Historic context :
Designed from 1888 to 1893, this 150 mm heavy field howitzer, named 15cm sFH 93 ('sFH' = schwere Feld Haubitze - Heavy field howitzer) was very close to the old guns used during the 1870 Franco-German war : breech loading and rifled bore, but no modern recoil recuperation system (only inclined wooden ramps were placed under the wheels to allow the piece to come back approximately to its firing position after each shot), slow-action breech mechanism.
The noticeable innovations compared to older such guns were mostly a consequence of the visionary demand of the German Army praising for a heavy field artillery weapons design, both powerful and modile. They included the use of Nickel alloyed steel of better performance than bronze for the barrel, allowing both a longer tube without weight increase, and the improved mobility given by a brand new field carriage. Therefore, the 15cm sFH 93 was indeed te be the very first German heavy field gun, concept in which this nation will soon become an expert.
This howitzer was anyway behind its main foreign competitor : in comparaison the French 155mm court Baquet designed earlier in 1890 was not better on the ballistic point of view, but was already equipped with a recoil recuperator that allowed higher firing rates.
In 1914, the old and obsolete 150 sFH 1893 howitzers, however replaced by the 15cm sFH 02 and the 15cm sFH 13 in the active units, were still used in combat as reserve artillery, as one can see on many ancient photographs.
