I was cleaning up my office yesterday and found these plans I had made under a pile of papers:
It is for the Brazilian U-17 river monitor named the Parnaiba.
Its the oldest active warship, if you don't count some sailing ships that are still officially commissioned like the HMS Victory. Its undergone some modifications over its 75 years of service, including the addition of a helicopter landing pad.
I am not sure if my plans are 100% accurate. Its based on the few pictures I could find, plus a drawing from Shipbucket.com. Therefore, there was a lot of guessing going on.
I plan to use built one or maybe two for the Southern Chalupastan navy. One, I plan to build as is; the other, I will probably upgrade its main gun. Currently, its sporting a WWII vintage 3" gun, but I might try for a more modern rapid-fire weapon.
