CNS Valparaiso (BB-1913)
Back to Chilean Navy page
The King George V class battleships had performed well during WW1, with the
loss of Audacious to a mine 27/10/1914. The three remaining ships were given to
Chile in replacement for the Canada and Eagle that Britain had retained. The
three ships were given a refit to bring them right up to date and the three
ships sailed for Chile in 1924, right into a large storm of protest from Brazil
and Argentina. Chile obtaining 3 battleships and a battlecruiser (see
CNS Atacama)
in this manner unbalanced the sea power structure of South America. Both
Argentina and Brazil scrambled to obtain new (to them) ships from the sources
available. A second hand battleship race ensued in South America. Of course I
make it even worse by having Wrangel's fleet arrive in Venezuela about the same
time.
Giving the Chilean Navy the ships, Great Britain also looked after the refits
and rebuilds. Tension with Argentina and its Germanic States backers gave the
Commonwealth good reason to look after their satellite countries. 1932 the first
refit schedule to upgrade these ships arrived and the three ships went to
Britain at 4 month intervals. Plans had been made and the artisans went to work
as soon as the ships were docked.
This was the time of the "Queen Anne" mansions that the British were using for
their bridge superstructure. Britain had ordered many 5.5" guns that was
supposed to go to arming cruisers and as secondary armaments for battleships.
Some of the ships they were to arm were cancelled and those guns were available
for fitting to other ships. Ten were earmarked for each of these ships, with
heavy and light AA guns.
Only six years later the class would be back for further alterations. I have to
do this or I can not get the turrets required for the Coquimbo. Each rebuild
took 12 months. The removal of Q turret and its equipment made the extra space
necessary to replace and upgrade the machinery plant. The removal of the 5.5" LA
and 4" HA made space for the 10 twin 4.5" BD mounts to be fitted. (Note: these
4.5" have bag and shell not the fixed ammunition of that other Universes
weapons.) The 2pd weapons in quad mounts were kept but had to be resited to
clear the fire arcs of the 4.5". The 0.5" quad machine guns were kept until the
20mm Oerlikon's arrived. One of the biggest changes was the fitting of a cross
deck catapult, and hangar to operate floatplane aircraft. The fitting of the
dual purpose 4.5" also required the number of AA directors to go from one to
three.

Old drawings. The ideas are good. I like the 5.5" as secondaries as they can be
carried on to rearming the Boadicea class cruisers as well.
I have better bridge structures for late 30's upgrades than the one beloww.
