Historic and technical information
Denomination :     15cm sFH 13 L/17 Origin :       ( Krupp)             ( RheinMetall )          

Historic context :

During the war, Krupp proposed a modified version of the famous heavy howitzer'15 cm sFH 13', by extending the tube length from 14 to 17 calibres in order to extend the range without having to use too big propulsive loads, and by extending the dimension of the tube shell chamber so as to decrease the pressure hence the risks for prematures

This modification capitalzed on the experience gained with the 15cm sFH 13 howitzer at war and improved the ballistic properties of the howitzer, for a small sacrifice to a heavier total weight.reduction of rifle grooves and angle was another major change.

This new version was named '15 cm lg sFH 13' ('lg' = 'lange', elongated), and was manufactured to a total quantity of 1550 guns. Its inventories went from 344 in August 1917 to 1080 in November 1918. Many of them survived the WW1 in numerous countries armies.

Contractors manufacturing difficulties for the hydro-pneumatic recoil of the sFH 13 lead Krupp to design a simplified design, based on a hydro-mechanical recuperator and named '15cm lang sFH 13/02', that was produced at about 1000 items. Apart from the recuperator, the main visible differences with the 15cm lg sFH 13 are the lack of gunner and aimer seats, the lack of foldable part of the protection shield, a reinforced carriage and a modified spade. This was meant to be a 15cm sFH 02 modernization, including a change of the barrel
