15 cm schwere Feldhaubitze M. 15

The first five weapons were delivered in the first half of 1916. A total of 57 barrels and 56 carriages were completed by the end of the war. The Finns purchased twenty weapons after the end of the Winter War. They arrived on the SS Widor on 9 October 1940. They were initially issued to Heavy Artillery Battalions 21, 22 and 28. They were unpopular with the field artillery as they were thought to be too heavy and were withdrawn from field duty during the Continuation War. Some went to equip the Maaselkä Fortification Artillery Battalions.
