I donīt want to be involved in the anti-Argentine arguing. Just to point that the Aspides were healthy now.
Electronics, warheads and such were updated back in 2007 / 2008.
Destroyer La Argentina (Meko 360 class) "birds away" on november 2008.
Finally, another little correction, the most modern ship in Argentine Navy (ARA) is ARA Gomez Roca, a Meko 140 corvette active since May 2004 (8 years old).
Again, I am not comparing those ships with a Type 45 and I am not arguing about war and such. I am sure that all of this could be settled with gainings for all parties involved.
Regards!
