Scarcasm aside, one need not be a naval historian/historiographer on the par of Jonathan Parshall or Anthony Tully to know that the US didn't built BBs more or less on par with what the RN had been cranking out for years until the Florida and Texas classes. And only became a leader in architecture with the Nevada class and beyond. As for CVs, in 1941 the USN was one of three peers not a world leader.
In 1941 the USN Yorktown class CVs were approximate peers with the IJN's Shokaku class. It was only with the Essex class - which Japan never answered with an equivalent - the the USN became the world leader, in quality, capability, and number. As the article indicates, the Essexes started coming into the fleet in 1943, and some served in limited roles into the 1970s, IIRC.
Less obvious but still important, 1943 also saw the arrival of the Independence class light carriers (CVL), and late 1942 saw the arrival into service of the escort carriers (CVE). Converting Cleveland class light cruiser hulls to CVLs was an expedient that brought more flight decks into service quicker than using only the Essexes (and Enterprise and Saratoga), and were built in facilities not large enough to build an Essex class CV.
CVEs were based on a tanker design, and while not capable of sailing with CV task groups, they handled tasks for which a CV or CVL would have beenan overkill and poor use of resources (e.g. submarine hunter-killer task groups, invasion landing support, and ferrying aircraft). The IJN also had escort and light carriers that were conversions from commercial ships, but these were less successful, especially on the occasions when the IJN tried to use them in front-line combat roles. Later in the war the IJN used their escort carriers for ferrying aircraft and carrying POWs back to Japan.
Back to the point of article, the numerical and capability advantage advantage the USN built up in WW2 and maintained for many decades can be (and is being, IMO) frittered away.
