Saab has launched the ORP Jerzy Różycki, the first of two signal intelligence (SIGINT) vessels being built for the Polish Navy under the country’s DELFIN program. The launch ceremony took place on July 1, 2025, at Remontowa Shipbuilding in Gdańsk, with the participation of senior officials from Poland’s Ministry of National Defence, Armaments Agency, Navy, and intelligence directorate.
This milestone follows the initial steel cutting in April 2023 and keel laying in November of the same year. ORP Jerzy Różycki will now enter the next phase of development, which includes the installation of reconnaissance systems and sea trials before its eventual entry into service.
The ship is named after Jerzy Różycki, a renowned Polish cryptologist who, along with Marian Rejewski and Henryk Zygalski, played a key role in breaking the German Enigma code before World War II.
The DELFIN program aims to enhance Poland’s maritime intelligence-gathering capabilities. Saab serves as the main contractor, while Remontowa Shipbuilding is responsible for hull construction. Polish company MMC contributed to the ship’s design, and Saab is managing the delivery and integration of the onboard mission systems. Additional support is being provided by other entities within the Polish defense sector.
Once fully equipped, the vessel will support intelligence collection operations across the full spectrum of maritime electronic signals.
