Nice! Hopefully I don't come across as too negative by pointing out some issues directly
I have only taken a preliminary look at it for now but I do note that some errors still persist. From
fb.asp?m=4200191 the fixes from Sm GM and below in that post are still not in the database. Not a major issue in the big picture, but they should really be done.
E.g. now you are in a situation where the new, fancy Eendracht has 15cm guns that has less penetration than the 14cm guns on the old Japanese cruisers. Yet in reality
all Dutch 15cm guns fired heavier rounds at a higher velocity, so unless they had very defective AP rounds they should without a doubt have better penetration.
Other errors (some inherited):
King George V (005): Same upgrade date as previous King George V slot (004) Issue inherited from stock database. Although the upgrade has no delay or damage or requirements so I'm not sure as to what's up with it.
Nevada (303): Has two slots (14, 15) with Brownings with the same ammo count, facing, and guns per "turret". Only the number is different. No idea what reason there would be to use two slots in this case instead of one slot with the number count added together. Issue inherited from stock database.
Pennsylvania (308, 309): Same as previous, Brownings in slots 12 and 13. Issue inherited from stock database.
West Virgina (336): Same as previous, Brownings in slots 12 and 13. Issue inherited from stock database.
Massachusets (376): Same upgrade date as previous Massachusets slot (375) Issue inherited from stock database.
Admiralty MMS (809): Can Upgrade instantly to APc-1 (810). Inherited from DBB, intentional? At least the bitmap shows a slightly longer vessel fro APc-1.
Tour de Cotes (910): Upgrades to
empty ship class slot 2373.
Eendracht (994, 995, 996): Art is not included in the art file.
Grimsby RAN-I (166): Instantly upgrades to Grimsby RAN-II without delay (this is inherited from DBB). Intended?
Flying Fish (999, 1000): Don't put the mines of a submarine with special mine laying tubes in weapon slot 9. Slot 9 mines are exclusively launched from the torpedo tubes (and should have 0 number, 0 turret, 0 ammo) - or at least I think so. With how you've laid it out at the moment there might be problems using this submarine class for minelaying with the mines in weapon slot 9. The initial version (slot 998) does not have the mines in slot 9 and should therefore work without problems.
Tenryu (1008): Missing ammo for 25mm AA guns (slot 6 and 7).
Kuma (1016): Upgrade available to 1017 directly from start, intended?
Kuma (1017): No upgrade path from 1017 to 1018, probably not intended?
Kitakami (1028): Weapon oddities, you have for example two slots of rear facing DCs (weapon slot 9 and 14) and slot 10 is empty. I'm assuming the intention was to have 25mm AA guns in slots 9 and 10, but check it yourself.
Kitakami (1029): Two slots of Type 13 Radar (slot 7 and 13)
Type C (1317, 1318): Both have the same date (9/43), so if the first ship arrives in 9/43 it'd be able to upgrade instantly, intended?
Type D (1322, 1323): Same upgrade date issue as the Type C.
Shiratsuyu (1458, 1459): Has a right side AAMG (slot 10) without ammo.
Hiryu (1817): Has a 25mm AA slot (6) without ammo.
Hiryu (1819): Upgrades to
empty ship class slot 1820.
Kamishima (1768, 1769): Two first weapon slots references empty device slots.
Following has radars that are not "All Sides" facing. Unsure if this actually matters though.
O16 Class (934)
Nagara (1038)
Mogami (1134)
Shimakaze (1503, 1504, 1505)
Heywood (2540)

Following has ammo for their radars. Does it change anything ingame? I'd guess not. I'll list it anyway:
Colorado (342)
Repeat Benson (520)
Elan (884)
Tenryu (1004, 1005, 1010)
Yubari (1013, 1014)
Kuma (1018, 1019)
Kitakami (1029)
Tokoro (1072, 1073, 1074, 1075)
Minekaze (1411)
Amagi (1739)
Following has data for slots without a device (e.g. a weapon slot with ID = 0, but with say a facing other than "Front", or ammo or something specified anyway). Once again something that probably does not affect the game. Thought I could mention it anyway.
