TREMOS can be deployed in 30 seconds, fire 12–15 rds/min in MRSI mode, and then redeploy in five seconds. (Patria)
Patria unveiled its TREMOS mortar system on the first day of Defence iQ's Future Mortar Systems (FMS) 2024 conference held in London on 29–30 October.
Patria director for weapon systems Lauri Pauniaho said the system was developed in close co-operation with the Finnish Defence Forces (FDF), taking only a year to produce the first prototype for proof-of-concept tests, with the main objective of increasing the mobility of existing mortars. Designed to provide infantry fire support, TREMOS can open fire in multiple round simultaneous impact (MRSI) mode within 60 seconds of arriving at a firing position and leave immediately after the last round is fired. It has the same recoil system as Patria's Advanced Mortar System (AMOS) to reduce the stress of firing without requiring ground support, allowing it to leave a position after the last round is fired. According to Patria and the FDF, operators can “bring your own barrel (BYOB) and ammunition”, with TREMOS being compatible with all qualified 120 mm and 81 mm smoothbore mortar rounds firing all types of ammunition with fire control using existing firing tables.
TREMOS has an integration module with a connecting interface to facilitate the system's quick integration into vehicles such as 4×4, 6×6, 8×8, and light tracked vehicles and moving it from one vehicle to another using a hooklift.
