Let's count commissioned Japanese DDs in WWII:
21 Momi, -4 due to Momi, Kaya, Nashi and Warabi being scrapped or sunk beforehand, shoudl be considered
13 Minekaze
8 Wakatake
9 Kamikaze
12 Mutsuki
24 Fubuki/Ayanami/Akatsuki, -1 due to Miyuki's loss
6 Hatsuharu
10 Shiratsuyu
10 Asashio
18 Kagerou
1 Shimakaze
20 Yuugumo
16 Akizuki
18 Matsu
14 Tachibana (9 more planned)
Total 17 + 13 + 8 + 9 + 12 + 23 + 6 + 10 + 10 + 18 + 1 + 20 + 16 + 18 + 14 = 195 total destroyers in service, 204 planned.
If you count the Momi class being closer to corvettes (they were used as such) it's 178... and Matsu/Tachibana classes are much closer to Black Swans in displacement...
Meanwhile, the US produced:
2 Long Island
4 Avenger
45 Bogue
4 Sangamon
50 Casablanca
21 Commencement Bay (33 planned)
Total 126 (138 planned)
Of course, this was more than all Japanese ships bigger than destroyers, but then you add in the 11 light carriers (9 Independence and 2 Saipan) and... (Langley retired in early 1942)
2 Lexingtons
1 Ranger
3 Yorktowns
1 Wasp
24 Essex (32 planned)
3 Midway (laid down 1943)
Total 34 built in WWII, 42 planned
191 planned total aircraft carriers of all types for US, discounting seaplane tenders and such, compared to 204 Japanese destroyers
Hey, IF you count the Momi class as corvettes by this point, then the US had/had building more carriers in WWII than Japan had/had building destroyers.
EDIT: fixed forgetting to add the CVLs.
