152 H 88 is the name of a series of modernized 152 mm towed heavy howitzers with 32 caliber barrels.

The German 15 cm sFH 18 guns were bought during the Interim Peace and saw service during the Continuation War.

The howitzers use a cased variable charge separate-loading propellant system.

The Soviet type ammunition is usually transported as complete in a wooden box.

The guns can fire high-explosive fragmentation shells, which have a muzzle velocity of about 650 m/s and an effective radius of 50–150 meters.
