The Belgrano was indeed an old Brooklyn class light crusier. It had a great rate of fire due to its five triple-turret main battery. Even in WWII, though, the Brooklyns were considered somewhat flimsy. That a modern torpedo easily took it out is not in the least surprising.

The Belgrano was sunk by a salvo of three Mk 8 torpedoes from HMS Conqueror. Either one or two of these hit. The Mk 8 was an unguided, steam powered torpedo developed in the 1920s.

Why was a modern nuclear submarine using unguided torpedoes designed 60 years ago? Because the "modern" Mk 24 electrically powered homing torpedoes didn't work.

I didn't know that about the Brit torpedoes. Thanks.
