a bay and increasing the capacity of the bow and stern gas cells. The 23 class were rigid airships produced in the United Kingdom during the First World War. Vickers ( 23r and R26), Beardmore ( 24r), Armstrong-Whitworth ( 25r)
