In the 1980s Polish
Stocznia Północna (Northern Shipyard) in Gdańsk built a series of degaussing station ships
Pr.130 Bereza for the navies of Soviet Union (18 ships ordered) and Bulgaria (1 ship). However, when the break-up of the Soviet Union occured, the last ship for that country was still only being built and the new Russian Navy was no longer interested in having it finished. For nearly a decade it remained in shipyard which tried to find a buyer, creating a design of a "degaussing and research ship" based on this unfinished hull, with relatively minor changes, mostly in the internal architecture and some of the specialized equipment (although exact configuration of it would depend on the buyer's wishes anyway) under the name Pr.130-I. Ultimately that last vessel was heavily rebuilt into logistical support ship for the Polish Navy, the
ORP Kontradmirał Xawery Czernicki.
The sources for this design are scarce. It should be noted, that the only drawing available to me, coming from the Shipyards promotional publication and published, among others, in the
Nowa Technika Wojskowa 5/2001 was rather blurry but it quite clearly showed the starboard cutter missing, though details of the arrangement looked unclear to me, and I allowed myself to keep it as on the real-life Pr.130's.
