Mini-Scharnhorst :)

Dzisiejszy okręt to odpowiedź na bułgarskie krążowniki prezentowane 25 sierpnia i 15 września 2024 r. Ten okręt, w założeniu jest mini-Scharnhorstem. Jest oczywiście niemieckiej budowy i posiada ujednolicone uzbrojenie artyleryjskie w postaci 8 dział kal. 17 cm L/40 (takich jak na pancernikach typu Deutschland i Braunschweig). Ich rozmieszczenie jest podobne do wspomnianego niemieckiego krążownika pancernego – 4 działa znajdują się w wieżach na dziobie i rufie, a pozostałe 4 – w kazamatach na śródokręciu. Okręt ma wyporność limitowaną do niespełna 7000 ton, w ramach której udało się uzyskać opancerzenie o grubości 150 mm na burtach, 150 mm na wieżach i 100 mm na kazamatach, prędkość wynoszącą 22 w. i zasięg 5100 Mm. Są to parametry, jak się wydaje, wystarczające jak na przeznaczenie okrętu, tj. do działań na wodach okalających Turcję – Morzu Czarnym, Egejskim i Śródziemnym przeciw krążownikom bułgarskim (ww., hipotetyczne), rosyjskim czy greckim (hipotetyczny typ Antinavarhos Kontouriotis – post z 19 stycznia 2024 r.).
