Rather apt timing if I say so myself.
According to one article I read, they put on fake Exocet launchers to make the ship look like it was armed with it:

I asked Barcena if his ship had carried Exocet missiles, and he confirmed that it had, but when I asked Coco the same question, whether the Belgrano had carried Exocets, he laughed and told me that the Belgrano's carpenters had fabricated Exocet launchers out of wood, to make it look as if the cruiser carried the missiles. He added that the Belgrano was not even fitted with sonar.
Although HMS Conqueror was designed long after the Belgrano was, the ship itself was sunk with torpedoes dating from the 1920s (instead of the more modern Tigerfish ones). A vindication of tried and tested technology above something new?
