The SSW40 is intended to provide infantry units with enhanced firepower while maintaining the manoeuvrability of an assault rifle. The weapon is capable of engaging targets at ranges of up to 900 metres and features an airburst capability for counter-drone and behind-cover engagements.
Compared to the conventional 40 mm x 46 low velocity (LV) rounds, MV ammunition delivers a higher velocity and extended range. Rheinmetall states the new ammunition also enables a greater payload and supports programmable airburst functionality, enhancing operational flexibility.
The break-barrel design of the SSW40 allows it to fire longer types of ammunition, positioning it between LV and the more powerful 40 mm x 53 high velocity rounds, which are typically reserved for crew-served launchers. This design broadens the range of missions for which the SSW40 can be deployed.
Weighing around four kilograms and measuring approximately 80 centimetres, the SSW40 is designed with ergonomics and ease of use in mind. “Operating the weapon is quickly comprehendible,” Rheinmetall noted, highlighting features such as ambidextrous controls and a user-friendly recoil system.
At the live demonstration, participants fired both LV and MV rounds using Target Practice Marker-Tracer (TPM-T) ammunition. After firing an initial round with a conventional LV launcher, shooters tested the SSW40 against targets set at distances ranging from 100 to 500 metres, including a wrecked car at 250 metres.
Observers reported that the SSW40 handled similarly to a heavy assault rifle and noted its stability despite the increased pressure of MV rounds. “There was no difference between the two types of ammunition when firing, thanks to the SSW40’s encapsulated, self-regulating hydropneumatic recoil damping system,” Rheinmetall explained.
Aiming was supported by an Aimpoint red-dot sight, and experienced shooters found longer-range targeting achievable with minor adjustments. Participants also praised the weapon’s clean-breaking trigger, which aided in maintaining accuracy.
Rheinmetall expects to complete full qualification of the SSW40 in the fourth quarter of the year. The company also anticipates that the first customer verification will be concluded by the end of 2025.
