On 29 October, 2024, at the Future Mortar Systems conference in London, UK, Patria launched Patria TREMOS. This robust and cost-effective mortar system increases the mobility and accuracy of trusted, traditional high firepower mortars. Patria TREMOS modernizes conventional mortars with advanced recoil technology, allowing integration into to various types of vehicles and responding to the current and future warfighting and crisis management needs with enhanced mobility, firepower and accuracy. The system can be equipped with an in-service barrel and breech enabling the use of qualified weapon, ammunition and ballistic tables which makes it easy to train and operate. Patria TREMOS expands the advantages of mobility and modern technology to traditional mortars enabling rapid deployment, accurate first round hit and by fast in-and-out of action capability.
“We have developed this new mortar system in close collaboration with the Finnish Defence Forces. After the initial ideas were approved, it took only a year to produce the first prototype for proof-of-concept tests. The main objective was to significantly increase the mobility of an existing mortar equipment. The recent events have highlighted the importance of mobility as the diversity of the battlefield and threat scenarios have increased”, explains Lauri Pauniaho, Director, Weapon Systems at Patria.
The Finnish Defence Forces will acquire a modular 120 mm mortar system from Patria. The procurement involves a pre-series of the new mortar system, set for delivery to the Finnish Army in 2025. The Finnish Army refers to this ongoing project for a new mortar as the 120 KRH M3 mortar system. Patria TREMOS will enhance the survivability to an unpreceded level. Patria TREMOS can be used for all fire missions in infantry fire support. The system combines cost-effectively high firepower and vital shoot-and-scoot capability. Patria TREMOS can open fire within 60 seconds when arriving to the firing position and can leave immediately after the last round is fired. The recoil system reduces the launch stresses and allows firing without the need for ground support enabling immediate exit from firing position after the last round. It can carry all types of needed ammunition and it can be used independently or as part of a larger mobile firing unit.
Patria TREMOS has an integration module with connecting interface making the system fast and easy to integrate and move from one vehicle to another. The mortar system is compatible with all qualified 120 and 81 mm smoothbore mortar ammunitions. The integration module allows the system to be integrated to different suitable types of vehicles such as 4×4, 6×6, 8×8 and light tracked vehicles. The module includes also options to optimize the available space and it can be adapted to customer requirements enabling the most effective use. A solution has been developed also for the ammunition storage making the charge and fuse preparations easy and safe. The Patria TREMOS mortar system meets contemporary requirements of protection through mobility, rapid firepower, and shoot-and-scoot capability. This makes it an excellent option for diverse troops undertaking a variety of missions.
