Could Scharnhorst have survived North Cape, and what effect would her survival have?
Short answerIf she escaped, she would keep tying down Allied forces and remain vulnerable to bombing; survival until 1945 raises speculative possibilities including a Soviet transfer or atomic testing.
NotesA surviving Scharnhorst would continue to tie down Allied forces. She could become another Tallboy target, although dividing attention between her and Tirpitz offers a speculative route to surviving until 1945. A postwar atomic test is one suggested fate. Transfer to the Soviet Union is another, with her limited fighting power and troublesome high-pressure machinery offered as reasons the Allies might accept that outcome. Where she surrendered or was captured would affect how she was allocated.
