After the recent exercise has shown the need for more recon seplanes and the Chilean navy wanting to build hybrid carriers the Argentine Navy with the aid of Germany has come up with this.
To compare...
Basically a General Belgrano with a large hangar and more modern Argentine AA weapons (the new 115mm and six-barrelled 20mm). Much thicker deck armour too. She should carry 6-8 aircraft. It would operate with 1-2 Light Scout Cruisers and a couple of destroyers.
