Nuclear weapons arrive later without a wartime research coalition

Absent the Manhattan Project's urgency and information pooling, atomic weapons remain research projects into the 1950s rather than reshaping the 1940s fleets.

Notes

Several countries had promising nuclear research but lacked the pressure and coordination that converted it into an operational bomb during World War II. Peacetime funding can continue the work, yet a usable weapon probably does not appear before the 1950s in this scenario. Existing biological stockpiles already provide a form of mutually destructive retaliation, and their existence did not historically prevent conventional war. Nuclear research therefore influences long-term planning without immediately ending competitive battleship, carrier, and guided-weapon programs.
