To put some of the delay imposed by going from a wartime to peacetime schedule into context, the development of the US Navy 3"/50 Mk 27/33/34 mount was slowed significantly.

While the first prototype was rushed into firing ranges by 1 SEP 1945, it took until 1948 for it to end up at sea in quantity.

I have a document somewhere in my huge National Archives trawls saying that they imposed an arbitrary 24 to 36 month delay in the development program around September 1945 to "take the time" to develop a debugged product ready for fleet use.
