Design
The KRH 92 is a conventional 120 mm (4.7 in) smoothbore mortar, with a high tensile-strength steel alloy barrel and baseplate. The KHR 92 is a sturdy weapon and stable in all kinds of terrain. It is designed for quick employment and redeployment: it takes less than a minute to emplace the mortar. The baseplate provides a full 360° traverse without the need of moving it.[3]
Two versions of the KRH 92 were developed: a long-range version capable of firing a mortar bomb (either by simply dropping it inside the barrel or pulling the trigger) at a distance of 8,600 m (28,200 ft) and lighter version with a shorter barrel with a range of 7,300 m (24,000 ft).[3]
The light version, which is the standard 120 mm mortar of the Finnish Army has a shorter barrel, a modified carriage, the bipod is made of high-strength aluminum instead of steel, and the firing mechanism is simplified, being capable of drop firing only. But the firing pin can be retracted by pulling a lever to clear misfires or interrupt firing.[2]
The KRH 92 can be mounted and fired (at a 54° angle) from the trailer unit of a Patria tracked articulated vehicle.[4]
The mortar has seen use during the Russo-Ukrainian War with Ukrainian forces. For security reasons, Finland has not officially disclosed the quantity or exact types of equipment supplied to Ukraine.[5]
