TREMOS

Patria TREMOS is an integration module rather than a complete vehicle or a turret: it mounts an existing smoothbore mortar tube and breech, in either 120 mm or 81 mm, onto a host platform and adds the recoil mitigation, ammunition handling and crew stations needed to fire it from the vehicle. Because it reuses the customer's current tube, ammunition and ballistic tables, Patria markets it as a low-cost modernisation path for conventional mortars rather than a clean-sheet weapon. The module is muzzle-loaded and manually laid, traverses plus or minus 185 degrees, and has an active elevation range of +40 to +80 degrees with a maintenance position at -3 degrees. Patria publishes a module-plus-weapon weight of 1,600 to 3,500 kg depending on configuration; because that is the mass of the module and not of any complete vehicle, no combat weight is recorded here, the same convention this catalogue uses for the Patria NEMO turret. Crew is three to four, made up of a commander, a gunner and one or two loaders, with seats available so the crew can remain in their operating positions while the vehicle moves. The system's central claim is shoot-and-scoot performance: it can emplace and open fire within 30 seconds from a known firing position or within 60 seconds from patrol mode, put its first three rounds downrange in 15 seconds, and displace immediately after the last round, since the hydro-pneumatic recoil system removes any need for ground support such as baseplates or stabiliser legs. Maximum rate of fire is 12 rounds per minute and range is published as '7+ km', ammunition dependent, so the recorded range is a manufacturer-stated floor rather than a ceiling. An inertial navigation unit and a weapon terminal with battle management system connectivity provide first-round accuracy; Patria supplies these or accepts them as government-furnished equipment. The modular structure is designed so the whole system can be swapped between vehicles within minutes, and Patria states compatibility with 4x4, 6x6, 8x8 and light tracked platforms. TREMOS was launched in 2025 as the newest member of Patria's 120 mm mortar family alongside NEMO, NEMO Navy and NEMO Container, and has been shown in demonstration firings; no operator orders had been publicly announced as of this record's creation.
