In this thread I hope to present unbuilt ships of the Polish Navy - both pre- and post-WW2.
Contrary to my previous threads (Polish Coastal Combatants and Amphibious Landing Ships), this one will be updated only infrequently - depending on availability of sources (and on my own mood
).
Of course I invite everyone else with necessary knowledge to participate in this thread as well.
As I have mentioned in the "Amphibious Landing Ships of the Polish Navy" thread, modernization program of the landing flotilla of the Polish Navy officially commenced in 1984, however design studies about potential replacements of the ships in use were underway already since 1977. Initial projects of the Pr.767 medium landing ship (that ultimately become Lublin class) were finished in late 1983 and early 1984:
Pr.767-I project of 1983 was ca. 108m long and 15m wide, with 3130t of displacement at 3,1m draught. It was to be armed with AK-176 76mm gun, two AK-630M 30mm AAAs, 2 Grad 122mm MRLs and 2 Fasta launchers for Strela-2M SAM's. Additionaly it was to be capable of installing 6 launchers of mine-clearing line charges ŁWD-100/5000 Sosna on bow. It was to be propelled with 4 diesel engines Sulzer-Cegielski 16AT-V 25/30D with 3520kW power each, giving it speed of 20 knots. Capacity: 10 T-72 tanks or 17 BMP-1 IFV's and a helicopter pad.
Pr.767-II project of 1984 had same length, but had more narrow hull (13,5m), smaller displacement (2700t) and draught (29,5m). It's engines were to be of the same type as on Pr.767-I, but only two of them, instead of four, so the speed were to be only 16,5 knots. Armament was to be similar, with exception of Grad launchers.
Pr.767-III project of 1984 showed much smaller ship - barely larger than Pr.770: 78m long, 9,7m wide, displacement of 1000t at 2,05m draught. Capable of transporting 5 T-72 tanks (7 if overloaded), it was to be propelled by two diesel engines 40DM (as used on Pr.770/771/773) as armed with 4 ZU-23-2 AAAs, 2 Fasta launchers and up to 6 Sosna launchers.
Among the early studies there were also such concepts as catamarans or dockships, but they didn't proceed beyond preliminary designs. Because 1984 program put forward modified demands, also the three abovementioned projects were dropped and instead a wholly new ship was eventually designed and built.
Around the same time Bulgarian Navy ordered a project of minelayer/landing ship, designated Pr.649, although information about it is rather scarce (I could actually use only one drawing, and almost no text description
).
