Ok, here is what CHile has currently in its inventory in a total of:

Ships to be decomitioned (3 County & 3 Leander):
4 Barak (County)
2 SeaCat (Leander)
1 Phalanx (Leander)

Excocet 38MM
Excocet 40MM

Ships to be keept in service (T-22):
2 × Sea Wolf

Excocet 38MM

Ships to be comitioned in the coming years (2 M/2 L Class, 3 T-23):
Seawolf VLS (T-23)
Seasparrow (M/L Class)
Standard SM-1 MR (L Class)
4 goalkeeper (M/L Class)

Harpoon I/II (M/L Class)

Now:

The Excocets are going to be retired over the time to be changed to the Harpoon IIs (makes sence since most of the new units are equiped with them)
Excocets are still going to be used as part of the weapoms inventory for the Superpumas

As for the AA capabilitys:
The Seacat is defenetly going to be retired.
In stock there will be 4 Barak & 1 Phalanx.

The Planes for the T 22 are not completly clear. It is thought to be installed one gun & as you said, the option for renewal of the Sea Wolf are whide.

As for what I have heard so far the idea would be to sell the Baraks & install eather the ESSM or the RAM on the T 22 ( & posibly changing the Sea Sparrow in the M Class to ESSM to in the future).
Also the T 22 would recive the Phalanx.
Finaly the option is analiced to install CIWS on the 3 T 23 which could be eather the Goalkeeper, Phalanx or RAM.

The Supepuma is the standar Embarct Air Unit in the Chilean Navy, so zes. Also Chile has just adquired a 1st bunch of 20 Harpoon IIs (which will start to replace the Excocets).

Finaly Chile doesn’t owne right now the Phalanx Ram, but talks are underway, with the least to get the standart RAM.

Shure, go ahead I will have to scan in some

Well, 150yrs ago the Bow shape was that way becouse they still used to incorporate a spoiler (like the Trirams). By that it was more for a practical reason then a Hydrodynamic (or a Radar Reflecting one ;)).
Like Leon said it, that design is very wet on the forward deck, & that is why it is good for costal & calm waters (the ship cuts through the waves instead of splashing over them), but realy $hity for Blue or stormy sea (which does not mean that it will sink or turn, but that its sailing conditions are worse).

So this design is stable on a forward/back axis, but more instable on the port/starboard one.
The last one isn’t realy a problem since it can be fixed with winglets attachet to the hull, like on the cruise ships.

Regarding the Pic:

I am well aware that hat Pic is from way before the DD 21 was designed, But if you look, you got the DD(X) with the inverted bow for costal, next to it the CG(X) with the same superstrcture & hull arangement then the DD(X) but with a normal bow & the LCS Triram with the invcerted Bow again for costal operations.

So, it wouldn’t be strange if the CG(X) has a normal Bow again for high Bluewater conditions

No, no “new” vessels have arrived in Chile.
As the new vessels arrive, the older (Leanders & spetialy the Countys) will be retired.

The Chilean Navy usualy reuses the same Names for there main surface ships, always having a couple kind in reserve.

So, as new ships arrive, the ones that are not currently used will be given to them (it is very unpropable that all 7 ships will arrive the same time). With the new ships, the names of the retired ones will be availioble & the next comming renamed with them.

The 2 M class FFGs will be named:

FF Almirante Blanco (last ship was a County DDHL tht was retired almost 2 years ago)
FF Riveros (last was a DD that was retired in the late 80s)
both will arive this Dezember.

With there arival most propably the DDHL Almirante Cochrane & Capitan Prat will be retired (both Countys from ’66).
Those 2 names would then pass on to the next vessels that arrive & so on.

On the list then currently:

Almirante Latorre
Almirante Cochrane
Capitan Prat
Almirante Lynch
Almirante Condell
Ministro Zenteno

Those would be the ofitial names, but the ships are then called normaly just Latorre, Cochrane, Prat, Lynch, Condell, Zenteno, Blanco & Riveros

Here is the Pic I was talking of:

BTW: The ARA Santisima Trinidad was not used actifly in the Falklandwar (neather was the rest of the fleet after the ARA Belgrano got sunk). Also Argentina had 2 or 3 Lynx in the Service of there Navy
