Gotha LD1

   Designed by Rosner, the Gotha LD1 biplane (LD = Land Doppeldecker, or land biplane), powered by a 100 hp Mercedes engine, was ordered on 24 February 1914. It was a conventional, three- bay design with side-mounted radiators. It may have been intended as a competition machine but appears to have remained at Gotha for evaluation and training. During the course of flight trials, the LD 1 received a new rudder and other minor modifications.
   On 31 August 1914 the LD1 was commandeered by officers of Feld-Flieger-Abteilung 4 and subsequently purchased by the Fliegertruppe, which assigned it the designation B.458/14. Only one LD1 was built.
