BAS 31 Fixed Artillery Battery

Fixed Artillery Batteries were established after 1945 as part of the concept of creating a strong coastal defense. All batteries were carefully camouflaged. The facilities to ensure operation were hidden in reinforced concrete shelters scattered in the terrain. This provided an advantage in a clash with a warship of similar armament class. The largest concentration of BAS was in the Gdansk Bay area. The expansion of the Fixed Artillery Battery on the Polish coast continued until 1955. Due to a change in the concept of using the Navy under the Warsaw Pact and the development of missile weapons, the batteries were disbanded in 1974.

BAS 31 at Ustron Morski was established in 1954. The complex was deployed east of Ustron Morski. It was operated by Military Unit No. 1437. The battery consisted of 4 naval B-13 cannons of 130mm caliber (barrel length 50 caliber, firing rate 6-10 shots/min.) Standard Zalp-B radar and DM-4 rangefinder. In 1961-1965, the battery was cadeted to the 98-military ethic and subordinated to the Coastal Defense Flotilla. Like the rest of the BAS, it functioned until 1974, and remained under the care of the military in the 1980s. As part of the reduction of the area subordinate to the Navy, BAS 31 became open to the public. Efforts are currently underway to partially renovate the BAS facilities.
