question on map numbers

[derflinger58]

I look at the world map and arrow over an area, say southeast asia ; I can see the estimated list of opposing ships ; what do the numbers in () mean? such as usa , 1 BB, 2 CA  (45) ?

did NOT find answer in manual, sorry if this has been answered


thanks for any insight

Its an aggregate strength number, used for judging blockade status.

From what I can tell, the points are as follows: (ships must be in AF to count for points, Workup, Convoy Escort, Mothball, Reserve and Repair all do not count)
1 DD
3 CL
5 CA
8 B
10 BC
12 BB

The 4:1 ratio required to invade colonies is calculated off of this number.
