Two battleships (Yamato and Musashi)
Fleet Admiral Yamamoto was trailing his carriers by several hundred miles from his flagship, the battleship "Yamato", along with five battleships and other warships. We know that one IJN cruiser, the Mogami was sunk at Midway. We know that Admiral Fletcher transferred his flag to a cruiser when Yorktown was abandoned, and later sunk by an I-Boat.
The Germans started WW2 with 6 battleships. One, the Graf Spee was damaged and scuttled in the second month of war.
they had a very small army and only had 23 battleships
They were all sunk or scuttled (intentionally sunk).
Two battleships (Yamato and Musashi)
Two may have been present at the actual fight, but five, including Yamamoto's flagship the YAMATO were several hundred miles at the rear of the carriers.
No. The US Navy did not have that many battleships.
From 1906 to 1944; Britain had about 43 battleships.
six battleships
Japan had 8 battleships built as such and also 4 fast battleships which had been built as battlecruisers but improved between the wars.
Active duty? None. There are no battleships in any current navy, anywhere in the world. The last country to have them was the USA with 4 Iowa Class Battleships that had been upgraded over the years since WW2. USS Iowa, USS Missouri, USS Wisconsin, and USS New Jersey. All were decommissioned in the early 1990's The closest thing (categorically) to a Battleship is Russia's Nuclear powered "BattleCruiser". There are many Battleships still in existence as Museum ships, and a few in mothballs.
I believe that would be the 18.1in 460cm guns of the Japanese battleship Yamato.

The answer is 5.
Because America still had some battleships and all their air crafts
Two Battleships were destroyed at Pearl Harbor, the USS Arizona and the USS Oklahoma.
