The Yamato and Vanguard can go at 38 knots, plus 8 upgraded. Akagi is slower at 33 knots, plus 8 upgraded. Iowa goes at 39 knots, plus 11 upgraded. And the Baltimore can go 43 knots, plus 12 upgraded. Note that I only upgrade until needs gold.

Lucky, Akagi's rebuilds get a boost with 38 knots, plus 8 upgraded.
