In 1943, the US built more than half as many Fleet carriers as Japan fielded over the entire war (15 vs 28), while also producing an absurd number of escort carriers. In the last year of the war, the US built about as many F6F (Hellcat) fighters as Japan built A6M (Zeros) in the previous 5 years (the F6F is generally considered far superior to the A6M; the F4F is the older contemporary of the A6M).
