RPN Renown (BB-1939)

1935 and all the treaty restrictions for signatories lapse and you can build
what you want. This would be the round of battleship building that would fight
the Second World War. Once the war started, countries like Panagaea, would no
longer be able to put its resources to big ship construction, destroyers and
escorts would take over the building programs. Only aircraft carriers would
escape the small ship dominance. So what does Panagaea do for its last four
battleships. The first pair are to be laid down in 1935 for completion in
1939-40, the second pair are laid down a year later with completion in 1940-41.
Will they be heavily armed (12x16) with moderate speed (27-28) knots of about
45,000 tons. Or will they be more faster battleship with speeds out to 32-33
knots and retain the 9x16" armament, these would again be out to 45k tons.
Panagaea has had experience with both types previously in the
Retribution/Reprisal classes. One thing that could sway the argument is that
both the Sapphire and Paladin class aircraft carriers are designed to make 32
knots. It would be nice to have capital ships that could keep up. To make the
Reliance design go to 32 knots would require over ten thousand tons of
improvements. Most of the extra tonnage would go in making the hull longer and
finer to take the new machinery to get the hull to go 32 knots.
The end result was a ship 80 foot longer than the Reliance class, all of which
was taken up with the larger machinery systems. The jump to 180,000shp for the
32 knot speed was huge. The engines required to convert the steam from the
boilers to that horsepower were far larger than anything built till that time.
They were eclipsed only a year or so later by the Iowa class that could make 33
knots on their 200,000shp powerplant. Everything about the ships was impressive.
The number of 4.5" turrets increased to thirteen, the light AA armament was
truly impressive with over 90 barrels. But it was the electronic outfit that
made the ships truly potent. Air and sea search radars then the gun directors
all had radar assistance for targeting, and for air attack the 2 pounder
mountings had radar predictors. Come close to these beasts and get your arse
kicked. Which sounds good till they come up against the Japanese and German
giants. At which point they can be very glad their targeting systems are better.
The ships were continually improved through to the 1944 major refits when the
all of the old AA weaponry was removed and replaced with a uniform armament of
twin 40mm Bofors. The aircraft handling facilities were removed and extra ships
boats were placed there, with extra accommodation and AA weapons. Upgraded
search radars and command and control functions improved their capabilities
further. They made the perfect flagships.
