Akashi's Improvement Arsenal/Table

Equipment that can be improved depends on the day of the week and the ship in the second slot of the first fleet. The improvement list changes at 0:00 JST, meaning the improvement list would've advanced to the next day after 15:00 UTC+0. This means that Kirishima can no longer upgrade Type 91 AP Shell after 10:00 Eastern Standard Time on Monday as it is already past midnight in Japan.

When the 2nd Ship varies by day, the ship's Initial is used; '✓ ' denotes that any ship can be used.
