Poland’s First Signal Intelligence Ship (SIGINT) Launched

On 1 July 2025, the launch of Poland’s first SIGINT (signal intelligence) ship from Saab, ORP Jerzy Różycki, took place in Gdańsk, Poland. The launching ceremony was attended by representatives from the Polish Ministry of National Defence, the Polish Armaments Agency, the Polish Headquarters of Marine Technology, the Polish Navy, and the Chief of Reconnaissance and Intelligence Analysis Directorate (J2). This event marked the launch of the first of two SIGINT ships acquired under Poland’s ‘DELFIN’ programme.

The launching of the SIGINT vessel is a significant milestone in its construction process, following the first steel cut in April 2023 and keel laying that November. Before entering service, the ship will be equipped with the necessary reconnaissance systems and will undergo sea trials.

The first ship in the ‘DELFIN’ programme series is named ORP Jerzy Różycki, honouring the mathematician, Cipher Bureau employee, and cryptologist who, during the interwar period, worked with Marian Rejewski and Henryk Zygalski to break the code of the German Enigma encryption machine.

“Today marks a significant milestone with the launch of ORP Jerzy Różycki as a testament to the power of cooperation and shared vision. This project exemplifies how nations around the Baltic Sea, with similar needs and experiences, can come together to develop solutions that benefit us all. It demonstrates the type of advanced technology and capabilities that will be imperative for Europe to stand strong against emerging threats and ensure the safety of our people and societies,” said Micael Johansson, President and CEO of Saab.

Ship-based electronic intelligence systems will enable the acquisition of intelligence data across the entire spectrum of maritime electronic intelligence (SIGINT).

The vessels within the ‘DELFIN’ programme are built by Saab as the prime contractor. Remontowa Shipbuilding S.A. is subcontracted to construct the ships, with Polish company MMC supporting Saab with design work. Saab is fully responsible for supplying and integrating the advanced mission systems. Other entities within the Polish defence industry are also involved in the implementation of the project.
