How quickly wartime escort carriers could be built

About five months was an exceptionally fast keel-to-commissioning time for Casablanca-class escort carriers, which rules out instant carrier replacement claims.

Question

What was the shortest construction time for an aircraft carrier?

Short answer

About five months for some Casablanca-class escort carriers, an exceptional wartime rate that still took far longer than conspiracy claims allow.

Notes

USS Steamer Bay and USS Lunga Point went from laying down to commissioning in about five months, demonstrating the speed of standardized American wartime production. That achievement applied to small escort carriers built in a mature mass-production program, not fleet carriers. Even this extreme benchmark makes claims of replacing HMS Invincible within days untenable.
