[SIZE=3]Overview[/SIZE]

New Construction
With the retirement of the dreadnought Almirante Cochrane, the name has been assigned to the second Blanco Encalada class battlecruiser, started in 1941 (originally named O'Higgins). Construction of this ship will accelerate substantially in 1943.

Blanco Encalada, the lead ship of the class, will complete in February 1943. This new battlecruiser will take on the crew of the retired Almirante Cochrane. It is possible that Almirante Latorre may be retired in the coming year, leaving the Capitan Prat as Chile's sole battleship.

(OOC note: I have been retaining the two Latorres solely due to Peru's possession of the ex-SAE Konigs. Now that those ships are sold to China, albeit not delivered, Chile is downsizing their capital ship fleet to a more realistic size. As the Capitan Prat is the most modern ship in the lineup, with radar, excellent speed, 15" guns, and modern AA, she will be retained as the Navy's flagship. The name Almirante Latorre will similarly be passed on to a new warship of the Armada.)

At least one and possibly two new cruisers will be laid down by ASMAR in 1943. The design, called N1, is classified at present.

The next stage of the destroyer fleet renovation will begin with the American-designed Bolados class escorts. These vessels will be dedicated antisubmarine ships, and will ideally replace the coastal escorts of the Frey, Aldea, or Villaroel classes. As purpose-built surface escorts, the Bolados class will have less armament and speed than purpose-built destroyers, mimicking developments elsewhere in the world.

Refits
Constitucion's 1936-designed radar suite will be refitted to match that of the light cruiser Magellanes. In order to help with topweight, the aft 130mm gun will be replaced with a quad 40mm AA gun.

The destroyers of the Capitan Thompson class will begin midlife refits, receiving new power plants and a comprehensive overhaul. Among the changes will be the removal of some of their depth-charge racks, addition of Colocolo launchers, and the update of radar. These changes will make the Thompson class equivalent to the refitted German-built Voluntarios, which they strongly resemble.

Ongoing Programs
The Armada de Chile's Directorate of Materiel has evaluated the desirability of refitting the three Atacama class cruisers (Atacama, Picunches, and Antofagasta) up to modern standards. With the pending construction of at least one and possibly two N1-type cruisers, the Directorate does not believe potential refit schemes will be cost-effective at this time. Offers for purchase may be entertained in 1943 and 1944. Similarly, the aging carrier Mapuche may be disposed of within the next five years. Design efforts will start to focus on new light cruisers to replace the Atacamas in the 1945 to 1948 period. Replacements are important as seven of Chile's eight light cruisers are over fifteen years old.

Construction of the Star class sea gunboats and YM1942 patrol vessels will continue apace.

Room for accommodation and workspaces is excellent

A very sound and well-reasoned program. It seems well matched to Chile's current needs and capabilities.

The only comment/question is the proposed cruiser design, Los Rios. Admittedly, my thoughts are conditioned somewhat by hindsight, but isn't the design rather small compared with some of Chile's other recent cruisers? The design does not seem to have much stretch.

It is fairly small, yes - particularly by comparison to the nearly 15,000 ton light cruiser Magellanes and the 23,000 ton Constitucion.

In fact, the Los Ríos is very close to the Swedish Tre Kronor class, of which Chile purchased one vessel, and was designed in approximately this period. This represents the bare-bones idea of what I'd want to replace the Atacamas; the Magellanes represents the high end. (I should note that I've not ruled out building the much-delayed second Magellanes class.)

These eight ships were originally intended to be "light destroyers". Over the past few years, the Armada's determined that the Freys are just too slow and too lightly-armed for frontline duties, but most of all, they're some of the worst seaboats in the Navy. This has resulted in their posting in Arica, where the problem is less acute. Strategically, their role is the escort of coastal convoys for protection against submarines and surface raiders. They are not as well-equipped for this role as the Armada would prefer.

In view of this, there's been a proposal to rebuild the class as dedicated fast antisubmarine frigates, equipping them with radar and updated sonar. This results in the ships losing their aft 110mm mount (the Armada feels 2x110mm is more than sufficient to fight any submarine), and seeing their obsolete 4x37mm mounts and the 6x20mm all replaced by two quad 1.1" automatics.

Given the parameters of the original design, the refit proposed does what it can to make the best of the situation. The hulls are comparatively new, and if run at less than flank speed the issue of their being poor seaboats can be minimized. The decision to refit them is probably a good one; in a perfect world, they should be replaced - but Wesworld is not perfect.

And here's a refit of the Almirante Lynch class destroyers. These ships are the leaders attached to the 1st Destroyer Squadron (one Lynch-class DD and three Thompson-class DDs form a destroyer division), and since the Thompsons are undergoing an update, the Lynch class really ought to be modernized at the same time. The refit is very similar to the Thompson refits (see above), but the C turret is removed to help with topweight and space. New engines result in the ship being capable of an extra knot of speed.
