Rigid Airship Designations HMS NO. 1r to 25r and R.26 through R.102
British rigid airships were designated in two fashions. The first had the airship number with a lower case "r" appended to designate a rigid design. This persisted through HMA NO. 25r including two, NO. 14r and 15r which were cancelled. The second nomenclature system applied to all rigid airships from R.26 through R.102. This system had the capital letter R followed by a period and then the sequential number of the airship. The numerals were sequential but there were many which were never more than design designations if at all. Others such as R.41 were contracted for but never finished or In one case (R.81) the contract was never signed. The two major gaps 41 through 79, and 82 through 99 are essentially unexplained. The last R.102 was begun at Cardington but abandoned after the crash of R.101. See: Cis Mowthorp, “Battlebags British Airships of the First World War” pages 157-158.
