Chiński POW Tan Yang - 28.01.2011

Taki projekt okrętu obrony wybrzeża przygotowała ponoć stocznia Johna Browna dla Chińskiej MW pod koniec Pierwszej Wojny Światowej. Miała to być gładkopokładowa jednostka, wypierająca nieco ponad 10.000 ton, uzbrojona w4 działa 381 mm w wieżach osadzonych na barbetach wystających ponad pokład(analogicznie jak na brytyjskich monitorach), 8 dział 120 mm w kazamatach i rozwijająca prędkość 17 w. Reszta charakterystyk, w tym opancerzenie, to już moja fantazja.

Hipotetyczne nazwy okrętów tego typu: Tan Yang, Fen Yang, Hen Yang, Hui Yang, Hsin Yang, Hua Yang.

Poniższy rysunek to moja przeróbka rysunku tej jednostki,zaprezentowanego przez Blenheima na forum DWS (razem w ww. nazwami okrętów): http://www.dws.org.pl/download/file.php?id=5094  Za udostępnienie go do wykorzystania w moim blogu niniejszym składam autorowi serdeczne podziękowania:-)
