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
