Hi RegiaMarina!
The aft turret raised one deck gives to you ship a very «Littorian» flavor! Cheers.

Thanks! I though the same myself!

It does look good, overall more balanced than some of your earlier designs. (I keep saying that, don't I?)
I'll just come back to what is turning out to be my hobby horse on this topic of yours: sensors. You can afford to move your gun directors down to bridge-top level, where they will be better protected (what happens when a shell hits one of those lattice masts?) and more stable, while retaining a better sighting range than the turrets.
This would free up the masts for an early air-search radar set, as well as some major spotlights for night operations. A post-war upgrade of the AA radar fit could include some 2D Soviet aerials like those on Golly's Project 68, or some local variants of US designs.

All in all, this design looks nice for a 1950s AA cruiser, except it needs more radar.

Yeah, about that: Your ship looks very modern for a 1947 IOC. The bridge windows and the hull sides both don't scream cruiser-level armor, and a WW2-era cruiser/raider mission would require at least one armored conning tower forward, ideally a backup aft. The secondary battery (85mm guns) also strikes me as light-weight and unprotected. Compare it with late-war or postwar AA cruisers, where the gun density is much higher due to the very limited chance of hitting a fast-flying aircraft with an unguided timed airburst. Consider that you will be facing (or at least want to deter) the most developed naval air branch in history so far.
The backstory you developed is frankly really nice, but the drawing would fit better with something about a hull left unfinished after 1945 and completed as a dedicated AA escort cruiser, facing the proliferation of fast attack aircraft, and possibly to deal with restricted budgets and scarce armor steel.

It is definitely less powerful in it's secondary battery than most other cruisers, but they are DP guns and the main guns are also DP.

The S-50 class submarines:



Design: -With the commissioning of the S-43 boats into the CCCN fleet, the admiralty had only temporarily filled a gap. After 3 or 4 years, the navy was hopelessly outnumbered. The S-43 class was far from perfect, and the old submarines that had been modernized after the war were in a run down state and literally falling apart. What was needed was a design with respectable capabilities that could be cheaply produced in local yards. The type was determined as a coastal submarine, since this would suffice for service in the shallow waters of the Caribbean. The boats were to be 58 meters long, and displace upwards of 600 tons when submerged. The program called for 16 boats, all of which were laid down.

Armament: Armament was the most important part of the design, and it consisted of 4 x 21-inch torpedo tubes for different kinds of torpedoes. Among the torpedo load were 8 x locally developed Type 18 anti-surface torpedo, which was wire-guided, and 4 x Type 12 multi-purpose torpedo, which could strike both submarine and surface targets. Four boats were fitted to carry 16 multipurpose mines each, in vertical release tubes aft of the conning tower. These boats were slightly longer than the rest of the class. A pair of decoy launching tubes were carried aft, near the rudder and shafts.

Propulsion: Propulsion was intended to be very fuel-efficient and silent, and consisted of a locally developed powertrain. This arrangement was intended to provide over 800 horsepower, and consisted of two shafts each driven by a 400 horsepower CEB/CNMPA diesel engine driving a 150 horsepower electric motor. This arrangement provided 10 knots of speed while on the surface, and dropped to 6 knots while submerged.

Sensors and Processing Systems: The array of antennas on the sub's conning tower consisted of several different devices. There were thermometers, radio antennas, air and surface-search radars, and other condition-measurement instruments. Two of the periscopes were ready for immediate use in the event of combat. One of the periscopes was a reserve, in case the others were unusable or damaged. A central computer system was also a first for the nation, and consisted of data-processing computers for calculating ballistic information for launching torpedoes. These systems were developed locally by the Antilles High-Performance Machinery Bureau, and were based on a Soviet design. Several processor banks transmitted data to visual monitors, and key information was stored over a network of integrated hard drives and disks.

Construction, Service, and Upgrades: The 16 boats of the class were laid down at 2 different yards. 6 were laid down in Port-Au-Prince in Haiti, with the other 10 at the Arsenal de Havana in Cuba. Building started in 1964, and all were completed by the next year. The commissioning of the boats caught the attention of the USN, but the dismissed them as just another "Third-World propaganda tool." They had severely underestimated the capabilities of the boats, and the gap for the CCCN fleet was filled for at least another 2 or 3 years, until longer-range boats could be constructed. They served mostly quietly, except for some patrols off Nicaragua during the civil war there, after which they were slated for a modernization. In 1981, they all went to the yard to receive more modern observation and optical equipment, as well as the replacement of their data processors and computers with more modern systems. Machinery was also reworked to be more quiet, and facilities for torpedo handling were improved to allow use of the most modern torpedo equipment. As of 2016, 12 of the 16 are in service, with the other 4 being sold for scrapping to provide spare parts for the active fleet.

Non-penetrating periscopic video is impossible before 1980. Has to do with seawater and plastics. Might want to goose those diesels a bit, too. 1800 HP on a sub this size gives what? 10 knots surfaced?

Fixed.

The transition from Communism to Democracy

-The Community had always relied on the military and political support of the Soviet Union for essentially it's entire existence... This meant the USSR was practically their lifeline for surviving the United States. However, the Soviet Union was an unstable nation at best. Excessive military spending, among other factors, meant the nation was on the brink of collapse. The USSR collapsed in 1991, leaving the Community isolated on the other side of the world, and facing an ever-growing United States military. The Community thus new that it had to adapt to survive the NATO pressure it was being put under. The nation's people were also tired of communism, and the United States capitalized on this to put pressure on the CCCN government. The government announced that it was beginning talks with the Americans for economic and military cooperation. Communist-era economic policy was lifted, and private business was legalized. The nation began to open it's doors to Western democratic ideals, and with this came the world's most recent technological innovations. The nation used this technology and renewed spirit to modernize and reform itself along the accepted ideals of western culture. Civil liberty and freedoms reached an all time high, as the nation adopted a moderate form of democracy. Freedom of religion, press, speech, and expression were allowed under a new American-style constitution, and for the first time in over 150 years, the people of the Caribbean were once again allowed the right to bear arms. The demand for the nation's products was high in the west, with sugar and cotton being big money-makers. This influx of funds was put towards modernizing both the nation itself and the military. Western influence began to show in the army first, who swapped it's Cold War-era uniforms for modern ones AKM rifles for M-16's, and M-78's for M-60 Pattons. Western equipment completely rearmed the army and air force, and the navy placed orders for ships in Italy, France, and the USA. These actions gave them valuable insight into Western military technology and practices, and joint training exercises helped the armed forces better train themselves in coordination with Western tactics and strategy. In 1992, the nation's government was completely overhauled, it renounced all involvement in Nicaragua, and the nation's name was changed to the Caribbean Federal Republic (CFR). It was the largest military power in Central America besides the USA, which made it the regional protector on behalf of the Western Powers. The next year, it officially joined NATO and the United Nations, and announced that it would discontinue all nuclear weapons production and research if they were allowed to keep their current stockpile of 16 bombs and 8 missiles, along with nearly 24 other nuclear devices of some kind. The UN agreed that it could keep 2/3 of it's current stockpile, to which the CFR reluctantly agreed under the compromise that it would be allowed access to NATO intelligence and military databases. The USA's biggest threat had been neutralized in just a few years, and the CFR would prove to be a valuable ally to the west, contributing military force wherever it was required and keeping the peace in the Caribbean.

-I tend to jump around in time periods a lot in this AU, so some communist-era stuff is still in the works.

Hi, Regia Marina:
4 "red" ssk for the peruvian navy is and odd choice. The MGP since the 1920s is (very) american oriented, and a submarine of a non western slip seems almost impossible (even during the 7 years of leftist administration 1968 to 1975, the Navy prefered 2 (+ 1 for spares) Guppy american submarines and ordered 2 IKL 1100, instead purchasing a Foxtrot, Whiskey or Romeo from the Soviet Union. Only in the 90s the Marines purchased 6 D30 from Belarus, some Mil helicopter and a couple of An-32. Cheers.

Ok. I assume since you are located in Peru you are the foremost expert in this sort of field I will fix it.
