Um... there aren't any new classes being laid down in 1941...

...but that's because everything this year is either a repeat of existing classes, or a refitted ship. This year, the Chilean Navy is:
- Continuing work on the Blanco Encalada, the Magallanes, and the Battle-class destroyer leaders
- Starting construction on the second and third Saavedra-class auxiliaries
- Building the second tank landing ship (Chacabuco)
- Laying down two more oceanic salvage tugs Valle de la Luna and Lago Jeinimeni)
- Refitting the cruiser Chillán like her sistership Concepción
- Refitting the battlecruiser Capitan Prat
- Refitting four Capitan Eyzaguirre-class destroyers with radar
- Reconstructing four Temerario-class destroyers in a total modernization

There, there, don't worry folks: in 1942, you'll get to see the new Almirante Williams-class destroyers for a change of pace.

The twelve Temerarios were acquired in great haste from Nordmark back during the Peruvian War, when the Chilean Navy wanted more More MORE destroyers. They turned out to be an excellent purchase, as they've got decent enough size, speed, and armament. In other words, the Chilean Navy thinks they're worth a refit, and will spend the next few years bringing the class up to snuff.

The engines will be completely refurbished, and the old 110mm breech-loading guns will be removed and replaced with modern dual-purpose mounts; the 3" AA guns will receive similar replacements. Although weight is budgeted for radar and other electronics, the demand for the available radar sets may result in some ships receiving them later. As second-line units, the Temerarios don't always get the pick.

The Capitan Prat will become the Armada's new flagship following her refit in 1941. The battlecruiser is a tad bit of a vintage vessel, but she's still got the stuff to serve as fleet flagship. However, the Armada wants to remodel her slightly to give her radar and more modern communications equipment, as well as installing the Chilean Navy's standard light and medium AA mounts.

Notes:
Acquired 1940 in trade for battlecruisers Valparaiso and Santiago.
Ship will receive a modest refit in 1940-41 to be brought to these specifications.

Two rebuild options are under consideration for the six Voluntario-class destroyers acquired in Q4/40.

Ideally, the Chilean Navy prefers to maintain eight-ship destroyer squadrons. The twelve Temerario-class throw this preference into a tizzy, and they've been operated in two six-ship destroyer squadrons. One possibility is for four of the Voluntarios to be refitted to operate as division leaders in the Temerario-composed squadrons, bringing them up to size. As the Temerarios have 110mm guns, the Voluntarios would therefore be downgunned to use the 110mm for supply purposes (even though the 130mm DP is preferred by the Navy).

The second rebuild option is just to operate the Voluntarios as another six-ship destroyer squadron, which annoys the Navy's "eight-ship squadron" preference but lets them maintain that lovely 130mm gun aboard.

Im not quite understanding why there would be a supply issue. Not really understanding Chilean destroyer doctrine, this is what I am wondering. If the 130mm gun was kept on these ships for a role as leaders of the Temerario-class, would these flotillas not be operating from bases that would have supply dumps that would have 130mm ammo as that is the preferred ~5" gun of the entire navy? I understand if these flotillas are meant to operate from forward bases that may be limited in the types of ammo carried, but if the 130mm gun is standard secondary gun, why would these bases not have any 130mm rounds?

Most of the destroyer squadrons have a supply vessel which carries, among other things, stocks of ammunition. While Talcahuano (the main fleet base) stocks both 110mm and 130mm and it's not much of a problem to keep either in stock, the Navy doesn't wish to deal with trying to mix both 130mm and 110mm shells aboard the destroyer tenders. Inevitably, someone will get hurried and not notice 130mm shells being transferred to a Temerario...

This is why the Chileans build matched eight-ship classes of DDs. Two ships form a destroyer element, two destroyer elements form a destroyer division, and two destroyer divisions compose a destroyer squadron, preferably with a destroyer tender in support.

ok, that makes sense.

Does 20mm of gun calibre make a difference to the opinion of your Navy?
Do you value gunpower over supply neatness?

Tricky questions to answer, its a cosmetic issue. If you intend to group them then keep the 130mm but if you want them to act as division leaders then 110mm might make life easier.
