Launch of ORP Jerzy Różycki: Poland Strengthens Naval SIGINT Capabilities

On July 1st, 2025, Remontowa Shipbuilding S.A. in Gdańsk hosted the christening and launch ceremony of ORP Jerzy Różycki — the first of two modern signals intelligence (SIGINT) vessels being built for the Polish Navy under the "Delfin" program. The event was attended by Polish Deputy Minister of National Defence Paweł Bejda, alongside senior naval officials, defence industry leaders, and representatives from the shipbuilding sector.

- The launch of the first of two signals intelligence vessels for the Polish Armed Forces is a significant enhancement of the Polish Navy’s capabilities. ORP Jerzy Różycki will enable more effective intelligence gathering and strengthen our ability to counter threats in the Baltic Sea. This ship will play a crucial role in ensuring maritime security and will directly support missions such as Baltic Watch, aimed at preventing acts of sabotage and security breaches carried out by the Russian Federation, said Władysław Kosiniak-Kamysz, Deputy Prime Minister and Minister of National Defence.

A New Class of Intelligence Assets in the Baltic

ORP Jerzy Różycki is designed to perform maritime signals intelligence missions (SIGINT), providing real-time collection of electromagnetic spectrum data. These capabilities are critical for enhancing situational awareness in the Baltic Sea region, particularly amid growing hybrid threats and increased Russian military activity.

The ship will serve as a floating intelligence hub, capable of intercepting, analyzing, and disseminating information on radar, communication, and electronic emissions. Intelligence gathered by the vessel will directly support the operational command of the Polish Navy, joint forces, and NATO allies, contributing to regional security and early warning systems.

The "Delfin" Program: Strategic Investment in Naval Intelligence

The "Delfin" program, led by Poland’s Armament Agency (Agencja Uzbrojenia), aims to deliver two advanced SIGINT vessels to the Polish Navy. The construction is carried out by a consortium led by Remontowa Shipbuilding S.A. in partnership with the Polish Armaments Group (PGZ), with key SIGINT systems developed by Polish defence technology companies.

The ships are engineered for long-endurance operations in contested or high-risk maritime environments, providing critical intelligence in both peacetime and crisis scenarios. Their ability to discreetly monitor and collect intelligence on adversary activity supports not only national security but also counter-sabotage efforts, protection of undersea infrastructure, and resilience against hybrid warfare.

A Legacy of Intelligence: Who Was Jerzy Różycki?

The ship’s namesake, Jerzy Różycki (1909–1942), was a renowned Polish mathematician and cryptologist, best known as one of the three key members of the Polish Cipher Bureau team that broke the German Enigma cipher before World War II. Alongside Marian Rejewski and Henryk Zygalski, Różycki laid the foundation for Allied codebreaking efforts that significantly shortened the war.

Różycki tragically died in 1942 when the French passenger ship SS Lamoricière sank in the Mediterranean Sea during a clandestine intelligence mission. Naming the vessel in his honor is a symbolic tribute to Poland’s historic contributions to signals intelligence and highlights the enduring importance of information warfare in modern naval operations.

Embedded in National Security Strategy

The launch of ORP Jerzy Różycki marks a major milestone in the modernization of the Polish Navy, whose role has expanded significantly in recent years amid escalating security challenges in the Baltic region. With Russia’s ongoing activities involving espionage, sabotage, and undersea infrastructure attacks, advanced SIGINT capabilities are now an indispensable component of national defence.

These vessels will also directly support key naval missions such as “Baltic Watch”, which focuses on securing Polish maritime interests, monitoring critical infrastructure, and countering both kinetic and hybrid threats.

Powered by Polish Technology

The "Delfin" program also underscores the growing competence of Poland’s shipbuilding and defence industries in delivering advanced naval technology. The SIGINT vessels feature state-of-the-art sensor arrays, antenna systems, and intelligence processing platforms — all developed in cooperation with domestic defence contractors, enhancing Poland’s technological sovereignty.

ORP Jerzy Różycki is expected to complete outfitting, undergo sea trials, and enter operational service with the Polish Navy in 2027. The second vessel in the program is scheduled for launch and delivery shortly thereafter.
