Historic and technical information
Denomination :     7.62cm L/30 RaderFlak (russ.02) Origin :       ( Putilov)             ( Krupp )          

Historic context :

The German victory on Russian armies in Tannenberg in 1914 gave a very impressive loot, including numerous good Russian fieldguns 76.2mm Putilov M1902 and huge stocks of ammunitions. The idea came very quickly to convert these excellent weapons into anti-aircraft guns.

Krupp followed Rheinmetall in 1916 by first adapting the obsolete 7.62cm M1900 Russian guns, then in 1917 more modern 7.62 cm M1902. In the Krupp design, the front half of the Russian trail was kept, and the trunnions left in their original position. This assembly was fixed almost vertically on a carriage, and was protected by an armor plate in front.

The elevation range allowed angles up to 70 degrees, but the direction pointing was only possible by rotating the carriage on its wheels posed on a circular track. The result was therefore far less practical than the Rheinmetall solution, and one had to wait for the arrival of the Krupp SockelFlak devices to finally see this company adapt Russian tubes on pivot carriages.
