Class A (8001 to 13000 ton) cruisers of the Armada

[size=3]Inigo Montoya Class Heavy Cruiser[/size]

These cruisers were laid down under the Cleito Treaty, and were found to have some deficiencies in service - namely an armor belt that did not fully protect the ship's vitals.

The class began 25% refits in 1942 that extended the belt a few metres, improved AA defences, and added a full electronics suite.

[size=3]El Jefe Class Heavy Cruiser[/size]

The El Jefe class heavy cruisers are based more on the Inigo Montoya class heavy cruisers than the Santa Maria class armored cruisers they will actually replace in service.

Although Iberia contemplated something based on the Peruvian Almirante Grau, a few considerations ruled against it:

-Easier logistics from using the same 210mm gun as in the Montoyas

-The quantity of fire is probably better suited to combat against swarms of unarmored, fastish Mexican destroyers than lesser numbers of heavier guns.

-Theoretically, an easier swap-out of triple 210mm for mostly-hypothetical twin automatic 210mm weapons at some future point (Iberia is probably contemplating research in this direction in 1942).

-Expense of a Grau-type ship with an acceptable level of protection.

The class gives up some deck armor, some secondary armament, a half-knot of speed and lesser shell weight to the American Los Angeles class, all of which are considered acceptable. It does have a taller belt, and the light AA is considered to be better.

Leon Class Heavy Cruiser

The Leon class heavy cruisers are, for the most part, incremental improvements on the preceding Jefe class. The primary and obvious difference is that the main armament is not 4x3 210mm, but 4x2 210mm automatic turrets.
