Veinticinco de Mayo, NUS Battleship laid down 1905


Credit for peices used in the making of the artwork goes to 'thesmilingassassin' & 'BrockPaine' @ WPDB.

Rebuilt in 1916:
-erased submerged torpedoes and related misc weight
-bigger bulges, around 1.5m wide each
-internal bulkhead 1.5 inches thick
-increased casemate armor
-heavier machinery as a result of bulging.
-Larger bunkerage. Part as a result of bulging, part to increase range.
-longer main and upper belts than the previous design (the original ship has a too long main belt for the new machinery. By cutting it a bit, same with the upper one, I save armor weight while still keeping all vitals well protected ).

The flush deck remains in place, btw.
