The L 20e α design was a plan for an unknown number of battleships to be built in 1918 for the German navy. The design was selected on 2 October 1917, and construction was to have started 11 September 1918.[67] The ships would have been significantly larger than the preceding Bayern class, at more than 50 m (160 ft) longer than the preceding ships.[68] The ships would have been the first German warship to have mounted guns larger than 16 in (40.6 cm cm).
