Grand Admiral Thrawn

If by "second to none" you mean the Royal navy, you are correct. The US hadn't solved the dispersion problems of its triples, and the 14" guns of the Standards all had different versions, making gunnery that much harder. The US had no scouting wing: either it used the armored cruisers (the Big 10, I believe) with coal and a big silhouette, or the Lexington class, which had very little armor. The South Dakota class was obsolescent; solid for 1916, but the Great War put them on hold, and the designs were never updated. The British would have some problems, as all the battleship classes had different speeds, but since their battlecruisers had speed and armor, they would repeat Jutland and find the enemy first. Finally, the G3 class would have had 7" of deck armor; unheard of at that time. I bet the RN would have built the first 4, then build another 2-4 in late 1920's, depending on how far along when the GD hits. 1930's USN vs Rn, closer (have to go to work, no time to figure out), combination of the WT and USN solving some of the above mentioned problems.
