with regard to the article that “50,000” planes a year might be produced, the US ultimately produced around 500,000 combat planes during the war, a staggering number.
as for warship production, by 1943 the US was essentially producing an entire new Navy every year. When the USN arrived at Japan for attack it brought sixteen (!!) aircraft carriers. Contrast that with the six en route to Pearl as of this date.
Lesson here: dont pull on superman’s cape
That is fleet carriers. If you count light and escort carriers the number is closer to 100.
