[Kaiser Kirk]

I was looking at my old Pirate class for conversion to TB, as you have so many of the those.
Unfortunately re-engining them adds up $ quickly, so I expect I will just refurbish and rearm.
But that means they can't fit ASW.

It is a category I just do not counter terribly well, though I do expect to draft my gunboats
into service if needed, and those do match up.

[Jefgte]

I was looking at my old Pirate class for conversion to TB, as you have so many of the those.
Unfortunately re-engining them adds up $ quickly, so I expect I will just refurbish and rearm.
But that means they can't fit ASW.

It is a category I just do not counter terribly well, though I do expect to draft my gunboats
into service if needed, and those do match up.

Byzance has:
92 DD from 1000t to 1700t - speed 30kts mini. (Fleet Destroyers).
122 TB from 400t to 840t - speed 28kts to 29kts. (Coastal Torpedo Boats).
78 TGB from 500t to 800t - speed 25 to 26kts. (Colonial Torpedo Gun Boats).
