German naval infrastructure and the intended war timetable

Did Germany's unstable economy mean the Nazis intended to start the war early?

Not necessarily; the naval construction timetable points later, while economic failures and Hitler's political miscalculation pulled events forward.

The Hamburg dry dock capable of building an H-class battleship was not due until 1942. Allowing at least two years for construction and further time for commissioning pushes an operational ship toward 1945. That physical timetable conflicts with claims that Germany's naval program was designed for an immediate war. Nazi economic dysfunction does not prove coherent short-term planning, because political miscalculation could force conflict before infrastructure and forces were ready.
