Sabre RCWS

Sabre is a remote-controlled weapon station built by Roboneers , a Ukrainian manufacturer that has spent the past decade developing robotic combat modules for the country’s armed forces. The station entered serial production around 2022 and, as Russia’s full-scale invasion ground on, became one of the more visible Ukrainian-built RCWS designs at the front. It is a modular platform: a stabilised cradle, an optronic sight with day camera and thermal channel, a ballistic computer, and a weapon mount that can carry anything from a 7.62 mm PKT machine gun through a 12.7 mm NSV or KPVT up to a 30 mm autocannon or automatic grenade launcher.

The technical heart of the system is its sensor and fire-control package. Two-axis gyrostabilisation keeps the optic and the barrel pointed where the operator wants them while the host vehicle moves or shakes from nearby fire. The thermal imager extends engagement into the night and through obscurants; the ballistic computer accounts for range, ammunition type, and platform tilt. Roboneers has progressively added software that locks onto a target once the operator designates it, then keeps the gun on that point as both the platform and the target move — a step short of full autonomous engagement, but one that significantly compresses the time between detection and shot. Power, sighting, and trigger are all routed through a sealed control unit inside the vehicle, so the gunner can fight from under armour rather than from an exposed mount.

Sabre stations are fielded on Ukrainian light tactical vehicles, on the Ironclad family of ground robots, and as fixed emplacements covering trench lines and observation posts. Ukrainian units have publicised their use in defensive positions along the eastern and southern fronts, where the appeal is straightforward: the gunner is not exposed, the system can hold watch through the night, and the weapon can be cued by drone observers passing target data into the same fire-control loop.

Development has continued through the war. Newer configurations integrate with Ukrainian battle-management software for target hand-off from reconnaissance drones, and Roboneers has shown variants carrying anti-tank guided missile launchers alongside the primary weapon. The Sabre sits in a crowded category internationally — alongside Kongsberg’s Protector and Elbit’s ORCWS — but it is one of the few designs in that class with continuous, large-scale combat use to draw lessons from.
