NEMO

NEMO (NEw MOrtar) is a turreted, remote-controlled 120 mm mortar system built around the weapon, an electrical loading device with manual back-up, the turret, a fire control system and on-board ammunition stowage. The turret itself is unmanned, with a crew of two to three operating from the host platform's chassis compartment. Because it is a turret rather than a complete vehicle, Patria publishes a turret weight of 1,900 kg rather than a combat weight: total system mass depends entirely on the carrying platform, so no single vehicle weight is given here. The turret has full 360-degree traverse and an elevation range of -3 to +85 degrees, opens fire in under 30 seconds, puts its first three rounds downrange in 15 seconds, and can scoot immediately afterwards. Maximum rate of fire is 10 rounds per minute with a sustained rate of 6. Patria states a range of '10+ km' without publishing a precise upper bound, since maximum range depends on the ammunition type fired, so the figure recorded here should be read as a manufacturer-stated floor rather than a ceiling. NEMO's signature capability is Multiple Rounds Simultaneous Impact (MRSI), placing up to five rounds on a single target at the same moment by varying charge and elevation; note that MRSI describes multiple rounds converging on one target, not engagement of multiple separate targets. On-board ammunition stowage is typically quoted at 50 to 60 rounds but varies by carrier and is not published as a fixed figure. NEMO has been integrated on the Patria AMV and other 8x8 and 6x6 wheeled vehicles, tracked chassis, and fast patrol and coastal vessels, and has been ordered by Finland, Slovenia (24 turrets on the Patria AMV), Saudi Arabia (36 turrets on the LAV II) and the United Arab Emirates for naval use. A General Dynamics Land Systems UK Ajax-based NEMO mortar carrier was demonstrated in January 2026 but no UK production order has been confirmed, so the United Kingdom is treated here as an evaluator rather than an operator. A containerised sibling, Patria NEMO Container, mounts the same turret inside a 20-foot ISO container and is documented separately; Patria also markets a NEMO Navy naval application, but publishes the same turret specifications for it as for the base system, so it is not carried here as a separate record.
