What Wojskowe Zakłady Łączności Nr 1 S.A. does

Wojskowe Zakłady Łączności Nr 1 S.A. (WZŁ-1 S.A.) is a publicly traded Polish defense contractor, founded in 1955 and headquartered in Zegrze Południowe, Mazowieckie. The company is a member of the state-owned Polska Grupa Zbrojeniowa (PGZ) defense holding and operates as a Spółka Akcyjna (joint-stock company) with declared share capital of PLN 57,692,570. As of end-2023 WZŁ-1 employed 247 staff, a 15% year-on-year increase, concentrated in the Technical Department and Operations to support multi-year program execution. Its core business is the design, manufacture, integration, and lifecycle support of mobile military communication and command systems for the Polish Armed Forces, with secondary exposure to NATO-aligned forces, the Polish Police, and Border Guard.

WZŁ-1's product portfolio centers on shelter-based digital communication centers — including the MCC1/AŁC-T Mobile Communication Center (which interfaces IBCS with national command systems for the WISŁA/Patriot and NAREW air-defense programs), the RWŁC-10/T Mobile Digital Communication Node, the PPTS-1.8 multi-band satellite terminal, the F-OPS Command Cabin, and field cryptographic offices (PKK, RKT) certified up to STRICTLY SECRET. The TRR-8 Tactical Radio Router, designed entirely in Poland, combines routing, network integration, and traffic monitoring across satellite, radio, 4G/5G, WiFi, and Ethernet with AES256 encryption. The company also produces the Mobile Forensic Platform (MPK), Wisła Support Equipment containers (BMC/ISE/SRPT), the MikroSAR Ground Segment for the ICEYE SAR satellite constellation, and the ZWŁC POL CC-121/CC-132 Integrated Digital Communication Center. WZŁ-1 holds unique certifications — NEMP resistance testing accreditation (first in Poland, Dec 2021) and SKW Certificate No. 2/2020 for acoustic attenuation testing — making it the only Polish company with these competencies.

Revenue is generated exclusively through direct government procurement contracts with the Polish Ministry of National Defence (via the Armament Agency/Armament Inspectorate), the Armed Forces Cyberspace Resource Center, and related regional logistics bases. The company participates as prime contractor or core consortium member in flagship programs: WISŁA (Patriot), NAREW, AŁC-T, and MLRS/HIMARS, with disclosed contract values including PLN 880M+ for 43 AŁC-T units (2024-2026), PLN 82M+ for 58 RWŁC-10/T upgrades, PLN 65M+ for 33 PKK shelters, and a PLN 20B+ MLRS framework. Business is built on long-cycle defense tenders with offset commitments tied to international primes (Raytheon, Northrop Grumman, MBDA UK, SMAG, ICEYE, ASELSAN). Ancillary revenue streams include maintenance and training services, satellite bandwidth provision for Polish Military Contingents, and accredited laboratory testing for NEMP and acoustic attenuation.
