10.5 cm Feldhaubitze 98/09

The 10.5 cm Feldhaubitze 98/09 (10.5 cm FH 98/09), a short barreled (1625 mm) 105mm howitzer, also referred to as the 10.5 cm leichte Feldhaubitze (light field howitzer) 98/09, was used by Germany in World War I and after. It had a maximum range of 6300 m.

History
It was originally built by Rheinmetall as the 10.5 cm Feldhaubitze 98, an old-fashioned, fixed-recoil weapon delivered to the German army in 1898; between 1902 and 1904, it was redesigned, by Krupp, with a new recoil mechanism and a new carriage. However, it wasn't accepted for service until 1909, hence the ending designation 98/09. Existing weapons were rebuilt to the new standard. As usual, two seats were attached to the gun shield. There were 1,260 in service at the beginning of World War I.

Ammunition
The 10.5 cm used three different types of ammunition and the aiming instruments were marked with three different meter scales and a dial sight for both direct and indirect fire. Originally, it used 7 charges of propellant, but this was increased during the war to 8 in an effort to extend its range.
