Four AW101s and a comprehensive integrated logistics and training package to be supplied with PZL-Świdnik acting as prime contractor. With deliveries to be completed by 2022 the fleet will perform Anti-Submarine Warfare and combat search and rescue missions

On April 8, 2019, the Polish Ministry of National Defense signed an offset package worth 395.882751 million zlotys (about $ 104 million) with Italian company Leonardo. This agreement precedes a procurement contract for four Leonardo Helicopters AW101 Merlin for the Polish Navy.

The first Leonardo Merlin HM.2 helicopter fitted with the Crowsnest kit conducted its first flight in late March 2019 at the Leonardo Helicopters (formerly AgustaWestland) site of Yeovil. The Crowsnest kit transforms the Merlin HM.2 of the Royal Navy into an Advanced Early Warning (AEW) helicopter.
