Saab Kockums, a shipbuilding company based in Sweden, will design and build two signals intelligence (SIGINT) ships for the Polish Navy. The ships will be built at the Polish shipbuilder Remontowa Shipbuilding’s (formerly Northern Shipyard) shipyard located in Gdansk, Poland.

The ships will replace the Polish Navy’s ageing Project 863 Moma-class radio reconnaissance ships, namely ORP Navigator and ORP Hydrograf, which were built in 1975 and 1976 by Remontowa Shipbuilding.

The construction of the first-of-its-class Saab Naval SIGINT System ship commenced with the steel-cutting ceremony in April 2023.

The keel-laying ceremony for the ship was held in July 2023. The vessel will be named ORP Jerzy Rozycki in honour of the distinguished mathematician who played a significant role in deciphering the German Enigma code.

The ships are expected to be delivered in 2027.

Polish SIGINT ships development timeline

The Polish Ministry of Defence’s Armament Agency awarded a contract worth Skr6.7bn ($642.7m) to Saab for the design, construction, delivery and logistics support of two SIGINT ships as part of the Delfin or Dolphin programme for the Polish Navy in November 2022.

The details of the contract were finalised in December 2022. Saab holds the entire responsibility for the design, production and delivery of the ships, including the integration of the entire advanced mission system onboard.

BSJP | bnt, a Polish law advisor, advised Saab about the signing of the contract.

Saab consequently awarded the shipbuilding contract to Remontowa Shipbuilding, which is responsible for the construction of the ships and will perform the necessary tests.

Signals intelligence ships design details

The ships will be highly reliable and advanced SIGINT-type radioelectronic reconnaissance vessels designed to facilitate the gathering of intelligence data, encompassing a wide range of naval intelligence capabilities.

They will be similar to the new SIGINT ship HMS Artemis, its Swedish counterpart, due to the use of several common designs and technological solutions. They are expected to be approximately 74m long, similar to the HMS Artemis, and feature high autonomy, allowing them to function for extended periods without the need to visit a port.

The ships will undergo Harbour Acceptance Tests and Sea Acceptance Tests sea dock tests, which will be followed by retrofitting with specialised intelligence systems.

Operational details

The vessels are designated for reconnaissance operations, encompassing the examination of their respective regions, along with the compilation of information benefiting their naval forces and intelligence operations, rather than hydrographic undertakings.

Consequently, the ships will prioritise advanced intelligence, surveying, and research apparatuses over substantial armaments, thereby facilitating proficient surveillance of foreign naval assets, vessels, and maritime installations, including harbours, gas terminals, and offshore wind farms.

Saab’s Swedish SIGINT ships details

Saab entered an agreement with the Swedish Defence Material Administration for the supply of a specialised vessel designed for SIGINT purposes in April 2017. The contract was valued at Skr730m.

The 74.6m-long and 14m-wide SIGINT ship HMS Artemis was launched in April 2023 to replace the existing ageing HMS Orion vessel, which was launched in 1984. The SIGINT vessel has a displacement of 3,000 tonnes, featuring 35 cabins and 40 bunks. It features better accommodation facilities aboard with improved electromagnetic compatibility capabilities and manoeuvrability. It is also equipped with sensors for naval intelligence.

The ship is powered by four diesel generators with 990kW output.
