The 15 cm hrubá houfnice vz. 25 (Heavy howitzer model 25) was a Czech heavy howitzer used in the Second World War. It was taken into Wehrmacht service as the 15 cm sFH 25(t). Slovakia had 126 in inventory.
Intended to replace the various Austro-Hungarian heavy howitzer that the Czechs had inherited, they began a program to develop a new howitzer shortly after achieving independence in 1919. It didn't reflect many of the lessons of World War I as it retained a box trail and wooden wheels suitable only for horse traction. Its carriage broke down into two loads for transport. It fired a 42 kilograms (93 lb) shell.
