Overview for 1948
The Armada de Chile is currently undergoing a period which I call "force refreshment". Overall, I'm working to downsize the force substantially through the means of retiring many old ships and replacing them with new ones. Part of this is driven by the government's desire to reduce overall manpower for the Navy, instead building up a higher degree of technical capabilities.

The most notable aspect of this is in the destroyer fleet. At the beginning of 1947, 32 of Chile's 58 destroyers were foreign-built ships that had been purchased secondhand. Some of these ships, such as the German-built Cerro Fitz Roy class (ex-Lebrecht Maas) are very well-liked and modern. But then there were the old ex-Nordish Temerario class, built in 1922, and the American-built Aldea-class (the ex-Farraguts, also from the 1920s). The experience in refitting the Farraguts caused Chile a bit of heartburn, as the refitted ships aren't really up to the Armada's desired specs even after their rebuild. The result is that the Armada's leadership ruled: no more secondhand purchases - focus on providing new-built ships. This drove the purchase order for the eight Almirante Simpson-class destroyers - the first four of which were laid down in 1947 - and the scrapping of most of the old Temerario-class ships. (OOC: this makes me sad, because I liked the appearance of those old three-stackers.)

The next four Simpson-class ships are on order for 1948, and together with the first four ships, they'll replace the early-1930s ships of the Almirante Lynch and Capitain Thompson-class ships, which form Destroyer Flotilla 1. This is a big deal because it means the Temerario-class is being retired without replacements.

One addition, however, affects Destroyer Flotilla 8. These are the six German-built Maas-class destroyers, which were built in 1938, and which the Chileans think the Germans were crazy to sell, since the Armada loves them. Their size, modernity, and seaworthiness commend them to Chilean service. Unfortunately, there were only six of them, and Chile strongly prefers to use eight-ship flotillas. Therefore, a pair of large destroyers are ordered for 1948 in order to round out the squadron. These two ships, to be named Chacabuco and Maipú, are pretty much new-built photocopies of the Cerro Fitz Roys (the rebuilt Maas design). There are minor tweaks here and there, with the majority of the changes being cosmetic rather than functional. The ships will reuse the A41 guns and turrets from the recently-retired cruisers Concepción and Chillán. (These guns were installed on the two cruisers when they were refitted to Chilean service, and they are judged modern enough for continued use, particularly since they provide a modest cost savings.)

The next thing on the books is a set of refits. The most expensive priority is the aircraft carrier Libertad, which hasn't been updated since her completion in late 1940. Eight years on, she requires an electronics upgrade - and this offers a perfect opportunity to really bring her up to snuff with her stablemate Patria, which received a pair of British steam catapults. The Armada is particularly pleased with Patria's installation, and so, since there's a backup carrier, Libertad has the opportunity for an extended downtime between 1948 and 1949. While the exact extent of Libertad's rebuild is still unclear, I'm thinking a 50% rebuild might actually provide a sufficient benefit in order to allow some growth in miscellaneous weight (necessary for the addition of the desired steam catapults).

And since Libertad is receiving an upgrade, the Armada also wants to cycle her cruiser-cousin Constitución through the yards as well. The Constitución saw a minor refit in 1942 in order to update her original prototype dradis to a more normal production version. A further refinement of that upgrade is planned. This is a relatively cheap upgrade, so Constitución actually beats her cousin into the yard.

The final refit priority falls to some of the very first ships I built when I took up playing Chile: the minesweepers of the DM-1 class. These little ships generally do the yeoman service of coastal patrol, so they've seen a lot of use over the last twelve years, outside the spotlights and behind the stage. They also tend to do a lot of potential ASW surface escort roles. It would take a lot of time and money to replace them, so they will start going in for refits when dock space is available. Among other things, they will receive a navigational dradis (the simple Type 103.1 Nalca, which is used on MTBs and such).

1948 Refit:
- The original tertiary armament - the 1936-dated 3" AA guns - were removed and replaced with 1948-dated 75mm AA guns. (Somewhere I accidentally switched over from an English to a metric design - so I'm going to go with the theory that the 75mm gun is actually an updated mount with better rate-of-fire and elevation capabilities.)
- The ship's electronics were updated. A French Moselle PA search dradis and a Cactus/5 sentry dradis replaced older surface-search and air-search sets. The "Pehuén" main battery fire-control sets were upgraded from the Type 300.0 to the Type 300.2g. The Type 301.1.4 Boldo secondary battery FC sets were upgraded to the Type 301.3.2 models. The ship's hydrophones were also updated.
- As part of the dradis refit, the tripod spotting tops that I loved so much were lost, and replaced by a very similar mast to the one used on the Latorre class cruisers.
- The floatplane complement was reduced to two aircraft (down from three) in order to offset topweight from new electronics.
- Refurbishment of internal fittings.
4744 tons to refit; 7 months.

- 76.2mm deck gun replaced with 75mm deck gun
- Kodkod added
- Excess miscellaneous weight dropped to improve stability.
Refitted 1948 for 64t each.

Just a question on the placement of the Kodkod launchers. I infer that you have the forward 75mm gun in “A” position, and the 40mm mount forward in “B” position. Where are the Kodkod launchers placed? In front of the bridge angled to either side or elsewhere?

Kodkod's a very light fold-up launcher (it's basically Mousetrap) on the forecastle in front of the 75mm gun. It's not expected to be highly effective, but it's expected to be effective enough.

I see... defense is required from the vast submarine fleet of the Marina del Guerra... :D

Well, if that makes the Marina del Guerra's submariners feel more respected, sure. ;)

Commodore Rodney Dangerfield appreciates the gesture...
