Swedish defence and security company Saab has been awarded a contract by the Polish Armaments Agency to design and build two signals intelligence (SIGINT) ships for the Polish Navy.

Under the contract, announced on 25 November and worth EUR620 million (USD644 million), the two new SIGINT vessels will be delivered in 2027. The scope of supply also includes follow-on support. The vessels are expected to be built at Remontowa Shipbuilding shipyard in Gdańsk, Poland, and then retrofitted with specialist equipment at Saab Kockums' shipyard in Karlskrona, Sweden.

The new ships are being procured under the Polish Navy's Delfin programme as replacements for the service's two Modified Moma-class (Project 863) intelligence-collection ships, ORP Nawigator (262) and ORP Hydrograf (263), which were built by Northern Shipyard, Gdańsk, in the mid-1970s.
