HISTORY
In 2020, the Polish Ministry of National Defence sought a modernizing solution for its fleet of around 500 aging BWP-1. In response, HSW initiated a project originally designated as the LZSSW (Lekki Zdalnie Sterowany System Wieżowy, or Lightweight Remote Controlled Turret System). Drawing on experience gained while developing the heavier ZSSW-30 turret for the Borsuk IFV and Rosomak 8x8, HSW and WB Electronics formed an industrial consortium on September 1, 2021, with PCO S.A. joining in February 2025 to supply advanced optoelectronic fire-control systems.
The initial LZSSW design was strictly constrained by a target mass of under 1,800 kg to preserve the amphibious capabilities and mobility of BWP-1 hulls. The turret featured an external weapons layout, externally mounted armored ammunition boxes, and a completely non-penetrating base requiring no internal turret basket, allowing control consoles to be positioned flexibly inside the host vehicle.
However, the program’s focus changed dramatically following the outbreak of full-scale war in Ukraine. Poland transferred a substantial portion of its active BWP-1 fleet to the Ukrainian Armed Forces as military aid. With significantly fewer vehicles remaining for upgrade and deep retrofits evaluated as economically inefficient, HSW pivoted the LZSSW project away from being solely a BWP-1 upgrade. Instead, the team refocused on creating a highly adaptable, light remote turret intended for international export and integration onto various wheeled or tracked platforms.
Between 2020 and 2024, the turret underwent extensive structural redesigns. The overall layout was reconfigured by relocating the machine gun feed and anti-tank guided missile launcher from the left to the right side of the mount, while the main autocannon ammunition containers and optoelectronic sighting heads were rearranged. By leveraging newer, lighter components and simplifying drive mechanisms, engineers succeeded in trimming the turret’s profile and reducing the overall combat weight of the single-launcher, single-sight configuration to under 1,500 kg.
The turret made its public debut at MSPO 2025 under the designation ZSMU-30, initially displayed on the Waran 4x4 tactical multi-role vehicle. A year later, at MSPO 2026, Polish Armaments Group (PGZ) and HSW officially showcased the ZSMU 30/40 integrated onto the Universal Modular Tracked Platform (UMPG) chassis, the same tracked foundation utilized by the BWP Borsuk. Positioned as a lighter, more cost-effective alternative to the ZSSW-30, the ZSMU 30/40 retains much of its predecessor’s firepower and advanced target tracking while providing a modular, non-penetrating solution for lightweight wheeled and tracked vehicles.

there are two versions of this optic but the difference is that they’re HD-SDI, no data are available for them
