Me wonders that Brazils does not spend any tonnage on repairs. Don´t they repair their ships?
Well, of course there aren´t that many damaged as the entries in the encyclopedia secion has been limited thus not allowing much story writing.
I also wonder how the Brazilian navy will be capable to do their job without all the small units necessary for fleet service. THose small units that also take the biggest punches in a war: escorts, minesweeper, launches, armed trawlers, sloops....
As you´ve expressed the Brazilians hope to win naval battles with their large DDs and fast CLs. Me wonders how they hope to do so once their harbours are mined with the ships trapped inside.
Just a thought of course, hardly more than a "what if"...
